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
