K-Seal SBR
K-Seal SBR is a Styrene Butadiene Rubber latex bonding agent that dramatically improves the adhesion, flexibility, and waterproofing of cement-based mixes. Add it to cement plaster, screed, or concrete to create crack-resistant, waterproof repairs. Use as a primer before plastering over old concrete for superior bonding. A versatile product used extensively in construction for concrete repair, waterproofing, and improving the durability of cement-based applications.
