5-45 is through the course of the year though of course, not over days/weeks. 5 on winter mornings, 45 on summer days. Never a swing from one extreme to the other.

Not relevant to the powder & primers but if it has a concrete floor was the floor laid with a moisture barrier underneath the concrete (plastic seal) as most outside unexperienced builders do not do this and hence the concrete will absorbe and excrete moisture, especially anything sitting on top unprotected. This at times will explode the humidity content inside. The only way to fix that afterwards is to seal the surface of the concrete with the likes of epoxy resin.
It's just a run of the mill shed... 3m square floor, 2.4m high roof sounds about right. I'm not a builder but the way the floor to me looks like there was a metal tray which they filled with concrete. The floor is 3" thick and sitting on earth.
Don't know if the floor is sealed with anything... All I can say is that on my casual observations it moisture doesn't seem to be a problem.
Apollo wrote:If the shed is reasonably high, like 2.4m or so then I would suggest heat treating the whole shed, walls and roof with insulation plus an internal lining and/or a false ceiling. Going overboard.... yes, but I would not store components in my shed if it wasn't correctly built.
The time/expense isn't going to be worth it for me to do all that...
Not a big deal though, if it's not suitable to store the stuff out there then that's my answer so it's all good.
I'll still be setting up the man cave in their, I'll just have to store my combustibles inside.
Thanks for all for replies, especially Apollo.
