Project Checklist

Valspar® Etching Stain and Etching Stain Sealer

Before you begin

For optimal results, your concrete must be clean, dry and free of dirt, grease, oil or other contaminants before applying Valspar concrete coatings. Concrete that has been previously sealed or that contains excess moisture cannot be coated. To ensure your concrete is able to accept a coating, we recommend you test the surface as instructed below for moisture content and presence of obstructive sealer before beginning this project.

Test for presence of sealer

Sprinkle a few beads of water onto the surface. If they soak into the concrete, you're ready to begin. If they remain on the surface, it is likely your surface has a coating, and you must strip it away before you apply a Valspar coating. Purchase a coating stripper at your local home improvement center and follow the manufacturer's instructions to thoroughly remove the existing coating before you begin this project.

Test for excess moisture

Tape 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. You must correct the moisture problems before you begin this project or the coating will not penetrate the surface properly.



1. Remove debris and scrape off paint spatters or caulk. Sweep or vacuum thoroughly.

2. Clean the surface with trisodium phosphate (TSP) or comparable substitute, and rinse with water. Allow surface to dry completely (4-12 hours).



1. Wet the surface with water, removing any puddles.

2. Use an all-plastic pump sprayer to apply Valspar® Etching Concrete Stain in a circular motion, saturating the entire surface.

3. Let dry thoroughly — minimum 4 hours or 24 hours for best results. When the stain is dry, you will see a residue on the surface. This is normal.

4. To remove residue, use a mixture of 4 ounces of baking soda to every gallon of water and scrub with a stiff bristle brush. Rinse again with clean water, using a wet vacuum or mop. The color will appear dull—this is normal.

5. Let surface dry for 24 hours before sealing.



1. Use a roller to evenly apply Valspar® Etching Stain High Gloss Sealer. Now you will see the brilliant color come through.

2. Use one coat for low gloss and two or more coats for higher gloss.

3. Let dry 24 hours before walking on surface.
