This is the old barn floors we originally bought for the bedroom, finding a new home in the hall after a run or two though the planer. Still needs a BLO/Turp mix applied...and to be finished of course! We put down a layer of tar paper, then sleepers, then the floor.
We did a little test on the kitchen floor to try to remove the old adhesive from the floor using mineral spirits.
Needs some more work. We are going to try a steamer next. Mineral spirits are stinky and it's not all that warm out to have everything opened up.
