MasterLife® WP 707
Low dosage, liquid, integral waterproofer
DESCRIPTION ACTION
A liquid admixture for concrete to give high water MasterLife WP 707 assists in the production of
resistance, based upon a blend of surface active water resistant concrete by its two fold action:
agents and refined lignosulphonate. Waterproof
