some advice please

so i just bought my first house and im noticing that the garage which has already been drywalled has some spots only on the bottom of the walls that are shriveled up like it was wet then dryed. now the drywall in some area's are still damp to touch but only on the inside(if you feel from the bottom, and the paper backing once you take it off) but it seems like it is only in area's where the drywall went below the framing and touched the concrete footing. It is not actually touching the floor just about 3-4 inches from the floor where the concrete footing starts. Now other than the obvious such as a leaking roof, can it be getting damp just from the cold concrete. I live in a very cold part of canada so the wether is not alway ideal....

thanks

Any time you have the drywall close to a garage floor there is potential for it to get wet. I would cut the drywall up high enough to slip a 1x4 exterior trim board under it. This would get it away from the damp concrete.

thanks for the advice.... i think i will do that. aslo what kind of caulking would you use for that job?

also why would you use 1" thick when the drywall is only .50" thick?

Just about any good quality paintable exterior caulking should work. I would stay away from silicone caulking.

To look like a finished trim board it should stick out past the drywall. A 1"x4" board actually is 3/4" thick bringing it 1/4" past the drywall. My trim is 3/4 past the drywall. see the picture below....

As a side note: You might notice that the foundation wall is 18" high in my shop. The purpose was to keep the drywall away from the floor so that I didn't have to worry about the drywall ever getting wet.

Nice planning on your part mine on top of a four inch curb now it's decent however it still get wet a little when I choose to wash out the floor.

I would try to find a vinyl trim product. Then you won't have to worry about wood getting wet either. Put something weather proof down there.
