Whether you use tile glue correctly (1)
It is believed that the name "ceramic tile adhesive" has been "deeply popular". Many owners or decoration masters are using ceramic tile adhesive to pave and paste ceramic tiles, but in some cases, they often encounter the following situations
[Scene 1: mixing cement with tile glue]
Some decoration companies want to save costs when laying bricks, they will add cement to the tile glue, so as to reduce the amount of tile glue and achieve the purpose of reducing costs. In fact, such "mixed use" of tile adhesive can not guarantee the effect of tile pasting, and the repair cost will be higher in the future. For consumers and owners, there are not only hidden dangers of brick dropping, but also hidden maintenance costs.
With the advantages of high bond strength, water resistance, frost resistance, aging resistance, and convenient construction, ceramic tile adhesive complying with national standards and grades has developed very mature in foreign countries. In recent years, it is gradually popularized in China and is gradually replacing cement mortar. However, we should pay attention to the construction specifications and selection standards of ceramic tile adhesive. Moreover, adding cement sand to ceramic tile adhesive will greatly affect the adhesive force and product performance of ceramic tile adhesive.
[Scene 2: cement sand is used for floor tiles, and tile glue is used for wall tiles? ]
Although the floor tiles are paved with cement sand, even if the tiles fall off, they will not hit people. But the problem is that the current specification of ceramic tiles is large and relatively thin. When cement sand is used to paste the floor tiles, the problem of edge warping and hollowing will easily occur. The sound of people walking on it is very disturbing.
In addition, some stone materials have high humidity sensitivity. The hydration in the cement sand will make the stone materials easy to form watermarks and alkali. Therefore, no matter the wall or the floor, it is recommended that you choose the appropriate tile adhesive for pasting, which is convenient and comfortable.
[Scene 3: randomly mixing tile glue]
It is often seen on the construction site that the decorator poured the powder / cement sand on the ground, added water at will and mixed it manually. But the tile glue can not be mixed on the ground like the cement mortar, because this will lead to uneven mixing, and the proportion of hand mixing and water adding is not accurate, which will lead to the loss of effective components of tile glue and the decrease of adhesive force. The correct way is to slowly pour the ceramic tile powder into the clean bucket, add the purified water according to the proportion, and use the electric mixer to mix the slurry to a uniform and non caking state.
Correct practice - the correct construction of tile adhesive should be in a clean bucket, evenly stirred with an electric mixer
