We have recently replaced our floorboards in our front room with new pine floorboards. We are a bit concerned about what to do next. We would like the floorboards to look aged and not "yellow" we have tested a sample floorboard and used caustic soda to age it before putting a clear satin natural oil wax on, but the board looks slightly yellow and we believe would get damaged and show up marks. Can anyone help me with some ideas to age new pine floorboards. thanks in advance Gemma
