Redispersible Polymer Powder (RDP) for Cementitious Waterproofing & Fracture Fixing
What It Is
Redispersible Polymer Powder (RDP) is a free-flowing, white powder made from specially customized plastic acetate-ethylene (VAE) or acrylic copolymers. When blended with water and cement-based materials, it forms a flexible, sturdy polymer movie that bonds securely to concrete and masonry surface areas.
Key Conveniences
This RDP additive substantially improves the efficiency of cementitious waterproofing slurries, tile adhesives, and fracture repair work mortars. It boosts bond to both permeable and non-porous substrates. It likewise enhances adaptability, which assists avoid new cracks from creating. The powder enhances water resistance while keeping vapor permeability– so walls can “take a breath” without allowing fluid water via. Workability and open time enhance also, offering installers a lot more control during application.
Just how It Functions
When added to completely dry mix formulas, RDP remains steady in storage. Throughout mixing with water on-site, the powder redisperses into little polymer particles. These fragments coat cement grains and fill up micro-pores as the mix cures. The outcome is a tougher, much more cohesive matrix that withstands cracking under anxiety and obstructs water infiltration efficiently.
Regular Applications
Utilize this RDP in:
– Waterproofing layers for cellars, balconies, and roofs
– Adaptable fracture shot and surface fixing mortars
– Polymer-modified tile adhesives and renders
– Outside insulation finishing systems (EIFS).
Handling & Storage space
Store the powder in an amazing, completely dry area in secured bags. Keep away from moisture. Usage within 12 months of manufacturing for finest outcomes. Constantly follow safety and security guidelines when taking care of fine powders– put on handwear covers and eye security.
