    Question

    ​Hello,

    Recommended practice is to not glue cross braces to the back of a (let us say, 1/4 inch tempered hardboard, or 1/2 to 3/4 inch Medex (minimum formaldehyde MDF panels).  Considering medium large, 36 by 48 inch panels, or similar.

    I assume/ have read that the reason is to minimize or eliminate the bracing  "marks" appearing in the painting over time, and the potential warpage these wood strips may undergo.

    How can the cross bracing perform its intended function of keeping the panel from "cupping" or "bowing", when it is only attached to perimeter bracing?

    Has the website ever considered a "visual database" of contemprary "best practice" supports?  For example, every internet search for building a wood panel for painting recommends glueing cross braces to the back of the panel, which is, probably, bad.  But not doing so  may lead to "warping, bowing, cupping"; also bad.

    Pictures would be helpful.  Thank you for considering questions that are more implicit than explicit, and many thanks for your time and effort considering these issues.

    You are correct; we want to avoid creating the appearance of undulations associated with the bracing overtime. I have found that if you use a hardwood like poplar or oak for the crossbrace and secure it to the outside members using “L” brackets and screws, the bracing provides support without gluing it to the panel.
