  • Repairing cracked masonite panelApproveRejectUn-ApproveSubscribeUn-Unsubscribe
    Question asked 2019-11-27 21:52:02 ... Most recent comment 2019-11-30 13:12:39
    Handling and Transportation

    ‚ÄčA fellow artist and I collaborated on a piece together, in both acrylic and oil paint on a 36"x48" cradled Gessobord. I applied ArtResin to the piece which was curing perfectly in the storage area on the third floor of an art gallery. I went up to the painting on the third day and found a couple of deep cracks had appeared in the glossy ArtResin. Upon closer inspection I realized the cracks in the resin were a symptom of cracks in the masonite panel. Since it was in perfect condition two days prior, and it wasn't subject to wild fluctuations in temperature, I assume it fell and someone righted it, not realizing it has suffered. 

    Now the other artist has been invited to ArtBasel and wants to take this piece. My question is; how can I repair the masonite so the end result is strong and also looks good enough should the piece sell?

    I think I have figured out how to repair the resin by sanding it down and reapplying it, but any suggestions for that part are also appreciated.

    Thanks in advance!

    Is the ArtResin on the presentation side working like a varnish? Hardboard is very difficult to repair satisfactorily. If the board itself will not be seen, this would be far more managable. Is the hardboard visible from the rpesentation side? The answers to these two question will have a major impact on how we respond.

    ‚ÄčThickness of the resin could also be a factor. Polyester resins formulated for poured coatings sometimes don't perform well in thick applications, because they generate more heat in curing than casting products. Excessive heat can lead to cracking from too-fast hardening.
