This depends on the general footfall, the type of footfall, cleaning and the general maintenance of the wooden floor. On average, domestic sanded and varnished wooden floors should last 5-10 years and commercial areas 3-5 years, however in all environments, we highly recommend that a maintenance contract is in place with an appropriate daily or deep clean process and a periodic ‘buff’n’Coat’ revive regime, which should create a lifelong finish to the floor.
