Along with the following post, I have a styrafoam building which has had some details knocked off and broken. They can be glued back on and/or repaired, but what kind of glue to use. I did not originally build this and have no idea what type of glue to use. It is an outside building so weather is a factor. Anyone have any suggestions? Something that will not melt the styrafoam.

White glue for indoors and "yellow" glue for outdoors. Also use only water-based paints.

Liquid Nails also has a special "Liquid Nails for Foam Board" that you can usually find in squeeze tubes. I have also used Loctite PowerGrab (which is water based) with good results.

I just used Liquid nails construction adhesive to make some coal loads for my hopper cars. Worked fine on the blue styrafoam. I did paint it first tho with some latex paint.

I also use liquid nail in the small tube for small blue foam jobs and in the caulking size for big jobs.

Thanks guys, I'll give the liquid nails a try. Never tried it before, so this will be a first for me.

For Styrofoam I usually recommend 3M Fastbond Contact Cement. It is water based so it does not attack and melt the Styrofoam. You brush it on and let it dry, takes longer than solvent based contact cements, and press the parts together. Most other glues that are air dry will stay liquid in the middle since no air can reach the glue through the Styrofoam.
You can read about the Contact Cement here: http://www.tapplastics.com/shop/product.php?pid=271&

Thanks Russ, but I'm afraid that is a little too rich for my pocket book and I sure don't need a quart of it. I have just a few repairs to make. I do appreciate your response though.

Greg,
That's what I figured, but I thought I'd put the information out for anyone that has to do a lot of Styrofoam Laminations.
