Avoid working in direct sunlight or wind. Circa 1850 Tung Oil is only to be applied onto bare, stained, or previously oiled wood surfaces - never over any other type of finish. Use Circa 1850 Furniture Cleaner to remove dirt and polish. Wipe on a liberal amount of Tung Oil using a lint-free cloth. Let the oil penetrate for at least 10 minutes and then wipe off the excess with a clean cloth. On open grain or oily woods, such as oak, ash, walnut, mahogany, etc., wipe again after 20 minutes. Let dry for 24 hours. To smooth out the surface between coats, buff lightly with Circa 1850 Finishing Pads or steel wool (0000). Apply a second coat in the same manner as the first. To obtain a finish that is a bit shinier, a third and fourth coat may be applied, always waiting 24 hours between coats.
