The angled galvanized sheet is to bond to the foam with Gorilla Glue. The inside of the wall is to be captured by the 1"x1 1/2" spruce. After primed the canvas is to be glued on using Titebond II.
Do I need to saturate the canvas all the way through with the glue or just glue it on and after dry soak paint into the canvas? Was thinking of slightly watered primer (depending on if it soaks in well) then a top coat of paint.
I plan on doing a test run on some material but thought I would ask first to gather the wealth of wisdom from others.
While I am here, might as well ask, I need to bond the insulation sheets together. Do I use Gorilla glue or Great Stuff, foaming both surfaces and once it bubbles up squeeze them together?
There are a number of right ways to do this and a whole lotta wrong ways. I'll make some suggestions...
- Add a cleat (3/4" solid lumber) glued into the edge of your wall for anchoring the wall to the floor. You can use Great Stuff, Gorilla Glue, PL Premium, your choice of glue. For making the kerf in the end of the foam research hot wire cutters or use a router (dusty).
- Scrap the galvanized metal and wrap your wall canvas down and around the skirt (which I would do with a solid piece of lumber rather than foam). Then screws can be driven up underneath into the skirt, through the floor and into the cleat in the wall. Maybe every foot or so.
- Canvas your wall horizontally on a bench if possible leaving more than enough to wrap under that skirt. Your canvas will shrink so allow for an extra inch or more over what you will wrap under. Yeah it'll have some dried glue on it but when you go to install the wall it will still flex around the floor easily with a little heat applied with an iron.
- Before gluing the canvas on score the foam with something so the TBII can get a good grip. I used an old wire brush at random angles to scratch the surface.
- Apply a generous coat of thinned TBII, place the canvas on the foam and brush smooth with a wallpaper brush, broom or wide paint brush. Then lay on another coat of thinned TBII to saturate the canvas. When that has begun to dry add another coat or two.
- The 1 x 1 1/2 spruce is a good idea to help secure the wall.
- Add a drip edge to the skirt.
