We stock more colors then any contractor we know. In addition, we will order any one of hundreds of color choices. We carry team colors for all major colleges and professional sports teams as well as some major corporate colors such as Harley Davidson. We have the unique ability to custom blend paint chips in any color giving you a “one and only” floor.  We can order not only any color, but different sizes of paint chips to achieve the exact look you are going for. Most contractors can only access 3-15 colors and in only one size paint chip.[/vc_column_text][/vc_accordion_tab][vc_accordion_tab title=” I have seen epoxy floors that have peeled off the concrete in many areas, will yours do that?”][vc_column_text]Our floors will not peel, and we warranty it from doing so. Epoxy peels due to inferior concrete preparation as well as inferior product. SCC only uses professional grade concrete preparation equipment. We have the concrete preparation knowledge to ensure your floor will remain intact through out its lifespan. There are a few extremely rare exceptions that are out of our control such as disasters, but you may read about them in our warranty. We offer the strongest warranties in our industry.[/vc_column_text][/vc_accordion_tab][vc_accordion_tab title=”I have seen epoxy floors that have changed color to an ugly yellow. Will yours do that?”][vc_column_text]Our floors will not yellow. SCC uses the highest grade “professional use only” U.V. stable clear coats. Our products have been extensively laboratory and field tested. Our products have been in real world service for decades. The same products that we will install on your project have been installed nationally in commercial and industrial environments such as theme parks, warehouses, and restaurants.  As our industry grows, so does the technology of the coatings. We install products with the newest technologies available.[/vc_column_text][/vc_accordion_tab][vc_accordion_tab title=”Is and epoxy floor coating something that I can do myself? “][vc_column_text]It would be very difficult to achieve a durable, long lasting floor for a first timer. Equally, it would be difficult to achieve a floor that is aesthetically beautiful. There are several reasons. Let’s take a look.

Equipment You would need to rent the correct professional grinders and dust collectors. You would need 3 different grinders as well as have Diamond bits with the correct compounds and design profile. Additionally, you would need to own or purchase items such as respirators, gloves, spike shoes, 18” rollers, roller poles, brushes, mixing buckets, paddles, gloves, masking supplies, etc. To purchase all this stuff for one-time use is unreasonable and cost prohibitive.

Products Home improvement store (HIS) or paint store epoxy coatings kits are vastly inferior to that of professional grade epoxy products. They are formulated for “ease of use” to allow the first timer plenty of working time rather than strength and durability. The physical properties of the home improvement store epoxy do not have the abrasion, chemical, or impact resistance as that of professional grade epoxy. The (HIS) store epoxy will not last very long and will start to peel, chip, crack, and yellow in short order. Would you paint your house with spray paint? You get the picture. Aside from this, the amount of epoxy and paint chip these kits give you is shameful. They instruct you to spread the epoxy unreasonably thin to make it appear that coating an entire garage is affordable. They give you a sandwich baggie full of paint chip which is technically enough to cover about one (1) square foot. Additionally, many kits do not have a clear coat included. When they do, the same holds true for the clear coat. Inferior product and not enough product. With a limited amount of product, your concrete will have very limited protection. Lastly, the price is astronomical. If you were to install the same amount of product that SCC installs on your floor, your cost of (HIS) products would cost you a small fortune.

Concrete Preparation We all know that substrate preparation is key to any successful job regardless of the project or the industry. If you do not know how to prepare or profile your concrete correctly, even professional grade epoxy will not achieve a strong bond to concrete, let alone the home improvement store epoxy.[/vc_column_text][/vc_accordion_tab][vc_accordion_tab title=”How long will it take to install my floor?”][vc_column_text]In general, it will take 1.5 to 2 days to install an epoxy floor. It is possible to install a floor in 1 day with the use of accelerants added into the epoxy. The amount of time it takes to install a floor is variant on certain aspects such as existing moisture content in the concrete or structural damage within the concrete.[/vc_column_text][/vc_accordion_tab][vc_accordion_tab title=”How long after the floor is completed can I walk on my floor?”][vc_column_text]You may walk on your floor 24 hours after the floor has been completed. We suggest a minimum of 48 hours before moving heavy items back in such as washing machines and steel shelving. Many contractors may tell you it is ok to move heavy items back in after 24 hours and technically this is acceptable. 24 hours is acceptable with our products as well however, we do not recommend this as all epoxy and clear coats regardless of brand reach their final physical properties (full cure) in 7 days. The problem here is that many contractors tell you 24 hours as an added appeal of their product, which will increase their sales. If you move your heavy items in prematurely and damage your floor, the contractor is not going to warranty or repair the damage as this would be considered customer neglect.[/vc_column_text][/vc_accordion_tab][vc_accordion_tab title=”Will my house look like a war zone during and after construction? “][vc_column_text]We know that many contractors leave behind a filthy mess. SCC takes pride in our cleanliness and professionalism. We operate the latest in equipment technologies.

Without a warranty, sales pitches and speeches are just words without meaning. Contractors that have confidence in their products and services offer warranties. Choose a company with a strong warranty that makes you feel safe. Walk away from a company that does not offer a warranty.[/vc_column_text][/vc_accordion_tab][vc_accordion_tab title=” How do you prepare the concrete to receive the epoxy?”][vc_column_text]2b: Do you grind the concrete, Shot-blast the concrete, Acid Wash the concrete, or Pressure Wash the concrete?

 

The only recommended methods of preparing concrete to receive a thin build epoxy floor coating is Diamond Grinding or Shot Blasting the concrete.

 

Shot-Blasting (Explanation)

Shot blasting is a process whereas a Shot blasting machine throws metal balls at the concrete to abrade the concrete. Shot blasting open the pores of the concrete and is a good and accepted concrete preparation method, however there are inherent problems with shot blasting. Due to the velocity and force in which these machines throw these heavy metal balls, shot blasting has been documented to create hairline fractures or micro cracking in the concrete. These micro-cracks or micro-fractures can lead to large cracks as the concrete experiences movement, expansion and contraction. This is the same scenario as a tiny hairline crack in an automobile windshield that grows into large cracks as the glass experiences movement. Micro-cracking your concrete now, may lead to major cracks in the concrete as well as the tearing of the epoxy coating in the future. The second problem with shot-blasting is these machines are operated in straight lines. This can cause lines or stripes to show through the epoxy coating. 

 

Diamond Grinding (Explanation)

Diamond Grinding concrete is the best and most suitable method for concrete that will be receiving an epoxy coating. Diamond grinding opens the pores of the concrete which enables the epoxy coating to penetrate the concrete which allows the epoxy coating to form a monolithic and tenacious bond with the concrete. Diamond grinding also levels the concrete eliminating most of the highs and lows within the concrete. Diamond grinding will not leave lines in your floor like shot-blasting does as the walk behind grinder is operated in a circular side to side, back and forth motion.

 

Acid Washing (Explanation)

Acid washing should be avoided at all cost. Acid washing is a process where as a chemical etching agent such as muriatic or phosphoric acid is sprayed onto concrete, then brushed with a broom, then washed off with water. It was developed for indoor facilities such as hospitals or laboratories that need an epoxy floor installed but cannot have any dust whatsoever. Acid etching has many inherent problems.

 

Acid etching merely etches concrete. It does not open the pores of concrete. The goal of acid etching is to give smooth concrete some type of profile (highs and lows) for the epoxy to bond to. It gives the concrete surface a light profile like that of sand paper. Acid etching will allow the epoxy to “hold on” to the surface as where grinding and shot blasting allows the epoxy to embed itself into the concrete and become one with the concrete. When acid etched, the epoxy will have minimal bond to the concrete. This bond is suitable for foot traffic. It is not recommended for garage or warehouse environments that encounter automobile or forklift traffic.

 

There are other problems with Acid-etching. Acid etching will add 1-2 days onto the installation process. This is due to the concrete having to dry after etching and rinsing with water. Introducing high volumes of water to concrete 24 hours before applying epoxy is also a bad idea as the concrete may possess moisture that is difficult to detect. (Side note: If a contractor does not own a grinder, it is highly doubtful they own a concrete moisture tester.) If the epoxy coating is installed with moisture in the concrete, the epoxy may bubble and blister. If this were to happen, the epoxy coating will have to cycle through the curing process, then the floor will have to be ripped out, and then start all over again. This will take 3 more days. Most importantly, if the contractor acid washed the floor originally, this means they do not own a grinder to rip out the epoxy floor. You will be stranded with a bubbled and blistered epoxy floor the contractor is unable to repair. Caution! You may find it very difficult to get the original contractor to pay a different contractor to repair his work. This will cost twice as much because the entire floor must be completely removed and a replaced with a new floor. The original contractor will be “upside down” in the project financially. It is also rather embarrassing to have a professional contractor come to fix the same work that was not originally performed correctly. Hopefully the original contractor would honor their commitment to you and remedy the situation, however if they choose to walk out on you, you will have to deal with the headache and possibly expense of having your floor replaced.

 Additionally, Acid is corrosive and will rust or degrade any item that it unintentionally encounters. It is not good for the environment and must be washed out of a garage, thus it can eventually make its way to our storm drains.

 

In truth, the only reason why a contractor would Acid wash is because they do not own the professional equipment to perform the job correctly. This is either due to the lack of finance, or the simple fact that the contractor rarely performs this type of work.

 

Pressure Washing (Explanation)

Pressure washing only cleans concrete, however; it will not eliminate oils or contaminants in concrete. It does nothing to profile or open the pores of concrete. Epoxy will not adhere to concrete for any length of time if the concrete is only cleaned. Pressure washing is unacceptable.[/vc_column_text][/vc_accordion_tab][vc_accordion_tab title=”Do you use a walk behind floor grinder or a hand grinder?”][vc_column_text]If a contractor only owns a hand grinder and does not own a professional walk behind grinder to perform epoxy coatings projects, they most likely do not do these jobs very often, and lack the experience to do these jobs properly.[/vc_column_text][/vc_accordion_tab][vc_accordion_tab title=”What MIL thickness do you install the epoxy?”][vc_column_text]Any contractor that installs epoxy floor coatings will certainly know the mil thickness in which they will install the floor coating.  If they do not know this basic information, you should find a contractor that does. Proper mil thickness is important. If the epoxy coating is too thin, the concrete will start to show through as the concrete absorbs the epoxy into its pores. More importantly, if the epoxy is too thin, you will not receive the abrasion and impact resistant floor that you paid for. Your floor coating will prematurely wear down to bare concrete in high traffic areas. You will either have to live with a worn through epoxy coating or pay to have the floor redone.[/vc_column_text][/vc_accordion_tab][vc_accordion_tab title=”What MVR (Moisture Vapor Resistance) can your epoxy block?”][vc_column_text]Moisture Vapor Resistance ratings in epoxy is the measure of “how much moisture pressure concrete may release before an epoxy coating fails”. All flooring types such as tile, wood, laminate, coatings, etc. can fail from loss of adhesion due to excessive moisture pressure in concrete. Epoxy coatings will fail by bubbling, blistering, or losing its bond (peeling off) the concrete when too much moisture is found in concrete.  Many epoxy manufactures offer different epoxy formulations. They formulate and sell standard epoxies that block up to 3lbs of MVP (Moisture Vapor Pressure) as well as Moisture Mitigation epoxies that can block up to 25 lbs. of MVP. Most epoxy installation contractors purchase and install “standard” epoxy that is rated at 3 lbs. of MVR as this formulation is less expensive than their counterparts. 3 lb. MVR epoxy however is industry standard and is acceptable in many concrete floors. It is the bare minimum in Moisture Vapor Resistance protection though.

All concrete floors contain moisture and moisture pressure. This holds true even in the driest inland environments such as deserts and valleys and are especially true in environments that have high moisture air content such as coastal areas and beaches or areas that receive heavy rain fall. Concrete acts and breathes in the same manner as a sponge. Concrete absorbs and repels moisture. When concrete expels its moisture, the moisture always travels to the warmest part of the concrete which is the surface. The surface is where your coating is installed. The moisture pressure will travel upwards were it will meet and compete with the epoxy coating. If the moisture pressure being expelled by your concrete is greater then that of your epoxy MVR rating, your epoxy coating will fail. If the MVR rating in the epoxy is greater than the pressure being expelled in the concrete, then there will be no adverse effects to the epoxy coating. In example:

Moisture Vapor PressureFound in Concrete Moisture Vapor ResistanceRating in Epoxy (MVR) Result
     
6 lbs. moisture vapor pressure      → 3 lb. MVR Rating                → FAIL
6 lbs. moisture vapor pressure      → 8 lb. MVR Rating                → PASS

 

It is extremely important your contractor know the capabilities and limitations of the epoxy they are installing.  If they do not know the MVR or Moisture Vapor Resistance of their product, they certainly should not be installing it let alone taking your money to install it. If they do not know their MVR rating, they do not know if it will fail. [/vc_column_text][/vc_accordion_tab][vc_accordion_tab title=”What type of Clear Coat will you apply to my floor?”][vc_column_text]There are four primary categories of clear coats used on epoxy floors today. These classes are Polyaspartics, Polyureas, Polyurethanes, and Epoxies. Epoxies are the least expensive of all the clear coats. Epoxy clear coats are only used in facilities that do not see sunlight or where a customer needs concrete protection only and does not care about aesthetics.  Epoxy clear coats are not U.V (Ultra-Violet) stable.  Epoxy clear coats will turn yellow or green in as little as 6 months when exposed to sun light. Stay away from Epoxy clear coats in the home. You will save a little money now and regret it later.

All the “Poly” category clear coats are U.V. Stable and are highly chemical, abrasion, and impact resistant. They will not yellow. The differences between the poly’s matters more to the contractor than they do to the customer. This is due to the different product characteristics when installing each of the poly’s. The Polyaspartic and Polyurea are very similar whereas the Polyurethane is quite different. The Polyaspartics and Polyureas are “High Build” clear coats allowing them to be installed in one coat and they also cure (dry) very quickly. The Polyurethane is a “Thin Film” clear coat that cures (dries) slowly.

The primary reasons a contractor would install a polyurethane as opposed to a Polyaspartic or a Polyurea is because it is easier to install as it offers longer working times. It is also less expensive per gallon. If a contractor chooses to use a polyurethane, they MUST install a minimum of two coats as the polyurethane is a thin film system. A clear coat must be thick enough to offer protection from abrasion and impacts as well as seal any aggregates such as paint chip or quartz in the floor. The problem with Polyurethanes is there are significant dry times in between coats (typically 12-36 hours) which means your project will take longer to complete. All the Poly’s are suitable for U.V. stability, high impact, and high abrasion protection. Generally, Polyaspartic or Polyurea are favored as they offer quicker installation and return to service times.

Many contractors install epoxy clear coats. The two primary reasons they would do this is either their lack of knowledge due to not being trained, not doing any product research, or they rarely or have never installed an epoxy floor. Equally, if not more concerning is that they realize the epoxy clear is going to turn yellow later but install it anyway to cut cost and maximize their profits. If this is the case, they understand that the epoxy clear will look excellent at the time of installation and the customer would have no way of knowing the difference.

Some contractors install a hybrid clear coat system which astonishingly is recommended by a very select few manufactures. The manufacture recommends these hybrid systems to keep flooring costs down and keep their contractors happy and coming back for more. The contractor will install a hybrid system to their customer to cut their cost and maximize their profit. This is deceptive and is wrong. This practice could be deemed acceptable if the contractor gives you the choice and price reductions of different clear coat systems. So, you are probably wondering what a hybrid clear coat system is. A hybrid system is when a contractor installs an epoxy clear coat in combination with a Polyaspartic Polyurea. Remember, the epoxy clear is much less expensive than the Poly. When sealing a paint chip aggregate or quartz aggregate floor, the aggregate will suck up most of the clear. The contractor will use the epoxy clear to seal in the aggregate knowing that the epoxy clear is not U.V. stable. They will then install the U.V. stable poly on top of the epoxy clear. By doing this, the contractor saves a considerable amount of money by coating 75% of the floor in cheaper inferior material, and 25% of the floor in expensive suitable material. This method of installation will pro-long the duration of time before your floor yellows but eventually it will yellow due to the installation of epoxy clear.[/vc_column_text][/vc_accordion_tab][vc_accordion_tab title=”What MIL thickness do you install the Clear Coat?”][vc_column_text]Any contractor that installs epoxy floor coatings will certainly know the mil thickness in which they install the clear coat.   If they do not know this basic information, you should find a contractor that does. Proper mil thickness is important. If the clear coat is too thin, you will not have the abrasion resistance and impact protection, nor the aesthetic beauty that you paid for. Your floor coating will prematurely wear down to the epoxy or the aggregate such as the paint chips or the quartz in high traffic areas. If the clear coat is applied to thin, over the years the coating can wear down to the epoxy or the aggregate and will be nearly impossible to fix. If the original clear coat has been applied to the correct mil thickness, the floor can be repaired. The reason being is although the clear coat has become thinner, there is still a clear coat that is sealing the epoxy or aggregate. This original clear coat can still be lightly sanded to achieve a proper profile for the new clear coat to be installed without doing damage to the epoxy or the aggregate.

 

If the clear coat is applied to thin in a Chip Floor System, a Quartz Floor System, or any floor coating system with an aggregate imbedded in the epoxy, the clear coat will not seal (or lock) the aggregate in as intended. Additionally, there will be areas of the floor that are dole and lack shine. The areas of the floor that are applied at the correct mil thickness will appear glossy and shiny, hence the floor will be inconsistent and appear to have wet and dry spots.

 

Alternatively, If the clear coat has been applied too thick, areas of the floor (or the entire floor) will be opaque and appear white and milky. This will reduce the color depth, brightness, clarity, vibrancy, and brilliance of the floor. Another problem of installing a clear coat to thick on an epoxy floor with aggregate is that some, or all the texture and slip resistance will be lost resulting in a very slippery floor when the floor is wet.[/vc_column_text][/vc_accordion_tab][vc_accordion_tab title=”How many pounds of paint chips or quartz will you apply to my epoxy floor?”][vc_column_text]This is another very important question for two major reasons.   All customers should know that Epoxy coatings are not U.V. (Ultra-Violet) stable.  Epoxy will turn yellow or green when it is exposed to sun light. A recommended clear coat can pro-long this color-shifting effect, however the epoxy will eventually shift colors. Enter paint chips. Vinyl Paint Chips are U.V. stable. When the epoxy base coat is completely covered with paint chips, the epoxy will never be exposed to the sun. Many contractors sprinkle very little paint chip on the floor which will not cover most of the epoxy. The primary reason contractors spread very little paint chips is because they are purchasing epoxy from a big box store such as Home Depot or a Paint store. The epoxy kits sold at these stores only come with a few pounds (about a sandwich baggie full) of paint chips.    Side note: The epoxy sold in these stores are classified as DYI (Do it Yourself) epoxy and are not even close to comparable to the physical properties, performance, and durability of epoxy used by professional contractors. A contractor that purchases paint chips from a professional supply house or a manufacturer generally purchases boxes of 50-55 lbs. of paint chip.

 

A second reason a contractor may spread very little paint chip is to cut cost. Vinyl paint chips are expensive. A contractor might be purchasing 50-55 lb. boxes of paint chips from a manufacturer or supply house, but still opts to sprinkle the chip to save money. Many contractors have knowledge that sprinkling paint chips intermittently will cause the epoxy floor to yellow out but will do so in and effort to cut costs and increase their profit margins. Other contractors sprinkle paint chips intermittently because they do not possess the knowledge to know that epoxy floors will yellow. They simply have not installed epoxy coatings before or have very little experience and have not done the proper product research.

 

  Secondly, another reason to ask how many pounds of paint chips will be applied to your floor is mostly aesthetic. When paint chips have been installed with the correct poundage or weight (there is a calculation for this) the floor will be very consistent throughout resulting in a beautiful floor that looks like a large slab of granite. When few chips are used on a floor, there will be inconsistent areas throughout. Some areas of the floor will have heavy spots, some areas light spots, and some areas will have no chips at all. 99% of contractors broadcast (or install) paint chips by hand. They grab a handful of chips and throw them up into the air allowing the chips to float softly down onto the epoxy. Sometimes the paint chip separates in the air like intended and floats to the epoxy surface, other times the paint chip clusters and does not separate in the air thus landing on the epoxy in clumps. Therefore, the floor will result in light and heavy spots throughout. Once the paint chips are thrown, they cannot be picked up. Whether the chips spreads evenly or lands in clumps, it stays that way.[/vc_column_text][/vc_accordion_tab][vc_accordion_tab title=”What profile will you grind the concrete to?”][vc_column_text]Now that we have established the correct equipment and process to use, now we must ask if the contractor understands how to grind the concrete properly to achieve the correct concrete profile in order to gain maximum epoxy adhesion. Sadly, in many cases we have seen, the contractor has the correct professional equipment yet lacks the knowledge of the concrete preparation process or ICRI standards. ICRI is short for “International Concrete Repair Institute”. ICRI is an organization that researches and develops industry wide standards Internationally for the proper procedures in concrete coatings. The ICRI trains and issues concrete coating guidelines for contractors to follow to ensure that the correct concrete preparation, concrete coating installations, the proper selection of the correct chemicals coatings, as well as several other key areas of our industry including safety and regulations are abided by. You can visit their website at www.icri.org

Many contractors do not understand what profiles concrete needs to be profiled too to achieve maximum adhesion of epoxy to the concrete. Consequently, they spend very little time Diamond Grinding the concrete. Again, we go back to anchor points. A contractor may feel that if there are enough intermittent grind marks in the surface, there will be sufficient anchor points for the epoxy to grab onto. This is not the case and again may lead to the epoxy peeling in many areas of the floor. ICRI guidelines states that a contractor should use concrete profile method CSP1 -CSP3. It is important that a contractor have knowledge of and adhere to industry guidelines to correctly profile concrete. If a contractor cannot answer or says huh? to your profile question, they probably do not understand concrete preparation very well and you should get a quote from a different contractor.[/vc_column_text][/vc_accordion_tab][vc_accordion_tab title=”Is your Dust Collector HEPA Certified?”][vc_column_text]HEPA certified dust collectors or vacuums are now California State Law. Any contractor found not to be using HEPA Dust Collectors are in violation of state law and can be severely fined by the state. HEPA stands for High Efficiency Particulate Air Filter. Its efficiency is rated at least 99.97% efficient on collecting dust particles of 0.3 microns in size. Using HEPA dust collectors simply means that there will be less dust released on the job site and into the environment thus the air anyone breathes onsite is safe and healthy to breathe. Concrete dust is classified by OSHA (Occupational Safety & Health Administration) as a “Human Lung Carcinogen”. Is this the biggest deal in the world for your coatings project? No. Your floor can be completed adequately without a contractor using a HEPA Dust Collector. Of course, there will be more concrete dust left behind on walls, doors, fixtures, rafters, and beams that you will most likely have to vacuum clean and wipe down yourself after the contractor has gone. This is a pain, but it will not affect your floor. A better question to ask yourself is why hasn’t the contractor made an investment in the professional state compliant equipment if concrete coatings is what they do for a living? This could mean the contractor does not perform many floor coatings jobs hence cannot justify purchasing new equipment. If a contractor only has a Handy-Vac type vacuum from a local hardware store, this is certainly a red flag that they rarely do any epoxy coatings jobs.[/vc_column_text][/vc_accordion_tab][/vc_accordion][/vc_column][/vc_row]
