What colour grout?
You should only have to regrout the shower. The rest doesn't get wet.

Topps have taken photos and samples for BAL. I am expecting a call from BAL for their own visit. The implication of what I am hearing so far is that I have not followed the manufacturer instructions for mixing: "Slowly add approximately 5 parts powder to 1 part clean cold water by weight". Am I being told I should weigh it out? I have been mixing for years and surely the texture you want to achieve becomes second nature. They are saying Micromax must be mixed in that particular ratio. I will wait to hear the test results and what the local BAL technician has to say. But I feel I am wasting my time and should just get on with weighing out my new mix for re-grouting!

Maybe you should weigh and see if you get same prob

Good idea! Yesterday BAL told me to mix a small amount on to a scrap tile which I did. This morning when Topps visited, the grout softened when made wet just like the grout lines.
So I pinched the wife's scales, put on a small mixing bowl and set the scales to 0. I added 4 grams cold water, then grout to take it up to 24 grams so 4 grams water 20 grams grout 5:1 ratio. I have put the mix thinly next to the first sample. It will be interesting to see what it is like tomorrow.
Does anybody mix grout this accurately?

jon hey, do not go into paranoia, you did nothing wrong, from what I understand.
I've always done grouting, as I like it, hard or liquid. only changes the color.
whether they indemnify, okay.
or, the negative publicity has already been made here.
