Tung oil or China wood oil is a drying oil obtained by pressing the seed from the nut of the tung tree ( Vernicia fordii ). Tung oil hardens upon exposure to air (through polymerization ), and the resulting coating is transparent and has a deep, almost wet look.
Can tung oil be used on kitchen utensils?
Tung oil comes from tung nuts and is thus 100 percent food safe. Also, you can apply it to kitchen utensils such as butcher blocks, bowls, baskets, countertops, and cutting boards. Please give the finish 30 days to dry. Otherwise, the product’s chemical ingredients can release from the surface, causing lots of trouble.
How do you use tung oil?
Strip the Existing Finish With Trisodium Phosphate (TSP). Removing varnish and lacquer finishes is advisable before applying tung oil. Mix one water gallon with two TSP tablespoons. Then, use a sponge or brush to spread the mixture on the surface. Let the surface dry before further handling.
Can tung oil be used on wood?
When applied in many fine coats over wood, tung oil slowly cures to a satin “wetted wood” look with slight golden tint. It resists liquid water better than any other pure oil finish, though it still provides little protection against water vapor exchange or scratches.
