When I first got it, I diluted it. It worked, but I found a better result using it neat. ### ⭐⭐⭐⭐⭐ Delivered promptly and fit the description. *by D***S on 4 March 2026* Good value, does the job very well. Delivered promptly. ### ⭐⭐⭐⭐ Good Stuff but the Container Lid Will Drive You Nuts *by A***Y on 27 January 2024* Thought I’d try this as an alternative to PVA for plastering after seeing a video recommending it. As advised applied it neat and it worked a treat. I like the idea that it’s not water soluble once dry, so it’s good for any areas that might be prone to dampness. Don’t know how this compares to other brands of SBR as I usually use PVA but happy with this one, good consistency, application and bonds well with one light thin coat and it goes far. Would recommend but with one mountainous proviso, once you manage to open the thing pour the contents into a different container because that lid is an absolute pig of a thing to open and will frustrate you to anger. I’m not a fan of child proof lids for adults but this push down and turn fifty times before it opens is next level nonsense. On the basis of it’s what’s inside that counts full marks but if I was writing this while trying to get the thing open it would be something expletively nearer a zero. That said and on balance, if you can swap the contents into a different container then it’s pretty dammed good – with just one star off overall for the crazy lid. ## Frequently Bought Together - Everbuild 503 Premium S.B.R.
