Any thoughts on the pros and cons of 'mix your own' over ready mixed (or vice versa). I have always mixed my own but I am now thinking of changing to ready mixed so that the mix is uniform and consistent. Also when mixing grout the packet instructions never seem to be correct. The last lot I did last week said "3 to 4 parts grout to 1 part water by volume", even using the same measuring cup the grout would not mix to a useable consistency without adding more water. Keeping a careful eye on how much water I was adding, to get to a useable mix it was nearer 2 parts grout to 1 water.
Cheers
