can I epoxy over painted concrete?

Epoxy is a great material that can be used for concrete, metal, wood and more. Epoxy is a two-part resin that cures to form an extremely strong bond.

It comes in a variety of colors, so you can use it to create unique designs on your concrete surface. You can use epoxy over paint or concrete and there are many different types of epoxies available! In this article we will cover:

Can epoxy be applied over painted concrete?

Yes, it is possible to apply epoxy over painted concrete. Epoxies are great for sealing and protecting any type of flooring.

Epoxies are available in a wide range of formulas that can be used on many different types of surfaces, including concrete that has been painted with latex paints or oil-based paints. The key is choosing the right formula for your particular project.

Can you put epoxy resin over paint?

Epoxy resin is a two part system. The epoxy resin and the hardener are mixed together to create the epoxy material.

Epoxy can be applied successfully over painted concrete floors, but it’s important to use a quality epoxy product and avoid using cheap materials that won’t bond well with the floor surface.

Epoxies will not bond as well to unsealed or unpainted concrete surfaces, so if you want your project to look good for years, it’s best practice to seal your concrete floors before applying any type of coating such as paint or varnish onto them.

Will epoxy stick to painted surfaces?

The answer to this question is yes, epoxy will stick to painted surfaces. In fact, it can stick to almost any surface. Epoxy is a polymer (a polymer is a substance formed by the linking of many smaller molecules) and the chemical makeup of epoxies makes them highly versatile.

Epoxies do not adhere well to certain materials like silicone or aluminum but they are very good at sticking to other materials such as concrete and wood.

There are some exceptions though:

  • You should avoid using an oil-based primer or paint on your concrete floor because oils in paints can cause the adhesion properties of an epoxy coating to degrade over time.

Other than that there aren’t any problems with painting over epoxy with another coat of paint right away! Just make sure you use solvent based acrylic paints which are compatible with polyester resins like those used in our products like [this brand].

Can you resurface over painted concrete?

Yes, you can resurface over painted concrete! You’ll be able to resurface over sealed paint and even bare concrete.

If you’re looking to re-paint the surface, we recommend using our Epoxy Resurfacer or Epoxy Overlay products. You may still want to take some precautions before applying these products.

One thing that can help is to remove any loose paint or stains from the surface with an etching primer like our Concrete Etch & Sealer product.

Do you need to remove paint from concrete before repainting?

It is important to remove the old paint before you epoxy over it. If you do not remove all of the old paint, then your epoxy will not adhere well and may come loose.

To remove paint from concrete, try using acetone or chemical strippers that are designed for removing paint from wood surfaces.

You can also use an orbital sander with 120-grit sandpaper in order to rough up the surface so that it will accept adhesives better.

If these methods do not work for your project, you can purchase a scraper specifically designed for this purpose (such as an electric floor scraper).

Can you pour resin over paint?

Removing paint from concrete is a fairly straightforward matter. You can use a pressure washer, or chemical stripper, and then scrape the surface clean to remove the paint.

Since you will be resurfacing the existing concrete with resin or epoxy, using nothing more than a sharp scraper will likely suffice.

Removing old paint before pouring resin or epoxy over your existing concrete is much easier than removing it after you pour them on top of it because there are fewer steps involved in this process.

However, if you have already poured resin or epoxy on top of your existing concrete flooring and now want to remove all traces of that layer for some reason—say that it didn’t come out exactly how you wanted—then follow these instructions closely:

What does epoxy not stick to?

Epoxy is a powerful adhesive that bonds to many different materials, but there are a few things it simply will not stick to.

  • Epoxy won’t stick to plastic. The polymers in epoxy are not compatible with the polymers used in most plastics.
  • Epoxy won’t stick to silicone. Silicone is used as an ingredient in some epoxies and paints, so if your project involves mixing the two together, they’ll repel each other when they’re dry.
  • Epoxy won’t stick to wax or Teflon surfaces very well either—they both have nonstick properties that make them hard for adhesives like epoxies to adhere too (it’s worth noting that silicone also has this property).
  • If you want something really sturdy and secure after using epoxy on painted concrete, try using a primer for extra adhesion first!

Can you pour epoxy over oil based paint?

No, you cannot pour epoxy over oil based paint. You will need to sand the old paint off. You can use a chemical stripper to remove the paint if it’s not too thick.

If you do use a chemical stripper, be sure to ventilate your space and wear gloves and eye protection.


It’s a good idea to remove any oil-based paint from the surface before applying epoxy. If you don’t want to take the time or effort required for this step in your project, then we recommend using an epoxy primer instead of plain resin.
