[SEL] Condensation problem in shop

[Larry Anger]

George - The workshop part of my barn is well insulated and I heat it with a
wood stove most of the time and I do have a radiant gas heater if I want to
keep it heated when away. I find that this part of my barn is worse for
condensation than the rest of my barn. If the shop is left unheated and then
the weather warms up dramatically all my machine tools will be covered in
water as well as the concrete floor. I have exactly the same situation as
you, high humidity and drastic changes in temperature. I have a special
spray on moisture barrier that hardens up somewhat like very thick grease
that I spay on all the machined surfaces of my vertical mill and lathe and
keep them covered with this stuff at all times when I'm not using them.
Other than using heat and dehumidifiers there is not much else you can do. I
find the concrete floor the biggest problem.

I have concrete floors and somewhat insulated walls in my main shop area.

But it is an unheated building 99% of the time.

Around our parts the roof needs to be insulated, even if it's just the 1/4"
of bubble wrap looking stuff.  The other thing is to install a vapor barrier
under the floor.
