Just a quick update. Was in CTD so got some of their weber joint pro grout. I had 30 metres of metro tiles to grout and thought I would give it a go to see how smooth it was after Beanz mentioning it earlier in this thread.
When I first mixed it it seemed quite creamy in colour but it has dried back white, not as white as Bal microflex but most definately white. The texture is very smooth and have to say cleaned off far easier than Bal.
Would recommend this for anyone looking for a nice smooth grout though it does take a while to get used to if you are a Bal/Mapei user. It hold the joints well and dries quickly certainly worth trying and cheaper than BAL.
Only commenting on the tiles today [being metro] Found the Rubi groat float with the white rubber and dense foam far better than the Raimondi I normally use, just seemed to work better on these tiles.
