   I think that it is PL 200.  They make one that is specifically for gluing foam.

   How about the cans of expanding foam? Glue foam with foam.

   Way more expensive.

   The stuff to use is PL 300, IIRC. Cost about 1/3 as much as a can of foam.

   That said, if somebody needs to seal the edge of a foam panel to, say, the rafters or joists in a bay, 1-part foam is the way to go. But Dave just needs to stick the panels in place, I think.

   Thanks.

   Must have used the wrong Pl# when I made up the props for the high school marching band. I glued 2" foam board to some 1x s and the glue melted the foam. Glad I had backed it up with screws and fender washers. I would have been embarrassed as hell if the props had totally fallen apart durring thier first competition.

   I just need to stick some 1" board up inside my foundation wall before I have the rock slinger  come in to place the crushed stone. If I were placing the rock  with my tractor and hand grading I would bother with the glue. Shooting the stone in with equipment is a little tougher to keep the board in place.

   Since I'm not going to be on site when the work is done, I leave as little to chance as posssible.

   I just checked; LePage's brand of foamboard adhesive is indeed PL300. It's labelled in large letters "Foamboard".

   I did a similar job in an old cinderblock basement a few years ago; shooting in 15T of gravel through a window and the whole megilla. Damned cinderblocks were so old and uneven that even the PL 300 had trouble holding the foamboard in place. I wound up strapping them with 1x3 and Tapcons.

   If you're just tacking it up, I've used some foamboard stuff from Lowe's that is 1/2 the price of PL. Circles of either adhesive seem to hold better than squiggles or dots.I have had no luck with Power Grab working on foam and block or poured concrete.http://www.tvwsolar.com

   Thanks, I'll look for it.

   Cheap is good.

   Stone will hold it in place after words. I just need it to stay put while they shoot the crushed stone in.

    Going to be a liitle over 100 tons of #9 crushed limestone going in.

   Maybe I'm wrong, but I recall "blue board" as being an alternative to gypsum wall board for rooms that have moisture, like bathrooms. It's not a foam. Which are we talking about?

   Reginal thing.

   We call Dow rigid foamboard "blue board"

   More manly than saying pink board, even when we do use it :)
