tile adhesive . As a tiling artifact in modern laying systems, ceramic tile adhesive is becoming more and more widely used. However, some new masters still have many questions in actual construction. For example, apply ceramic tile adhesive on both the walls and the backs of the tiles. Will the tiles be more solid? Let’s take a look at the principle of

backing :

tile backing glue, it is a interface agent specially used on the back of tile. By changing the interface characteristics of the ceramic tile, the bonding between the ceramic tile and the ceramic tile glue (or cement mortar ) is improved, and the hollowing and falling of the ceramic tile is reduced.

tile back glue is polymerized from low-particle size acrylic modified emulsion. After the adhesive is applied, as the moisture gradually evaporates, the polymer particles that were originally maintained in a dispersed state with the effect of electrostatic repulsion and steric hindrance stabilization gradually approach. As the moisture further evaporates, the adsorption layer on the surface of the polymer particles and the cement and ceramic tile is destroyed, becoming irreversible mutual contact, achieving close accumulation. Under the force generated by the shrinking surface, the emulsion polymer particles deform and coalesce to form a film to form a continuous film with certain properties.

Back glue brushes usually have two consequences on the wall:

1. The ceramic tile back glue latex is adsorbed by the dry wall, resulting in the ceramic tile back glue being unable to form a film and lose its bonding characteristics.

2. Even if the tiles are glued on the wall, this layer of film cannot support the weight of cement mortar and ceramic tiles. Moreover, the glued on the tiles is an interface agent. Brushing on the wall will have a certain barrier to the combination of cement mortar or tiles and the base surface.

As long as the adhesive is brushed on the wall, no matter what the situation is, it will cause the tiles to fall off. Therefore, tiles with adhesive must not be brushed on the wall .
