LANDU is a trusted manufacturer and supplier of high-quality cellulose and redispersible polymer products, committed to delivering innovative chemical modifiers for your putty formulas.
Wall putty, also called skim coat, is a decorative and functional building material made of white cement, water, and performance additives. It is widely applied to fill in cracks and holes in walls to even out the surface.
At LANDU, we provide top-quality Cellulose Ether and Redispersible Polymer Powder as chemical additives in wall putty. They can ensure smooth, long-lasting surfaces under various environmental conditions.

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.
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.
Hydroxypropyl Methyl Cellulose is a cellulose derivative that serves as an effective thickening agent. It also provides an optimal viscosity for smooth application. The ability to retain water extends the open time for the putty. In addition, HPMC can enhance the adhesion to various surfaces.
HEMC improves both adhesion and workability. Adding HEMC to your putty could minimize shrinkage during drying. This can lead to a smooth, even surface. It is noticeable that this additive is resistant to higher temperatures than HPMC.
The main function of Redispersible Polymer Powder is to improve flexibility. RDP enables your putty to withstand humidity and temperature changes without compromising performance. It also aids in forming a cohesive film to enhance the stability of your putty.
LANDU is renowned for reliability and superior quality in HPMC production. Certified by ISO 9001 and EU REACH, we consistently exceed industry standards.

he typical dosage of HPMC (Hydroxypropyl Methylcellulose) in wall putty usually ranges from 0.5% to 2% by weight of the total formulation. The exact amount can vary depending on the specific formulation requirements, desired properties (like workability, water retention, and adhesion), and other ingredients used.
For best results, it’s often recommended to conduct small-scale tests to determine the optimal dosage for your specific application.
