Possible misunderstandings during the use of tile adhesive.

Myth 1: Tile adhesive is just glue.

Just hearing the name – tile adhesive, many people may think it is just cement plus glue. In fact, tile adhesive is not glue, its main component is still cement. It is formulated from high-quality cement, graded quartz sand and a variety of polymers. It is a safe and environmentally friendly product and does not contain formaldehyde, benzene and other harmful substances.

Misunderstanding 2: Mixing cement into tile glue.

This operation seems to increase the weight of materials and gain advantages, but in fact it causes huge losses. The reason is that tile adhesive relies on the intermolecular force generated by special additives in the product to firmly adhere the tiles. Adding cement at will will change the formula of the product, reduce the bonding force, and cannot guarantee the quality of the product.

Misunderstanding 3: If used for too long, add new glue and mix before use.

Some masters will mix the tile glue left last night with water and tile glue powder the next morning. In fact, the active ingredients of the tile adhesive have undergone chemical reactions. Adding water will only change the operating performance, which will lead to insufficient bonding strength in the later period. Tile adhesive should be stirred and used, and the use time should be controlled within 2 hours. It should be discarded after drying.

Misunderstanding 4: The disposable squeegee area is too large.

In dry and windy weather outdoors, the area to be scraped with adhesive tape is too large, and the surface layer is not allowed to dry in time before laying the tiles, which may cause the bricks to fall off. Use a toothed scraper to evenly scrape the glue onto the work surface. Each application should be within about 1 square meter. In dry outdoor weather, the wall surface should be pre-moistened.

Misunderstanding 5: Directly pasting ceramic tiles without leveling.

Due to the low strength of the base layer and the presence of oil, it will directly affect the adhesion of the ceramic tile adhesive, causing hollowing and falling of bricks. The wall surface is not strong and the base surface is prone to delamination and falling off. The wall is uneven and the defects are so large that the contact between the tiles and the wall is not in place, which can easily cause hollowing.
Misunderstanding 6: Use tile glue to fill gaps.
Tile adhesive and grout are both building material auxiliary materials, but tile adhesive can only be used to stick to the back of tiles. If you use tile glue to fill the joints, it will just block the shrinkage joints of the floor tiles. This causes the floor tiles to bulge due to heat and are prone to hollowing and falling off. Therefore, special caulking or caulking agents should be used for caulking.
