Mapei BuildFix Flexible Wall & Floor Grout Charcoal 2.5kg is rated 4.7 out of 5 by 29.
Rated 5 out of 5 by from Only choice for me I would only consider this grout. Follow the instructions and you can't go wrong. My advice would be to always wear a mask while mixing. The dust is extremely fine and will always get in your lungs.

Rated 5 out of 5 by from Great colour & product I used this with black tiles. I was going to use black grout but had run out. This looked like a great alternative,as it gives a contrast to the black tiles rather than black on black. Mixes well smooth consistency and goes on well. just remember to get plenty of wipes and a spreader / cleaner just for this colour as you will not be able to use it for any other colour after as it stains everything. I have a bucket of them for different colour grouts... Performs very well in wet areas too, kitchen splashback shower areas etc

Rated 4 out of 5 by from Easy to use, good colour Used on clay floor tiles in the new kitchen. Dries well & hard. Colour is good. Only thing is achieving the same consistency between mixes. dries quickly, so work in small batches.

Rated 5 out of 5 by from Finishing Touch... Brought this as I didn't get enough grout to begin with (it was a big room 36 sq m) and there was only a small patch left. This bag was enough without having too much to finish it off nicely. I always use this brand and will continue to as the overall finish is lovely.

Rated 5 out of 5 by from Great help from staff Was sent on an errand to purchase this by my contractor. We were uncertain about colour and in this regard a member of staff at The Highway branch helped me with a very good nature. Very grateful for that! Floor is all grouted now, and looks great! Thank you.

Rated 4 out of 5 by from Mapei quality but it's black! Can't fault Mapei grouts and adhesive, although I prefer the ultracolour grout. I have used other shades of grey Mapei grout before and they have turned out as expected. On the colour charts "charcoal grey" shows up as a dark grey. However, it comes out black by my eyes - bit disappointing.

Rated 5 out of 5 by from Great finish Overall very happy, easy to mix and work with. Don't leave it ready mixed especially if mixed a little thick as it dries and hardens rather quick. Can't fault it, good fitting rubber gloves are a must as it gets behind nails and around them and while it's easy washable from skin the nails will show it. Only suggestion for those looking for a dark grey but not black is that maybe its good to experiment with black and charcoal as this is the darkest of all grey but when completely dry it is more into ash grey which is even more highlighted with my dark slate tiles. Cleaning off after grouting was extremely easy on the high gloss tiles. Wiped the excess and after 10mins or so went back to give it another light sweep with a dry cloth to get the surface clean.
