Tile glue contains many additives, especially the functionality of tile glue. Generally speaking, cellulose ether is added to the tile binder to provide water retention and thickening functions, and latex powder is added to increase the bonding relay of tiles. The most common latex powders include vinyl acetate/vinyl ester polymer, vinyl laurate/vinyl chloride polymer, acrylic acid and other additives. The addition of latex powder can greatly increase the flexibility of tile adhesive, improve the stress and increase the flexibility.
Other additives are added to other tile adhesives with special functional requirements, such as adding wood fiber to improve the crack resistance and opening time of mortar, adding modified starch ether to improve the slip resistance of mortar, adding early strength agent to improve the strength of tile adhesive faster, and adding water repellent to reduce water absorption to provide waterproof effect.
According to powder: water = 1:0.25-0.3. Stir evenly to construct; Within the time allowed by operation, the position of ceramic tile can be adjusted, and after the adhesive is completely dried (joint filling can be carried out after about 24 hours, and heavy load should be avoided to press on the surface of ceramic tile within 24 hours of construction);

Substrate cleaning
Before painting, wipe the back of vitrified tile with a wet cloth to remove oil stains, protective agents, release agents and other substances that affect bonding on the back of tile.
Preparation of materials and tools
material
Prepare tile adhesive.
Stir the adhesive for tile back glue evenly.
Brush coating or roller coating can be used. Brush the evenly mixed adhesive on the back of the tile with a brush and roller. It is suggested to brush a layer evenly by "cross method" to avoid bottom leakage.
Stay for more than 5 hours, and after the adhesive is completely dried, the next construction process can be carried out.
