Shining results: changing the sheen

A completely normal process: over time, satin surfaces become matter, and matt surfaces become glossier. If you would like to change the sheen, this can be done without any difficulties.

More sheen for matt wooden floors:

By polishing the surface with Osmo Liquid Wax Cleaner clear, you can give flooring more sheen.

Less sheen for glossy wooden floors: 

A too glossy surface can be corrected with a coat of Osmo Maintenance Oil 3079 Matt.
