Why tile adhesive “can not stick”?

In the process of home decoration or construction site construction, tile drums, falling off the problem is not uncommon. Have you also encountered tile adhesive is always not enough “sticky”? In fact, the root of the problem is often not in the tiles themselves, but in the formula is missing an inconspicuous but great role of the key material – HPMC ( hydroxypropyl methyl cellulose ).

Today, we will take you together to unveil the cellulose ether in the tile adhesive “thickening” secret!

A: a powerful “helper” – HPMC cellulose ether

Tile adhesive is a popular building materials used to paste tiles, its construction performance, adhesion, durability are closely related to the quality of the product. One of the fundamental reasons for “not being able to stick” is that the internal structure of the material is loose, poor water retention and insufficient bonding strength.

The main factors causing these problems include:

Rapid water loss during construction;

Thin mortar, slipping seriously;

Weak adhesion to the substrate and tile interface.

To solve these problems, we need a powerful performance “assist” – HPMC cellulose ether.

Second: where is the mystery of HPMC thickening?

HPMC cellulose ether is a kind of polymer nonionic natural derivative material, plays an irreplaceable role in tile adhesive. One of its most central role is thickening and water retention.

Specifically manifested as:

1. Improve water retention

HPMC forms a uniform gelatinous structure in the mortar, which effectively locks the water, extends the construction time, and avoids the decrease of bonding force caused by the substrate absorbing water too quickly.

2.Enhance bonding strength

HPMC improves the interface state between tile adhesive and the base and tiles, which makes the mortar fit better and effectively prevents tiles from falling off and hollowing out.

3. Improve constructability

Add HPMC tile adhesive in scraping more smooth, feel good, scraper does not “jump knife”, the construction experience is more fluent.

4. Good anti-slip effect

High-quality HPMC can significantly improve the anti-hanging performance of the mastic, even in the wall paste large-size tiles, can also be “stable”.
