I got one of those boxes of joint compound, dumped it into a Homer bucket
and have been using it to do the mudding on my ever present drywall jobs.
I use a layer of water on top of it to keep it fresh, plus I also keep a
plastic cover over it to keep the buggies out and the cat hair out of it.

How long does it last if kept this way? I noticed once that a couple of
patches of green mold formed on the margins where the water wasn't totally
covering it. I wiped it away and recovered it and haven't seen any
return.

Should I toss it at this point, its about 2 months old, still handles like
joint compound and appears to do a perfectly fine job. Waste not want
t - ehh?
Hello,

As long as you keep a layer of water over it, It will last probably
over a year or so.......the green mould like substance was the water
evaporation residue from sitting without using.. If you dumped the film of
water every month or so and restirred the mud compound, then added the water
as a sealeant over top.....then you could make it last probably last
indefinately. Jim
