Step 10 · Grout and Seal
Remove the tile spacers. Mix your grout according to the package directions. Apply the grout diagonally across the tile joints using a grout float, pressing it firmly into the gaps. After about 15-30 minutes, use a damp grout sponge to wipe the excess grout off the tile surface. Let the grout cure for the manufacturer-recommended time (typically 24-72 hours). Once cured, apply a grout sealer to the new grout lines to protect them from moisture and staining. Finally, apply a bead of 100% silicone caulk around the perimeter of the new escutcheon plate where it will meet the tile.
