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.
