There are lots and lots of posts online about PMF on foam.
I have done the inside completely and will be shortly working on the outside.
I'm wondering if you have particulars about materials and methods. Everyone seems to have their own take on what works best.
I have read lots on the TNTT site regarding multiple tests that everyone has tried.
I am using 2" XPS and 8-10 oz canvas. I don't have access to glidden gripper in Canada.
I guess my biggest question is....What is the pre treatment on the foam to make the canvas adhere best.
On the inside of my trailer pockmarked the foam, then sanded the foam then used Bullseye 123 primer and then did a 50-50 TB II glue to water split to adhere the canvas. I then painted it multiple times, thoroughly soaking the weave. I find that although it works I would hope that there might be something that might stick better to the foam.
I have read that the canvas acts like a sock and doesn't stick the best but surely there must be some method that sticks relatively well.
I'm hoping I can get a definite answer on this in order to decide a direction to go next.
I know this has been asked many times but would like some more input.
Thanks in advance.
