can epoxy be applied over painted concrete?

Concrete is a great surface for the outdoors, but it can be a little boring if you don’t have any color in your backyard.

If you want to paint your concrete patio or deck with an epoxy coating, is that possible? Will it adhere to the existing paint? Or should you first remove the existing coatings before applying epoxy? In this post, we’ll answer all of these questions and more.

Will epoxy adhere to paint?

Epoxy is a two-part system, consisting of an epoxy resin and a hardener. The epoxy resin is the sticky part that adheres to surfaces.

The hardener helps cure it into a solid state at room temperature. Because epoxy is made up of two distinct parts, it can be applied over paint as long as both coats have cured completely (the harder or more durable coat should be applied first).

If you have just painted your concrete floor with acrylic paint and are trying to apply an epoxy coating over it, there are some things you need to consider:

  • Will there be any film of dirt or dust on my surface? If so, I’ll need to wipe down my floor before applying the epoxy coating.
  • Has my new acrylic paint job been cured yet? Epoxy will not adhere if there’s still moisture on the concrete’s surface!

Can you resurface over painted concrete?

When it comes to resurfacing your concrete, you have a few options. You can choose to apply a new layer of paint over the existing surface (or even two layers) and then apply epoxy.

This is probably the cheapest option if you want to completely change the color of your floor. If you’re happy with your current color scheme, however, there’s no reason why you can’t just lay down an epoxy coating directly overtop of it.

It’s important not to confuse “paint” with “stain.” Stains are usually water-based and don’t adhere as well as paint does—which means they won’t go on as long or last nearly as long as regularly painted surfaces do.

This also means that if you’re planning on staining instead of painting overtop of your concrete flooring (or even doing both), be sure that whatever product(s) used are compatible with each other before proceeding!

Can you paint concrete before epoxy?

You can’t paint concrete before an epoxy surface is applied to it, because paint is only a thin layer of protection. It won’t prevent cracking, protect against water damage or chemicals, or even protect against abrasion.

What kind of paint can you epoxy over?

Epoxy can be applied over any kind of paint, and concrete that has been painted. It can also be applied over concrete that has been stained or sandblasted.

How do you epoxy a painted concrete floor?

  • Clean the concrete.
  • Remove any paint that is on the floor.
  • Apply the epoxy to the floor and let it dry completely (about 24 hours).
  • Apply a top coat of epoxy to your new floor and let it dry for 24 hours before using it.

What kind of paint do you use on already painted concrete?

As you may have guessed, paint for concrete isn’t the same thing as regular paint. The two materials have different characteristics and are used in different ways.

Concrete paint is made specifically to adhere to porous surfaces like concrete and treat it with a waterproof sealant after it dries.

There are many brands of concrete paint on the market that you can use to cover your existing surface if it has been painted before or sealed with another material (like epoxy).

It’s important when choosing your brand that you get one that says “for use on previously painted surfaces,” so your new coating will stick properly!

How do you resurface concrete that has been painted?

You can resurface concrete that has been painted with epoxy. You can also resurface concrete that has been painted with polyurethane. You can also do both of these things if you’d like.

The only thing you need to be aware of is whether or not the paint is latex or solvent-based. If it’s latex, it will probably still be in good enough shape after it has been cleaned up and any old adhesives removed so that the epoxy won’t be ruined by them (you might have to remove some of the paint around door frames and windows if they are particularly thick).

However, if there are large swathes of solvent-based paint you’ll want to remove as much as possible before applying polyurethane or epoxy because those solvents could ruin your project and/or cause health problems for anyone working on it after you’re done.

What can you put over painted concrete?

There are a few different options you can choose from to resurface your painted concrete floor.

  • Epoxy coating: This is a popular choice because it’s easy to apply, dries quickly, and provides excellent wear resistance. It also has good chemical resistance and will not peel off over time like some other types of coatings. However, it may not be the best choice if your floor has been damaged by an all-out war with your pets or kids; the epoxy won’t stick as well to old paint (or old concrete).
  • Polymer-modified concrete coating: This type of coating is similar to epoxy but will stick better to surfaces that have been previously painted or sealed with another material like polyurethane. In addition, it offers superior corrosion protection on metal surfaces such as steel beams inside buildings. Keep in mind that this option costs about 20% more than an epoxy sealer but lasts longer than most other options available today — usually five years or more depending on traffic conditions within your building!
