Many people choose epoxy floor for their garages or workspaces because of its durability. It protects the concrete underneath it, while it also resists damage due to heavy objects and motor vehicles. Most epoxy flooring is also resistant to water and stains, making it ideal for the cluttered work area. Although the epoxy flooring is solid, it is also vulnerable to damage. Chemicals such as battery acid can corrode the coating, and it can also fade or begin to crack with age. Fortunately, you can repair the damaged epoxy flooring and make it look like new.

Materials needed to repair epoxy flooring

Depending on the type of problem with the epoxy coating, there are a number of different materials needed to remedy it. To repair large cracks in epoxy, many people use an electric and rough sander, strong sandpaper, such as diamond sandpaper. You can also use a heat gun or a blow dryer, with a razor blade and paint scraper to remove the damaged epoxy. A very important thing to have when repairing epoxy flooring is the new epoxy floor paint.

Repairing faded or discolored epoxy floor coating

The best way to repair discolored or faded epoxy coating is to add another layer of epoxy paint on the existing layer. Choose a color that matches the existing epoxy or a darker color. Use a paint roller to roll the epoxy paint evenly on the floor. For a thicker coating, allow the first coat to dry completely and then apply the paint again.

While painting with epoxy, be sure to ventilate the room. Open all doors and windows before opening the paint and leave open until the epoxy is completely dry. In order to preserve the color and avoid fading in the future, it is a good idea to apply a clear sealant on dry epoxy.

Repairing epoxy floor coating with an electric sander

One way to repair cracked epoxy flooring is by removing the cracked epoxy with an electric sander. Because the epoxy is very strong, a very rough, strong sandpaper is needed. Diamond Sandpaper is ideal. Clean and dry the damaged epoxy, then begin sanding at a low setting. If the epoxy does not come out, place the sander at a higher value. Be sure to wear a dust mask when sanding epoxy to prevent inhalation of epoxy dust. Once you remove the damaged epoxy, cover the area in a new layer of epoxy and let it dry. Then apply a clear sealer across the floor.
