I am buying a house which has a pine floor in the bathroom, treated with Osmo oil.
Having the boards themselves well-oiled will make them waterproof, but there will also be cracks and gaps which develop over time. I am concerned that splashes and damp will make their way down between the cracks and cause mould and other problems.
How should I seal the small gaps in a way which is maintainable and compatible with the oil coating?
