UltraTech Seal & Dry SBR is a high-performance, styrene-butadiene copolymer latex used as a versatile, liquid-applied bonding agent and waterproofing compound. It significantly enhances the tensile strength, durability, and adhesion of mortar and concrete while reducing shrinkage cracks and improving abrasion resistance. It is ideal for repairing old concrete, waterproofing bathrooms, terraces, and water tanks.
