is it possible to stain douglas fir dark?
i recently hired a professional floor refinisher to sand and refinish the douglas fir floors in my 100+ year old house. i wanted them to be very dark so that they would match the downstairs as well as possible(oak with aniline dye)...he sanded, then wiped on an oil-based stain of some kind, which looked perfect. then he applied several coats of a high-gloss polyurethane, because he said hi-gloss would hold up better. he claims he sanded between coats, but almost immediately the polyurethane began peeling off in high traffic areas (within days). he did wait several days for the stain to dry first... he says that it isn't possible to stain doug fir very dark, and that the thick layer of stain is what made the poly peel. he also suggested that maybe it peeled because we later washed the floors with water, but it peeled right away, before any washing ever happened. i don't see any stain coming up at all, only the poly. i'm going to try and redo it with my dad, but he's never worked with fir, only harder woods, and i don't want the same thing to happen again. so my question is-is it possible to stain douglas fir very dark, and if so, how? what products/method? sorry for the long post! thanks!
