I am starting to wrap my metal building. Sheets come together on the corners, and I will use 6" x 6" x 10' 90 degree 26 ga, paintlock flashings. In some places, it will be advantageous to add a caulk of some form, but for larger spaces than a normal caulk bead.
Can I use a string of Good Stuff, and just let it expand? Will it adhere to just the flat surfaces in the 90? If you use it to fill up the ridges on the corrugated sheets, would one just spray a little in there, let it expand, spray a little more until it filled the area?
What I want is to cut down on air flow/infiltration/outflow so that inside air stays in, and outside stays out, and there aren't a lot of drafts. Other areas around the doors will be handled with bulb gaskets, etc.
Just wondering how that stuff works in other than voids where it expands to fill the void. Does it stick when applied overhead, or on a vertical surface? I may have to make cardboard dams to stop a lot flowing out before it hardens and skins over.
Anyone ever use this stuff in that application, or have an alternative?
