Is it possible to fix a bad seal on a humidor? I tried the dollar bill test because I can't find a flashlight that will fit inside. All I have is a mag lite. I am not sure what the dollar bill proves. It didn't just slip right out but it wasn't hard to remove. I am borrowing my dads mini mag lite tomorrow so well see, but if it does have a bad seal am I out a 140 dollar humidor?
Yes, I made a gasket out of GE Bathtub caulk for my first humi.
Here's how I did it:
Build up some masking tape around the lip about 1/16"-1/8" high,
leaving a gap that the caulk will fill in. Cut strips of waxed paper.
Shoot some caulk into the gap, put strips of waxed paper over
the caulk and close the lid of the humi. Let it cure for a couple
of days, maybe a week. After it cures, open the lid, peel off the
waxed paper and masking tape, and you'll find a tight seal.
Trim as you see fit.
Another way to make a gasket is to shoot the caulk on some
waxed paper in approx. the same dimension as the lip on your humi.
Use some coins or toothpicks as spacers.
Place another piece of waxed paper on top, then put a book
over that, which will flatten the caulk to the height of
the spacers. Let it cure and then you can cut pieces of
cured caulk to fit along the lip of your humi. Use a very
thin bead of caulk to secure the pieces of gasket.
I used the alcohol based GE Bathtub Caulk II, rather than the acetic
acid based caulk, just for less odor.(I didn't want a vinegar(acid)
smell in my new humi)
If you want a little air circulation thru the humi, you can trim a few
small gaps in the gasket.
My humi seals tight and holds rh for a week+ without adding water to the beads.
Mine has some air circulation, since I did NOT seal around the window in my lid.
And it smells GREAT, when I open the lid! Mmmmmmmm... tasty!
