The first mistake is to put the tile glue in the bucket and use it for bubbling. The master used to be used in the method of foaming cement, which could easily lead to no strength of the tile adhesive, falling powder and falling bricks.

Mistake 2: Tile adhesive is mixed with cement, sand, etc. This will completely change the product ratio, product quality can not be guaranteed, tiling bricks can easily empty bricks.

Error 3, put the tile adhesive on the ground and stir it with a spade. Stir with iron can not be even, the effective chemical composition of the morning paint tile adhesive inside loss; the proportion of manual mixing water is difficult to accurately change the material ratio, resulting in decreased adhesion.

Mistake four, the base sand, oil, mold release agent or empty drums and other defects, untreated directly paste the tiles. The low strength of the grass-roots level and the presence of oil will directly affect the adhesive force of tile adhesives, leading to hollowing out bricks; bricks that do not meet the requirements should be processed and then re-tapped.

Error 5: It takes too long to use and stir it with water. The active ingredients of the tile adhesive have chemical reactions. Adding water will only change the operation performance, which will lead to insufficient bonding strength in the later period. The tile adhesive should be used with stirring, use time is controlled within 2 hours, and it should be discarded after drying.

Mistake six, point process construction, and do not knead the tiles. Hollowing the corners of the tiles, long-term wet conditions will result in the loss of bricks; Tiles do not knead, glue bond is not strong; Tile adhesive should be thin paste method construction, according to the grass roots flatness and tile size to determine the appropriate tooth scraping Plates should be kneaded in place when pasted and randomly checked for backfill rate.

Error 7, the cloth area is too large, the surface of the glue is dry. Outdoor drying, windy weather, cloth adhesive scraping area is too large, morning tile adhesive construction too late to cause the surface layer solid and then tiling will cause off the brick; tile tiles adhesive area should be controlled within 1 square meters, outdoor drying The climate should pre-wet the walls.
