I left my tub outside and hadn't put the lid back on properly, and found water on top of what was left in the tub, and poured it out into a tub to put into the bin to be incinerated, and hopefully stirred it to see if I'd end up with a filler which is thinner and more liquid but still usable.
Is it screwed and should I just make use of the handy tub for screws and nails, or can it still be used for anything where it can be spread thinly and given more chance to dry and cure?
I'm off near Wickes soon and could make the most of going in that direction to buy some more...
