Sika Everbuild 503 Premium S.B.R. Bond Admixture – Water Resistant Bonding Agent – White – 2.5 litre

Everbuild 503 Premium S.B.R. Bond Admixture is a styrene-butadiene, synthetic rubber (latex-based) water resistant bonding agent and admixture for use in areas subject to humidity, dampness and water contact including vapour. Add to mortar, screeds, and renders to greatly improve adhesion to a wide range of substrates including dense concrete, steel, tiles and more. S.B.R. improves water resistance of cement mixtures by forming a reinforcing polymer that increases long-term durability and flexibility of the mix on renderings and floor screeds. 503 Premium S.B.R. Bond Admixture contains anti-foam to control the density of cementitious mixes. Use 503 Premium S.B.R. Bond Admixture to greatly improve resistance to many chemicals as well as improve frost resistance due to a reduced water: cement ratio, giving the added benefit of improving workability. 503 Premium S.B.R. Bond Admixture can also be used as a primer or sealer in tiling applications. Finally, in comparison to PVA, 503 SBR Bond is not adversely affected in wet conditions and therefore is recommended for exterior use.
