The operative word here is ‘maintenance’. Always have a door mat to trap any grip or dust coming in from outside. Make sure to sweep or vacuum the rooms as often as possible, so that the dirt doesn’t cover the floor when it comes into contact with other objects. Identity areas that endure high traffic and watch out for wear and tear. When any are detected, apply fresh lacquer or wax on the area. If you wear shoes in the house or have children or pets, these will increase the chances of the floor needing more sanding. Therefore, you should reduce these factors where possible and increase every maintenance routine you will be practicing.
