I have decided to make custom 48″ x 72″ single-layer wood panels. I plan to use a 1/4″ plywood or MDF panel over a 2″ plywood cradle with cross struts every 24″ with corner bracing. Is there an archival preference for plywood or MDF? Could you would recommend a wood variety or brand of MFD? Are plywood cradle struts better than a solid wood cradle, such as poplar? I will apply two (2) coats of Acrylic Gel Medium. I will then apply 1/4″ to 1/2″ of textured modeling paste before I apply acrylic paints. Are there any issues I should consider with very thick modeling paste, such a reinforcement? thanks
1/4″ plywood seems pretty thin for a panel of those dimensions. I understand there is a big advantage in lighter weight compared to fiberboard, but I would be concerned that the cross braces might be visible through the front of the panel. If you are limiting options to common construction panel materials, have you considered thicker MDO plywood instead?
It is generally preferable to continue on the same thread. I am assuming that you sre contiuing from a previous thread which cn be foundhere. I hope the info is of help.
