SBR Admixture

Bonding and waterproofing aid for mortars and screeds.

A styrene butadiene copolymer latex, which increases flexibility of cement screeds and mortars and improves water and chemical resistance and durability.

Features & Benefits: Increases flexibility of cement screeds. - Improves workability, wet adhesion and plasticity of fresh mortars. - Reduces shrinkage, cracking and surface dusting. - Improves water, abrasion and chemical resistance. - For interior and exterior use. 

Uses: Suitable for internal and external floors and rendering in areas of continual or intermittent water and chemical contact. Excellent waterproofing admixture that improves adhesion of cementitious screeds and reduces shrinkage and cracking when repairing floor screeds. Also ideal as a bonding agent for new to old concrete. Can be used as a bonding agent, as an admixture or general purpose primer (tiling etc). For improving a mortar's, render's or floor screed's abrasion and chemical resistance. Key coat applications to substrates with a low porosity. For repair patching of concrete and cement screeds, to improve adhesion and flexibility of screeds.
