Introduction
In this article, we will explore the differences between raw and boiled linseed oil for wood treatment. Linseed oil, derived from flaxseed, is widely known for its health benefits when consumed as a supplement. However, in the realm of wood treatment and preservation, linseed oil takes on a different role. Brouns & Co, an expert in the field, provides valuable insights on the properties and applications of raw and boiled linseed oil. We will delve into the characteristics of these oils, their uses, and the importance of treating wood with the right type of oil.
Understanding Raw Linseed Oil
Raw linseed oil is obtained through the cold pressing and filtering of flaxseeds. It possesses a light yellow color, reminiscent of honey. One of the key features of raw linseed oil is its low surface tension, which enables it to penetrate timber more effectively than water. However, this property makes it unsuitable for grinding pigments into it, as it cannot pass through rollers satisfactorily. In the production of high-quality linseed paint, each grain of pigment must be fully coated in oil.
Exploring Boiled Linseed Oil
To overcome the limitations of raw linseed oil, Brouns & Co employs a process called boiling. By boiling the raw linseed oil, it undergoes a transformation, resulting in a darker color and increased viscosity. Boiled linseed oil becomes a superior carrier for pigments, providing better coverage and ensuring that the pigment adheres to the surface effectively. This is crucial for achieving a high-quality linseed paint. It is important to note that heating linseed oil on its own is not recommended, as it alters the viscosity and can cause damage to the timber.
The Significance of Boiled Linseed Oil in Primer Coats
When mixing your own primer coat or using Brouns & Co’s primer coats, boiled linseed oil is an essential ingredient. The low surface tension of boiled linseed oil allows the primer coat to penetrate deeply into the timber, providing optimal protection. By adding boiled linseed oil to the paint, it acts as a carrier, enabling the paint to reach even deeper into the wood. It is worth emphasizing that heated linseed oil should never be used as a standalone treatment for wood surfaces, as it can lead to expansion and contraction, ultimately compromising the integrity of the timber.
Limitations of Raw and Boiled Linseed Oil for Exterior Applications
While both raw and boiled linseed oil are effective for wood maintenance and paint production, they are not suitable for exterior applications on their own. Without additional protective properties, these oils do not offer sufficient protection against external elements. Brouns & Co has addressed this concern by developing a specialized product called Nourished Wood Oil. This formula includes a UV protector and antimodal growth properties, making it ideal for exterior use when a clear finish is desired. Nourished Wood Oil provides enhanced protection and preserves the natural beauty of the wood.
Conclusion
In conclusion, understanding the differences between raw and boiled linseed oil is crucial for effective wood treatment. Raw linseed oil excels in penetrating timber due to its low surface tension, while boiled linseed oil serves as an excellent carrier for pigments in linseed paint production. When it comes to exterior applications, Brouns & Co’s Nourished Wood Oil offers the necessary protection and preservation capabilities. By selecting the appropriate linseed oil for each task, wood enthusiasts can ensure optimal results and longevity in their projects.
