A waterproof barrier that keeps water is provided by tile. When water does penetrate the barrier through grout channels that are damaged or worn, it reduces the adhesive used to adhere the tile to the cement backer board behind it. The mastic that is weakened enables the tile to loosen and fall-off. Every tile which is loosened or falls off enables more water to the the area behind the cement backer board as well as the tiles. Stop the damage from spreading by changing the tile as quickly as it becomes loosened. The task needs only a fundamental understanding of building.
Inspect the region round the tile to determine whether water has soaked involving tiles and the cement backer board.
Pull free tiles in the cement backer board yourself, using care not to scratch or break them.
Place the blade of a grout observed on the very top of the grout channels â along the edges â of the tiles that border the alternative tile and cut out the grout.
Remove any adhesive sticking with the rear of the tile you pulled off the beaten track using a putty knife. Carve all grout on the edges of the tile using a utility knife off.
Spread a generous quantity of mastic onto the wall using a trowel and press the tile. Line the tile. Allow the tile mastic to dry for at least three times.
Press the grout â containing waterproof latex â in to the areas between the tiles using a grout float. Wipe excess grout in the tile using a clean, moist sponge.
Allow the grout to cure in accordance with manufacturer instructions as well as the tile to established.
