How do you use Dark Tung Oil?
Dark Tung Oil is a natural, penetrating finish that provides a rich, dark matte color while deeply protecting wood fibers. Because it is a thick, pure oil, the application process focuses on total saturation of the wood.
- Surface Preparation: Ensure your workspace is well-ventilated and the wood surface is clean and free of dust. Dark Tung Oil is best applied to raw wood or surfaces previously finished with Tung Oil.
- The Application Process:
- Initial Application: Apply the Dark Tung Oil generously using a brush, rag, foam roller, or sprayer. Work methodically to ensure the oil contacts all areas of the wood.
- The Soak Period: Allow the oil to absorb into the wood for up to 40 minutes. Deep absorption is essential for a durable, water-resistant finish.
- Building Saturation: Apply another coat of oil once the previous one has soaked in. Repeat this apply-absorb-repeat cycle until the wood no longer accepts the oil. Most projects require 3–5 coats to reach full saturation.
- Checking for Saturation: The wood is fully saturated when the oil puddles on the surface and remains there for about 40 minutes without soaking in.
- Removing Excess: Once saturation is reached, use a clean, lint-free cloth to thoroughly wipe off all pooled oil. Removing the excess is vital to prevent the finish from becoming tacky or curing unevenly.
- Overnight Rest: For the most durable finish, let the wood rest overnight. You may apply one or two additional coats the following day to ensure a consistent, deep color and maximum protection.
- Curing:
- The Timeline: Dark Tung Oil cures via oxidation, reaching a partial cure in 15 days and a full cure in 30 days.
- Care During Cure: During the first 15 days, you can use the surface lightly, but avoid standing liquids and heavy objects.
- Airflow: Ensure the project has constant airflow. Placing objects on the wood too early can "suffocate" the finish and significantly slow the curing process.
