When will my ceramic tile installation be ready to receive grout?
Most standard thin-set mortars will reach initial cure within 24 hours; however certain job conditions could affect the final cure time required. Always refer to and comply with the manufacturer’s instructions listed on the thin-set bag.
Keeping grout clean.
The secret to keeping grout clean is to ensure that all grout joints are properly sealed after tiles are installed. Your tiles will not absorb moisture through their top surface, but grout is basically colored cement, and is quite porous and absorbent. Sealing is a simple spray on – wipe off procedure that uses proprietary product. Remember that grout seal needs to be reapplied every few years to ensure the integrity of the seal. We are happy to advise you regarding grout sealing products and procedures.
What is the difference between sanded and unsanded tile grout?
Unsanded tile grout is used on ceramic tile that has been installed with a grout joint width of less than 1/8 of an inch wide and should always be used on polished natural stone products. Sanded tile grout is used on tile with a grout joint width equal to or greater than 1/8 of an inch.
How should tile/grout joints be sealed?
Tile grout joints can be sealed with a penetrating/impregnating type grout sealer. Sealing grout with these products will not change the appearance or color of the grout, and they are designed to prevent moisture from absorbing into the grout where it would otherwise leave a stain. However, sealers do not stop topical dirt buildup, which can be removed easily with a mild neutral cleaner if the grout has been sealed.
How can you tell if the grout joints need to be resealed?
If you put a few drops of water on the grout and they bead up, the sealer is OK. If the water absorbs into the grout, it is time to reseal.
