Outdoor wooden furniture and structures are constantly exposed to harsh sunlight, rain, UV rays, high humidity, and extreme temperature swings. Without proper finishing, wood quickly fades, cracks, absorbs moisture, and deteriorates.
L.Co Exterior Wood Oil is specially formulated to penetrate deep into the wood fibers, offering superior water resistance, UV protection, and enhanced natural grain beauty. Unlike thick surface coatings that crack and peel over time, L.Co protects from the inside out—preventing flaking and making future maintenance effort-free.
This step-by-step guide will walk you through the complete process of applying L.Co Exterior Wood Oil, from initial surface preparation to simple long-term care.
Preparing the Surface Before Application
- Surface Requirements:
- Ensure the wood surface is:
- Completely dry
- Dust-free
- Free of grease, oil, and impurities
- Cleared of old, peeling finishes
- Sanding Steps:
- #240 Grit: Smooths and levels the surface evenly.
- #400 Grit: Prepares the final surface for oil application.
After sanding, thoroughly blow away all dust paying special attention to joints, corners, and end grains.

Color Oil Application (If Needed)
Stir well before use and continue stirring during application.
Application Methods:
Rag / Cloth
Spray gun
Standard Application Process:
Apply the oil following the wood grain.
Rub evenly to ensure deep penetration.
Wipe off any excess oil.
If a deeper color is desired, spray an additional coat of tinted oil after the first layer has settled.
Recommended flash-off time is approximately 45 minutes before applying the final finish coat.
Apply L.CO Exterior Wood Oil
First Coat
- Apply exterior wood oil using a spray gun.
- Allow to dry for 2–4 hours.
Additional Coats
- Continue applying exterior wood oil using a spray gun to ensure even coverage.
- Allow 2–4 hours between coats.
Final Drying
- Allow the surface to dry completely for 12–24 hours before use.
Depending on the customer's needs, the basic finishing options are as follows:
- Option 1: 1 coat of colored oil + 2 coats of exterior wood oil.
- Option 2: 3 coats of exterior wood oil.
Surface Inspection & Final Finishing
- Visual inspection: Check the surface under angled lighting to identify wipe marks, overlapping areas, or uneven color.
- Smoothness check: Gently run your hand along the wood grain to ensure the surface is smooth, even, and free from roughness.
- Edges & corners: Check carefully to ensure even oil coverage, with no areas lacking oil or excess oil buildup.
- Water resistance test: Apply a few drops of water to the surface. A stable finish will cause the water to quickly form droplets.
- Color & excess oil treatment: Chromalign can be used to balance color when needed. If the surface still feels slightly sticky or unevenly glossy, wipe it again with L.Co Solvent before use.
→ The surface is ready for use only when it is even, smooth, clean, and fully stable.
Routine Exterior Wood Maintenance
Outdoor wooden items are constantly exposed to harsh weather conditions, making routine maintenance essential to preserve their protective layer.
Recommended Maintenance Schedule
Every 3–6 months: For areas directly exposed to sunlight, rain, or harsh environments.
Every 6–12 months: For covered areas or milder exposure conditions.
When to Reapply
Reapply a top coat of exterior wood oil when the surface shows signs of:
Decreased water repellency
Fading color
Surface dryness
Action: Thoroughly clean the surface and apply an additional coat of L.Co Exterior Wood Oil to restore maximum protection.
Timely maintenance extends the life of the oil finish and significantly reduces restoration costs compared to repairing severely degraded wood.
Important Notes for Outdoor Wood Finishing
The effectiveness of the oil finish depends on application conditions and the surrounding environment.
For Best Results:
Avoid direct, harsh sunlight during application.
Never apply oil to damp or wet wood.
Allow full drying time between coats.
Apply evenly using the right amount of oil.
Adjust as needed based on the specific wood species you are working with.
Following this process ensures maximum water resistance, UV protection, and long-lasting natural beauty for your outdoor wood.
Conclusion
Finishing outdoor wood with L.Co Exterior Wood Oil provides maximum protection against harsh weather conditions while preserving the wood's natural beauty. Thanks to its deep-penetrating formula, L.Co not only enhances water resistance and UV protection, but also makes future maintenance effortless.
