How to Recoat an Epoxy Floor

Epoxy coatings are used to seal concrete floors and make them more durable and easier to clean.

Epoxy coatings are ideal for concrete floors.
In a residential setting like a garage or basement, an epoxy coating can last between 5 and 10 years before it's time to apply a re-coat. But even unfinished epoxy floors should be prepared before they are re-coated: Epoxy creates a hard, slick shell that must be conditioned before another coat of epoxy can stick to it. .

Clean the floor with soap and water and rinse it well.

Scrub the surface of the epoxy floor with coarse sand paper to give the fresh coat of epoxy something to adhere to. Then sweep away any dust and wipe down the floor with denatured alcohol or mineral spirits.

Apply painter's tape to the base of the walls to protect them from the epoxy. (You'll need to remove the painter's tape before the epoxy dries completely.)

Pour the epoxy into a painting tin (mix first, according to the manufacturer's instructions, if necessary) and apply epoxy to the edges of the floor with a nylon paintbrush. Then use a roller to coat the entire floor with epoxy. Plan your route well so you do not paint yourself into a corner.

Leave the epoxy to dry overnight or for the amount of time prescribed by the manufacturer.

Apply a second coat of epoxy to the floor, following the same method as you did for the first coat.

Allow the epoxy to cure for the amount of time prescribed by its manufacturer. Even if your epoxy floor appears dry, you can damage it if you walk on it has fully cured. Depending on the epoxy, this may take between 3 days and 2 weeks.
