Before you start, make sure the surface is clean. Wipe off excess oil and grease spills from the concrete surface. Scrape and sweep away dirt and loose contaminants from the surface.
Apply a thick layer of BEHR PREMIUM® Concrete & Masonry Paint Stripper to the surface by using a paint brush or bristle broom. Distribute evenly.
Most coatings take between 1-6 hours to lift. Check periodically during the waiting period to ensure that the coating is completely covered with the paint stripper. If the coated surface becomes visible again, re-apply a light coat of paint stripper. It should remain wet and active until the coating wrinkles.
Use a scraper or pressure washer to remove all coating and residue. Rinse thoroughly with water to remove all chemical residue before re-coating. Prevent all rinse solution from entering storm drains.
Clean and etch your concrete surface using BEHR PREMIUM® Concrete & Masonry Cleaner & Etcher. Use a plastic watering can to evenly distribute the product.
Spread the cleaner & etcher using a stiff bristled, non-metal brush or broom. Allow the product to remain on the surface for 10-20 minutes then scrub vigorously using the broom.
Ensure the cleaner and etcher does not dry on the surface. Lightly mist the surface with water, if needed, to keep it wet.
Thoroughly rinse the concrete surface with clean water using either a garden hose with a high-pressure nozzle or a pressure washer. Prevent all rinse solution from entering the storm drains.
The surface is ready for priming when it feels like medium-light grit sandpaper and no residue or loose concrete remains. Excess residue may interfere with the adhesion of the coating. Check for dust or powder on the surface by wiping your hands over the surface. If residue is visible on your fingers, repeat the rinsing step.
Once the surface is cleaned and etched, apply the bonding primer to enhance adhesion. Apply using a high-quality pump sprayer, 1/4 - 3/8" nap roller, nylon-polyester brush or pad applicator.
The bonding primer will dry to the touch in approximately 2 hours. Use the bonding primer when air and surface temperatures are between 50-90 degrees F. Wait at least 4 hours but before 30 days to apply the topcoat.
The surface is now ready for the topcoat.
