Causes and treatment methods of cracks in living room floor tiles

Floor tiles are one of the essential decoration materials, especially in kitchens and bathrooms, which are more suitable for laying floor tiles. However, if the floor tiles are used for a long time, they will be cracked at home, which will affect the appearance. Then let's introduce the causes of cracks in the living room floor tiles and how to deal with them.

When sticking the floor tile, leave no seam or the seam is too small.

Because the coefficient of thermal expansion and cold contraction of floor tiles is small, when thermal expansion and cold contraction occur, if the joints are insufficient, the base will expand when thermal expansion and cold contraction occur, while the floor tiles will expand too slowly and easily crack.

There is no soaking or insufficient soaking before tiling.

If there is not enough soaking water before the floor tile is laid, the water in the cement mortar will be absorbed after the tile is laid, leading to cracking. Cracks in floor tiles caused by insufficient soaking water generally appear shortly after the tiles are laid.

Hand-cut floor tiles will produce dark cracks.

When cutting floor tiles by hand, due to improper operation, the floor tiles will crack, which is not easy to be found. However, after a period of time, the shrinkage of cement and temperature changes will accelerate the cracking and make the cracks obvious.

Improper composition of cement mortar

If the cement label is too large, the cement mortar will absorb water when it condenses, and too much water will be absorbed in the floor tiles after paving, which will lead to cracking of the floor tiles.

Filling sealant

When filling the caulking material, clean up the impurities in the gap with a rag, stick masking paper on both sides of the gap, then put the caulking material into a glue gun, evenly drive the caulking material into the gap, block the nozzle with a wedge, and immediately scrape the caulking material flat with a small scraper, so that the overflowing materials on both sides of the brick gap can be wiped off with a wet sponge.

Toothpaste smoothes cracks.

You can spread toothpaste evenly on the gap, wipe off the excess toothpaste around, and the surface of the floor tile will recover after the toothpaste dries.
