If you are grabbing a free edge of canvas and pulling it up in a peeling action, then yes, it might seem like it is easy to pull it up; but if you try to shear the joint by pulling the canvas parallel to the glue joint, or bend the foam and the canvas doesn't delaminate, then you are seeing what should be expected.
When you peeled the canvas up was there a very thin film of foam stuck to the back of it, almost like a peach fuzz? If so that is the foam failing before the glue, and that's all you can expect. The strength of the panels comes from the tensile strength of the canvas in the direction of the threads as stabilized by the foam, not the tensile strength of the glue joint.
Thanks for replying so soon. Its more random small chunks of foam that are sticking to the canvass. Theres a lot of them but its not like a film for sure. Its probably doing what its supposed to now that i look at it again.
I went to a whole bunch of stores just now looking for paint and couldnt find glidden gripper. However i called home and got my wife to look at the rest of the paint and realized i bought 5 gallons of armor coat porch and floor paint acrylic latex satin and 1 gallon of alkyd gloss enamel. Of course i took the alkyed for the test pieces

Whats the general concensus on the benefit of rolling a thinned layer of tb2 on top of the canvass before paint for added strength? I saw some people had done it here so i did a test piece but the paint softened the glue and melted the foam...does it make it stronger or more mould resistant or waterproof?
Thanks
