Benefits of Additives in cement render
LANDU is a trusted manufacturer and supplier of high-quality cellulose and redispersible polymer products, committed to delivering innovative chemical modifiers for your plaster formulas.
LANDERCOLL K100G HPMC is one of our most popular additives for cement render. Its excellent water retention ensures the optimal hydration level of the cement, resulting in improved workability and smoother application. It also provides a strong bond to surfaces. This can prevent cracks and improve the durability of your render. Besides, LANDERCOLL K100G HPMC makes it easier for your plaster to achieve a flawless, even finish.
As a top Cellulose Ether & Redispersible Polymer Powder supplier, LANDU can provide custom cement render modifiers. They will best suit your raw materials and local needs.
Of the additives in cement render, Hydroxypropyl Methylcellulose (HPMC) is the most important. HPMC can improve the render’s workability and water retention, no matter whether on both indoor and outdoor walls. This results in a smoother surface while preventing the render from drying out too quickly.
Methyl Hydroxyethyl Cellulose (MHEC/HEMC) is a common water-retaining agent and thickener. This additive is resistant to higher temperatures of 75 – 100 ℃ compared to 55 – 75 ℃ for HPMC.
Redispersible Polymer Powder enhances the bond strength between the render and the substrate. This additive ensures the render doesn’t peel off or detach over time. It also helps the render to be more resistant to freeze-thaw cycles.
LANDU is renowned for reliability and superior quality in HPMC production. Certified by ISO 9001 and EU REACH, we consistently exceed industry standards. For example, during production, we use vertical reactors and cyclone mixing technologies to achieve more complete and thorough mixing. Our precise methods ensure that our customers receive only the best, most reliable products.

Surface preparation involves cleaning the area, repairing any damage, and ensuring the surface is dry and stable. For optimal adhesion, it’s also recommended to apply a bonding agent or dampen the surface before rendering.
Regular maintenance involves cleaning the surface with water and a soft brush to remove dirt and mold. Avoid harsh chemicals that could damage the render. Repaint as needed to maintain appearance and protection.
Yes, cement render can be used on interior walls, particularly in areas prone to moisture, like bathrooms or kitchens. Ensure proper ventilation and drying conditions during application.
While it’s possible to apply cement render in humid conditions, it’s important to monitor moisture levels. Excessive moisture can affect adhesion and curing. Ideally, aim for dry conditions or use specialized products designed for such environments.
