Introduction
Tung oil is one of the most revered natural finishes in woodworking, and when it comes to achieving the best results, using the best polymerized tung oil for wood finishing is essential. Tung oil is one of the most revered natural finishes in woodworking, known for its deep penetration, durability, and stunning enhancement of wood grain. However, not all tung oil is created equal. In this comprehensive guide, we’ll uncover everything you need to know about tung oil—its benefits, curing process, and why Bumblechutes' polymerized tung oil stands out as the best choice for your woodworking projects.
What is Tung Oil?
Tung oil is a natural drying oil extracted from the seeds of the tung tree (Vernicia fordii). Used for centuries in woodworking, it penetrates deeply into wood fibers, forming a durable, water-resistant finish that enhances the wood’s natural beauty.
Unlike synthetic finishes that form a film on the surface, tung oil bonds with the wood, creating a flexible, breathable layer that won’t crack or peel over time.
Raw vs. Polymerized Tung Oil
Raw tung oil is pure and natural but slow to cure — often taking weeks between coats.
Polymerized tung oil (like Bumblechutes’ S’Tung Oil) is heat-treated to begin the polymerization process early. This means it dries faster, cures harder, and penetrates deeper, with no harsh solvents or additives.
How Long Does Tung Oil Take to Cure?
One of the biggest challenges with tung oil is its curing time.
Raw tung oil can take anywhere from 4 to 6 weeks to fully cure due to its slow oxidation process. This lengthy drying time can be impractical for woodworkers who need faster turnaround times.
The Solution: Polymerized Tung Oil
Polymerized tung oil undergoes a specialized heating process in an oxygen-free environment, significantly speeding up drying times and improving durability. Bumblechutes' polymerized tung oil is an exceptional choice because it produces no harmful fumes or VOCs, making it a safe and eco-friendly finish for both indoor and outdoor projects.
Cure time depends on conditions, but here’s a general guide:
Type | Dry to Touch | Recoat Time | Full Cure |
Raw Tung Oil | 2–3 days | 5–7 days | 20–30 days |
Polymerized Tung Oil | 4–8 hours | 24 hours | 7–10 days |
Why Polymerized Tung Oil is the Best Choice for Wood Finishing
Unlike synthetic finishes that sit on top of the wood, polymerized tung oil bonds within the fibers, creating a durable, water-resistant seal without plasticizing the surface.
Top Benefits:
✅ Faster Drying Time – Cures in 12-24 hours per coat instead of weeks.
✅ Superior Durability – Forms a harder, more resilient finish.
✅ Increased Water Resistance – Provides immediate protection against moisture.
✅ Deeper Penetration – Absorbs more effectively into the wood, creating a longer-lasting bond.
For these reasons, Bumblechutes exclusively uses polymerized tung oil in all tung oil-based products.
💡 Pro tip: Thin coats and patience yield the best results. Tung oil loves oxygen — let it breathe between layers!

How to Apply Tung Oil for the Best Results
Prepare the Wood
Sand the surface smoothly (150-220 grit), remove dust, and make sure wood is clean and dry.
Apply the First Coat
Use a lint-free cloth or brush to spread the oil evenly.
Let it Soak
Allow 20-30 minutes for the oil to penetrate, then wipe off excess.
Repeat as Needed
Apply 2-4 coats, allowing 12-24 hours of drying time between coats.
Let It Cure Fully
After the final coat, allow 7–10 days for full polymerization before heavy use.
The Importance of Applying Thin Coats
When applying tung oil, thin coats are essential for proper curing and optimal results. Thick coats take significantly longer to dry, often leaving a sticky surface that can delay the curing process. By applying multiple thin coats, the oil penetrates deeply into the wood fibers, allowing oxygen to interact with the finish more efficiently. This results in a stronger, more durable bond and ensures that the finish develops its full water-resistant and protective properties. Additionally, thin coats help prevent streaking, uneven absorption, and excess buildup on the surface, which can lead to an inconsistent finish. For best results, always wipe off any excess oil after 20-30 minutes and allow ample drying time between applications.
