"I use this sbr as a primer before tiling onto plaster. Its good value for money. As any proper tiler will tell you, always use sbr for priming and DO NOT use PVA. Pva is affected by the moisture in the adhesive and can cause tile failure."
"SBR blows PVA away when it comes to performance, better mix, better adhesion, denser mix, stronger end product , it's a pity its so expensive but if you have a tough job with mortar or concrete this will make it easier with a better result"
"DIYers use unibond, TRADES use this. Mixed correctly this material is second to none. Outstanding!! I have used this material for over fifteen years from different manufacturers and have never had a problem. When working with other trades on site they all get converted. TRY IT! you will never use unibond (PVA or EVA) again. This is a good price for an exceptional product"
