Epoxy paint is a long-lasting coating that resists grease, oil and other materials that can stain your concrete garage floor. The benefits of coating your garage floor with epoxy paint is that it's much easier to clean.

Things you need

- Garden hose with spray nozzle
- Mortar-repair compound
- Epoxy paint, formulated for garage floors
- Natural-thistle paintbrush
- Nylon rollers, water-resistant
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.
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.
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.
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.
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.
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.
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.
