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.

Which colour is darker?

I am looking at Anthracite (114), and Charcoal (47) - both by Mapei - and have both bags sitting next to me. The colour sticker for both looks identical - is it possible to confirm whether these are in fact the same, or what the differences are please?
Asked by: RB1080
The colour between Mapei Builfix Flexible Wall & Floor Grout Charcoal & Mapei Ultracolour Plus Anthracite are similar however from knowledge and past experience the final produced colour can be influenced by many factors, including mixing, water content, rate of drying, etc. therefore coloured samples should be perceived as a guide only as to the likely final colour.

Any info on coverage per 2.5kg bag?

Asked by: DanDaisy
The consumption of the grout will be dependent on the size, thickness of the tiles and the width of the grout joint used. To give a general idea of coverage for a tile that is 300x300x8mm with a grout joint size of 3mm the coverage would be approximately 8 square meters for the 2.5kg bag. Further coverage guidelines are available on the packaging of the product.
