SBR Bond

SBR Bond can be mixed with cement as a bonding slurry for screeds, renders and mortars.


A highly concentrated styrene butadiene emulsion used to make polymer mortars, screeds and renders. The improvements allow the production of high strength wearing screeds, thin section screeds, repair mortars and waterproof mortars.


SBR Bond can be mixed with cement as a bonding slurry for screeds, renders and mortars.


  • Highly concentrated - economical.
  • Greatly improves flexural strength of the mortar.
  • Improves tensile strength.
  • Increases the abrasion resistance of the mortar.
  • Improves chemical resistance.
  • Reduces shrinkage.
  • Reduces water permeability.
  • Excellent adhesion to steel, glass, asphalt.
  • Suitable for both positive and negative water pressure applications.
  • Environmentally friendly, non-toxic and chloride free.
