Many years ago, my husand and I had replaced wood flooring in our house because it was stained dark brown. So we had some perfectly good white oak flooring, stained brown. After many years of storage, we took it to our farm. Here are the photos of the installation. That blue you see is underlayment that goes down first. The line of wood flooring that you see has been aligned with the stairs. It goes down first, then we work outwards on both sides to complete the room. Getting the flooring square in an old very unsquare cottage is a trick. Because we were using repurposed boards, some were curved a bit, some didn't have tongue & grooves at their ends where they had been cut, some had splintered when we took the old nails out. We just had enough wood to floor our loft, so we spent quite a bit of time trying to get the best use out of the wood....we were afraid we would run out. It was like a jigsaw puzzle. Here is the finished product:. (Keep in mind we haven't reconstructed those side cabinets yet) Interestingly, in the cottage the brown stain is not so dark!
