It’s best to wait at least 2 to 3 days after refinishing floors with natural oil-based finishes before sleeping in the house. This allows time for the fumes to dissipate and the finish to begin curing properly. If you’re using a wax-based finish, allow 3 to 5 days, as wax takes longer to harden and can release lingering odors. Proper ventilation during this period is crucial to ensure air quality and prevent damage to the newly refinished floor.
