Hi,

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,

Sam

the surface has to be primed
too much moisture in plywood

A hunk of thick styrofoam, like for foundations, won't work?

If you want to rig something up, waxed paper might be your friend. Not too
much sticks to it with any strength.

Or, just tack/staple a piece of cardboard under the bottom of the roof
joist/rafters. Lots of scrap cardboard available.

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?

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!

I'm trying to insulate a small patch from cold.

Probably much easer to glue a piece of foam to the ceiling. cut to size,
use white glue and/or a mechanical fastener.

Couple layers of corrugated cardboard, and some drywall
screws with washers. Much cheaper, and works about as well.

Or fasten the foam up with the "great stuff". It makes a very good
foam adhesive spray some on the foam, slap it up and tack a strip
across between the rafters to hold it up intill the great stuff sets.
