To stain a concrete floor, first clean it well, and then apply a concrete etching solution to open pores to hold the stain. Let the solution sit for 15 minutes before scrubbing the floor. Mop the etching solution up with water, and evenly apply the stain with a pump sprayer.
- Clean the concrete floor
Remove all furnishings, and sweep the floor well. Mop the floor with plain water, changing the water frequently to keep it clean.
- Apply an etching solution
Evenly spread a concrete etching solution over the floor with a push broom. Give the solution 15 minutes to soak into the floor.
- Scrub the floor with a stiff brush
Scrub the entire floor vigorously to deep clean it and help open the pores.
- Mop with water
Mop up the etching solution along with any scrubbed-up dirt. Use plain water, and change it frequently.
- Let the floor dry
Wait until the floor has completely air dried.
- Fill a pump sprayer with concrete stain
Read the stain directions for guidelines for diluting the product. Some stains are used straight, and others require the addition of water. Stir the stain well. Add the stain and any necessary water to a pump sprayer.
- Spray the floor
Start in the corner farthest from the door. Pump the handle of the sprayer to create pressure. Spray the floor evenly with the stain. Cover the floor well, but do not let the stain puddle. Allow the stain to dry completely before using the floor.
