How To Seal a Garage Floor With Epoxy

Tired of scrubbing oil off your garage floor or spreading kitty litter to soak it up? Paint epoxy on it, and you can wipe up oil in a jiffy.


  • Step 1: Put your protective wear on and mix the epoxy, letting it stand as directed on the label.
  • Step 2: Fill in cracks, holes, and mars in the floor with epoxy crack filler using a plastic putty knife. Let it dry for at least four hours.
  • Step 3: Apply the epoxy paint to the floor with a paint roller and tray. Use a paintbrush to fill in the corners. Allow it to dry, and then lay down a second coat.
  • Step 4: Apply any top coat that may have come with your epoxy. Allow 72 hours before parking a car on the new finish.
  • FACT: Did you know? One of the rarest cars in the world, a 1937 Bugatti 57S Atalante, was discovered in the garage of an English surgeon after he died in 2007. It hadn’t been used in 50 years.
  • Step 5: Rinse the floor and the broom completely and scrub the floor again before giving it a final rinse. Allow the floor to dry for at least four hours.
  • TIP: Starting in the far corner of the garage will keep you from walking on an area you have already completed.
  • Step 6: Sweep the floor thoroughly to remove dirt and debris. Use the hand brush to remove dirt from any corners.
  • Step 7: Tape the plastic sheeting on the walls, beginning at the bottom of the wall or at the height to which you will apply the epoxy.
  • TIP: To make sure the floor is spotless, stick a strip of tape to it once it’s dry. If you peel it and see any dust or particles on the sticky side of the tape, clean it again.
  • Step 8: Put on protective gloves, boots, and eyewear; and mix the etching solution into a sprayer or watering can.
  • Step 9: Hose down the garage with water and spray the etching solution, starting with a 10 foot by 10 foot area, in the corner of the garage. Scrub the area with the hard-bristled broom, first in one direction, and then in a perpendicular direction.
  • Step 10: Tape a plastic bag to the floor for 24 hours, and then check underneath it. If you see condensation, don’t coat the floor with epoxy; it won't take to a moist floor.
