Products for Wall Putty, Render
RDP, HPMC, and HEMC are fundamental functional additives in both plaster and wall putty formulations, working synergistically to define the key performance of these materials.
In Plaster, the combination provides cohesion, workability, and durability. RDP enhances the adhesive strength to the substrate, improves flexibility to resist cracking, and increases impact resistance. HPMC/HEMC deliver essential water retention, ensuring proper cement hydration in thick-layer applications, and they provide the necessary consistency and anti-sag properties for easy application and good build-up.
In Wall Putty, the trio ensures a smooth, crack-resistant finish. RDP improves adhesion to the base plaster, increases surface hardness, and provides crucial flexibility to bridge micro-cracks. HPMC/HEMC are vital for water retention, preventing the putty from drying too quickly and allowing for extended workability and effortless sanding. They also enhance the lubricity for a very smooth trowel application.
Across both applications, this combination ensures optimal processability, reliable performance, and a durable final finish.
