   PL300, maybe FRP trowelable mastic. You'd have to read the can.

   You want to use a Pannel adhesive.

   Check the labels most of them can be used on foam. Using it right now to attach the foam to concrete walls. Forgot the brand, but but remember the purple color of the tube.

   "I'm looking for an adhesive to bond 1/8 or 1/4 inch ply to 2" rigid foam insulation. I will be using a vacuum press so clamp pressure will not be a problem. Any suggestions?"

   What is the application?  That 3M #77 spray-on contact cement works real well for light duty stuff, and is a breeze to use.  Many other products out there also that would work if greater strength is required.

   The application is a knock down spray booth. The idea is to have lightweight 4x8 panels that are easy to set up and store, but are durable enough to last years. Basically a small SIP.  Tom

   Is the pl 300 trowelable? The latex frp mastic looks like it may be the way to go. Any idea about coverage per gallon and clamp times? I have never used eithr product   Tom

   Never tried to trowel the 300. It comes in quart caulk tubes. A little goes a long ways. The latex base FRB - a hundred feet or so to the gallon with a 1/4" notched trowel Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming....                                        WOW!!!   What a Ride!

   I have a cheap shower to install. One with the plastic pannels that go over drywall.

   The instruction say to use the cartridge surround adhesive and then use a notched trowel to spread it out.

   Bill,

   You did mean shower?

   I actually have used contact cement to put those up with very good results. But you DEFINITELY need an assistant.  No wiggly room, and it has to go up just right the first time.

   I prefer the FRP mastic for that work. It grabs and holds. Easier than than the tubed stuff. Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming....                                        WOW!!!   What a Ride!

   Tom,

   I have never tested or tried this, but If it were me.....I'd see if polyester resin would work.  It's cheap ($25.00/gallon), Doesn't need air to cure, and assuming it bonds to the foam (I can't see why it wouldn't), and is plenty strong.

   One caveat, make sure you cover both sides to control warpage, as it shrinks slightly over time.

   Also, why not use tin coated  or galvanized steel sheet instead of wood?  It would probably cost the same and be lighter and stronger.

   "Mostly cause I don't really like working with metal."

   Tom,

   Sheet stock is not all that hard to work with, How come you don't like to work with it?

    All you really need is a couple pair of DECENT tin snips, though an air powered nibbler is nice too.

   FWI,  I sprayed a piece of foam (extruded polystyrene) to a piece of flat ductwork I had lying around with 3M #77, just out of curiosity.  One heck of a bond.

   It's not that I don't know how to work with it. I just prefer wood. I do enough metalwork at work. Tom

   And what is the purpose of the foam?  What will you be doing with your spray booth?

   TomMGTC | Mar 26, 2004 10:21pm | #16

   Furniture finishing and maybe a car project or two. The foam is part of the wall structure. Lightweight, yet rigid, consistant in thickness, minimal framing needed.      Tom

   Describe your spray equipment, if you have the time.  I am considering some.

   Nothing special really. I have a two stage turbine (apollo spray??) with an accuspray hvlp gun and I also have a porter cable conversion hvlp gun. Also a couple of cheapo standard guns I use for spraying dyes from time to time.   Tom
