Most tile used in moisture-prone places is waterproof, and the tile itself isn’t damaged by an inordinate amount of water. Grout and mortar, on the other hand, can deteriorate under moist conditions and demands protection or the tile may begin to lift away from the wall or ground.
Grout Isn’t Forever
Even in the bathtub or places developed to withstand moist and moist conditions, a tiled surface isn’t waterproof. The tile itself may not allow moisture to penetrate, but also the grout, or thin lines of mortar between the shingles, is susceptible to water damage. If you leave water standing on the surface, it may loosen the seal between the tile and the grout, allowing water to leak through. Moreover, you should seal grout consistently, about every six months, so that it will repel water rather than absorb it. If you do not seal the grout consistently, particularly near a bathtub or sink, it will gradually begin absorbing water.
Cracks and Gaps
Cracks from the tile, gaps in between the tile and a bead of caulk or chips from the esophagus can allow water to create its way under or behind the tiled surface. The crack does not have to be big for excessive or standing water to make substantial damage. Repair any tile, grout or strip of caulk that reveals damage or excessive wear to prevent water from making its way below the surface.
Behind It All
After Water makes its way beyond the grout or tile, it starts to do real damage, such as loosening the bonding between the tile and the flux. The mortar which holds the tile in place will begin to loosen and crumble as well as the tile will fall apart. Additionally, in the event the flux isn’t waterproof, it will swell and warp, further pushing the tile away. Mold and mildew can form, which eats away the mortar farther.
Standard maintenance and limiting water contact may prevent water damage to tile surfaces. Reseal the grout frequently, particularly on backsplashes and shower walls and floors where water contact cannot be avoided. Do not allow standing water to tile surfaces whenever possible. In scenarios where you can not avert it, remove it as soon as possible. Use a squeegee and clean cloth to wipe off puddled water. Inspect places around the borders of showers and sinks frequently and replace caulk when it becomes cracked or dry.
