Getting Started
Getting started: Proper preparation of your bare concrete will ensure optimal results from Quikrete Concrete Coatings. Your concrete must be clean, dry, free of dirt, grease, oil or other contaminants before applying any coating. Concrete that has been previously sealed or 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.
- For heavy oil stains, use QUIKRETE Oil Stain Remover to absorb and lift tough, oily stains.
- Clean the surface with trisodium phosphate (TSP), or comparable substitute, and rinse thoroughly with water.
- Allow surface to dry thoroughly.
Application
Etching Stain requires a bit of patience before you see the actual, true results. When first applied, the finish may not look like you expected – but hang in there. When the stain dries, a surface residue will appear. After you remove the residue, the color may appear dull. The sealer will take your finish from dull to impressive and enhance the color. Keep in mind the color and transparency of the finish will vary depending upon your concrete’s surface and porosity.
Apply Etching Stain
- Wet the surface with water, removing any puddles.
- Apply stain using an all-plastic pump sprayer, mop or brush. Make sure to saturate the entire surface with the stain.
- Allow stain to dry a minimum 4 hours or until it is completely dry. For best results, wait 24 hours before washing off residue.
- Remove residue by washing with a solution of 4 ounces of baking soda for every gallon of water. Scrub thoroughly with a stiff bristle brush. Remove wash water with wet vacuum or mop.
- Allow surface to completely dry and then topcoat with QUIKRETE Etching Stain Sealer (exterior use) or QUIKRETE Premium Clear Epoxy Coating (interior use).
Apply 2-Part Premium Clear Epoxy
- Be sure the concrete has dried thoroughly before you apply the 2-Part Premium Clear Epoxy. Thoroughly mix Part B into Part A and let stand for 30 minutes.
Tip: For added skid resistance, add QUIKRETE Anti-Skid Additive directly into the epoxy mixture, following all instructions on the package. - Apply epoxy with roller, moving it across the concrete surface in a back and forth motion. Allow 24 hours dry time before light foot traffic and 72 hours for automobiles.
