The editor of the building received the letter again and again~
Recently, there has been a lot of feedback from teachers
Tile adhesive adhesive is used
Why do bricks still fall?
Of course, first of all, we must ensure that the tile adhesive and adhesive used are produced by regular manufacturers, in line with various national testing standards, and the manufacturers provide quality assurance contracts.
If there is no problem with tile glue and adhesive, then the hollow drum of the tile will fall off mainly due to the following points:
1. Add and use
Tile adhesive is mixed with cement, sand, etc
Tile adhesive is a scientifically proportioned finished product, and there is no need to add other materials. If other materials are added, the proportion of the product may be damaged, the quality can not be guaranteed, and the tiling is prone to hollowing, falling off and other problems.
2: Non-standard use
Place the tile glue on the ground and stir with a shovel
It is difficult to mix the tile adhesive evenly with a shovel, and it is easy to appear flour ball, which causes the additives in it to be fully dissolved and reduces the effectiveness of the product; Stirring on the ground is easy to mix with dust, sundries, etc., and is polluted, which will affect the use effect of the product.
Three: blister use
Put the tile adhesive in a bucket and soak it in water
The construction master still uses the method of soaking cement to soak the tile adhesive, which is wrong, which will cause the tile adhesive to have no adhesive strength, and cause the tile to fall off in the later stage.
4. Timeout usage
If the use time is too long, add water and stir to use
The active ingredient of tile adhesive has undergone a chemical reaction, and adding water only changes the operating performance, which will lead to insufficient bonding strength in the later stage; Tile adhesive should be used with stirring, the use time should be controlled within 2 hours, and it should be discarded after drying.
Five: Overuse
The one-time gluing area is too large, and the surface of the glue is dry and solid
Outdoors dry, windy weather, the cloth glue scraping area is too large, the construction is too late, resulting in the surface of the dry solid and then tiling, which will cause brick drop; When tiling, the area of tile tape should be controlled within 1 square meter, and the wall should be pre-moistened in the outdoor dry climate.
Six: Thick stickers are used
The scraping is uneven and does not apply
Due to the good water retention performance of the tile adhesive and the relatively slow drying speed, the thick paste will make the tile adhesive shrink unevenly or too much stress during the drying process, resulting in the loosening between the tile adhesive and the tile. In this way, not only does it not save costs and space, but also brings great safety risks.
