Why is it important to add hpmc to tile adhesive?

HPMC can improve product functionality very well, and is now widely used in the construction industry, especially in tile adhesives.

Tile adhesive is a new modern decoration material used for pasting decorative materials such as ceramic tiles, surface tiles, and floor tiles. Is made up of cement, sand, calcium formate, and additives in a particular proportion. It has the advantages of high adhesion, good flexibility, and so on.

There are many kinds of additives in tile adhesive, but cellulose ether additives (especially hpmc and hemc) that can improve water retention, thickening effect and open time are usually added to tile adhesive.

So choosing a good tile adhesive can significantly improve your work efficiency and the aesthetics of the final result. We've put together this handy guide to help you.

What types of tile adhesive are there?

There's two different types of tile adhesive, ready mixed pastes and powdered adhesives. As the name suggests, ready mixed pastes can be used straight so they're pretty easy to use. But with ease comes limitations.

In general, pastes can only be used to fix smaller ceramic tiles to walls. On the other hand, powdered adhesives need to be mixed with water into a slurry which takes a little more time and effort. However, they offer a far stronger bond and in general, can be used to fit ceramic, porcelain and natural stone tiles to almost any substrate.

It is worth mentioning that, hpmc is an important additive to enhance the viscosity of tile adhesive. Generally, the higher the viscosity of the HPMC solution, the better the viscosity of the tile adhesive and the better the adhesion to the substrate.

The viscosity of HPMC generally refers to a particular concentration (2%) of HPMC solution, at a specified temperature (20°C) and shear rate (or rotation rate, such as 20rpm), the viscosity value measured with a specified measuring instrument.

How to choose tile adhesive?

Flexibility

Even in your home, floor tiles experience a lot of stress from foot traffic, underfloor heating and movement in the subfloor. The adhesive bed can absorb this stress to reduce the chances of your new floor cracking; the more deformable (or flexible) the adhesive, the more peace of mind you'll have.

Open Time/Setting Time

Powdered adhesives are often classified as either 'standard' or 'rapid' setting – this refers to the working time you have to use the product. The faster the adhesive sets, the sooner you can get onto grouting and finishing your room. However, there's plenty of times when you'll prefer to use an adhesive with a longer opening time – when laying large format tiles to a wall and you want to ensure a flawless finish.

Underfloor Heating

If you're looking to install either wet or electric underfloor heating, it's vital that you use a flexible tile adhesive. The heating and cooling processes generate considerable stresses and a flexible adhesive will absorb these, reducing the chances of your tiles cracking over time. However, we'd really recommend using a self-levelling compound to cover the cables and provide a perfectly flat surface to tile onto.

Primer

Absorbent surfaces such as plaster can suck the water out of the tile adhesive, reducing the bond strength and working time. It is very necessary to choose tile adhesive with good water retention.

Of course, the performance I mentioned here can be improved by adding hpmc to achieve the final effect you want. HPMC is playing an essential role in tile adhesives to improve the key properties like water retention, slip resistance, and workability, etc.

Are there any other benefits of adding hpmc?

It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel, and protetive colloid properties of surface activity and maintain moisture function properties ect. Is used for wall putty, tile adhesive, cement mortar, dry mix mortar, wall plaster, skim coat, mortar, concrete admixtures, cement, gypsum plaster, joints fillers, crack filler, etc.

Now! Through the above explanation, briefly summarize the benefits of adding hpmc to tile adhesive:

Very good open time

High water retention

Thermal stability improved

Less retardation of cement hydration

Excellent sag resistance

Good consistency

Good workability: easy use

Good anti-crack, anti-shrinkage

Obviously, adding hpmc to tile adhesive is very necessary.

The ultimate guide on HPMC and how to buy?

According to the application field, HPMC is divided into construction-grade HPMC, daily chemical-grade HPMC, food-grade HPMC, and pharmaceutical-grade HPMC. The tile adhesive uses HPMC and belongs to the building material grade.

Viscosity is an indispensable indicator of HPMC. According to different viscosity, HPMC can be divided into three grades: low, medium and high, and because of the other properties of hpmc, we have further subdivided many grades.
