 Make your garage inviting by adding a pop of color with epoxy floor coating.

Do you want to give your garage floor a finishing touch? Every time you come home, a colorful, lustrous epoxy floor finish will make you—and your car—feel like you're driving into a showroom.

Epoxy Floor Coating

Epoxy garage floor coating is sometimes sold in kits that include the two-part epoxy, etching solution, decorative colored chips, and detailed instructions. Some kits also include a link to online instructions. Many coatings are grey, while others are brown or off-white, thus color options are limited. Examine the kit's contents to determine which extra supplies are required.


  • Tape plastic sheeting to the walls along the foundation's edge or at the height you'll apply the epoxy up the walls, using painter's tape.
  • To eliminate dirt and dust from the floor, sweep it well. Dust the corners and seams with an old paintbrush.

Etch the Garage Floor

  • For new or bare concrete, use the following formula: In a plastic, watering can mix the etching solution with water according to the manufacturer's instructions.
  • When working with chemicals, always be sure to use protective gloves, rubber boots, and safety eyewear.
  • Using a garden hose, wet the floor.
  • Fill a 10-by-10-foot area in the corner farthest from your exit point with the solution.
  • Scrub the area in one direction with a bristle broom, then go over it again in a perpendicular direction.
  • Continue etching little portions of the floor. After you've completed the garage, rinse the floor with a garden hose, starting in one corner and working your way forward.
  • Rinsing should be continued until the water is completely clear.

Mix the Epoxy

  • Two-part epoxy is made up of a catalyst (or hardener) and a resin (or "paint") that must be mixed together immediately before use. 
  • Swirl the paint for a few seconds before pouring in the catalyst and continuing to stir. Stir for a few minutes after the catalyst bottle has been emptied until the two components are fully mixed.
  • Replace the cover on the mixture and set aside for the amount of time the manufacturer specifies, which will vary depending on the temperature. 
  • If you're going to use decorative color chips, leave them out of the mix.

Apply the Epoxy

  • Begin applying the coating as soon as the epoxy mixture is complete.
  • You will have no more than two hours to apply the epoxy, and you will have even less time if it is hot outside. 
  • During the application and initial curing, keep the garage well-ventilated.
  • Cut in along the edges with a 3-inch paintbrush, then spread epoxy on the floor with a 9-inch roller with a 1/2-inch nap roller cover. 
  • Work in sections of 10 x 10 feet. If you have a helper to handle the cut-in work, this job will go much faster. 
  • Maintain a wet edge by rolling over previously applied epoxy edges, making sure to roll an even coating.
  • Allow 24 hours for foot traffic to dry and up to 72 hours for cars to dry before parking—longer in humid or cold conditions.
