RDP Powder For Wall Putty

Redispersible polymer powder is made by water-based emulsion using a spray-drying process. It dissolves quickly in water, forming an emulsion.


RDP powder is a key part of putty, and it plays an important role in how well the putty sticks. Increasing the amount of RDP powder results in a higher bonding strength.


WOTAIchem is a professional VAE RDP powder manufacturer. Our products are suitable for both internal and external wall putty.


1. Improve putty adhesion and flexural strength. Excellent resistance to impact, and cracks.

2. Improve water retention of the putty mixture. Extends opening time and workability.

3. RDP powder promotes a long-lasting putty finish with smooth results!

Major Advantage of RDP Powder in Wall Putty

WOTAIchem RDP Powder for Wall Putty

Water-Resistant and Elasticity

RDP is easily soluble in water and quickly dispersed into the emulsions. It shares the same characteristics as the initial emulsion liquid phase.


After water evaporates, RDP can form a film with high elasticity, high tensile strength, high weather resistance and high adhesion to the substrate.

Wall Putty Cracks: Causes and Solutions?
Causes of Wall Putty Cracks:

1. Poor Base Adhesion: When the surface is loose or unstable, and joint treatment is insufficient.
2. Excessive Thickness: Applying a single, overly thick coat that dries quickly can lead to surface cracks as the outer layer dries faster than the inner layers.
3. Incompatible Putty Layers: Mismatched putty layers with varying hardness and composition can result in cracking.
4. Contaminated Putty: Mixing putty with substances other than water can cause cracks.



1. Ensure Stable Structure: Only apply putty once the underlying structure is stable to prevent future cracks.
2. Proper Joint Treatment: Address any cracks or joints in the cement mortar or substrate before applying putty.


What is the role of RDP powder in interior wall putty?
RDP(Redispersible Polymer) Powder can improve the adhesive properties, workability, and flexibility of interior wall putty. WOTAIchem’s RDP-produced putty powder offers the following advantages:
  1. Enhanced Adhesion: RDP increases bonding strength for better adhesion to various substrates.
  2. Improved Coverage and Workability: The presence of RDP results in a smoother and more even wall surface, making application easier and faster.
  3. Crack and Wrinkle Resistance: RDP helps prevent cracks and wrinkles, ensuring a smooth and durable wall finish.
  4. Efficient Filling and Seam Performance: RDP allows for efficient hole filling and seamless integration between wall sections, ensuring a high-quality finish.
What happens when there is insufficient glue in a putty?

Insufficient glue in putty is a direct result of a loose layer of putty. A chalky surface, high paint consumption when painting, poor levelling and a rough surface, makes it difficult to form a thick paint film. The wall surface will be peeling, blistering, peeling and cracking. To completely solve these possibilities, purchasing quality putty and emulsion powder is necessary.

What is powder wall putty?

Powder wall putty is a fine powdery substance used in construction to prepare and smoothen wall surfaces before painting or applying. Wall putty is made from white cement, polymers, and other additives. It is mixed with water to form a smooth paste that fills in cracks, holes, and imperfections on walls. This ensures a smooth and even surface that enhances the final finish of the wall.

How does a putty bulge arise?

Improper treatment of the substrate. So the putty layer does not contact the substrate closely enough, forming an interlayer. A dense layer between the substrate and the putty layer prevents the air from diffusing properly towards the substrate.

After scraping the putty, what is the cause of the yellowing in places? What should I do?
The second coat of putty before the first coat is dry will often result in yellowing. If the water content is high, and there is no sealing before the putty is put on, this can cause yellowing.
If the yellowing is caused by scraping the second coat of putty before the first coat has dried, you can use white paint to cover it. However, if the yellowing is caused by the water content of the wall, and not waterproof putty. It is best to remove it and redo it.
What will happen if I scrape a second coat of putty before the first one is dry?

Over time, it will peel and sometimes turn yellow.

How long does it take for the water-resistant putty to dry on the wall in sunny and dry weather?

Wall putty usually takes 2-3 days to dry with the windows open.
