New thread about my inability to find dark engineered flooring. I see plenty of unfinished engineered wood with 4mm wear layers for sale. Apparently these are meant to be stained somehow. However, I had an experienced floor stainer over here who told me not to try it because it would have to be glued down and so I'd have to get the 3/8" thick wood to allow for flexibility for gluing to an imperfect cement surface and then if there were any small humps anywhere they would just sand right through the wear layer while prepping the wood. He said he'd email me an estimate for staining anyway, but blew it off. Why is unfinished engineered wood sold if it can't be stained?
