ProJoint High Performance SBR

Description

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*.

As a water-based emulsion of a modified styrene-butadine polymner both ProJoint SBR products have 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.
