Polybond SBR

Polybond SBR is a Styrene Butadiene Rubber copolymer based product which is used in mortar and concrete as an admixture and bonding agent to increase its water resistance and durability.


  • Enhances the flexural and tensile strength of the mortar and render.
  • Provides good resistance to water and moisture vapour transmission.
  • Improves the chemical and abrasion resistant properties of the mortar.
  • Can be applied in thin screed without cracking.
  • Reduces the water/cement ratio.
  • Easy to use.
  • Compatible with all types of cements.
  • Reduces shrinkage.
  • Prevents bleeding.
  • Excellent adhesion to most building materials.
  • Good resistance to salt permeation.
  • Prolonged corrosion protection.
  • Similar thermal expansion and modulus properties like concrete.
  • Can be used in potable water applications.
Fields of applicationBonding: For bonding of new to old concrete, tile bedding and fixing of slip bricks.
  • Waterproofing Internally: Basements, Swimming pools, Potable water tanks, sludge tanks & ducts, tunnels and underpasses.
  • Waterproofing externally: Structures above ground
  • Waterproofing suspended floors: Patios, walkways, balconies, wet areas, plant rooms.
  • Waterproof bonding: Bricks slips, copings, Pre-cast treads and risers.
  • Waterproof/Protective Slurries: Potable water tanks, sewerage and mild chemical holding tanks, porous concrete, block work and long term protection of reinforcements or friable concrete soffits.
  • Repair of Concrete.
  • Admixture: As an admixture for cementitious systems. Improves the durability, water proofing and abrasion resistance properties of mortars.
