Nexus ProJoint Contract SBR – For Superior Paving Adhesion

Nexus ProJoint Contract SBR is a high-quality, water-based bonding agent designed to significantly improve the adhesion between paving slabs and bedding mortar. Formulated with modified styrene-butadiene rubber (SBR), it enhances the strength, flexibility, and durability of sand and cement mixes.

Used as a slurry primer, it promotes strong, lasting bonds—ideal for natural stone, concrete slabs, and setts. Its non-foaming properties help control mortar density while increasing compressive, tensile, and flexural strength.

Perfect for patios, driveways, paths, and commercial landscaping, ProJoint Contract SBR also provides excellent resistance to freeze/thaw cycles and long-term durability.
