Application Guide
Linseed Oil
- Best For: Beginners, traditional aesthetics
- Prep: Sand rifle stock oil surface clean
- Apply: Wipe on thinly; wait 15–30 mins; wipe excess
- Repeat: 3–5 coats, drying 1–3 days each
Tung Oil
- Best For: Durability, water resistance
- Prep: Same as above
- Apply: Thin layers, 30–60 mins soak, then wipe
- Repeat: 5–7 coats; allow days to cure fully
Safety & Storage Tips
- Both oils can cause spontaneous combustion in soaked rags. Dispose in sealed, water-soaked metal container.
- Use boiled linseed oil only in ventilated areas (due to added drying agents).
- Pure tung oil is food-safe and non-toxic once cured.

FAQ Highlights
How many coats of tung oil?
4–7 coats; more on porous woods.
Can I apply polyurethane over linseed oil?
Yes—wait until it’s fully cured first.
Which is darker, linseed or tung?
Linseed deepens to an amber hue; tung keeps a clearer finish.
Dry time comparison?
Boiled linseed dries in 1–3 days; tung oil in 1–2 days per coat, but full cure takes longer.
Is linseed oil better than tung oil?
Between the two, tung oil tends to edge out linseed oil when it comes to toughness, moisture resistance, and how well it holds up over time. Both are plant-based and non-toxic, making them safe and eco-friendly choices. They work by soaking deep into the wood grain, but their long-term performance reveals key differences worth noting.
- Linseed Oil: Amber tint, easier to apply, but softens over time and needs regular upkeep Choose linseed oil for tradition and simplicity; choose tung for rugged use and moisture resistance.
- Tung Oil: Clear finish, cures faster, forms a harder, longer-lasting coat
How long does linseed oil last on wood?
Boiled linseed oil offers a faster turnaround—it typically dries within 1 to 3 days and, with regular care, can protect a gunstock for several months. Raw linseed oil, on the other hand, demands more patience. It can take anywhere from 2 to 10 weeks to fully cure, depending on the surrounding temperature and humidity. And because it doesn’t harden as thoroughly, it often needs more frequent touch-ups to maintain its finish.
Does tung oil dry faster than linseed oil?
Boiled linseed oil wins in the short term—it dries to the touch in just 1 to 3 days. But if you’re thinking long haul, tung oil is the sturdier choice. Though pure tung oil requires more patience—typically 24 to 48 hours between coats and several weeks to fully cure—it hardens into a tougher, more water-resistant finish that holds up better over time with less upkeep.
How many coats of tung oil should you use?
For the best results—especially on porous woods—plan on applying 4 to 7 thin coats of tung oil. Between each layer, lightly buff the surface with ultra-fine (0000 grade) steel wool to keep the finish silky smooth. Just be sure each coat has fully cured before adding the next—rushing this step can compromise the final result.
What is Tru oil Gunstock finish?
Tru-Oil was made with gunstocks in mind—and it shows. This refined blend of linseed oil and other natural resins dries quickly, resists yellowing over time, and forms a hard, glossy finish that holds up well against wear and tear. It’s a go-to for modern gunstock projects, especially if you want a clean, sealed look without a lot of hassle.
How many coats of Tru-Oil are needed?
Typically 3–6 coats suffice if pores are pre-filled. In humid climates, apply and dry Tru-Oil in 70–75°F conditions. Some enthusiasts go up to 24 coats for ultra-smooth finishes, but most see no added benefit past 6.
What can you put over boiled linseed oil?
es, but only after the linseed oil has fully cured (typically 3+ days). Compatible topcoats include shellac, Varathane, and Formby’s Tung Oil for extra protection and sheen.
Which oil gives a darker finish?
Linseed oil imparts a warm amber hue that deepens over time. Tung oil provides a clearer, natural look that preserves wood’s original tone.
How long does boiled linseed oil take to dry?
Expect 1–3 days to dry under ideal conditions. Raw linseed oil can take several weeks. Speed up drying by applying in a warm, low-humidity environment with good airflow. Boiled or polymerized varieties are preferred for quicker results.
