All the internet gurus are telling you to raise your prices but you don’t want to price yourself out of your market. Episode 5 discusses a simple formula for estimating your expenses that can be customized for any cleaning business.
This episode discusses the politics behind where you buy your chemicals and other supplies. Is is misinformation when a company or internet personality advertises themselves as the ‘little guy’ in order the generate brand loyalty and sales? Whether you buy from a large corporation or the ‘little guy, this episode sheds light on what goes on behind the scenes and the economic engine that shapes the market.
Basic chemicals made simple!
Have you ever wondered why there are so many cleaning chemical choices? Have you ever walked into a cleaning supply store and feel intimidated by all the products? Do you need to use all those products? This episode explains the basics you need for any standard home and commercial cleaning company.
Yes, I’ve decided to do a podcast/video blog. Why? It’s easier than writing a book. Let’s face it, nobody reads anymore and by the time I finished writing my book it would come out just in time for everybody to not read it.
I have a lot of infotainment to offer in the form of behind the scenes industry information and analysis, funny stories and expert industry knowledge. When I hang out with my industry friends and tell my stories they appear to be entertained. If they aren’t’ and they’re just humoring me then this will be a short lived social media experiment.

Mineral Shine is not a film forming acrylic, fluorochemical or solvent. It’s minerals. The minerals seal the pores of the surface, repel stains and add slip resistance.
The mineral film dries to a pH of 11.5 to 12 making it impossible for germs, bacteria, mold and mildew to grow on it’s surface. Not only does Mineral Shine make the surface safer and cleaner but it also eliminates the odor caused by germs, bacteria, mold and mildew.
Mineral Shine will seal almost any hard surface. Concrete, natural stone, synthetic surfaces like porcelain and ceramic, VCT, LVCT, terrazzo and more. Do not use on natural wood.
Mineral Shine is considered permanent, which means that you don’t have to strip it and reapply it. A Rejuvenator solution is applied and scrubbed in to restore the surface if it begins to wear in areas.
Mineral Shine can be applied to vertical surfaces, such as shower walls or kitchen walls to retard the growth of germs, bacteria, mold and mildew.
Mineral Shine will not make a matte surface shiny if you do not buff it, but it can be buffed for a shine if so desired. Even when buffed to a shine, it is still slip resistant. Mineral Shine buffing pads are available to purchase in addition to the Rejuvenator and the Protector solutions.
When used on a waxed VCT floor, all wax must be stripped off. Mineral Shine can be applied to guarded concrete and epoxy floors.
Mineral Shine is incredibly concentrated. Although coverage rates vary depending on the porosity of the surface, users have found tremendous savings in using the Rejuvenator and Protector solutions to maintain their floors and counter tops.
Here is an example of using Mineralshine as a total floor sealer on a ceramic floor.
Here is my own ceramic kitchen floor which I will clean using Mineralshine Rejuvenator/Primer, some degreaser and the Carpet Cleaner America CRB equiped with the optional shampoo tank to give my grout lines a deep scrubbing.
Apply the Mineralshine Protector evenly so that it won’t dry streaky. If you streak it, you’ll have to come behind and buff it.
The floor reflectivity will not be changed unless you put on a few coats and then buff it with diamond impregnated pads. In this case my wife and I like the matte finish look, so there was no polishing done.
Two coats of Mineralshine later…
My floor no has a permenant bacteriastatic coating on it. The mineral film is now a constant pH 11.5 to pH 12. This range of the pH scale makes it impossible for bacteria, germs, mold and viruses to grow and replicate.
Once a year I will clean the floor using the Mineralshine Rejuvenator to refresh the mineral flim. I no longer need to use the Protector on it.

It’s finally summer and the ice has melted, the sun is shining and you see sidewalks and concrete slabs everywhere that have formed fissures and elevated cracks because of ground shifting and moisture from a long wet winter.
These trip hazards need to be fixed and a restoration contractor with a little ‘know how’ can make a tidy sum of money while making the world a little bit safer one concrete slab at a time.
Here is a typical example of a concrete fissure formed by ground shifts and moisture.
You don’t need to be a large concrete grinding operation to tackle jobs like this. Cracks and fissures of this nature form all the time in the driveways of your existing clients, the sidewalks of your commercial accounts and everywhere in your neighborhood where you live.
This blog will show you the steps you need to take in order to effectively fix these hazards while making money doing it.
You might own a weighted 17″ side by side or a large concrete grinder (either planetary or counter rotating) but the most ideal machine for tackling this problem effectively is a scarifier.
One side of the lip of the fissure is raised 3″, so using a weighted side by side and trying to hold it onto one side of the fissure in order to grind down is not only uncomfortable, but ugly. Another good reason not to use a weighted side by side machine when there is an elevation differential is that you will more likely be effecting a larger area, but with a scarifier you can focus on just the crack as opposed to making a 4′ wide swing with a side by side machine. Why expend energy where the crack isn’t. By focusing on the area you can be more efficient and profitable.
Looks like the surface of Mars…
After you’ve gotten both sides the concrete fissure leveled we can begin to smooth out the damage done by the scarifier with a metallic grinding disk.
Using a metal disk to grind will smooth out the concrete and make for a visually attractive repair. If you leave behind scarifier scars then they’ll know you’re a rookie or worse yet, lazy. 🙂
This ugly leveling job was done right in front of the home of Josh Jones, the President of STI Prepmaster and an industry concrete expert. He naturally wanted to jack hammer it out but I told him that the art world might have better appreciation for it…
With the help of his fake dog Ariel, or Argentina or whatever he calls it, Josh used a scarifier to properly level and then he used a grinder to properly grind. He’s sending the bill to his local councilman.
Now let’s get rid of those nasty scars from the scarifier… (scars, scarifier… you see what I did there?) 🙂
You can see that we are using vacuums to keep from making a cloud of silica dust. New laws have been passed requiring a proper vacuum to be hooked up to any silica dust creating machinery. The days of using a plain weighted machine with no dust shroud are gone to dry grind are gone. Making a cloud of silica dust can risk a $5000 fine.
Use self leveling caulk to make sure it will get down into the crevices for deep fissures.
From a large crack with a 3″ height differential on either side we now have a repair that any property manager could be proud of. This is just a basic job, in some cases you have expansion joints to worry about and other engineering considerations.
This is just to show a basic repair that most restoration professionals can do on a driveway, a sidewalk or in this case, a parking lot.

Wood floor cleaning is not for the faint of heart. I’ve written several blogs in the past regarding how to clean wood floors and they all involve water. Water, sometimes with surfactants and organic solvents added are needed to cut through dirt and grime, even on wood floors even though there is potential to damage them.
The problem of using water to clean wood is that wood absorbs water, and if it gets too wet, it can pucker permanently. That has a lot of folks scared because no matter how many classes they take because they don’t want to buy a new wood floor by puckering it up. Sometimes a wood floor is already puckered because of humidity, previous water damage or a previous cleaner using too much water. Using the waterless restoration process will not remove existing puckering, but it won’t make it worse either.
This blog is not meant to discourage the use of water to properly clean wood floors, but to merely offer a safe alternative for those who may be too chicken to put water on wood.
I am not taking credit for inventing this process. I’m just building on the work that others have started in an effort to create a reliable method that is easy to teach and to use.
Bamboo Wood Floor: dirty from new construction, some cupping from water damage, no areas where original finish is worn thin exposing bare wood
This bamboo wood floor is a classic example of not wanting to use water for liability reasons. There was some cupping and warping in some areas yet the polyurethane finish was not worn through in other areas and there was no evidence of water damage.
This home had an abundance of landscaping around it and the home sat low on the property. It was a pretty good chance that moisture from the irrigation system was seeping into the dry foundation and wicking up into the dry wood floor.
Nevertheless, the client wanted the floor ‘refreshed’. It didn’t need to be sanded down, just perked up a little bit. No problem using a counter rotation brush machine (CRB) and dry compound.
The Natri-Dry Compound from Carpet Cleaner America is simply the best dry compound on the market. It’s very chunky, like shredded wheat, so that there aren’t a bunch of little particles to go chasing around.
According to the copy writer at CCA:
The compound is composed of soft, organic particles which are loaded with cleaning agents. It works by delivering these cleaning agents into the carpet fibers by “brushing in” with the CRB machine. The CRB brushes distribute the compound throughout the carpet and clean the fibers in the process. As the soil from the fibers become dissolved, the particles then reabsorb it like miniature sponges. Once this “brushing in” is accomplished, you simply “brush out” or remove it by using the CRB with our Renovator catch tray attachments. It’s extremely simple and easy to use.
For more information visit CCA at http://carpetcleaner-usa.com/products/dry-cleaning-compound/
If you look closely at the pictures above and below you can see some evidence of the cupping and warping that made this job a little risky if water was going to be used. It was much safer and easier to use dry compound and a brush machine to clean before recoating.
Wood floors develop personality over time and this process does not take away dents, deep scratches or scrape marks. What it will do is totally clean the floor and give it back some luster so as to delay a wood sanding job that would be very expensive and only performed by licensed flooring contractors.
Here is another example:
This abused wood floor was years in the making for a good demo.
With the settling of the sub-floor gaps developed between the planks where water would have settled and be absorbed into the wood. This made me very nervous about instructing my client about using a conventional water based cleaner. Using the Natri-Dry Compound on a floor with gaps poses a danger if you do not vacuum or carefully sweep out the gaps. A simply broom sweep over the top isn’t good enough.
Be generous with the compound in proportion to the amount of dirt and grime. The wood fibers infused with solvent can only absorb so much and when they turn dark you are no longer cleaning and you are only spreading the soil around. Bleah.
Move the machine back and forth and side to side rubbing the compound into the polyurethane coating. Over time the dirt particles have stuck to the poly finish like flies to flypaper, but the organic solvent in the Natri-Dry Compound will soften the poly and then release the dirt with friction caused by the action from the counter rotating brushes.
The floor is clean and dry. No water, no puckering, no fear.
In some cases the client will only want their floor cleaned and not ‘coated’. That’s ok. The slight luster that the organic dry compound leaves is from the solvent in the powder moistening the surface and releasing dirt particles that we stuck in the polyurethane like flies on flypaper.
Using a single part water based coating is safer for those who ‘dabble’ in this kind of work. If you really want to be an expert then learn how to apply permanent coatings like solvent based polyurethane or 2 part water based epoxies for wood.
There you go. One waterless wood cleaning restoration square. This demo was a success and the client was very, very happy.
This process will not take dents and dings out of the wood. Wood floors develop ‘personality’ over time. If a client wants a wood floor sanded down, then in most communities this requires a contractors license.
I do want to thank my good friend Dane Gregory for poking me to publish this blog. I’ve sat on it for a few months because I wanted to see some more testing done. In the meantime, others like Mikey from Mikey’s Board have been using this process on the wood floors in the charitable cleaning of Ronald McDonald Houses across the country and others have made comments on Facebook about it, but I decided after reflection that this process is scientifically sound and it takes a lot of pressure off of people who are afraid to do wood floors because of the ‘water’ issue. I also understand from my conversations is Dane that this process is also being tested by certifying authorities on Luxury Vinyl Composite Tile, otherwise known as LVCT.
Thank you for taking a minute to read my blog. My name is Robert Falzone and I have over 30 years of experience in the world of cleaning and restoration. Some of my methods are ‘old school’, some of my methods are ‘new school’ but either way my goal is to take some of the guess work and risks out of the world of cleaning and restoration in a world where risks can mean a big insurance claim if the job is botched.
On the face of it, there are different concrete finishes for different purposes, so knowing your finish and your purpose is imperative for having a successful project. Also you need to take into consideration is that in many instances there is usually an architectural specification for larger projects and you may not be able to choose your methodology, so knowing both the traditional ‘no guard’ process and ‘concrete with guard’ process will be useful so you don’t miss any opportunities that come your way.
Polished concrete is growing in demand as both home builders and commercial engineers & designers are responding to the public’s desire for something architecturally beautiful, yet resilient and wear-resistant. There really isn’t anything else quite like polished concrete to fit that bill.
When done right, a concrete floor with guard compared to naturally shiny concrete floor can look almost identical. So, why would anyone choose one over the other? What are the features and benefits of each method? This article will attempt to shed light on this matter.
What is a concrete guard and where should it be used?
First off, a concrete guard is not a jan-san ‘wax’. It looks like a wax, it’s applied like a wax, but it is in reality a semi-topical, semi-permanent acrylic finish that usually has a chemical component in it, (such as lithium), that allows it to bond to concrete. Guards are not thick and gooey such as a high solids jan-san wax that has 25% solids. Guards are semi-topical and are meant to soak into the concrete but leave a thin protective layer on the top. You aren’t supposed to build up guard with multiple coats, like with a wax.
Guards need to be applied thin because concrete is very hard and almost impossible to scratch, so if you have a thick layer of guard protecting the floor the guard is going to be ‘sacrificed’.
A sacrificial coating is a coating that is meant to be put in harms way. If you drag something across a guarded floor or spill a corrosive chemical, then the guard will take the brunt of the abuse and not the concrete itself.
So, if the concrete is virtually scratch resistant, why apply a guard at all if you can make the concrete shiny and attractive without it?
Using a guard adds a measure of oil/water resistance to the concrete surface. The thin layer on top clogs the concrete pores and oil/water spills will stay on top and not soak into the concrete. This makes guarded floors very popular in supermarkets and box stores. Of course, there are impregnating concrete sealers that are not semi-topical and will repel oil and water too, but in many cases on large projects you are at the mercy of what the architect or builder specifies.
Guard also protects against acid/corrosion stains. Impregnating sealers will prevent surface intrusion of liquids, but they will not prevent a chemical process from occurring. If acid comes into contact with concrete it will eat the calcium and leave a permanent etch mark that will need to be ground out with diamond abrasives. (further in this blog we have an example of this type of etching and how we fixed it)
Also, concrete guards are also known as ‘stain guards’. Some architectural specifications call for decorative stains to be put onto the concrete. The stains sit near the surface and the guard protects the color. If something is then dragged across the floor the guard is sacrificed on behalf of the color stain. In high traffic areas the guard needs to be ground down dull with mild abrasives, then recoated and then re-burnished.
What is the argument against using guard?
It’s not the guard itself that the traditional ‘non-guard’ concrete guys rail against, it’s that some folks in the industry use guard to ‘jump up’ a shine. For instance, some may take a concrete floor that is matte finish and then apply and burnish a guard to make it look like it is polished concrete, when instead all you have is a shiny coating on top of dull/matte concrete. There is nothing wrong with doing that as long as the client knows that this is the process that is being done, but when a shiny guard on dull concrete is ‘sold’ us delivering a polished concrete floor, then you get drama…lots of drama…
Here is a case study where concrete guard is being used in an acceptable manner.
Case study: A concrete floor in a supermarket has been neglected to the point where even when clean, it looks dirty. One of my clients was called upon to provide a solution.
This floor has seen better days. It now always looks dirty because of ingrained soil particles embedded in the guard and the way scratches in the guarded floor reflect light to the human eye. Why did the original contractor apply a guard? Well, you can see the solid stain that is beneath the guard. Guards are meant to guard the color stain with a protective coating so if something is dragged the color isn’t compromised. If no guard was applied, then the topical stain would quickly wear into a traffic pattern and trying to fix a wear pattern in the actual stain is not fun because usually you need to grind it all off and start all over again. if you want the stain to match.
The only way to properly deal with scratched and damaged guard like this is to scrape it down and re-apply, but be careful not to scrape far enough to compromise the color stain. (anymore than it has already been compromised…bleah) Since there is is a danger of scraping away the stain if the grinding process is too aggressive you may want to sacrifice the speed of using an aggressive grit and a dry process for the finesses of using a lighter grit and a wet process.
In this case study we used the STI Spin-1 Pad System, a 50lb. weighted plate and the Mytee HS 300 300 RPM single speed burnisher. For the purpose of this demo, we added some water to the floor, but not too much. This supermarket is almost always open and even when it’s closed there isn’t enough time to empty the shelves from the food products or mask everything off. The safe course is wet and slow, and since I’m a big chicken, we took a little longer and avoided potentially contaminating several thousand dollars of cold cuts, fish and cheese products. (I’d like my salmon fillet with less concrete silica dust please…) Bleah.
Fortunately, the STI Spin-1 Pad System can be used wet or dry. These pads a natural hair and have a special diamond encrusted coating embedded on the ‘business’ side in which the diamond abrasives are held in place to be used on both guarded and unguarded concrete.
These pads from STI are really nifty, but you need to know how to order them. They are called Spin-1 pads. I don’t know why. There is no Spin-2 pad system, Spin-3 pad system blah-blah-blah. (you get the idea) What there is, is a 5 step system or levels of the Spin-1 pad system that are both color coded and numbered. The Spin-1 #1 pad is the coarsest and aggressive, while the Spin-1 #5 pad is for light polishing. You can use them with a high speed burnisher up to 3000 rpm or with a weighted or non-weighted machine at lower rpms. (walk behind jan-san scrubbers too!)
There are too many variables for each floor to determine what number disk and what equipment you would need to accomplish any given task on a floor, so order all 5 so you are covered for any situation. These pads also come in a wide variety of sizes. Just remember to ask your rep for Spin-1 pads, specify the size and the grit level 1-5. Since I’m partially color blind, I won’t even go into the color code system. Even in the picture above, the color I see is ‘bleah’.
The picture belows shows what the floor looks like after the guard is ground down and prepped for re-coating.
Yes, it looks ugly, but we aren’t done yet. The Spin-1 pad #3 did it’s work and scrapped the floor smooth. Even though the light reflects ugly, if you run your hand over the floor you’ll find it smooth to the touch because the blemish marks are not surface residue from the previous guard on top of the floor, but empty voids in the concrete from years of wear exposed by removing the guard. From this point, the only way to get the floor shiny again naturally, without using a guard, would be to keep grinding the concrete down to make the floor smooth and the voids disappear. That is not on the menu tonight. because the client does not want to re-stain the floor. Thus are using a guard to make the floor shiny again.
We applied Sentinel All Surface Floor Guard to this abused concrete floor. This is a great all purpose guard from our friends at Sentinel products.
Once the guard is down and it looks even, let it dry to the touch and then sit for a bit, especially if you did wet grinding and there is some moisture still potentially evaporating from the floor. In a large job site production situation you probably won’t get backed up and have to stop and wait for the floor to dry after wet grinding because you’ll have industrial fans going and a large, industrial surface area etc, but when doing a small demo spot you never want to rush it and risk fogging the guard through water evaporation through the forming acrylic membrane.
We burnished the Sentinel 404 guard with the 300 rpm Mytee HS 300 and a Spin-1 #4 pad dry. (for such a small spot, we didn’t worry about airborne contamination) For a larger scale area, using a 3000 rpm propane burnisher will be more efficient, but be sure to use a vacuum attachment on your polishing machine to ensure that you do not contaminate the atmosphere, especially if you are in an area where you could harm people or contaminate food. Most high speed burnishers have a portal to place a hose attached to a vacuum.
This case study was a success. We achieved all our goals. We were able to scrape away the scratches of the old guard without harming or fading the stain underneath. We did not needlessly contaminate the atmosphere with dust and junk by doing a dry grind. We applied new guard to the floor and burnished it, making it hard and shiny, which gave us an attractive, slip resistant surface that would repel oil stains and prevent bacteria and germs from penetrating into the pores of the concrete and forming colonies of ‘smelly bleah’ that could lead to indoor air pollution from the off-gassing of the bacteria. Finally, we were able to get this process accomplished within a reasonable budget.
Case study: A busy multi-million dollar resort has an unsealed, dingy looking sidewalk in the front that is stained from years of drink spills, gum being mashed into the concrete pores and foot traffic from incoming parking lot foot traffic tracking asphalt oils onto the concrete contributing to the overall ‘bleah’.
While consulting on this job, I suggested doing a good, smooth scrape on the surface of the sidewalk and then coat it with just enough guard to glaze the sidewalk, but not make it too shiny. This plan worked out because they wanted to color sections of the sidewalk with a dark stain, similar to what show in the previous case history in the supermarket.
This sidewalk had a lot of ‘bleah’ going for it. We were going to fix that…
This job required a measure of discretion. We wouldn’t be able to pull up with a large propane powered unit or even a large 220v grinding unit because of the noise a gas powered generator would make. Additionally, with larger, faster moving equipment there is too much drama in dealing with the close proximity of resort clientele, some of who would be entering and exiting the facility in various states of inebriation. The facility didn’t want us building large wooden barriers to cordon off the work area, they wanted us working behind easy to move stanchions and lots and lots of yellow ‘danger’ tape. (which everyone knows is not drunk proof…)
Here we used a heavy floor machine from Hawk. It’s heavy, sturdy, easy to use and operates on 110v electric. The abrasives we used are STI MG2 System (again with the numbers) #3 diamond abrasive disk followed by the STI MG2 #4 abrasive disk. The #3 disk is like the equivalent of a 200 grit diamond grit. We wanted to take a layer off without penetrating the cream layer too deep and exposing the aggregate.
We did wet…again. Even though dust wasn’t an issue outside, the noise was, so we made a little slurry and pushed it aside and then used a slurry vac intermittently to remove the material.
This sidewalk hasn’t been this clean in years. Bleah. This is after 2 steps. #3 and #4 MG2 STI abrasives and a good cleaning.
We put the topical stain on an area of the sidewalk first…
We then added two coats of Sentinel 404 to both areas, but we weren’t done yet.
We used the Mytee 300 RPM HS 300 to do a light burnish without a weighted plate. We wanted to harden the area and buff out any imperfections from mopping down the guard on a sidewalk in the sun. ( Note: I would not have recommended doing this demo in direct sunlight because of potential issues with both the dye and the guard, but the hotel requested it during the day. We did warn them that there we potential cosmetic imperfections by doing this in direct sunlight and they said they were ok with that.)
Ok, now it’s done. The hotel asked when they could walk on it. We told them it was ready for the public to do their worst…(and believe me, they did…)
The facility was impressed that we used equipment that could plug into their 110v external electric outlets, we did not make a lot of noise, no one complained about smells or chemicals. We hit a home run and my client got the job.
NOW WE START TALKING ABOUT NATURAL SHINE CONCRETE WITH NO GUARD…(thank you for your patience…)
Ok, we’ve seen to case studies where using guard was practical, what about the benefits of going ‘au’naturale‘
Guard applied to concrete is ‘semi-topical’ which means that there is a coating on top. This coating is not impervious, it will wear and it can scratch. Naturally polished and densified concrete that does not have that layer of guard on it will not scratch like a guarded floor, (if at all) That being said, there are many guards on the market, and many techniques for using it, but if someone says that they have a guard that performs like naturally polished concrete then they are probably overselling their product.
This sample area was polished shiny the ‘natural way’ and then a section was guarded, so we have guard on top of shiny concrete.
After burnishing the guard and letting it cure I then unscientifically dragged something heavy across it and vola! Had we not put the guard on the surface, we would not have a scratch.
The area where the concrete was shiny and there was no guard was unaffected by the heavy equipment being dragged across it. If you look closely, from this distance you can see the scratch in the guarded area. (it doesn’t look like such a big deal from when you aren’t right on top of it…) Repeatedly dragging equipment across the bare shiny concrete will eventually wear it down, but not as quickly or badly as the shiny guarded floor.
Does this mean that guarded concrete surfaces are inferior? Nope. just different. If I took an acid based diet Coke and spilled it across both areas I’d have a nasty, permanent etch mark/stain on the unguarded, natural portion while I could let the Coke sit on the guarded area for a few days without too much drama. The acid in soft drinks will eat the calcium in concrete but will not eat the acrylic of the guard.
Here is an example of an unguarded concrete floor with acid etch stains.
This garage floor was stained, but not guarded. Stain by itself will not seal a floor, and eventually whatever acid drama was happening in this garage, (this is Las Vegas and I have a strict ‘don’t ask, don’t tell’ policy…) came into contact with the calcium in the concrete and we had a big fat mess.
Yeah, that’s ugly…or really beautiful if you are into abstract art.
These acid stain are no problem if you know how to fix them…
In this case, cost was a factor, so I consulted with my client and suggested that we do on step of diamond grinding to get rid of the acid stains, then guard the floor, then burnish the guard.
Normally you want to put guard on top of shiny concrete, but since this was not the Taj Mahal my client was able to please the property manager and score a nice job repairing acid stained garage floors.
You can still see the scratch marks from the diamond abrasives, but the property owner was ok with that. They wanted to pay for as few steps as possible. If they really wanted to save money they should have sealed/guarded it properly the first time.
So where is it practical to prep concrete floors cosmetically without using guard?
Glad you asked…
Large, industrial surfaces…
Ugly, old epoxy…bleah…
Polished to a natural sheen, not too slippery-shiny, but very easy to maintain. Sweep it, mop it, forget about it. (photos courtesy Kevin Hawthorne)
I don’t know what the end use is for this floor. A museum maybe? But this environment is the perfect place to put down an invisible, impregnating sealer and avoid scratches that will interfere with the artistic reflection of light. (photo courtesy Kevin Hawthorne)
Is it possible to misuse guard in an industrial situation?
Here is a big time fail for a large, industrial surface. This stadium facility was finished with an architectural epoxy terrazzo floor. Epoxy terrazzo is synthetic, thus there is no calcium carbonate and it will not etch. Also, because of it’s synthetic nature, epoxy terrazzo is naturally slip resistant no matter how shiny. Think of it as real hard plastic. Can it stain? Sure there are micro pores that need to be cleaned out if the contractor didn’t seal the air pockets during the installation process using an STI groutpan, but the plastic itself will not stain. Sooooooooo…why did they guard it?
I’m just there to fix the floor, not pass judgement. (I’m not a judgey guy…)All I know is that because the contractor finished with a guard, they made a footprint and scratch nightmare that gave the maintenance crew fits. Can you imagine being the cleaning manager in charge of removed scruffs and scratches from several thousand square feet of bleah on a nightly basis??? Can you imagine what the building management was thinking after being sold on a low maintenance, scruff resistant epoxy resin terrazzo floor and instead getting a high maintenance scruff attracting guarded floor? Bleah.
I was called upon to consult on this job. I said we need to grind off the guard and start shining the floor up from scratch. The facility owners didn’t like that assessment, but the truth is the truth.
This job took 8 steps. We had to grind through the ooey-gooey-sticky guard to get down to dull, bare, epoxy terrazzo and then work back up to a bright shine. The STI Mg2 pad system is 8 steps and we had to use every one of them to fix this floor.
The result was a slip resistant, scruff resistant, scratch free shine. Sure, after a big concert there are plenty of scruff marks, but those marks are from shoe material leaving matter behind on the floor, not damage to the surface. When the maintenance crew uses plain water, a red pad and a standard jan-san walk behind they get back to the epoxy terazoshine instead of having to do multiple steps of polishing to grind the damage out of the guard. There is going to be periodic maintenance on the floor due to all the traffic, but only using the higher grits of the MG2 pad system, not the lower ones.
Can badly scratched guard be repaired?
Yes. The standard way to polish guard is to use a diamond encrusted pad with a high speed burnisher. That’s POLISH, not scratch removal. Sometimes the guard damage is beyond what a diamond encrusted pad can do because of deeply embedded damage.
Here we have a guarded floor in a test area in our warehouse. It started off nice and shiny, but after some months the shine wore away and scratches appeared. We used the Durashine System and the OnFloor Durashine machine to fix it. The nifty unit is 110v and perfect for those hotel or casino lobbies that need to be shined up, but you can’t bring in your propane or 220v monster grinder. It’s 110v whisper quiet and every concrete maintenance polishing company should have one in their arsenal. You can use hard Durashine diamond abrasive pads 50 grit to 3000 or diamond encrusted pads like the STI Spin-1 pad system.
What make the 110v electric Durashine System by Onfloor unique is that it will let you use hard diamond abrasive goods in lieu of the diamond encrusted natural hair pads so you can more aggressively polish both guarded and natural shine floors. Pictured here are the Durashine high speed diamond pads.
While you can put a shine back onto damaged guard, be prepared to put down another coat if there are any areas where the guard has worn all the way thru to the bare concrete.
Architectural shiny residential floors do not necessarily need to be guarded. An impregnator will sit below the surface and thus the floor sans guard will not scratch from pet toenails, moving furniture, skateboards ect.
This floor is an example of a floor covering rip out and instead of replace the floor covering the existing concrete underneath was polished.
This floor was also dyed in the process of polishing. Another blog will discuss the art of dyeing concrete floors.
Polished concrete in homes is very artsy and progressive…
Yep. Now that the concrete is polished you can put down an exotic rug down, maybe even change the rugs out for different seasons. There is a lot of seasonal interior design work you can do with a nice concrete floor and a rotating set of fine carpets. Notice how the cracks and areas where the aggregate is closer to the top add to the personality of the floor and are not treated as undesirable imperfections. No two concrete floors are alike. You can also see a faint outline where the tiles were previously on the floor before they were demolished. It’s like art. No guard, no scratches, no problem. (photos courtesy Ken Fellows)
Are there any circumstances in which it may be appropriate or advantageous to guard a concrete floor in a residential setting?
Sure. Here is a floor where the owner wanted a topical stain and a sacrificial coating of guard would be needed to protect the color.
The homeowner wanted more of a solid color on the floor instead of the typical translucent acetone based dyes. If you use a penetrating translucent dye then you can use impregnators, but if you put down a topical stain, then you are guarding the floor.
Under some circumstances, if the floor didn’t need to be demolished and was in good enough shape, you might not even need to grind it at all, depending on the exact circumstances.
A client of mine had the ugliest garage floor in town. Bleah. He asked me for some help to get is looking spiffy again.
We cleaned it real good with an acid etching solution (to open the pores) and then put down a topical stain with an ordinary pump sprayer.
After you use a pump sprayer for a job like this, you should never use it for anything else ever again. You can never really get rid of all the dye out of the sprayer after you’ve used it this way.
Use a bristle broom to move the dye around a little bit and obliterate the spray patterns. The same advice goes for using a broom like this, either keep it as part of your concrete tools arsenal or throw it away. That dye gets everywhere and into everything.
After the dye is dry, put down one or two layers of concrete guard to protect the dye. If you want to make it shiny, then you can burnish it, but if a semi-gloss guard finish is acceptable then you can leave it be.
What made this a ‘no grind’ situation is the surface integrity of the floor. It was already flat and mostly smooth, just really, really stained. Now it’s smooth and attractive, almost too attractive for a garage floor…
Did you learn anything?
So, are you a natural shine grinder who hates on the contractors who may do a few less mechanical steps with abrasives and then guard? Are you a blow and go ‘guard shiner’ who sells the job to the client as if they are going to get a natural concrete shine and then give them a cheaper guarded shine with hardly any mechanical work being done?
As this blog shows, there is more to concrete surface prep than merely making the floor shiny, we need to access the needs of the client and give them the floor that will best suit their needs. Therefore, we shouldn’t hate on an honest contractor who correctly represents himself as to the procedures he uses to accomplish the client’s desired look.
The concrete surface prep industry is very segmented. Part of the concrete industry is involved in new construction and installing new concrete floors in both commercial and residential settings. Then there are the contractors who do remodels. They are the ones who come in and remove/demo a floor covering and polish the concrete they find under what they demo, and then there are the maintenance contractors who repair the existing floor to it’s original shine, as opposed to attempting to change the overall nature of the floor.

Anyone who knows me knows that I am hard to please. I enjoy doing things the right way, but I also like doing tasks quickly and efficiently. Some ‘old school’ commercial cleaners who may still think that the best approach for commercial cleaning involves bonnets, portables, fans and walk-behind shampoo machines need to open up their minds to new possibilites and new technologies.
I recently had the chance to use the Karcher Micro-Scrubber system in a variety of situations in conjuntion with our ‘world famous’ Bridgepoint chemistry. Some situations were ‘real life’ demonstrations in the field on real jobs and others were staged in and around our store in Las Vegas. I have come to the conclusion that when utilized in the right situation, with the correct chemistry, the Karcher Mirco-Scrubber system can have a positive impact on the field of commercial cleaning.
The Karcher Micro-Scrubber can be used on commercial VCT, natural stone floors, ceramic tile floors, concrete, and finally, low-pile commercial carpet. Yes, you heard me. The Karcher Micro-Scrubber, under the right circumstances, is a great choice to encapsulate carpet. It will never replace a BrushPro, but it’s two gallon fresh water tank is a great way to dispense Bridgepoint Encapuclean as you eat up miles of commercial carpet in an office building, hotel or other commercial facility.
I put together a little video to demonstrate the varieties of uses of the Karcher Micro-Scrubber.
As you saw in the video, underneath the machine are two cylindrical brushes that can be changed out rather easily. There are several different brush types and you need the correct one to get your job done right. Karcher has a very stiff concrete brush, a mid-level brush for stone and a very soft carpet brush.
If you plan on using the Karcher as a dual purpose machine for both carpet AND hard surface machine, then you will need to purchase an additional brush set.
The Karcher Micro-Scrubber comes with a standard brush set, which is for hard surfaces. In my opinion, it is worth the extra money to order the carpet brush set because even if you don’t plan on encapsulating carpet, you will eventually come across a commercial job that will have some carpet and you’ll be glad you had the brushes in your warehouse.
Like the brushes that swap out, there is a rubber squeegee set that is used with the vacuum system for hard surface cleaning can be changed out for stainless steel vacuum bars that allow the machine to be used to clean carpet. I guess the designers originally meant for the Micro-Scrubber to be used with traditional carpet chemistry because the vacuum is meant to pick up solution from the carpet.
When you are using the Karcher Micro-Scrubber for low moisture encapsulation, you will have no need for the vacuum and the purpose of the vacuum bars is only to assist in the gliding of the unit across the carpet.
Still, it’s nice to know that if you are in a commercial situation and you have a ‘bio-hazard’ with the commercial carpet, such as vomit or urine, you can use the Karcher Micro-Scrubber as a traditional carpet extractor just by turning the vacuum on. The unit will dispense carpet rinse, the brushes will agitate and the vacuum will suck it up, just like a traditional extractor. Turn the vacuum off, and you are back to encapsulation.
This is a great value because when you are doing an encapsulation job and you have an area that is hammered and needs to be extracted, you can use Bridgepoint FLEX or TRAFFIC SLAM as a pre-spray in the affected areas and then rinse with the pH 5 Encapuclean02 that is already in your tank for low-moisture encapsulation. Genius! Leave that smelly, beat up old portable in your workshop, you have a Karcher Micro-Scrubber on the job!
That being said, not all carpets can be encapsulated efficiently with the Karcher Micro-Scrubber. The Karcher does best with low-pile commercial carpets that do not shed, (such as carpet tiles) and that’s ok because there are miles of low-pile commercial carpet tiles out there to clean.
The Karcher Micro-Scrubber will not work well with the BrushPro Dry Powder system and it will not pick up debris like the BrusPro with the renovator attachments, so if you plan on buying a Karcher Mirco-Scrubber for encapsulation only, then you should consider buying a BrushPro to go along with it as a ‘pile lifter’. I used the Karcher on a ‘low pile’ wool carpet in a hotel and while it encapsulated just fine, there were still some ‘carpet boogers’ that won’t pick up with the vacuum and it required the use of a BrushPro with renovators to pick the boogers up efficiently.
In a hypothetical situation where a BrushPro is being used as a pile lifter alonside a Karcher Micro-Scrubber being used as an encapsulator, an employee can run ahead with a BrushPro and pile-lift the carpet, pickup loose debris and then the Karcher Micro-Scrubber can come behind with it’s 2 gallon tank and quickly encapsulate an area.
Also, while the majority of square footage on a commercial carpet job can be cleaned with liquid encapulant only, there are still some areas, such as outside a lunch room or in the main lobby that could use the extra love that only the BrushPro Dry Powder system can offer.
Now there may be some of you out there that haven’t used a BrushPro yet and you may not realize how effective the renovator attachments are for removing debris from the carpet. Here is a picture of what got pulled out of the carpet in my own home AFTER using a very expensive vacuum first. Pile-lifting the carpet in advance of encapsulation is both necessary and beneficial.
The main reason you want a BrushPro working alongside the Karcher Micro-Scrubber, is that after you do the carpet and put the BrushPro aside, you still have income earning opportunities with the Karcher Micro-Scrubber.
The Karcher Micro-Scrubber, when used in conjunction with the Bridgepoint Viper Concrete Cleaning System EATS UP commercial concrete. You can do a sidewalk, a driveway, a loading dock, or any other commercial concrete application that you can think of with the same machine that can encapsulate the carpet.
The Karcher Micro-Scrubber can also be used with the Spinergy Stone Polishing system. Whether your are in a residential mansion using the Spinergy Stone system to polish travertine or a swanky office building working hard to make their marble floors shine, the Karcher Micro-Scrubber is a GREAT tool for picking up the slurry from the Spinergy diamond encrusted polishing pads.
You may be thinking that since you already own a portable with a hard surface wand you don’t need this machine to pick up the stone slurry. Let me tell you, the Karcher is WAY easier to setup and use than a portable for picking up stone slurry. The brush action means that you don’t need to flood the floor with water to get the encrusted slurry to move. The two gallons of fresh rinse water in the Karcher tank will go a long way on a stone job. It’s also a lot quieter than a portable and it is easier to change out the dirty water with the ‘picnic basket’ handle design. It also looks nice and neat, which means a LOT when you are in a fancy home with wealthy customers.
Another way to use the Karcher Micro-Scrubber is at night is to maintain VCT floors. VCT stands for vinyl composite tile. It’s those squares that are all over at supermarkets and 7-11’s. It’s everywhere. If you say ‘no’ to cleaning commercial VCT then you are giving up a valuable source of income.
If you are doing commercial carpet in a bank or office building, then the employee break room is probably either going to be VCT or ceramic tile. You can try to drag a mile of truckmount hose up 3 flights of stairs or wrestle with the setup of an auto-dump, auto fill high pressure portable, or you can change out the encapsulation brushes on the Karcher Micro-Scrubber for the hard surface brushes and zip out a break room and a couple of bathrooms without breaking a sweat.
If you are looking for a Karcher scrubber to use as an encapsulation machine that has more range and is battery powered, you can choose between some great walk-behinds and even a ride-on machine!
At the end of the day, you can be sure that if you are interested in doing commercial cleaning, then your local Interlink Supply has something for you.
Remember, instead of buying equipment and then frantically trying to bid on work to match your equipment, go a look at commercial jobs you want to bid on and then find out what kind of equipment is being used there right now. Then, ask yourself is there a quicker, more efficient way of getting the job done, maybe something that you can put in your bid to give you the edge?
Is your level of education up to the task of putting competitive commercial bids together in your market? Do you need to join a program like Larry Cooper’s PCR Network? Goto Larry’s website at www.pcrnetwork.com and maybe Larry can assist you in getting the jobs you want in the commercial field.
The equipment is only part of the equation when working in the commercial field. Using Bridgepoint chemistry available at Interlink Supply will give you the options you need to do commercial cleaning. Whether you are using the Viper Concrete system, the Spinergy Stone system, the Encapuclean low-moisture encapsulation system, or the BrushPro Dry Powder system, you can be sure that your commercial clients are going to be impressed with the crisp cleanliness that only high quality Bridgepoint products can bring to the job.

Started off early in the week making some calls about our new product, Pine Boost. (for info on Pine Boost click here) Pine Boost is made from pine oil and works like our most popular product, Citrus Solv. It will never replace Citrus Solv but for those who are interested in saving a buck, you can’t go wrong. It’s a strong cleaner and it has a fresh odor. Since it is made from pine oil instead of citrus oil, it is not as expensive to make, therefore we pass the savings off to our valued customers. Pine Boost dissolves grease and oil like a champ so don’t judge it by the idea that less expensive means it doesn’t work. (think of all those unused Christmas trees that need recycling, we get the raw materials for Pine Boost cheaper than oranges for Citrus Solv)
Customers who are currently buying less expensive solvent boosters that are made from odorless mineral spirits with a pinch of citrus or some other deodorizer added will be VERY impressed with how Pine Boost compares to the discount brands out there. Anyone who knows me knows I don’t like being wrong. I use products before I promote them because I don’t want to be embarrassed by a dud, and my bosses up in Salt Lake feel the same way. We wouldn’t put a product on the market that didn’t get the job done. Trust me, the next time you are inclined to slink over to a low-budget store and purchase a bargain priced, no-name solvent booster, come by Interlink Supply and pick up a bottle of Pine Boost and walk out of the store instead of sneaking out.
I also had a good experience with helping a customer who bought an M1200 Hydroforce 1200 psi portable from me a couple of months ago. I sold them a high pressure portable with an SX-12 Tile Spinner because they had a lot of hard surfaces to clean. Well, they got a bid on a 25,000 sq. ft. commercial carpet job to do over the weekend and all they had was a plain vanilla two jet carpet wand. (can you say ‘back surgery’?) They called me to consult and I advised them to use a rotary extraction tool. As a veteran of cleaning I am well used to the RX-20 from Hydramaster, but I have a HOSS machine from Sapphire sitting in the front and I really haven’t used it all that much. I wanted to see how the HOSS would perform on 25,000 ft. of soiled, stained, low pile commercial carpet with a cold water portable. I brought in the project manager and some of the techs and we practiced in our classroom for an hour or so with the HOSS. As I conducted the class I considered the 25,000 sq. ft. carpet job. I was worried that the cold water M1200 might not produce enough bang in getting the stains and soil out of the carpet and I didn’t want them to use high pH chemistry. In a commercial glue down carpet situation I am loathe to use a high pH detergent rinse because of the danger of wicking and using a standard, neutralizing acid rinse may not be enough to get the dirt and soil to jump up and out.
Looking at their purchase history I had an idea. They regularly use Encapuclean02 to encapsulate carpet. Encapuclean02 can also be used as an acid rinse and it has hydrogen peroxide in it to kill germs and disappear stains. If you get some on your fingers it burns just like Urine Stain Remover, so you know it’s strong. Since they had a case of this product in their warehouse already, I suggested they use it instead of a detergent rinse or FabSet. Well, the combonation of the HOSS machine, the M1200 auto fill, auto dump portable and Encap02 was a hit! They didn’t even use a detergent prespray, they just ran with the rotary cleaning HOSS and the rinse. The HOSS probably provided enough friction to encapsulate while it was scrubbing and the peroxide killed germs and stains. I am now actively promoting Encapuclean02 as an acid rinse to those who want more ‘pop’ in their rinse. Click on the following link for the spec sheet. It makes for a fascinating read as to how versatile this product is.
The untold story of the ISSA was that I had Rob Hanks luggage in the back of my car, so I was driving to the Convention Center to drop it off to him when a car went on fire right in front of me. Now Rob Hanks is a great guy, very understanding, but he’s still the Big Boss, so you don’t want to make too many excuses when he’s sitting outside in the sun waiting for his luggage, especially when you called a half hour earlier to tell him to meet you in the front to get those bags. I called him back and told him a car blew up in front of me. He’s like, ‘WHAT!’ Later on, when watching the video that I took on my cell phone I realized that the tires were blowing up and exploding from the heat. Well, when the light turned green and some of other cars in front of me started going past real slooow, rubber-necking, (looking for a corpse of something) I was yelling out the window ‘go go go!’. Either stop and don’t go past the burning car or you go past it as quickly as possible in case there is a secondary explosion. So after a few of the lookie-loos went by very slowly the cops came and stopped me just as I was about to gun it. It seemed kind of a trite excuse to tell them, “I have my boss’s luggage is in the back and he’s waiting for me.” while a car is burning to the ground only a few feet away. I don’t think the officer would have responded, “Oh well, in that case, do a 100 mph past the burning wreck and see you again real soon.” Resigned to watch the show, I took a picture to remember the occasion and to show the Rob that it really happened.
Oh yeah, back to work. Interlink of Las Vegas supported another customer who had a successful job at a local hotel encapping with Encapuclean02. Yes, I know that all this success is boring. I’ll save you the eye fatigue reading. You already know the story. Here is the picture.
To finish the week, Kim and I took another deposit for yet another Hydramaster truckmount. Don’t worry Sapphire and Prochem. A new 370SS is being delivered on Monday and we had lunch with a customer today who told us he wants to buy a new Prochem by the end of the year. Interlink rocks!
Here’s a final picture of diner we had with Kim Heiman, our treasured store mentor who has been in town to assist our store this week. We went to Claim Jumper in Henderson. (hee-hee) That’s why I love Interlink. Family friendly, even after hours.
Check in with me after this weekend. We will have wrap-up for the month and I have some new pics with stories I am working on! Thanks for reading!
