Rated 2 out of 5 by Grout expectations! Not too impressed. Goes off too quickly (as stated by others) so either takes longer to do the job, as you have to keep mixing smaller batches, or you rush the job (with potential for an unsightly finish) and / or waste / bin some of what you mixed! 7mm joints on porcelain tiles (so shouldn't have required pre-moistening) but although 'worked' finish is acceptable, have noticed small cracks in several areas, which would obviously be unacceptable in (for example) a wet room! Also applying to floor with White tiled walls down to the floor to perimeter & didn't think to mask-up before applying floor grout. Result - badly discoloured white grout at base of wall tiles (my fault really, but worth pointing out for others!). Will avoid this brand in future! 11 Jun 2016
Rated 4 out of 5 by Quality product I tend to think Mapei has the edge on the other manufacturers of grout and adhesive for tiles, but I agree that it could do with a bit more time before it goes 'off'. Maybe a bit tedious to clean up after, but most grout is the same. Good product. 8 Jun 2016
Rated 5 out of 5 by excellent Excellent quality product, consistent and easy to mix, with a good colour tone, but I would agree with other reviewers, it goes off very quickly, probably too quickly for application on a hot day. I used it on en-suite walls, with gloss white beveled metro tiles and am very happy with the contrast of the grey against the gloss white of the tiles. Beveled tiles are a pain to float (as they are not flat like most tiles), so when using this product i had to make up small 1kg batches at a time, and only just used each batch up before it started turning. 9 Aug 2015
Rated 5 out of 5 by Excellent product Did a bit of research on what grout to use in my kitchen,chose this one. powder mix seems the way to go and it mixed well. It does start going off after 15 mins so mixed 1kg at a time with 200ml of water which covered 2m x 1m. Goes on really well and dries a nice mid grey with no shrinkage and really hard.Really pleased I used this and would thoroughly recommend it. Excellent product. 13 Mar 2015
