Larsen Powder Waterproofer 1kg

Larsen 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
