Description
The ProJointTM SBR is a water-based emulsion of a modified styrene-butadine polymer. This has been designed to improve the strength and workability of sand and cement mortar. It can also be used for priming the surface of natural stone or cement slabs or setts to promote adhesion.
With non-foaming properties ProJointTM SBR controls the density of the mortar and results in a significant increase in compressive, tensile and flexural strength.
Key Facts
- High solid content of over 30%
- Excellent freeze-thaw resistance
- Improves strength and workability of mortar
- Promotes adhesion of natural stone and concrete paving to substrates
(Typical addition is 200ml per 1kg of cement)
