Getting Started
Getting started: Proper preparation of your bare concrete will ensure optimal results from Quikrete Concrete Coatings. Your concrete must be clean, dry and free of dirt, grease, oil or other contaminants before applying any coating. Concrete that has been previously sealed or that contains moisture cannot be coated. Complete the tests below to be sure your concrete will accept a coating.
Test for porosity:
To determine if your concrete is suitable for coating, conduct a porosity test by sprinkling a few beads of water onto the surface; if it soaks into the concrete, you’re ready to begin. If not, it is likely your surface has a coating, which will need to be stripped away before you apply a QUIKRETE coatings product. You can find a coating stripper at your local home improvement center. Thoroughly remove the existing coating before you begin this project, following all manufacturer instructions.
Test for moisture:
The presence of excess moisture in concrete can inhibit a coating’s ability to penetrate the surface. Do not apply this product to concrete areas with moisture coming from within the surface. You can test for moisture by taping a 2' x 2' piece of plastic wrap to the concrete using duct tape on all edges. Allow the plastic to sit for 24 hours. If water droplets appear on the underside of the plastic, or if the concrete is damp, the surface contains excess moisture and should not be painted. Moisture problems must be corrected before coating.
Make sure children and pets are away from the area when you use the product.
Prep
- Remove any debris and scrape away any surface paint spatters, caulk or gum. Sweep or vacuum the surface thoroughly.
- Clean the surface with trisodium phosphate (TSP), or comparable substitute, and rinse thoroughly with water.
- Allow surface to dry thoroughly.
Application
- Apply with a roller, brush or low pressure garden sprayer. (NOTE: If the first coat penetrates rapidly, apply second coat after 2 hours. If sealer is allowed to dry overnight, the second coat may not adhere properly.)
- Allow the product to soak for 10-15 minutes or until pores are completely sealed. wipe off surplus from surface before the sealer dries; clean up with warm soapy water
