Polywed’s Asuka is a general-purpose waterproofing powder admixture used to increase the water repellence of render, mortar, and concrete. By increasing the water repellence and maintaining the vapor permeability of a mix, there is lower water absorption, lower risk of efflorescence, and staining and higher durability.

1. Rending base coats and reduces the suction to allow easier application of following render coats.
2. Waterproofing of precast concrete and waterproofing of cement plasters.
