Can You Spray Paint Stepping Stones. Align the plastic stepping-stone mold in one corner of the concrete patio or walkway. Mix bleach with water at a 110 ratio.
Grab your favorite spray paint colors and spray the tops of the stones. You can buy the acrylic patio paint for decorating the stepping stone made of concrete wood or even terra cotta. Use a damp cloth to wipe any dirt or dust from your stepping stone then dry it off.
Repeat steps 6-7 two more times.
Let the surface dry for a few minutes. Be sure to use a stencil adhesive to attach the stencil to the stone or paint may bleed underneath. The stepping stones just needed one coat of spray paint. Take your concrete stepping stone and stencil outside or to a well ventilated area.
