Step 1: Prepare Tile for Grout

Before adding grout, clean the surface of the tile and remove any spacers used when setting the tiles.

Step 2: Seal Tile to Prevent Discoloring

Completely seal the stone tiles using a natural stone sealant applied following manufacturers’ instructions; this will prevent the stone from being discolored by the grout.

Step 3: Apply Grout

Apply the grout using a grouting float. Move the float in a circular motion, making sure that grout completely fills gaps between tiles. Important: Only grout as much tile as you can clean off on a few minutes. Don’t let the grout dry on the surface of the tile or cleanup will be much more difficult and the tile can actually be damaged.

Step 4: Clean Tile

When grout has dried to a light haze, wipe the tile surface clean with a damp sponge. Be careful not to wipe grout from between the tiles.
