A little more about adhering canvas to panels
I returned home late last night after five days of driving. Long trip! A month on the road. I am reposting a comment from the blog as it is informative. Thanks Tim, for the method you use.
I was also asked this:
"Is the jury still out of polyester canvas? I have been trying it out and love that it is so stable and unaffected by water based primers and gessoes. It keeps its tension regardless of atmospheric conditions and eliminateds the need for keying. But I wonder about the paint canvas bond over time and what happens if the tension on the canvas is released. ? Will the canvas contract more than the paint film?"
I have decided that I didn't like the surface of the polyester canvas. It does stay stretched and is probably tough as nails, but it is a little like painting on a steel window screen. It has a very hard feel to it's weave in my opinion.
I wouldn't worry about the adhesion any more than any other acrylic primed canvas. Of course I always worry about adhesion on an acrylic canvas. The coming and going of the canvas should be less than almost any other canvas as the polyester is so inert, so that shouldn't be a problem.
For now I am using the Centurion oil primed linen from Jerry's. I think it is OK, but I haven't used it long enough to say I recommend it. Claussens type 12 is awfully nice but very expensive. All linen comes and goes a lot, that has been an ongoing problem for me, so I am not sure what I think is the best substrate. Up to 18by 24 I am happiest on an oil primed piece of Masonite. I wrote about how to make those in a blog post entitled "making panels.
I recommended Miracle Muck for adhering canvas to panels, here is an info sheet from its manufacturer on that stuff. They say that it is a EVA or ethylene vinyl acetate so it is PH neutral when dry and archival enough for our purposes. I still think that hide glue or Elmers is OK too, all the old guys used it and their work is fine.
Sourcetek, a fine supplier of artists panels and materials has an explanatory sheet on using Miracle Muck here. Here is a link to their site where you can buy excellent panels all covered in Claussens linen and ready to go.
I believe their site recommends using a rolling pin to smooth the canvas onto a panel and instead of beginning in the middle and working outward, they suggest rolling from the bottom. Everyone seems to have their own method here.
