Can hydroxypropyl methylcellulose (HPMC) added to tile adhesives and latex paints prevent cracking?

Hydroxypropyl methylcellulose (HPMC) can thicken, retain water, and improve rheology in ceramic tile adhesives and latex paints, thereby improving material performance and construction efficiency. However, it does not directly prevent cracking of tile glue and latex paint.

Hydroxypropyl methylcellulose (HPMC) is used in tile adhesives and latex paints

Cracking of ceramic tile glue and latex paint is usually caused by uneven base layer, insufficient base layer strength, improper construction, etc. Therefore, before using tile glue and latex paint, the base layer needs to be fully treated and reinforced to ensure the flatness and strength of the base layer. In addition, it is also necessary to pay attention to construction technology and construction environment during the construction process to avoid excessive extrusion, excessive stretching, excessive high or low temperature, etc., thereby reducing the risk of cracking.

In short, hydroxypropyl methylcellulose (HPMC) can improve the performance and construction efficiency of ceramic tile glue and latex paint, but it cannot directly prevent cracking. The base layer needs to be fully treated and reinforced before construction, while paying attention to construction technology and construction environment to reduce the risk of cracking.
