Is the stickier the tile adhesive, the better?

Tile adhesive is a product composed of high molecular polymer emulsion and inorganic silicate. It can be used in combination with a variety of bonding materials to form a tile paving system to improve the adhesion between the tiles and the base layer.

As people's pursuit of quality of life continues to improve, more and more high-end ceramic tiles such as microcrystalline stone, vitrified tiles, marble, etc. are widely used in the market, and large-size ceramic tile paving has gradually become mainstream, which is important for Ceramic tile paving materials pose higher requirements and challenges.

So, when it comes to tile adhesives, is the stickier the better?

There is a misconception in the market recently that the stronger the viscosity of the tile adhesive, the better the quality, but this is not the case. Different from the general bonding relationship between glue and paper, ceramic tile paving does not rely solely on the viscosity of the emulsion to bond the tiles, but uses the flexibility of the tile adhesive film to buffer the connection between the tiles and the wall. The stress between them can achieve the purpose of firmly sticking and avoiding hollowing out.

In addition to the initial viscosity, factors such as the viscosity, weather resistance, and cohesion of the tile adhesive also have an important impact on its adhesion. These four characteristics complement and influence each other, and an optimal combination needs to be found at a balance point between them. If the initial viscosity is too strong, the holding viscosity will become weak and the service life will be short;

At the same time, the worse the water resistance, high and low temperature resistance, and aging resistance, the easier it is for the adhesive to degrade due to changes in the external environment. In addition, the stronger the initial viscosity, the stronger the flexibility, but the weaker the cohesion, the worse the load-bearing extrusion ability. Under long-term action, ceramic tiles and mortar are prone to problems such as hollowing, peeling, and falling off.

Therefore, judging the quality of tile adhesive cannot be judged from the simple surface characteristic of whether it is sticky to the hand. Instead, comprehensive considerations should be made from multiple aspects such as flexibility, weather resistance, water resistance, alkali resistance, and environmental protection. Only by finding the balance point of various characteristics can we choose a high-quality tile adhesive, so that after the tiles are laid on the wall, they can be firmly fixed on the wall, effectively improving the safety performance of the tiles.
