Powder Waterproofer

Powder Waterproofer is a white powder admixture used to increase the water repellency of render, mortar and concrete.

By increasing the water repellency but maintaining the vapour permeability of a mix, there is a lower water absorption, lower risk of efflorescence and staining and a higher durability. Use of Powder Waterprooofer in render base coats also reduces the suction to allow easier application of following render coats.



  • Permeability and absorption reduced
  • Vapour permeable – allows structure to ‘breathe’
  • Helps prevent efflorescence
  • Easy to use


Packaging: 1kg plastic bags

Dosage: 1kg per 50kg cement
