Review: Great value - A good product
Review: Happy builder! - I used to be perfectly happy using my local branch of Travis Perkins' own brand of plasticiser (which they still stock but only in 25L tubs, which is a pain to decant), but then they started to stock Everbuild plasticiser, instead, which is complete and total garbage. The only brand of SBR that i have ever used is also by Cementone and it is truly A1 when it comes to quality and so i thought why not give this a go? Simply put, i will never again buy any plasticiser other than this. Super concentrated, so you only need a tiny bit and it makes the most lovely, rich mortar. Very impressed.

*by A***S on 16 June 2018*

I am a novice mortar mixer so poorly experienced to comment, but I followed the instructions and it seemed to work. I didn't want to mix and use a batch without it to find out!
