also if you have stored it in your van/car overnight and it has gotten frosty I was told it is no good
You can't add GT1 to MM2 in any case - it'll turn to chewing gum, not grout.
I lost a lot of silicone, add mix & primers a few years ago with the frost.
As whitebeam says you don't have to worry about powders, ready mixed left in the van will freeze..
