What is the proportion of cement binders to wall tiles?
The cement mortar and ceramic tile binder is not mixed with each other, the ingredients of the special adhesive tiles already containing cement, its composition is the proportion has been prepared, if adding cement, may make the mortar hardening strength caused by high tile cracking, if adding sand, it will reduce the strength of cement mortar, lead the poor quality of ceramic tile adhesive.
Traditional paving method: the ratio of cement to sand 1:2.5 is dried and mixed with water and then used as adhesive. Compared with the traditional thin paste method, paving method for leveling less on the wall finish process, wall napping can start tiling. The quality of traditional paving materials is difficult to control, and the quality of cement, sand thickness and mud content are difficult to control. In the matching process of cement mortar, the ratio is reasonable, the amount of material is in place, whether the uniform mixing will affect the quality of cement mortar, plastering and tiling lead to quality problems. When the operation, the worker's technical requirements are higher, although the cost is lower, but the construction speed is slower.
Pasting process: tile tiling using ceramic tile binder as main adhesive material. In the process, the wall should be leveled first; the ceramic tile adhesive instead of the traditional cement mortar is used as the adhesive between the wall and the ceramic tile. Thin paste method material is tile adhesive, can be used directly against the water quality standard, easy to control, high bonding strength. The operation of the workers is convenient and the efficiency of paving bricks is greatly improved. But the thin paste method needs to make brick walls, some more than the process of cement mortar, although ceramic tile adhesive seemingly more expensive than the cement, sand, but less than the traditional construction speed, paving, about 20% to the overall cost.
