Can you epoxy a concrete basement floor?

You can epoxy coat a concrete basement floor. Epoxy is the best floor coating for a basement because it’s resistant to moisture and corrosion, allowing you to use your garage or basement as an extra living space without worrying about it getting ruined by water damage.

If you’re unsure whether you have enough time to properly prepare your concrete slab before applying epoxy, don’t worry: there are ways around this problem that make applying epoxy much more manageable.

How do you prepare a concrete basement floor for epoxy?

You’ll need to remove all oil and grease, dirt, old paint, rust, concrete slabs and mastic. Soap and water are good for removing the top layer of dust from your basement floor.

If needed use a scrub brush or steel wool to get rid of any remaining dirt that is stuck on the floor. If there’s old paint on the floors you want to remove this first before adding epoxy since it could contain lead which is toxic when ingested by children (and adults).

Remove all concrete slabs by chiseling away at them until they break into pieces small enough to fit into trash bags or put through a trash compactor if they’re too big.

Remove all concrete mastic using an electric scraper tool with a blade size that allows you access into corners without damaging surrounding surfaces as well as being able to reach underneath moldings along walls where debris tends to collect after years of use.*

Use an angle grinder equipped with a wire wheel attachment**to remove all rust from your basement floor so that it’s nice and smooth when applying epoxy.*

Can you epoxy over old concrete?

Yes, you can. In fact, epoxy coatings are more durable than regular concrete floors. Epoxying over old concrete is also called “densifying” the floor, as it makes the underlying surface much more durable and resistant to damage from moisture and other elements.

Here’s how:

  • Remove all dust from your floor before applying epoxy. This ensures that no dirt particles interfere with the adhesion of your epoxy coating later on. Also make sure there’s no oil or grease left behind by cleaning rags—you don’t want any residue on your new floor!
  • Sand down any rough edges in order to create a flat surface for painting; this will help ensure that your epoxy sticks well when applied later on (and potentially avoid accidents if anyone misses a spot). Make sure not to sand too heavily—you’re just trying to smooth out some bumps here!

How do you seal a basement floor with epoxy?

You can apply epoxy flooring to a basement floor in much the same way you would with any other kind of flooring. First, though, you’ll need to prepare your surface.

Prepare Your Surface

First, remove any dirt or debris from your concrete floor. Use a broom or shop vac to do this. You may also want to use an etching product specifically designed for concrete floors (available at most hardware stores) as an extra precaution against stains and mildew growth in the future.

This will ensure that oils don’t seep into your epoxy layer as it cures and could prevent staining if you seal the surface with another coating later on (such as polyurethane).

Can I epoxy my basement floor myself?

Yes, you can epoxy coat your basement floor yourself. The key is to be careful with the following things:

  • Epoxy resin (resin is the sticky part of epoxy)
  • Temperature and humidity. It needs to be less than 80 degrees for application and curing. Make sure you’re using a proper ventilation system if you can’t control these factors.
  • Ventilation system. You should install a ventilation system so that there’s no risk of fumes building up in an enclosed space like your basement.

Is epoxy a good idea for basement?

Yes, epoxy is a good choice for basement floors. Epoxy can be used to seal concrete and stone floors, as well as tile. It can also be used to seal other surfaces such as wood, linoleum or vinyl.

Epoxy flooring is ideal for basements because it’s impervious to moisture, making it resistant to mold growth.

In addition to being easy-to-clean and crack-resistant (meaning no unsightly seams), epoxy flooring reduces noise in the room by absorbing vibrations caused by foot traffic or other activity in the home—a plus if you’re living below another family member!

What happens if you don’t etch concrete before epoxy?

Epoxy can be a great way to add a layer of protective coating to the concrete floor in your basement, garage or any other room where you need it.

But if you don’t etch the concrete first, there’s a chance that some epoxies won’t adhere properly.

Here are five ways that not etching your concrete can impact how well your epoxy holds up:

What are the disadvantages of epoxy flooring?

  • Epoxy flooring is expensive.
  • Epoxy flooring is not easy to install, repair and clean.
  • The epoxy coating is slippery, which can lead to accidents if you have kids or pets running around your home all the time.
  • An epoxy coating will not come off easily when you decide that you don’t like it anymore and would like another color or style of flooring instead; this makes it difficult to change the look of your basement after installing an epoxy coating onto your existing concrete flooring surface


Epoxying your basement floor is a great way to protect it from moisture and prevent mold. It’s also a good idea to remove any old paint or carpet first before applying the epoxy, so that you don’t get any discoloration on your new floor once its dry.
