Paint a garage floor by emptying the space and providing plenty of ventilation before using an acid-based concrete cleaner to clean and etch the concrete. Apply a primer followed by the top coat. If the concrete is new, it must cure for at least 30 days before beginning the process.
- Empty the space
Move everything off the garage floor. With an empty space, you are able to complete the process in a minimal amount of time.
- Clean the floor
Sweep the floor to remove any loose debris. Open the garage door to provide ventilation, and wear eye protection when working with the acid. Apply the acid-based cleaner and etcher product using a plastic garden sprayer, following the manufacturer's directions. Rinse the floor well. Use a rubber squeegee to remove any excess water and allow the floor to dry thoroughly.
- Apply the primer
Use a brush to cut in the primer. Paint a strip about 3 inches wide around all walls. Use a paint roller to apply the primer to the bulk of the floor. Allow the primer to dry per the manufacturer's directions before proceeding.
- Apply the top coat
Repeat the cutting-in process using the top coat. Apply the remainder of the product using a roller. Apply a second coat after the first dries for a minimum of 24 hours.
