I applied a heavy coat on an elementary gym floor (maple) once, many years ago. I don't know if the architect that spec'd it knew what he was doing, and have never been back to see the results over time. I just remember the fumes were really bad, but that is not prohibitive with a small surface area.... But it was definitely amberizing, so you should be aware of that. I saved the remnant from the job, and it did skim up heavy, pretty quickly. So save your extra in small, air tight jars, if you don't trust the Blo stuff. R Mann
