What you need for this tutorial;
Do you want to protect your wooden furniture, floors, or garden wood and give it a beautiful look? Wood oil is the ideal solution. Whether it's a tabletop in the living room or decking in the garden, with the right oil, you protect wood against moisture, dirt, and discoloration. In this tutorial, you will discover how to apply wood oil, which products you need, and how to maintain your wood optimally.
Apply wood oil indoors
Interior wood requires a different approach than exterior wood. Furniture and floors need a softer, more refined treatment, but here too, protection is essential.
Step-by-step plan indoors
With this step-by-step plan for indoors, you ensure a strong and beautiful finish for your furniture or wooden floor.
Prepare wood
Check if the surface is even and free of old finishes. Is the wood rough or uneven? Then sand in three steps: start with grit 40, then move to grit 80, and finish with grit 120 for a smooth result. Afterwards, remove the sanding dust with a dry, lint-free cloth.

Choose the right oil
- For furniture, use Osmo Top-Oil.
- For wooden floors, use Osmo Hardwax-Oil.

Apply the first coat of wood oil
Apply a thin layer of wood oil with a roller or polishing cloth. Always work in the direction of the wood grain.

Let it dry
Allow the surface to dry for at least 8 to 12 hours with adequate ventilation.

Apply a second coat
For proper protection, apply a second thin layer. Allow this to dry thoroughly as well for a durable, natural finish.

Supplies
For a beautiful and durable finish on furniture and floors, you need the following:
Tips
Osmo interior wood oil is available in various colors, so you can always create the right look. These are the most popular finishes:
- Wet-look effect: emphasizes the color of the wood. After treatment, the color becomes darker; the wood takes on a tint as if it has been wetted.
- Untreated effect: choose a wood oil with white pigment as the first coat, and use a transparent finish as the top coat.
- Color: choose a uniformly colored effect where the wood grain remains visible.

Indoor maintenance advice
- Furniture: Clean regularly with Osmo Spray-Cleaner.
- Floors: Use Osmo Wisch-Fix when mopping for long-lasting protection.
- Avoid standing water or sharp objects that could damage the surface.
- Apply a new coat of wood oil when the wood becomes dull or shows signs of wear.
Apply wood oil outdoors
Exterior wood is exposed to sun, rain, dirt, and temperature fluctuations. Therefore, it requires an oil that offers protection against UV radiation and moisture. The right treatment prevents discoloration and extends the lifespan of your exterior wood.
Step-by-step plan outdoors
Exterior wood needs good protection against sun, rain, and dirt. Follow this step-by-step plan for the best results.
Clean the wood
Start by cleaning the wood surface. Use an Osmo patio brush and Osmo Patio Cleaner to remove dirt and green deposits. Is the wood greyed? Then apply Osmo Power-Gel, let it sit for 20 minutes, and scrub the wood clean. Rinse thoroughly with water and let the wood dry completely.

Choose the right oil
- Vertical wooden elements (such as fences or cladding): use Osmo UV protection oil.
- Horizontal wooden elements (such as terraces or decking): choose Osmo Terrace Oil.

Apply the first coat of wood oil
Use a block brush to apply a thin layer of oil, following the wood grain. Work carefully and evenly.

Let it dry
Let the wood dry for at least 12 to 24 hours in good weather conditions. Ensure adequate ventilation.

Apply a second coat
For optimal protection and a longer lifespan of the wood, apply a second thin layer of oil. Allow this layer to dry thoroughly as well.

Benefits of Osmo wood oil for outdoor use
Osmo wood oil protects your wood against external influences and preserves its natural appearance. Whether you are treating a terrace, fence, or facade, you benefit from these advantages:
- Protection against UV radiation, moisture, dirt, and algae
- Available in transparent and pigmented variants
- Preserves the wood structure and natural appearance
- Easy to refresh; no sanding or primer required
Outdoor necessities
To properly treat exterior wood and protect it for a long time, you need:
Tips
- Work on a dry day with temperatures between 10 and 25 °C.
- Preferably work out of direct sunlight to prevent rapid drying.
Colors and appearance
Osmo exterior wood oil is available in various shades. Many people choose a color that matches the wood type, such as teak or bankirai, to enhance the natural appearance.
Please note: colorless oil offers less protection against UV radiation and can lead to graying more quickly. A lightly pigmented oil provides better protection and leaves the wood grain beautifully visible.
Popular options include:
- Teak
- Bankirai
- Gray
- Colorless (limited UV protection)
Outdoor maintenance advice
- Clean twice a year with Osmo Patio Cleaner, especially for green deposits.
- Check annually whether a new coat of wood oil is needed.
- Has the wood turned grey? Then use Osmo Power-Gel to restore the color.
