It is an excellent option for treating outdoor furniture, decks, and fences. However, it takes a long time to dry, and it may take several days or even weeks to achieve the desired results.
Boiled linseed oil, on the other hand, has been treated with chemicals to speed up the drying process. The oil is heated, and metallic drying agents are added to it. The final product is thicker and darker than raw linseed oil. Boiled linseed oil dries faster than raw linseed oil, but it is not as effective in penetrating the wood fibers.
Application and Maintenance
Linseed oil is easy to apply. You can use a brush, a cloth, or a sprayer to apply it to the wood surface. However, you need to be careful when applying it, as it can be flammable. You should not apply linseed oil on a hot day or in direct sunlight.
Linseed oil requires regular maintenance. If you use raw linseed oil on your wood surface, you need to reapply it every six months to a year. Boiled linseed oil lasts longer and needs to be reapplied every two to three years. You also need to clean the wood surface thoroughly before applying linseed oil to ensure that the oil penetrates deep into the wood fibers.
Benefits for Wood Treatment
Linseed oil is an excellent option for wood treatment. It is an all-natural product that enhances the natural color of the wood. It also penetrates deep into the wood fibers and provides long-lasting protection against moisture and UV rays. Linseed oil is also an eco-friendly option, as it is made from natural ingredients.
Overall, linseed oil is a great option for wood treatment. It is easy to apply, provides long-lasting protection, and is eco-friendly. Whether you choose raw or boiled linseed oil, you can be confident that you are using a high-quality product that will enhance the natural beauty of your wood surface.
