Polyester or linen, what is the most archival surface to paint on?

The long and the short of it is that weight is a consideration for large panels. In fact, stretching canvas over light-weight chassis is the solution. As for materials, fiberboards (including masonite and MDF) lack the structural integrity of natural wood, and deform of their own weight. Applying canvas over such panels doesn't eliminate the problem of movment of the supports under brittle paint films. New-fangled panels such as cellular resin-core aluminum laminates are quite durable, light and rigid, but the problem of adhering the canvas remains, with the attendant criticism that these materials and processes have not stood the test of time as traditional materials and methods have.

The hand-wringing over these details is certainly a major problem for those artists painting today whose work is assured of being timelessly important and treasured in the next century and beyond. Perhaps they should work in buon fresco? Oh! what if the plaster cracks, or the walls behind it crumble? Heavens! The agonies of worry!

Richard,
I don't exclude any type of supports and think that the choice should depend of the size of the painting. Small ones could be glued to MDF or Masonite, bigger could be on cradled Birch Plywood and the large portraits could be on Honeycomb Aluminum.
I don't think that the gluing would cause a problem either, I would use a water based glue meant for flooring such as Linoleum.
Would that function?

Moderator's Note: please keep this thread on topic (archival surfaces and substrates) and discuss glues on a glue thread so that artists (like me) with perennial glue questions wil know where to look in the future.

Linda, I removed the "sticky" comment. Is there a thread or section on glues? (discussions of painting supports often wander into digressions on glues as sizing, and methods of adhering fabric to panel)

One of the plusses of this site is being able to find things!

Trolling for something else, I discovered this brief thread on topic, adding a couple of other voices.

Richard,

Here are some folks talking about adhesive applications, from about 5 years ago . . .

Thanks much, Steven!

(I realize that similar questions and discussions seem to "recycle" over time . . . that probably becomes boring for those who have already been there, done that and bought the tee-shirt. In this case, it's well to revisit the older threads, because of the reference to Studio Materials. Alas, Mike Ozog threw in the towel on that enterprise a couple of years ago.)
