Hello Mitra,
I know the old masters used solid poplar and oak wood panels that were dried heavily in order to avoid warping and having the acids rise to the surface. Obviously they also sealed them in order to have extra layers of protection.
Now a days with ovens that dry the wood, and things like plywood and mdf like wood, im curious to know if we have to worry about the acids rising to the surface and about the warping? Technically plywood warps less and mdf if sealed doesnt absorb moisture and shouldnt warp. I dont know about the acids in the mdf and if they are problem.
Are plywood and mdf panels suitable for painting? Should artists just stick to solid wood? Are MDF boards and plywoods even archival?
Hi
We have prepared a rather comprehensive document on this and related subjects. Rather than rewording it here I suggest that you read through a few downloadable pdf found below and then return to ask anything that we did not cover. I suggest that you read the pdf on “Rigid Supports” first and then “Adhesives and Sizes” and then “Grounds and Primers”
