Cracks in grout could become more than an annoyance if left unrepaired. A crack allows water to seep in between the tiles and compromise, over time the construction of the drywall behind them. This may lead to leaking, tiles falling off the wall or worse, structural damage to the wall studs. Hiding them signifies regrouting them when cracks in the grout exist. It is the only real way to make certain the cracked region is completely and completely mended.
Eliminate the grout that is cracked. Use a saw and cut the cracked grout off. Cut at about two-thirds of the way down to provide the new grout a base to stick to. Do this with every crack that you see.
Open a container of grout. It’s available at any hardware store. Dab a float’s corner and then push it out area to the sawed. Smooth it out as much as possible.
Wipe the region with a moist sponge. This smooth and also will remove excess grout from the wall.
Wipe the tiles. When there’s any residue buff them blank.
Seal the grout with a grout sealer. Sealers require grout drying times until they can be applied by you. Read the directions before program.
