Got given a couple of buckets to try and report back. Ready mixed grout that behaves like UC+ without the hassle. I found this product on google a few months back and realised it was not a DIY type crappy grout and it's been about for years in the US. CTD are trialling 3 colours and giving it to regulars to try out and report back. If they get enough interest they will buy all the colours in bulk to pass on a good price to traders.
