However, when grout is used in place of caulk, the grout can cause structural and aesthetic problems. 1  The grout will crack allowing moisture to penetrate. 2  Where the grout is sufficiently strong, movement in the walls, floor, or countertop can damage the tile.

Grout is the material that is used to fill in around ceramic tiles. By filling the gaps, it prevents food, dirt and water from getting between the tiles. Once the grout is sealed, it's still not ready to use. Most sealers require at least 24 hours to dry before they can get wet. Some formulas may even need up to three days to dry. Homeowners always need to consult with the manufacturer's specifications to ensure the proper installation of both grout and sealer.
