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

Coverage:
1kg per 50kg cement

FAQs
Yes, Larsen Powder Waterproofer increases the water repellency of render, mortar and concrete.
Larsen Powder Waterproofer repels liquid water while still allowing water vapor to pass through. This results in lower water absorption, lower risk of efflorescence and staining and higher durability over time.
Powder Waterproofer should be added to the dry components; however, it may also be added after the water. When adding to a wet mix, mixing times should be extended. See Technical Data Sheet for full information.
