We laid pine floors that lead out to a small pine deck in our new tiny house build. Now we need to finish them. We have decided to go with clear deck oil on both the interior and exterior. I would like to slightly darken the pine a little to avoid the orangey ageing that happens to this wood. I am looking at doing a homemade coffee stain but am not sure how it will react with the oil finish.

Has anybody done this? Any feedback before we start would be much appreciated.
