Tile back coating adhesive is a kind of cement mortar improver specially used for pasting ceramic tiles. The use of ceramic tile back coating glue can effectively improve the bond strength between ceramic tiles and cement mortar, and reduce the occurrence of problems such as tile falling off and hollowing. Here are the detailed steps on how to properly use the tile back coating:
Prepare tools and materials: tile back coating, tiles, cement mortar, agitators, scrapers, gloves, protective glasses, etc.
Inspect the tiles: Make sure the back of the tiles is clean, free of oil and dust. If needed, you can use a damp cloth to wipe the back of the tile.
Mixing cement mortar: according to a certain ratio (such as 1:2.)5) Mix the cement and sand, add an appropriate amount of water, and stir well with a blender. Pay attention to the control of the water-cement ratio, so as not to affect the bonding strength of the mortar.
Apply tile back glue: Apply tile back glue evenly to the back of the tile, making sure every corner and edge is in place.
The amount of adhesive applied on the back of the tile should be moderate, not too much or too little.
Stirring the back coating glue of the tile and the cement mortar: put the tile coated with the back coating glue aside to dry for 5-10 minutes, wait for the back coating glue to dry slightly, put the tile into the mixed cement mortar, and apply the cement mortar to the back of the tile with a scraper to ensure that the tile is in full contact with the cement mortar.
Laying tiles: Tiles coated with cement mortar are laid on the wall or floor in a predetermined position and arrangement. Use a leather hammer to gently tap the tile so that it fits closely with the wall or floor.
Adjustment and fixing: During the tile laying process, use a level and spacer to ensure the flatness and spacing of the tiles. If necessary, you can use a tile clip to secure the tile and prevent it from moving.
Maintenance and cleaning: After the tile is laid, clean the surface of the tile with clean water in time to remove excess cement mortar. Then carry out maintenance according to the requirements, such as keeping the room ventilated, avoiding heavy objects pressing on the tiles, etc.
In short, the correct use of ceramic tile back coating glue needs to pay attention to the steps of material preparation, tile treatment, cement mortar mixing, back coating glue application, mortar application, tile laying, adjustment and fixing, and maintenance and cleaning. Following these steps can ensure the quality and longevity of the tiles.
