Does the long-term rain affect the wall tiles posted outside? urgent

Have an impact. Because of rain or fog and high humidity, water droplets will reflect to the wall, and the home is relatively easy to get wet.

Don't be too dry on the tiled wall. If the wall is too dry and the water is absorbed too quickly, it is difficult for the strength of cement slurry to reach the normal level. As long as it does not affect the construction, the proper humidity of the wall is beneficial to the quality. However, after the tiles are pasted, it is best not to get wet by rain within two days, so as not to affect the cohesive force.

Precautions for wall tiling:

1. Clean the base surface before tiling.

If there are decorations such as lime putty, latex paint and wallpaper on the wall, or there is dirt on the ground, it must be cleaned up, otherwise the cement mortar will not be firmly bonded to the base;

In addition, if there are cracks in the wall itself, proper treatment should be done before sticking bricks to avoid cracking or falling off of wall bricks caused by the expansion of cracks in the grass-roots structure in the future; Also, for the ground and wall with large difference in flatness or verticality, cement mortar should be used for leveling. Compare the color difference of tiles before laying.

2, wall tile to fully soak.

Because of the high moisture content of wall tiles, this feature must be taken into account when pasting. Before tiling, the base should be fully watered and moistened, otherwise the moisture in the mortar will be quickly absorbed by the dry base and ceramic tiles, which will affect the bonding fastness. Otherwise, the wall brick will absorb water from the cement, so that the cement can not play the role of adhesive.

3. Pave the floor tiles and smooth the ground first.

Floor tiles don't need cement. After knocking flat, lay the floor tiles with cement slurry, and the diagonal positions of the four bricks are flush. And the order of laying is also particular.

Bricks stuck to the ground should be stuck from the inside out. If the ground has a slope or floor drain, pay attention to find the slope according to the drainage direction; The wall brick should be laid from bottom to top, and for the sake of beauty, the bottom brick should be attached afterwards. After the wall tiles are pasted, press the floor tiles. In addition, one wall cannot be glued to the top at a time to prevent the tiles from collapsing due to heavy weight. Don't trample on the floor tiles for a short time after laying.

4. Try to soak as many tiles as possible.

In summer, because the materials are drier than usual, it is necessary to extend the soaking time for materials such as floor tiles and ceramic tiles that need to be soaked in water to make their water close to saturation. In this way, the cement will not absorb water due to the drying of ceramic tiles, so that it will not be firmly bonded with cement, and the phenomenon of empty drum and falling off will occur, which will bring some unnecessary troubles.
