The wood should not remain sticky after a hardwood floor finishing oil has properly dried. If this happens, the most likely cause is that excess oil was not properly wiped off after application. It's important to completely wipe off any excess oil, as oil that remains on the surface of the wood will tend to become sticky once it has dried. Note that some Osmo products should not be wiped away after application, so it's important to read the manufacturer's instructions carefully before using these products.
