I have extended a room and kept part of the old parquet floor, and in the extended area laid reclaimed parquet blocks. It is now all sanded flat, but is very pale in colour. The original floor was quite dark. I don't know what the wood is. I have Osmo Polyx Clear Satin hard wax oil at the ready, but presume that when this is applied there will be very little change in colour. Does anyone know whether the parquet can be stained or dyed before applying the hard wax oil?
