will tuck tape stick
I have a section between my wall and stair stringers where the best I can do is tapcon up pt 1 X 4s every 24 inches (on center) directly to the concrete wall and put DOW 1/2" blue board in between. I can then squeeze 3/8" drywall overtop. Should I tuck tape where the DOW XPS buts up against the pt 1 X 4s? Is that overkill? Will the tuct tape even stick to the wood? Some other tape? No tape at all?
