Make Perfect Wall Putty with HPMC

Ⅰ. Understanding the Component of Wall Putty

What is Wall Putty Made of? Wall putty is mainly made of white cement, polymers, fillers, and additives.

-White cement: A major component of wall putty formula. It provides the main structure and strength.
-Fillers: Common fillers include fine powders like calcium carbonate or dolomite. They improve the flexibility, adhesion, and workability of the putty.
-Polymers: Redispersible polymer powder is the most crucial polymer that is often used in putty. It has amazing features, such as slip resistance and crack resistance.
-Additives: Improve specific properties like drying time, water resistance, and crack prevention. The most popular admixture in putty is HPMC.
-Pigments: Add color to the putty if a specific shade is desired.

Ⅱ. Three Easy Steps to Make Wall Putty with HPMC

How to make wall putty paste? Making wall putty paste requires only three steps: preparing materials, mixing, and checking.


1. Prepare Raw Materials.
Gather all the materials you need. White cement, RDP powder, fillers such as calcium carbonate. Measure the right amount of HPMC hydroxypropyl methylcellulose and add it to wall putty formulation. Prepare some water.


2. Mixing Procedure.
Add all the ingredients together, and add water to the compound. Start stirring until they are evenly mixed. Use a putty mixer to achieve an even distribution. This ensures the HPMC spreads evenly, giving you consistent performance.


3. Checking the Mixture.
Mix the compound until the paste becomes creamy and consistency. That is easy to spread onto the wall. Then the putty is ready to apply!

Ⅲ. The Power of HPMC in Wall Putty

HPMC is a special admixture that can improve your wall putty in remarkable ways. It helps the putty stick better to surfaces and last longer. HPMC also reduces cracks and flaws on walls, giving you a smooth and perfect finish.


Ⅳ. Choosing the Best HPMC for Wall Putty

Getting the right HPMC for your wall putty is crucial. There are a few things that need to be taken into consideration, such as the level of thickness and the amount you’re using.


HPMC comes with different viscosity rates. The higher the viscosity, the thicker the consistency will be. Lower viscosity HPMC is more suitable for self-leveling projects, and slightly higher viscosity is made for wall putty and tile adhesive. Each one was made for different jobs.


The viscosity matters, as well as the dosage. Getting the right amount of HPMC mixed in with your wall putty is really important to make sure it works just like you want it to.

Ⅴ. Wall Putty Application Techniques

How to use wall putty? Wall putty powder is made from white cement, often used to smooth out indoor and outdoor walls. It can be applied to various surfaces, such as plasterboard or concrete. It is especially useful for filling cracks and holes.


>>Applying wall putty requires following best practices to achieve an even and smooth wall finish.
>>Prepare the surface, remove any loose materials.
>>Wall putty or primer first? Apply primer first before putty application. Primer helps the putty to stick better.
>>Use recommended tools and methods. The wall putty paste is applied with a trowel onto the wall, about 1-2mm thick.
>>Allow enough time for setting and drying.

Ⅵ. Dealing with Common Issues in Wall Putty

We may encounter some common issues during and after the wall putty application. For example, cracking, inconsistent drying, uneven textures, or lack of adhesion.


Such problems occur; it’s important to adjust the mixture ratio for each component. Or use a specific application method. These steps can help reduce the chance of the above issues. Ensure a smoother finish on your walls.
