To do this well, the tiles in the home will not fall off
Many friends are complaining that the walls of kitchen and bathroom have been greatly reduced in the supermarket environment. More friends at home because of the old home age, the use of life increased, the home tiles price hollowed out. Wall surface ground floor treatment is not clean, water wetness is not enough, the dust on the back of tiles design is not removed, too much water trace before paving will lead to wall tiles and wall adhesion not tight, the use of a period of time will appear loosening and falling.
The water absorption of tiles will directly affect the firmness of the paste. According to the state regulations, the water absorption of glazed tiles is E less than 0.5%, the shrinkage and expansion rate of tile is about 4 x 10-6. When the water absorption rate of bathroom tiles or the cement does not reach the standard, the thermal expansion and shrinkage of the floor tiles will result in the separation and drop if the shrinkage ratio of cheap tiles and cement is not consistent.
During construction, if the cement mortar is too thick or too much water, the rustic tiles will fall. In addition, if the wall tiles design are large size, if the seam is too small, it will easily become warped and cracked after thermal expansion, cold contraction and mutual extrusion. The water absorption of tiles is low. If the porcelain wall tiles are not fully fitted with the cement, they are subjected to large impact force, such as stampede or hard material impact, which can easily cause the separation of tile and cement, and the bottom of the size tiles are empty.
When the paving is applied, if there is a hollowing on the edge of the large tiles, irrigation can be done on the part of the hollowing part to avoid the overall replacement. There are a small number of local empty drum in the style tiles on the wall, such as without affecting the installation of bathroom cabinet, mirror, shower head and water heater. But if the installation and daily life are affected, it is suggested that the ceramic tiles be knocked off and re laid. If 2/3 tiles appear hollowing, they need to be removed and repaved.
If the porcelain tiles which have been laid for a long time are empty, they should be opened in the middle of the wood tiles when they are dismantled, and then smashed slowly to the four sides, so as to avoid damage to the tiles around them. In the course of construction, large size tiles are encountered, before the paving, we need to do sample pieces, test the bond strength, prevent blind construction to cause large area empty drum or fall off.
The choice of the decoration in summer and autumn, it is suggested to avoid the use of early strength cement, because the cement has higher compressive strength than the ordinary type 10~24%. It will soon dry off after mixing and is very unfavorable to construction. For some complex walls, such as the surface which is too smooth or coated with waterproof layer, the surface of the wall must be batched, drawn, steel wire mesh and so on, so as to ensure the level of the wall.
The role of small tiles in life is very important. Besides visual enjoyment, cleaning is also important. Although it is impossible to avoid falling off, it can still cure the delay and repair. We must take the right medicine, so that we can deal with the problem of shedding correctly and make our home bright every day.
