How do you install epoxy on concrete floor?

Epoxy flooring is a great option for many rooms in your home, including basements and garages. It’s durable and can withstand heavy traffic, which makes it perfect for high-traffic areas like these. The only downside to epoxy flooring is that it’s not very forgiving when it comes to mistakes or errors in the application process.

If you don’t get the application right, there’s no way to correct it without removing the entire layer of epoxy from your concrete slab (which will cost you quite a bit of money).

To help ensure that you get your epoxy flooring job done right—and avoid having to go through all this trouble—we’ve created this step-by-step guide on how exactly how to apply epoxy coating on concrete floors in your basement or garage.

Can you put an epoxy floor over concrete?

You can use epoxy to coat your concrete floor. However, there are a few things you should be aware of before you start working on this project.

First, make sure that the concrete is clean and dry. If there is any moisture underneath the surface of your floor, it will seep through and create bubbles in your coating material when it cures.

If you see evidence of water damage or mold growth on your concrete, it may be too damaged to safely seal with epoxy.

Next, make sure that you have a smooth surface before applying any kind of finish to it: if there are cracks in your concrete that have been filled with grout or another substance—or if there are patches where troweled-on mixtures were applied unevenly—these irregularities will show through any coating material that’s applied over them; so make sure they’re filled out evenly before applying anything else (and keep in mind that this also applies to stripping old paint). And finally: do not use a floor leveling compound!

These products contain chemicals that can harm the protective layer on top of new epoxies; they’re fine for staining old floors but shouldn’t touch freshly sealed ones at all

Can you epoxy over old concrete?

Yes, it is possible to epoxy over old concrete. As long as the surface of the concrete is in good condition—with no cracks or damage—epoxy can be applied directly over the existing flooring. However, if there are any irregularities on your concrete surface (i.e., very porous) you may want to consider resurfacing it with a patching compound first. This can be done prior to applying epoxy, but it’s not strictly necessary because most epoxies will adhere well even on uneven surfaces.

If you have previously applied an epoxy coating onto your floor and there are cracks or other signs of damage in that coating now, then no: you cannot simply apply another layer over top of this damaged coat without first repairing those imperfections.

You might need to take off all previous coats down through whatever type they were (polyurethane or polyurea) until all that remains are clean bare slabs with no markings left behind by previous layers.[3]

You also cannot apply new coats if they’re cracked or otherwise damaged; however, if there are only scratches present then these don’t pose much threat unless they’re deep enough for moisture seeps into them which could cause problems later down the road when curing occurs because water expands when frozen which increases pressure on surrounding materials causing stress fractures/damage like cracking along lines where these lines intersect each other when subjected enough pressure over time due again which causes further weakening until eventually, something gives way under enough stress causing catastrophic failure at some point during curing process resulting in the total loss (no insurance coverage).

Do I need to seal concrete before epoxy?

Yes, you should seal concrete before applying epoxy.

If you don’t seal the concrete first, your epoxy will not adhere properly and you will end up with bubbling issues.

To ensure proper adhesion, use a concrete sealer that is designed for use on basement floors. The best time to apply this type of sealer is after the floor has been cleaned and dried thoroughly.

You can also purchase an acrylic floor finish in lieu of a special basement flooring sealer; however, it is important that any moisture be removed prior to application so as not to hinder the bonding process between your epoxy resin and your existing concrete surface

How long does concrete need to cure before epoxy coating?

It is important to know that it takes 28 days for concrete to cure. This is an extremely important step as the epoxy coating will bond with the new concrete and not remain on top of it. Therefore, you should wait at least 28 days before trying to do anything with your newly poured floor.

If you have already poured your floor, but are having trouble waiting the full 28 days before applying epoxy, here are some things that may help:

  • Try keeping fans on near where you’ll be working so that they blow warm air across the surface of your concrete and speed up its curing process.
  • If possible, apply a thin layer of oil or grease over any dirt or mud stains in order to prevent them from affecting how well your coating sticks (although this method isn’t guaranteed).

How do you apply epoxy to concrete?

Now that you’ve got your epoxy, it’s time to put it on. The first step is to mix the two parts of the epoxy together. Make sure you’re using a clean paintbrush and mixing thoroughly until there are no streaks in the mixture.

Next, add coloring flakes or liquid dye if desired.

Now it’s time to apply your freshly mixed epoxy onto your concrete floor! You can use a paintbrush or roller for this process—just make sure that whichever tool you choose is clean before applying any material with it so as not to contaminate your project area with dirt or other unwanted contaminants like dust particles which could negatively affect adhesion between layers downstream (more on this later).

How do you prep an old concrete floor for epoxy?

To prep an old concrete floor for epoxy, you’ll want to remove any old paint, oil, or stains. This is important because the sealant that will go over it will not adhere properly if there are any oils present.

If your floors have been sealed with a polyurethane or similar coating, you’ll need to remove this prior to applying the new epoxy coating. If your floors have been sealed with a clear-coat acrylic sealer such as a water-based polyurethane latex sealer, you can simply wash the surface and let it dry completely before applying the new epoxy floor coating.

Repair cracks and holes in the concrete before applying your new topcoat of epoxy finish by using auto body filler. Once filled in, sand smooth then clean again before priming and painting over with an appropriate primer product (such as Rust-Oleum Epoxy Guard).

Can you do epoxy flooring yourself?

  • Pros: You’ll save money by doing it yourself, and you can learn a new skill that could come in handy at home or on the job.
  • Cons: You’ll need to take the time to do it right. Make sure you thoroughly prep the flooring surface with appropriate sanding and cleaning before applying any epoxy product, as this will help prevent bubbles after application.

Is epoxy flooring cheaper than tile?

Since epoxy flooring is a new technology, the price of it varies depending on where you purchase it and how much of it you need. You can spend anywhere from $2 to $10 per square foot, depending on the size of your area and what you want your floor to look like.

If you DIY this project yourself and buy epoxy in small containers at hardware stores or home improvements stores like Home Depot or Lowe’s (which sell both residential and commercial products), then yes—epoxy floors can be cheaper than tile options.

However, if you hire a contractor who already has all their materials stocked up on-site at their office/warehouse location, then that could add costs to what may have seemed like an affordable option beforehand!


Epoxy is a great choice for concrete floors. It is not hard to install, but it can be expensive and you should hire professionals to do the work.

Epoxy is durable and long-lasting, so it will be worth the investment if you want your floor to last as long as possible!
