Just done the second coat of Osmo on an oak floor, but I can still see a couple of bare patches where it looks like there is no osmo applied. The patches are parts of the board right next to knots where there is changing grain direction and there was tear out on the board. I was very careful to cover the entire area, so it’s not spots where I’ve just missed applying oil.
Could be one of the following diagnoses:
1. Area is equivalent to end grain so it soaked up more oil. Apply more oil.
2. Grain has been raised above surface. Use a pad and hand apply more oil while knocking down grain.
3. Area is near knots that I filled with wax and traces of wax are repelling the oil.
4. Area could have been sanded by me and despite vacuuming dust, pores are clogged preventing oil absorption.
I think the answer is #2 raised grain.
It’s not just soaking up more oil, because I’ve tested and end grain isn’t really that different than other surfaces, but applying more oil is going to happen anyway, so this is covered by #2.
It’s unlikely to be wax traces because I would imagine the dark wax I used would be visible if so, the area is some distance from the filled area, and the wax doesn’t repel the oil anyway.
I don’t think it’s sanding dust. Any sanding I did was light, 100 grit, vacuumed thoroughly, and presence of dust might be indicated by milky look to finish which is not present.
So I think just hand applying more oil to the area using a pad that will knock off the raised grain is the answer.
Does that seem right? As you can tell I haven’t done much finishing. I guess just feeling it with my hand will tell me the answer.
(The osmo was applied with a roller for both coats so while I gave it a good scrub near knots, it wasn’t going to be knocking down raised grain).
