- Apply the first coat of tung oil: Use a soft brush or cloth to apply a thin, even layer of tung oil. Work in small sections to avoid the oil drying too quickly.
- Let it soak in: Allow the tung oil to penetrate the paint for about 15–30 minutes. During this time, the oil will absorb into the surface.
- Wipe off excess oil: After the oil has soaked in, wipe away any remaining oil with a clean cloth. This prevents a sticky or uneven finish.
- Repeat for additional coats: For a more durable finish, apply 2–3 coats of tung oil, allowing each coat to dry completely before applying the next.
- Buff the surface: Once the final coat is dry, lightly sand the surface with fine-grit sandpaper and buff it with a soft cloth for a smooth, glossy finish.

Can You Use Tung Oil Over Milk Paint?
Yes, you can use tung oil over milk paint, but it’s important to understand how they interact. Tung oil is a penetrating oil finish, meaning it soaks into the surface rather than forming a film. This makes it ideal for sealing milk paint, which is naturally porous.
However, there are a few things to keep in mind. First, tung oil should only be applied after the milk paint is fully dry. If you apply it too soon, the oil may not penetrate properly, leading to an uneven finish.
Also, tung oil works best on raw or lightly sanded surfaces. If the milk paint has a rough texture, it may need to be sanded down before applying the oil. This ensures a smooth, even finish.
Another consideration is the drying time. Tung oil can take up to 24–48 hours to dry completely, depending on the conditions. So, if you’re working on a project that needs to be handled quickly, you might want to consider other finishes.
In summary, yes, you can use tung oil over milk paint, but proper preparation and application are key to achieving the best results.

So, if you’re asking “What oil is used to seal milk paint?”, the answer is likely tung oil, especially if you want a strong, long-lasting finish.
What Is the Disadvantage of Tung Oil Finish?
While tung oil has many benefits, it also has some drawbacks that you should be aware of. One of the main disadvantages is its slow drying time. Tung oil can take up to 24–48 hours to dry, and it continues to harden for weeks. This means you can’t use the finished piece immediately after applying the oil.
Another downside is that oil is not very resistant to heavy wear or frequent use. While it provides good protection, it can become scratched or worn over time, especially on high-traffic surfaces like tabletops or chairs.
Additionally, tung oil is not as glossy as varnishes or polyurethane. If you want a shiny, high-gloss finish, tung oil may not be the best choice. It gives a soft, natural sheen that many people love, but it’s not suitable for all projects.
Finally, tung oil can be more expensive than other finishes, especially when buying high-quality, food-safe varieties. However, it’s still a cost-effective option for those who value natural materials and eco-friendly products.
So, while tung oil is a great finish for milk paint, it’s important to weigh the pros and cons before deciding to use it.
How Long Does Milk Paint Tung Oil Take to Dry?
The drying time for milk paint sealed with tung oil depends on several factors, including the temperature, humidity, and the number of coats applied. Generally, tung oil takes about 24–48 hours to dry to the touch, but it continues to harden for up to 2–3 weeks.
Here’s a breakdown of the drying process:
- First coat: Dries to the touch in 12–24 hours.
- Second coat: May take another 24–48 hours to dry.
- Final cure: Takes 2–3 weeks to fully harden and reach maximum durability.
It’s important to let each coat dry completely before applying the next one. Rushing the process can lead to a sticky or uneven finish.
If you’re working in a humid environment, the drying time may be longer. In dry or warm conditions, the oil may dry faster.
So, if you’re asking “How long does paint tung oil take to dry?”, the answer is that it typically takes 24–48 hours to dry to the touch, but it needs 2–3 weeks to fully cure.
