"Mixes easily and sets at a very convenient rate. A very sensible pack size - small enough to be reasonably priced for small jobs, big enough to cover a decent area. The unit price is around or below comparable products in much larger packs, so a very economical purchase. Packed internally in two plastic bags. I found the roughly 3:1 mixing ratio recommended too sloppy and used almost 4:1 powder to water by weight. Dries and wipes away from the surface in minutes, while giving you over hour to work with, so very easy to apply. It does crack in very wide gaps, but most people will find this an ideal product for floor grouting."
"This stuff was fairly easy to mix and use but has started to crack after being down a week in a new bathroom refit. Gaps were not overly big (5mm) so not sure if it's a bad batch or if it's not truly flexible."
