Matting, Framing, and Glazing
Sizes and Adhesives
Hello, I want to glaze (plexiglas) my paintings. What kind of rigid panel should I attach the canvas to that doesn't hold too much moisture beneath the finished painting? Hardboard is heavy and can warp. ACM can be expensive or tricky to glue canvas to. Does glueing the linen to the support using acrylic medium attract extra moisture? Will framing behind glazing restrict the oxidisation of the paint? How much space is needed between the glazing and the painting and a rear board?

Just to clarify, it sounds as if you want to try and adhere your completed painting to a rigid support, something that can be risky to perform. I would worry about attempting such an operation far more than interfering with paint oxidation and/or creating a potential moisture barrier via glazing. If you are attempting to do so we can do our best to give advice regarding this process but in general we do not recommend doing this. As for glazing interfering with paint oxidation I would not be too concerned about this. The paint will dry no matter what albeit somewhat slower if it is truly sealed (you would be surprised...simply placing plexi over the surface does not by itself prevent airflow). Every great once in awhile we see a slight haze begin to accumulate on the reverse of the glazing (plexi side facing the painting). This hazy film has been tested and found to be free fatty acids re-depositing from the paint film onto the glazing. This can simply be addressed by occasionally removing the glazing and giving a good clean. I would also not be concerned about glazing potentially causing a buildup of moisture (and no, acrylic gel medium/adhesive will not cause a problem here) as again there will be a slight airflow unlesss you have a professional framer create a sealed climate package (as is sometimes done for paintings in museum collections). We can reach out to our resident framing experts on this one as I may be missing something.
EditDeleteModerator AnswerYes...having someone use a heated vacuum table to attach a completed painting onto a rigid support is what we recommend. You can ask your framer to do it (if they have such a device) or your local conservator.
