Wall Putty Additive for Smooth and Durable Finishes

What is Skim Coat/Wall Putty?

Wall putty, also known as skim coat, is an essential finishing material in decoration. It is used to eliminate surface defects and smooth the substrate. There are three common types of wall putty:

  • Ordinary Putty: A basic formulation used for general-purpose surface leveling and smoothing.
  • Flexible Putty: Designed for applications where walls or surfaces are subject to minor movements, temperature changes, or vibrations.
  • Elastic Putty: A highly elastic variant designed for surfaces prone to frequent expansion or contraction, ensuring a long-lasting, crack-free finish.

In wall putty applications, precision and performance matter. LANDU recommends our game-changing additives, including HPMC and Redispersible Polymer Powder, which ensure your putty outperforms expectations. Contact LANDU today for premium solutions tailored to your needs!

RDP For Wall putty formula

LANDERCOLL®

HPMC K100

LANDERCOLL K100 HPMC additive retains moisture effectively. It can remain putty workable for longer periods while reducing the risk of drying out and shrinkage during application. Also, our HPMC provides excellent thickening effects, creating a smooth and creamy texture. It helps improve the adhesion of the wall putty to various substrates.

ACCURATE™

RDP 5025N

Wall putty with ACCURATE 5025N RDP modifier can withstand slight movements in the substrate without cracking due to the increased flexibility. This is particularly important in dynamic environments. It can also protect the putty from moisture ingress and reduce the risk of mold and mildew growth. ACCURATE 5025N RDP contributes to the overall durability, making the putty more resistant to temperature fluctuations and humidity changes.

How to Prevent Bubbling in Wall Putty

Putty bubbling occurs when air or moisture is trapped within the mixutre. To prevent this issue, consider the following key points during construction:

During the mixing process, HPMC’s properties allow for better dispersion of air. When mixed properly, it helps release trapped air, leading to a smoother, bubble-free putty that’s easier to apply.
