Bond is a 25L latex-based polymer admixture that significantly improves adhesion, water resistance, and durability of cement mixes. Ideal for use in humid, damp, or exterior conditions, it enhances mortar, screeds, and renders on multiple substrates including concrete, steel, and tiles. Its advanced formula also boosts chemical and frost resistance, making it a must-have for professional builders seeking long-lasting, high-performance results. ## Description Product Description 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.

I assume you are proposing to use it as an additive for brick mortar? I have no knowledge of it for this application I am afraid. **Q: Can I use this on the back of 20mm porclain garden tiles** A: Yes. It is ideal for creating a slurry with cement applied with a brush to the back of a 20 mm ceramic tile. It is a water proof when dry bridging agent. **Q: Would this product work as an exterior treatment to stabilise 100 year old flaking/weathered sandstone blocks?** A: Watered down it may work as a seal but it is intended to bond other materials not just seal one, it may also leave an unwanted sheen. I think there would be a better alternative out there. **Q: Will it bond to exterior if painted for rerendering?** A: This would depend on the paint application, however, we would advise to remove the paint prior to any render application. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It’s SBR.. *by N***R on 14 June 2026* It’s SBR.
