Once tiles are laid and the adhesive has set, the next step is grouting. Choose a grout type based on the location and type of tiles; sanded grout is typically used for larger joints and unsanded for narrower ones. Mix the grout to a paste-like consistency and apply it using a grout float, working it into the spaces between tiles. Wipe off any excess with a damp sponge, being careful not to pull grout out of the joints.
Sealing the tiles is an essential final step, particularly for natural stone or porous tiles. The sealant protects the tiles from staining and water damage. Apply the sealant according to the manufacturer’s instructions and allow it to dry completely.
The curing time for grout and sealant varies but is generally around 24 to 48 hours. During this time, avoid walking on the floor or wetting the tiles. Proper curing is crucial for the durability and maintenance of the tile installation.
