Fosroc SBR 300 — SBR waterproofing coating & concrete bonding agent
Fosroc SBR 300 is a premium SBR (Styrene Butadiene Rubber) waterproofing coating from Fosroc Chemicals India Pvt. Ltd. — a versatile, rubber-based polymer solution engineered for both waterproofing and bonding applications in concrete and plaster construction.
When blended into cement mortars, repair mixes, or applied as a bonding slurry, SBR 300 dramatically improves adhesion, flexibility, and water resistance of cementitious substrates. It is extensively used as a waterproofing chemical for roof waterproofing, terrace waterproofing, basement waterproofing, water tanks, and bathroom applications — delivering robust, long-lasting protection against water ingress and moisture penetration.
Its SBR formulation enhances tensile and flexural strength, reduces drying shrinkage cracking, and creates a highly durable, impermeable layer — making it a dependable construction chemical trusted by applicators and contractors across India for its strong reliability, user-friendly application, and consistent on-site performance.
