Why use tile adhesive and tile back adhesive?

Traditional cement mortar can be used to lay ceramic tiles. Why do we need to use tile adhesive or tile back adhesive? The reason is actually very simple: we know that many people now like “floor tiles on the wall”. Many ceramic tiles have relatively low water absorption, large sizes, and heavy weight. If traditional cement mortar is used for paving, what will happen after the ceramic tiles are laid on the wall?

Ceramic tiles do not absorb water, leaving many pores after the cement mortar dries. Coupled with the influence of its own gravity, wall tiles are likely to hollow and fall off. Therefore, for laying floor tiles on the wall, it is not possible to use the traditional cement mortar paving method.
There are a lot of additives in tile adhesive that can enhance the adhesion. Therefore, there are no problems such as low water absorption and too heavy weight of ceramic tiles. In addition, compared to traditional cement mortar, tile adhesive also has certain advantages in terms of waterproofing, impermeability, freeze resistance, and high temperature resistance. It is thinner and more space-saving than cement mortar.
As for the tile backing adhesive, it plays a “transition” role between the back of the tile and the cement mortar. Ceramic tiles do not need to be in direct contact with cement mortar. So it can also avoid problems such as wall tiles hollowing out and falling off due to traditional cement mortar laying of wall tiles.
