Hello to all - I've been scrounging wood for the last two years and have a good years supply c/s/s. Just waiting for the seasoning to occur. Mean wile I just got a Pick-up truck load of "old" gym floor. This stuff is the tongue and groove hardwood that was a high school gym floor. All the nails have been removed and the finished side of the wood is peeling off a clear coat of varnish, ureathane (sp) or whatever they used to coat the gym floor with. I was just looking for any expert opinions on weather burning this "finished" hardwood would have any ill effects on the Cat converter in my Woodstock fireview.. Anybody out there ever burned this type of wood before?
