Home Forums Supports Tempered Hardboard

    Tempered Hardboard was presented as a substrate in the Webinar. I was thinking of using it for linen covered panels with a shellac based primer on the back and sides. I would probably keep them in the 12”x 16” and smaller range to prevent warping, and use MDO for larger pieces.

    Would there be drawbacks to using tempered hardboard this way?

    I’m replying to myself… I was able to find the section that addressed this in the webinar. It was fully explained.
