How to Stain or Paint Grout
- 1). Scrub the existing grout of all dirt and grime with grout cleaner. The colorant will not properly adhere to the grout unless it is completely clean. Allow it to dry completely.
- 2). Apply the masking tape to the edges of your tile to protect it from the grout paint or stain. This step is optional; if you have a steady hand, you can begin coloring without taping off the tiles.
- 3). Apply the grout paint or stain thinly, using the foam brush or paintbrush. Work in one small section, not more than 10 feet of tile at a time.
- 4). Allow the paint or stain to dry for the time recommended according to the manufacturer's directions. Apply a second coat if desired.
- 5). Remove the masking tape if you have used it on the tiles.
- 6). Dampen the nylon scrubbing pad and use it to remove any colorant from the tiles. If the nylon pad does not completely remove dried colorant, use a razor blade to gently scrape it off. Apply grout sealant if desired.
