- 4). Apply the grout stain generously to the joints with a 2-inch paintbrush. You can get the stain on the tile without worrying about damage. Complete the entire area and then wait for the first coat of grout stain to dry. After about half an hour, use the paintbrush to paint on the second coat of grout stain.
- 5). Wait for the second coat of grout stain to dry. Then soak the entire tiled area with hot water. Scrub at the tiles to remove any grout stain that you have applied to the surface. You will then use a mop to get rid of the residual mess. After the floor has dried, you will see the completed look of the tile with the new grout stain.
