WaterBlazer SBR is a liquid polymer additive formulated from styrene?butadiene rubber latex. It is designed to enhance the performance of cement-based materials such as mortars, plasters and screeds. When blended with cement mixtures, the polymer improves adhesion, flexibility and resistance to water penetration. It is widely used for waterproofing treatments, repair mortars, bonding coats and polymer?modified cementitious systems.
