Any surface, particularly for reclaimed thirsty wood, high-wear furniture, wood floors, butcher block countertops, cutting boards, cabinetry, interior doors, wood trim, stairs and railings, tool handles and any project requiring deep penetrating protection with maximum durability.
Why Choose Concentrated Finishing Oil
Concentrated Finishing Oil contains a higher ratio of natural oils to solvent compared to our Original Finish. This makes it ideal for dense hardwoods that benefit from extra penetration, high-traffic areas that need maximum protection, and projects where you want to build up a more substantial finish. The concentrated formula means fewer coats are needed to achieve deep protection.
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:
- Apply Liberally: Using a brush, cloth, or applicator pad, apply a generous coat
- Work Into Wood: Rub the finish into the wood grain, ensuring complete saturation
- Allow Penetration: Let oil soak in for 15-20 minutes
- Wipe Off Excess: Using clean, lint-free cloths, wipe off ALL excess oil until surface feels dry
- Drying Time: Allow 24 hours between coats
- Apply 2-4 Coats: Build up protection with multiple thin coats
- Light Sanding (Optional): Lightly sand with 320-400 grit between coats for ultra-smooth finish
- Final Cure: Allow 7-10 days for complete cure before heavy use
Coverage
Approximately 400-500 square feet per gallon on first coat. Due to higher oil concentration, coverage may be slightly less than Original Finish. Subsequent coats will cover more area as wood becomes saturated.
Drying & Curing
Touch Dry: 24 hours between coats
Light Use: 3-4 days after final coat
Full Cure: 7-15 days for complete hardness
Food Safe: 30 days for food-contact surfaces
Drying times vary with temperature, humidity, and ventilation. Warmer temperatures and good air circulation speed curing.
Pro Tips for Best Results
- More thin coats are better than fewer thick coats
- Always wipe off excess oil - leaving oil on the surface causes sticky finish
- Work in sections on large projects to ensure proper wiping time
- Dense hardwoods benefit most from the concentrated formula
- The finish will continue to harden and deepen over the first 30 days
- Buff with soft cloth after final cure for enhanced luster
Safety Information
- 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

Composition
We disclose ALL ingredients that we use. Heritage Natural Finishes contain NO petroleum products, or metallic drying agents whatsoever! We use only the highest quality ingredients from the most sustainable sources possible. What you see here is what you get. If you have any questions, you can always call us!
Tung Oil
100% pure with no additives. This is the highest quality tung oil available; drying harder and forming a more durable finish than linseed oil alone. Both oils are dryer-free and slightly heat-treated (polymerized).
Special Aged Linseed Oil
Obtained from flax grown in the Red River Valley of the U.S. and Canada. It is purified and refined by natural oxidation and blowing, and dries as clear or clearer than tung oil, with none of the characteristic discoloration that is typical of hardware store varieties. No other finishing oil penetrates as deeply into wood.
Beeswax
Only filtered, chemical and bleach-free white beeswax wax is used. Beeswax adds visual depth of grain, smoothness, and elastic durability. Beeswax forms a skim coat that keeps the finish on the wood, slowing the evaporation of the solvent, which gives the oils more time for absorption.
Pure Citrus Solvent
This is the purest form of citrus turpenes (solvent), extracted from cold-pressed orange peel oil. This is the only solvent used in our finishes, and is also sold separately for thinning product or cleaning up. Pure Citrus Solvent is a safer alternative to mineral spirits, and other harsh solvents and can be used the same way.
Pine Rosin
Gum rosin extracted from pine sap and separated from the turpentine. This is the gum rosin found in heart pine, giving the wood its hardness and durability. We use only top grade, crystal-free, water-white rosin. No synthetic resins are used.
