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.
Key Benefits of Nexus ProJoint Contract SBR
- Enhances adhesion between slabs and bedding mortar
- Suitable for natural stone, and concrete
- Improves flexibility, strength, and water resistance
- Helps prevent lifting, cracking, and bedding failure
- Easy to mix and apply as a slurry with cement
- Ideal for patios, paths, driveways, and high-traffic areas
- Used as part of a full paving system, Nexus ProJoint Contract SBR supports long-lasting, stable installations you can trust.
- For stronger, more durable paving projects
*Not suitable for porcelain products, please refer to the ProJoint Porcelain Primer if using porcelain paving.
