Dark Tung Oil Usage Directions
The directions below are directly reprinted from the Real Milk Paint® website.
USE: The application is the same as our Pure Tung Oil. Dark Raw Tung Oil will give your work an instant antique water-resistant coating. It can be worked into the cracks and corners much like a glaze, giving the appearance of an old surface and patina. Dark Raw Tung Oil can be thinned 50% with Citrus Solvent, mineral spirits, turpentine or naphtha, which will improve penetration and drying time. The surface should be dusted to remove all loose particles. Alternatively, you can lightly sand the first coat before applying a second. Any filling or staining (water or alcohol stains work best) must be done before the oil is applied. The first coat should be a liberal one, and you can rub it over the wood with your hand using a soft rag. Allow this application to sit for 40 minutes so the oil can soak in. If it completely soaks in then apply another coat until the surface is saturated. After 40 minutes, remove any excess with clean soft rags. Check after about half an hour for any seeping, and rub this off as well. Let dry completely 24 hours between applications. Do not allow standing or puddles of oil to remain over night, these must be wiped away with rags. For dense hardwoods a solution of two parts Citrus Solvent to one part oil may be beneficial. Dark Raw Tung Oil will take 7 to 10 days for a minimum cure and 15 to 30 days for a full cure.
Dark Raw Tung Oil can be applied pure or with Citrus Solvent added if a non-toxic finish is required. Thinners can accelerate the drying process and greatly improve the penetration by cutting the first coat of oil with Citrus Solvent, mineral spirits or turpentine by 50%. Remember by adding mineral spirits or turpentine, Pure Tung Oil becomes toxic with these substances mixed into it, although the finish produced is not toxic because the driers evaporate.
The number of coats of oil to be applied will be determined by the intended use of the piece. Two to four coats are enough for decorative work, paneling and moulding. Surfaces that receive moderate to heavy use or handling could need up to six coats for maximum protection, plus a light renewal coat a couple of times a year. Apply till the surface reaches the saturation point. This will be evident as the surface will not absorb more oil. Renewal and building coats are quickly applied with cheese cloth, a lint free cloth or old nylon stockings. This process will give you a surface that will stand up to vigorous use and spills: water will bead on the surface.
Dark Raw Tung Oil is recommended for kitchen tables, chopping blocks and boards, and similar uses. Its non-toxic nature makes it particularly appropriate for children's toys and furniture. It gives good protection to wood panelling and moulding.
Dark Raw Tung Oil's matte finish will do nicely on certain pieces of furniture, but if a glossy finish is preferred you will need to buff and wax the finish, or use polymerized tung oil or a formulated tung oil based product.
We have found tung oil to be a valuable helper in the workshop. It adheres very well to metal, and a light coat rubbed onto tool steel is an effective rust inhibitor. Wooden handles will also benefit from the occasional coat.
FDA: Dark Raw Tung Oil is approved for food contact by the FDA. View document.
TIPS: If you find Dark Raw Tung Oil to be too dark, just mix with Pure Tung Oil to get the color you desire. With each application of Dark Raw Tung Oil your project may get darker. If you have achieved the color you want with your first coat, but would like more protection, just apply Pure Tung Oil for remaining coats. Let dry completely between coats 24-48 hours or until you see a consistent even sheen.
Keep containers tightly closed away from extreme temperature changes and open flames. As with all oils, rags, steel wool or waste soaked with oil, may spontaneously catch fire if improperly discarded. Immediately after use, place the oil soaked material in a sealed water-filled metal container or hang outside separately to dry.
