Dry Mix Mortars Construction Redispersible Polymer Powder

April 3rd 2024

Dry mix mortars are pre-blended mixtures of cement, sand, and other dry ingredients that only need water to be added at the job site. This makes them a convenient and versatile construction material for a variety of applications.

Redispersible polymer powder (RDP) is an important additive for dry mix mortars. It is a spray-dried powder of polymer emulsion that is re-emulsified with water when mixed. RDP improves the properties of dry mix mortars in several ways, including:

  • Increased adhesion: RDP helps the mortar to bond better to a variety of substrates, such as concrete, brick, and tile.
  • Improved flexibility: RDP makes the mortar more flexible, which helps to resist cracking and spalling.
  • Increased water resistance: RDP can help to improve the water resistance of mortar, which is important for applications such as exterior walls and floors.
  • Improved workability: RDP can make the mortar more workable, which makes it easier to apply.
