• ProJoint™ SBR  

    To achieve the best possible outcome for any paving project, we recommend that an SBR is used prior to laying the paving. 

    Nexus Paving Systems have developed a quality High Performance SBR together with a Contract SBR to provide reassurance that the bedding material will benefit from greater adhesion and will meet the demands of any project*.

    *Not suitable for porcelain products, please refer to the ProJoint Porcelain Primer if using porcelain paving.

The ProJoint SBR products have been designed with non-foaming properties to control the density of mortar and:

  • promote adhesion of natural stone and concrete paving to substrates;
  • improve strength and workability of a sand and cement mortar;
  • increase water resistance and durability of mortar;
  • increase the compressive, tensile and flexural strength of mortar.

Both ProJoint High Performance SBR and ProJoint Contract SBR can be applied neat to the underside of paving substrates as a primer and adhesion promoter.  The addition rate depends on the application however, as a guide, typical addition is 200ml per 1kg of cement - full details are available.
