Often, installers use grout in place of caulk for these reasons: 1  The caulk may not exactly match the grout color.  Even when the caulk exactly matches the grout color when installed, it may not match six months later (caulk will age differently from the grout).
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.
