What will the maintenance be for a lacquered floor?
The main advice is to have good clean door mats, to sweep and vacuum regularly and to keep an eye on any areas that get lots of traffic i.e. by the sink or in an entrance hall. When these show signs of wearing through ask someone to apply another coat of lacquer. I would expect a floor to survive for quite few years before a new coat is needed. In theory, if you keep the abrasive dust and dirt particles away it will last for ages, maybe longer than you!
