SBR – cement additive to improve flow, bonding and waterproofing properties


SBR is a styrene-butadiene co-polymer emulsion which imparts beneficial property improvements to cementitious mixes.

After appropriate dilution with water, the resultant liquid may be used to gauge the cementitious mix to the desired consistency.

A reduced water:cement ratio leads to superior mechanical properties, and resistance to moisture ingress.

Typical Uses

a) Flooring: screeds and patch repairs in dairies, abattoirs, breweries, factories etc.

b) Bonding additive: renders, slip bricks, tiles, coping stones, etc.

c) Concrete repair: making good structural concrete, increase in effective concrete cover.
