had to remove the carpet from the complete upstairs of my lovely early 17c cottage to find lovely early 20c plywood in the middle section of the floor, so had a new floor cut with exactly the same size boards as the originals from reclaimed pine beams, now about to start to replace. but obviously my 'new' floor is clean and white and what original floor is left is very dark and original-what to do? i cant remove the remaining original as it has built in weardrobes on it.so do i try to strip the old bits of floor or try to darken the new floor? any ideas would be appreciated.
