Has any one used Gorilla glue to glue down foam to hermosat board or is there something better to use.
I'd like to say in the past year...Model Railroader did a review (sorta) of various bonds/ahesives and glues...and they didn't rate Gorilla Glue very high for that purpose (IIRC). Does someone with the mag handy ?
It is to be used with woodland scenic foam risers. And also if it works with pink foam for some cliffs and hills
Well I guess it could work if you were going to cover over the joint with plaster cloth and other scenic material. Yeah it expands and foams and oozes out all over the place so you have to deal with that.
Be certain to use something that won't attack foam. Such as Liquid Nails "Projects and Foamboard." Which is what I have on hand. Boxcab E50
I use Liquid Nails - Projects (Foam) for most everything. It bonds foam board to wood risers, layers of foam together, cork roadbed to foam, and track to cork. For track to cork, I use my finger to smear the LN to a very thin layer over the cork, then just push the pre-formed section of flex track onto the smear and squiggle into place...no fuss, no mess, and no oozing between the ties. You have up to 1/2 hour of work time. Might have to lay some pieces of wood on top for weight. After 12-24 hours the LN has set and the track isn't going anywhere. AND this type of Liquid Nails cleans up with water....a MAJOR Plus! To remove the track from the cork, insert a putty knife or old carving knife between the track and cork, then slide it along the track....it just pops up.
I used Liquid Nails for Projects to attach my foam to 1X3 pine board. I used Elaine's Tacky Glue to attach the cork roadbed and WS risers to the foam and my track to the cork. I found Elaine's Tacky Glue easier to work with than the Liquid Nails. Elaine's Tacky Glue is similar to Elmer's Glue. I think Liquid Nails will give you a stronger bond however. Be careful when buying Liquid Nails. They have two types, one of them will eat foam. You want to get the one labeled "for projects". The label will say it is safe for foam.
Actually, that's Aleene's Original Tacky Glue, according to the bottle sitting 8 inches from my right elbow at the moment. Gorilla Glue, or any other polyureathane glue, may be problematic for foam to wood. A simple white or yellow glue, or a latex caulk would probably be better.
I've tried tacky glue for my black foam woodland scenics roadbed to my pink foam base, but it took forever to dry and didn't hold the foam too well. I think it's made for porous materials, not closed cell foam. The absolute best stuff I've found for foam by far, much better than liquid nails is a polyurethane based construction adhesive. The brand is pretty generic but it's called "PL polyurethane premium construction adhesive" and runs about $3.50 per caulking gun tube at the builders supply where I get the pink foam. It doesn't melt the foam at all (liquid nails does melt it a little) and it holds stronger than any liquid nails type adhesive I've ever tried (and I've tried a few). So yeah, for foam I'd recommend this product, the PL polyurethane premium construction adhesive. It basically looks like liquid nails (tan color, comes in a caulk tube) but is not harmful to the foam, not full of solvents and doesn't stink up the place, etc. Any polyurethane based adhesive should act the same.
Thanks for the correction. I'm at work so my bottle is about 1,774,080 inches away from my right elbow, give or take an inch or two. I'm not exactly sure where I left it on my workbench or I would be more precise.
Let me throw in a bit of Liquid Nails experience here.... Liquid Nails for Projects (Foam) is easily worked and is water clean up, even from fingers, cork, and flex-track ties. I ran out of LN one afternoon and went to a local building supply store where I was assured that the Dow (DAP) product they sold was INDENTICAL(!) to the Liquid Nails for Projects (Foam) product....W R O N G !!!! 1 - Dap cleaned up with Mineral Spirits ONLY! 2 - Dap attacked the foam! (OK, just slightly, but it did attack) 3 - DAP did not smear or smooth out like LN Projects! I swear by Liquid Nails for Projects (FOAM) for construction and track laying, but not for scenery.
