Frequently asked questions  

1.  Does the concrete need to be cleaned before applying Epoxydoc epoxy?
Yes.   The concrete needs to be completely clean before applying any coatings.   We provide detailed instruction on prepping your concrete.
2.  How long does it take to apply the Epoxydoc epoxy?
Approximately 2 to 3 hours for a 2 car garage.  Allow 24 hr dry time before applying any sealers.    High humidity can take longer for products to dry.   Temperature and other conditions may determine overall time.
3.  If my concrete is new do I need to prepare the surface before coating?
Yes.  Concrete prep is essential for proper bonding.  We have detailed training under "concrete prep" on the home page. 
4.  How many days do I need to wait before applying any coatings to new concrete?
30 days.   New concrete needs to cure before applying any coatings.
5.  Can I apply Epoxydoc epoxy over old coatings and epoxies?
Epoxydoc can be applied over existing paints/coatings.    You must make sure that all areas are sanded with an 80 to 100 grit sand paper.   Floor machines can be rented at home depot or other rental shops, along with sand paper.   Any loose paints/coatings must be removed completely with diamond grinding or other means.   All coatings are only as good as the surface it bonds to.  If you have any questions please feel free to contact us. 
6.  What are the best temperatures to apply Epoxydoc epoxy?
Between 45 and 95 degrees.
7.  How long does Epoxydoc epoxy take to dry?
24 hours.  However depending on climate it could be a little longer.  Wait between 2 to 3 days before driving on your new coating.  This allows for the epoxy to cure properly. 
8.  If dust and particulates on the floor cause fisheye problems while applying the epoxy, what can I do?
First thing is to always make sure the floor is completely clean.  This can be done by taking a leaf blower and blowing the garage or area to be coated carefully and complete.  Make sure that all dust is removed.  If you do have a few problems while coating the floor.  Take your roller and re-roll those areas
9.  If bubbles begin to show up during  application of the epoxy what can be done?  
Take a leaf blower and blow over the surface to relieve tension in the surface.  This will pop the bubbles.  Sometimes bubbles may appear because of out gassing.  Make sure you pop all bubbles by using your leaf blower.   When you throw paints chips on top of the epoxy for your finish this will help to hide all imperfections.  This is what professionals do to add decorative qualities and hide any imperfections in the finish.  However watch your epoxy finish and check it as you go.  You do not want any bubble to form.  When it drys it will look like small moon craters.  For a smooth finish make sure all bubbles are popped. 
10.  What are the decorative paint chips for?
Paint chips provide for a decorative finish.  They also help to provide a slip resistant surface and to hide imperfections in your concrete and finish.   This will amaze you as it the secret of professional installers to make the floor look complete.
11.  Can the floor get slippery when it gets wet or has oil on it?
Yes.   The floor is a smooth surface so water and oil can cause it to become slippery.   We recommend using our nonskid additive to give the finish a nonskid surface.  If you are worried about it definitely use it.   Simply add the non skid to your finsih sealer or right into the epoxy.
12.  What is the most important thing professional installers do to insure a perfect job
The most important thing is surface prep.  The concrete must be clean and free of dust and oil.  Our cleaning solution will help clean the surface.  The best way to clean the surface is using a power washer in conjunction with the cleaning solution.   These days many people have power washers.  If you do not have one you can go to a rental store or a home depot and rent a power washer.  We recommend 2500 psi or higher.  The rental price is inexpensive for a 4 hour rate.   The power washer gets tough dirt out that is deep in the pores of the concrete.  This is simple to do and assures a more perfect bond.  After washing the concrete let it dry for several hours even 24 hrs.  We have a video showing just how this is done.  See our video instructions under the videos tab.
13.  Does the nonskid product you put on the floor make it harder to clean?
Not generally.  Rinsing using a broom or scrubber is the best way to clean.   You can use a  Squeegee to push the water out.  Using a mild detergent will help loosen oil or other dirt that has accumilated.
14.  Will the nonskid product eventually wear off?  Can you reapply it again?
Yes but it will last for many years.  If you need to add more later or reapply you can do so by adding it to your clear sealer and apply it that way.  Urethane top coats are a great way to seal your floor.   They provide a touch hard surface.  They dry thin and you can mix the nonskid additive into your urethane sealer
15.  Should I patch large holes and spalls in the concrete before beginning?
Yes.  Often times in areas of the garage concrete has broken out or loose concrete is present.   This must be cleaned out and all loose material taken out.   Using our mortar mix material you can patch the floor and make it smooth again.  This often happens at the beginning of the garage where water can puddle and freeze thaw takes place.  This effect can make the concrete break apart and spall.  Any holes deeper than ¼ inch should be patched first before applying the epoxy.  We show you how to do this in our video instruction page under How to fix damaged concrete using our mortar patch.  You can also call us to help you with questions you may have.
16.  Do I need to worry about small shallow imperfections in the concrete?
No., Small shallow holes and imperfections will fill in nicely when you use the 100% solids epoxy.  It self levels so you barely notice it.   Also when you apply the decorative chips you will cover up imperfections making it hard to notice them.  If however you want to make sure that your floor will be perfect you can apply the Epoxydoc crack filler to small holes and cracks.   The product is inexpensive and a great way to fill in any imperfections.  Remember floor prep is everything.   Starting from a nice, smooth, and clean surface yields better results and makes your job easier.
17.  Do I need to patch cracks before applying the epoxy?
Yes. Cracks are there because the concrete moves and expands all the time.  Even though there are expansion joints, concrete will relieve pressure where it needs to.  These cracks need to be filled in with our crack paste material.  It is easy to do and goes fast.   You can see how to do this in our video training section under crack repairs.   Because cracks are open you need to close them off to prevent the epoxy from running down into the crack.  Since you are using a 100% solid epoxy self leveling product, it is important to seal off any voids that might run deep. 
18.  Can cracks reappear after repairs are made and epoxy is applied.
Maybe yes and maybe no.  Concrete moves when it wants to and depending on how much movement there is will determine if the crack returns.  Generally small cracks do not reappear. While larger ones might.   The good news is that our repair products are designed to repair cracks and keep them from reappearing.   Remember however there are no guarantees with cracks.  If a crack does come back it will usually appear as a hairline crack.  The decorative chips you put on the floor are there to hide most imperfections so your floor still looks great.
19.  Does the concrete need to be cleaned up before using the cleaning solution?
Yes.   Oil and dust and dirt should be cleaned out.  This is best done using a power washer.  You can rent these at any rental store.  We suggest a 2500 to 4000 psi power washer to get the dirt out of the pores of the concrete.  This will assure a much better bond between epoxy and concrete.   First scrape out any loose oil that has built up.   Sweep the floor.    Next you will use the clean prep solution to prepare the concrete.   Move the cleaning product around by using a broom to scrub the concrete.   Last power wash your concrete carefully.   Please see our training video on proper prep of the concrete before applying epoxy.   You can view this by clicking on the video section
20.  Can I add thinner to the coating when mixing the epoxy?
You can add up to 5% thinner using MEK or xylene. This will help in making the product easier to use and to reduce any potential bubbles from forming during application.  Remember it is not necessary but it can be good to have a gallon on hand if you decide to thin the epoxy and for clean up  .If you have any questions you can email us, call us or view our video instructions.
21.  If I have had fiberglass added to my concrete will Epoxydoc epoxy cover the hairs that are present after floor prep

Yes. First  use a propane torch to torch the hairs from the floor before coating.  Coat the floor with a first coat of Epoxydoc epoxy, wait 24 hours and sand vigorously with an industrial sander using 80 grit sandpaper.   You can rent this from a rental store or home depot.  The cost to rent a machine is inexpensive.  Apply a second coat of epoxy and flake the floor.   Remember decorative chips are important to hiding imperfections in the floor. You can order more epoxy and chips as needed.

22.  Why should I use Epoxydoc over other brands of epoxy?

Epoxydoc epoxies are manufactured to the highest standards.  They are 100% solids epoxy.  Self leveling and engineered for easy application.  There simply is no finer epoxy on the market.  With over 25 years of combined experience in the manufacturing and application of epoxies and other coatings, you can be assured of a quality product.  Remember we were installers first before we became manufacturers.  We're pretty good at what we do.  Our products are used by professionals and those of you that want to do it yourself.    Epoxydoc epoxies were made with the end user in mind,  its hard to screw it up.

23.  What does 100% solids epoxy mean?

This is the finest epoxy you can buy in terms of thickness, durability, and performance.  100% solids means that when you apply 10 mils of 100 % solids epoxy it has a dry film of 10 mils.  In comparison if you use a water base epoxy which is 50% solids and you apply it at 6 mils you will get a dry film of 3 mils.  Our Epoxydoc 100 % solids epoxy is used in garages and heavy duty industrial warehouses.
