Remove all furniture and other items from the room and vacuum the floor to remove all dust and grime.
Mop the floor with a commercial wood cleaner to dissolve any grease on the floor. Rinse with plain water and allow the floor to dry thoroughly before proceeding.
Sand the floor with 120-grit sandpaper.
Vacuum the floor immediately before applying lacquer to ensure the floor is completely free of dust.
Pour a pancake-sized puddle of lacquer in the middle of the floor. Evenly distribute a thin layer of lacquer over the floor, using a lamb’s wool applicator. Wait one hour before ventilating the room to prevent air from disturbing the lacquer and causing bubbles and waves.
Buff the dry floor to a shine, using a buffing machine.
