The ProJoint SBR is a water-based emulsion designed to improve
the strength and workability of sand and cement mortar.

  • Suitable for priming the back of natural stone slabs and setts
    to promote adhesion.
  • With non-foaming properties ProJoint SBR controls the density
    of the mortar and results in a significant increase in
    compressive, tensile and flexural strength.
  • Adds additional freeze-thaw resistance.
