How do I treat my spruce wood?
Spruce wood can be used for all kinds of projects. For instance, spruce is used to construct canopies and carry out renovations. Spruce wood has a beautiful appearance, but untreated spruce is also vulnerable. Fungi, algae, moisture, and UV radiation can damage the wood. As a result, the appearance of the wood will deteriorate over time. Fortunately, you can treat spruce wood to better protect it against various weather conditions. With Osmo spruce oil, the wood is protected against moisture, algae, and fungi. If you choose an oil with pigment, you also prevent the wood from turning gray.

When you want to protect spruce wood, you can choose Osmo spruce oil. This oil is made from plant-based ingredients. Therefore, our products are not harmful to humans or animals. The oil we offer adheres well and protects the spruce wood optimally. Do you want to protect spruce wood against moisture? Then our spruce oil is perfectly suitable!

Why protect spruce wood from moisture?
It is important to properly protect spruce wood against various weather conditions. If the wood becomes constantly damp, its lifespan will decrease drastically, as it will rot more quickly. Moreover, damp wood is ideal for fungi and algae. If you forget to treat spruce wood, there is a high chance that after a few months the wood will look grey and be covered in algae. That would, of course, be a terrible shame! If you decide to protect the wood with our spruce oil, it will remain beautiful for years to come.
How should you treat spruce wood?
Do you want to stain spruce wood outdoors? Then choose one of our exterior oils. It does not matter which of our natural oils you choose. For instance, you could even apply Bankirai oil to spruce wood. The difference lies in the color. If you want the spruce wood to retain its natural look, we recommend using our wood oil specifically for spruce. Want more information before you get started? Then first read our comprehensive knowledge center article on exterior wood oil.
Before applying the spruce wood oil, you must stir the product well. The wax and oil need to be mixed together. After stirring for about two minutes, you can test the oil. Is the result to your liking? Then you can apply a first coat with a brush or roller. Mistakes, such as a brush hair sticking to the wood, can still be corrected up to about fifteen minutes after application.
After application, the first coat will need to dry. It takes approximately 10 to 12 hours for the oil to dry. The exact time it takes for the oil to dry depends on the temperature and humidity. When treating spruce wood, it is important to ensure good ventilation. Make sure no precipitation is expected when you are going to treat the spruce wood.
Once the first layer of spruce oil has dried, you can apply a second layer. Again, it is important to ensure good ventilation. It takes approximately 12 hours for the second layer to dry as well. Once that is done, the spruce wood is optimally protected.
Staining impregnated spruce wood
Do you want to treat spruce wood that has already been impregnated? That is often perfectly possible. However, if you have previously treated the wood with another stain, we do recommend sanding it first. Additionally, we offer various tools that can help you remove paint or oil. Have you previously treated the wood with our oil and is the wood due for maintenance? Then you do not need to remove the existing layer first.
