What is RDP?

RDP, or Redispersible Polymer Powder, is a powdered polymer that, when mixed with water, can provide various benefits to cement-based products. It improves flexibility, adhesion, and workability, making it an essential additive in cement plaster. Utilizing RDP can enhance both the aesthetic and functional properties of your plaster, but selecting the right product is crucial.

Reasons to Use RDP in Cement Plaster

  1. Enhanced Adhesion: RDP generally enhances the bonding strength of cement plaster to substrates, ensuring a stronger and longer-lasting finish.

  2. Increased Flexibility: By adding RDP, your plaster becomes more flexible, which helps it to better accommodate structural movements.

  3. Water Resistance: Some RDP formulations offer improved water resistance, making your plaster suitable for damp environments.
