Teak is a popular type of wood. It falls under the category of hardwood, making it important that the wood receives optimal protection. At Osmo, we have teak oil specifically for indoor or outdoor surfaces. The teak oil consists of 100% natural oils and waxes, designed to provide optimal protection for your untreated teak wood surface. After using the teak oil, your wood will be protected against moisture and dirt for years.

Available for indoor and outdoor use
We have a solution for teak both indoors and outdoors. Indoors, TopOil protects your teak furniture. Outdoors, teak oil (Terras-Olie 007) provides durable weather protection for terraces and decking. For garden furniture, we recommend Natuurlijke Olie-Beits, or Terras-Olie.
Teak oil for outdoor use
Outdoor garden furniture is quickly affected by weather conditions such as mold, graying, and wood rot. Teak oil is the solution for protecting teak garden furniture, patios, decking, and fences. We recommend Osmo Terras-Olie 007 for this purpose. This colorless oil saturates the wood and protects it against moisture and dirt. For teak garden furniture, we recommend Natuurlijke Olie-Beits, or Terras-Olie. Natuurlijke Olie-Beits contains pigment and therefore protects longer against UV radiation and graying, extending the lifespan of the teak. Preferably apply the oil to bare wood with a brush.

Teak oil for indoor use
To treat teak furniture indoors, we recommend using Osmo TopOil. This finish protects your teak table or furniture against moisture and dirt. Thanks to Osmo TopOil, the surface remains well protected for years and is easy to maintain and clean. TopOil is specially developed for easy application with a polishing cloth. This makes it perfect for hardwoods such as teak. The colorless TopOil creates a wet look, which deepens the natural color of the wood.

Indoor usage instructions
The appearance and adhesion of our products may vary depending on the type of wood, surface, and application method. Therefore, we recommend testing the products beforehand using a sample.
- Shake the product well for 2 minutes. After opening the can, the oil and wax will have separated.
- Apply the first coat of TopOil to the new or sanded wood using a white pad or brush. Ensure that you apply the product along the grain.
- Buff the TopOil dry with the fleece pad within 20 minutes. Do this along the grain as well. Mistakes made during application can be corrected on the wet surface up to 30 minutes after application.
- The first coat takes approximately 8-10 hours to dry. Drying takes longer at lower temperatures or higher humidity. Good ventilation must be ensured at all times. Therefore, ensure that windows and doors remain open both during and after the treatment.
- Next, apply 3 more layers (4 in total) in the same way as the first layer. The color becomes more intense with each layer. Finish the color layer with a colorless layer. This means 1 color layer is 3 colorless layers, 2 color layers is 2 colorless layers, and 3 color layers is 1 colorless layer.
- TopOil takes approximately 8-10 hours to dry.If you are going to polish the surface, it is important to apply 4 layers. This is to adequately protect the surface against moisture.
