Pure Linseed Oil - Raw, Special Aged from Red River Valley

Premium pure linseed oil obtained from flax grown in the Red River Valley of the U.S. and Canada. Our linseed oil is purified and refined through natural oxidation and blowing, resulting in an oil that dries as clear or clearer than tung oil, with none of the characteristic yellowing or discoloration typical of hardware store varieties.

Ideal For

Furniture finishing, wood floors, interior woodwork, cutting boards and butcher blocks, wooden utensils, antique restoration, wood turnings, musical instruments, mixing custom finish blends, and any interior wood project requiring deep penetrating protection with a natural appearance.

What Makes Our Linseed Oil Different

Unlike typical hardware store linseed oil that yellows and darkens over time, our specially aged and purified linseed oil dries crystal clear. The natural oxidation and blowing process removes impurities and creates a superior finishing oil that won't discolor your wood. This is the same quality linseed oil used by professional furniture makers and restoration specialists who demand the best.

Deep Penetration for Lasting Protection

Linseed oil has the unique ability to penetrate deeper into wood fibers than any other finishing oil. This deep penetration provides protection from within, nourishing and preserving the wood while enhancing its natural beauty. The oil polymerizes (hardens) within the wood structure, creating a durable finish that lasts for years.

Application Instructions

Preparation:

• Wood must be clean, dry, and bare (no previous finish)
• Sand to 150-220 grit for optimal results
• Remove all sanding dust with tack cloth or vacuum
• Work in well-ventilated area at 65-75°F

Application Steps:

1. Apply Liberally: Using a brush or cloth, apply a generous coat of Pure Linseed Oil
2. Allow Penetration: Let oil soak into wood for 20-30 minutes
3. Wipe Off Excess: Using clean, lint-free cloths, wipe off ALL excess oil until surface feels dry
4. Drying Time: Allow 24-48 hours between coats (linseed oil dries slower than tung oil)
5. Apply Multiple Coats: Build up 3-5 coats for optimal protection and depth
6. Light Sanding (Optional): Lightly sand with 320-400 grit between coats for ultra-smooth finish
7. Final Cure: Allow 7-14 days for complete cure before heavy use

Mixing with Solvent

For easier application and faster drying, mix Pure Linseed Oil 50/50 with Pure Citrus Solvent or turpentine. This traditional formula allows deeper penetration on first coats and more manageable application. The solvent evaporates, leaving pure linseed oil cured in the wood.

Drying & Curing

Touch Dry: 24-48 hours between coats
Light Use: 5-7 days after final coat
Full Cure: 7-14 days for complete hardness
Food Safe: 30 days for food-contact surfaces

Linseed oil dries through oxidation (exposure to air), so good ventilation speeds curing. Warmer temperatures also accelerate drying.

Pro Tips

• Thin coats are better than thick coats - let the wood absorb naturally
• Always wipe off excess oil to prevent sticky surfaces
• Linseed oil dries slower than tung oil - be patient between coats
• The finish will continue to harden over the first 30 days
• Buff with soft cloth after final cure for enhanced luster
• Reapply annually or as needed to maintain protection

Safety Information

Immediately after use, place rags in water or lay flat outdoors away from buildings to dry completely, then dispose of properly.

Application Safety:

• Use in well-ventilated area
• Wear gloves to protect skin
• Keep away from heat and open flames
• Keep out of reach of children and pets
• Avoid eye contact
