What's the best trick making Great Stuff stick to the bottom of the roof
and not fall prior to curing?
I have an area that's about 18" x 18" that needs to be covered. The
bottom of the roof is plywood.
Thanks in advance,
Gorilla Glue is the same basic stuff as Great Stuff... and I ~think~
you should be able to apply some Goriila Glue (or another brand of
polyurethane glue) with a notched spreader (like maybe an old credit
card... use some scissors to make some notches)
Leave this sit for a bit (an hour? a half day?) and then the Great
Stuff should stick just fine.
IF there really is moisture in the plywood, this is a bonus, as
applying polyurethane glue instructions say to spritz the wood with a
little water before applying the glue. The moisture soaks into the
wood a bit, carrying some of the glue with it.
This is just my hare-brain, but I think it would work nicely for
confident results and not a whole lot of pain.
Best of luck!
Why have you chosen Great Stuff? It's designed for filling
cracks, not sticking to a ceiling. Tell us, please, what
task you are trying to accomplish. Are you doing sound
deadening? Just like the yellow color? What?
