Increase Adhesion, Flexibility, and Durability

4025N RDP is a semi-flexible redispersible polymer powder that improves bonding strength and crack resistance in wall putty. It forms a flexible polymer film as the putty dries, enhancing durability and surface smoothness.

Key Benefits:

Improved adhesion on all wall surfaces

Flexibility to reduce shrinkage and micro-cracks

Durable, smooth, and long-lasting finish

Suitable for interior and exterior walls

LANDU provides technical support for precise formulation guidance.

Can LANDU additives improve workability and open time for cement-based putty?

A: Absolutely. HPMC and HEMC increase water retention, extend open time, and make the putty easier to spread, ensuring smoother and more uniform surfaces.

Are LANDU wall putty additives suitable for exterior applications?

A: Yes. With RDP and HEMC, additives enhance adhesion, flexibility, and resistance to temperature, moisture, and UV exposure, making them ideal for exterior facades.

Can I combine LANDU HPMC/HEMC with RDP in a single formulation?

A: Yes. Combining cellulose ether + RDP ensures the best balance of workability, adhesion, crack resistance, and durability.

Q10

How do additives prevent the putty from drying too fast?

A: HPMC and HEMC retain water in the mix, slowing down drying and extending open time. This prevents cracks, improves adhesion, and ensures smooth application.

Q11

How can I reduce powdering or flaking of wall putty?

A: Powdering usually results from poor bonding or rapid moisture loss. Using LANDU HPMC/HEMC + RDP improves adhesion, water retention, and film formation, minimizing powdering.

Q12

Do LANDU additives work with both interior and exterior wall putty?

A: Yes. Additives are suitable for interior living spaces, offices, hotels as well as exterior facades and high-traffic areas, providing consistent performance under different environmental conditions.
