Nexus ProJoint Contract SBR – for greater adhesion of paving to bedding mortar!

We highly recommend that to achieve the best possible outcome for any paving project, an SBR is used prior to laying the paving. Used within the mortar mix or applied neat to the underside of paving, an SBR such as ProJoint Contract SBR will greatly improve adhesion of the paving slabs to the mortar bed, improving the life of the patio.

As a water-based emulsion, ProJoint High Performance SBR has been designed with non-foaming properties to:

• 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

ProJoint High Performance 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.

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