SBR waterproofing chemical is a synthetic rubber based liquid polymer used to improve the waterproofing and bonding properties of cement based materials. It is commonly mixed with cement mortar or concrete to enhance adhesion flexibility and durability. The chemical helps reduce water permeability and increases resistance to cracking shrinkage and abrasion. It also improves workability and provides better bonding between old and new concrete surfaces. SBR waterproofing chemical is widely used in bathrooms terraces roofs basements water tanks and repair works where long lasting waterproof protection is required.
