Postby gill2161 » Tue Jan 14, 2020 7:26 am

i have been looking at posts where foam walls are covered with canvas and i saw a few that used titebond 2 wood glue to attach the canvas to the foam board but wont you need something over that like the stuff you use for fiberglass to make it solid?

After covering, the canvas is painted with several coats of house paint. That seals the canvas and makes it waterproof. The skin is not hard which is a good thing; it's not brittle. Small dents are self healing in the sun.

Like taking a tour of NASA and asking if it really is possible for humans to go to the moon and back.

fiberglass uses epoxy to make it solid. With Poor Man's Fiberglass, aka PMF, we're not looking to make it solid. The foam is the solid part. The glue, canvas, and paint make is stronger and more rigid. We usually do put the foam inside a wooden frame so we can attach one piece of foam to another by screws and glue.

I always suggest that before you go out and buy a trailer and hundreds of dollars in materials, you start small and do some experiments with foam and canvas to find a combination that you can work with.

Have fun

John:

I didn't respond to this post because I don't have any personal knowledge of PFM. He's asking for help.

Gil , Welcome to the Foamie Forum !!! What you suggest , works GREAT !!! It’s been many years now and all is well proven …

From experience , PMF ( Canvas over Foam) works great adhered with T2 or similar glue .. Some Acrylic primers also work … although I believe the best of them (Glidden Gripper) is not the same ... best check here for latest product comparisons ;)

Just be assured , whatever you do , there will be Plenty of Help available here !!! :D Any question is a good question !!!
There’s no place like Foam !
