KingAdd 25WP®
Powder waterproofing crystalline admixture.
Overview
KingAdd 25WP is powder waterproofing admixture Colour: formulated from selected organic salts and very fine Bulk treated silica specially designed to reduce the permeability in all cement based mortars, screeds and concrete. Chloride KingAdd 25WP blocks the natural pores in the mix and Air imparts the hydrophobic properties which reduce moisture permeability. Unique properties of KingAdd 25WP active organic chemicals reacts with the moisture in fresh concrete and Permeability generates non soluble crystal and block the pores during active hydration of cement particle. The concrete admixed VOC: with KingAdd 25WP become permanently sealed against water penetration from all sides, which also increases the ultimate strength of concrete. The advanced waterproofing properties of KingAdd 25WP also protect reinforcement against corrosion, harsh environment and waterborne chemicals like sulfates, acids and chlorides, increasing the durability and life span of concrete.
