I've just begun to gather materials needed for the 11' SUP. In searching for lauan underlayment for the spar and ribs all I can find is a 1/4" panel with a lauan face, hardwood veneer core, and a low density overlay on the back side. It is the LDO that I wonder about. Medium Density Overlay (MDO) panels can be used for outdoor projects without problems. Will the LDO be stable and water resistant enough for this project? Does it even need to be water resistant? I've only got about $11 invested in the panel so I can set it aside and keep looking if I have to. Thanks for any help you can offer.
Hi Rich, you might be already past this stage but if not I just use any decent quality ply I can find, can't comment on the MDO as I don't know it. As you were thinking hopefully no water is getting inside the board anyway but you could always put a sealer coat on as extra protection. Good luck with your build.
Blair, I went ahead, bought a sheet, and test glued a piece. The glue moistened the paper overlay enough that when put under stress it pulled the paper right off. Scrapped that idea and bought some regular ply. I have used MDO (medium density overlay) for outdoor projects with great success. But that is it's intended use. The Low Density Overlay will definitely NOT work for this!
Thanks for replying - (I was a little disappointed by the lack of activity on this forum)
Hi Rich, good to hear you got it sorted. I'm on my 3rd board now so have worked out a few things so let me know if you have any other questions that I may be able to help with. Does seem to be a bit quiet on here as you say.
