  1. 1

    Sweep the garage floor to remove any light dust or dirt debris. Spray bleach cleaner on any stains and let it soak in for 5 minutes. Use a stiff-bristled brush to scrub the stains off.

  2. 2

    Rinse the garage floor with your garden hose and nozzle. For tough stains, use a pressure washer (you can rent one). Leave your garage door open overnight to speed the drying time.

  3. 3

    Repair any concrete cracks in the floor. Use a concrete or mortar-repair compound for smaller cracks. This comes in a tube similar to standard caulk. For larger cracks, use concrete patch materials. After repairing the cracks, allow the floor to dry thoroughly before applying your first coat of epoxy.

  4. 4

    Mix the epoxy paint according to the manufacturer's directions on the can. The paint mixture will depend on the size of the area you're covering.

  5. 5

    Apply a coat first thing in the morning after ensuring the garage floor is completely dry. Use a natural-bristle brush to cut in around the edges and corners of the garage floor. Roll on the remaining epoxy paint with solvent and water-resistant nylon rollers. A standard two-car garage floor should take under 2 hours to paint.

  6. 6

    Wait 16 to 24 hours before applying the second coat of paint. After you have completed that coat, wait another 24 hours before allowing foot traffic on the area.

  7. 7

    Keep the garage floor clean and dry while the epoxy paint is drying. After 3 to 7 days, you can resume parking and driving on the garage floor.

Tips and warnings

  • Before preparing your garage, test the concrete to ensure that it will be able to handle the epoxy paint. Use duct tape to tape a plastic bag onto the garage floor and leave it for 24 hours. Moisture under the bag after that time indicates that your concrete will not accept epoxy paint.
  • Because you are using harsh chemicals when preparing and painting your concrete, wear appropriate eye, lung and hand protection to avoid inhaling or ingesting any chemicals.
