Thanks for pointing out the problems with ready mix. I now realise its got serious limitations. I'll use the Ardex X7.

Not very interesting reading but it appears Chromium VI is a skin irritant that leads to eczema and dermatitis. By adding a compound to cement the chromium VI is neutralised when water is added, but the neutralising agent degrades in some way over time. This is why use by dates for cement based products are not as long as they used to be.
Yawn!
