Learn about Linseed Oil Finish

Linseed Oil Finish

Linseed oil is produced from the flax plant and is a popular wood finish. Linseed oil saturates deep into your furniture or floor’s porous wood, hardening into a protective layer. With a satin finish that offers moisture resistance and protection against scratching, linseed oil has become a popular wood finish that draws attention to the natural color and grain of the wood.

When looking for linseed oil, it is essential to know the differences between raw, boiled, and polymerized varieties. Raw Linseed Oil is non-toxic and creates a fantastic finished coat. Raw Linseed Oil’s issue is that it can take a long time to dry and sometimes as long as 2-10 weeks. Boiled Linseed Oil is not cooked but instead mixed with special drying agents to speed along the curing stage. Because of these additional solvents, boiled linseed runs the risk of emitting Volatile Organic Compounds (VOCs) and is deemed the least food safe of the linseed oil finishes. Finally, Polymerized Linseed Oil is a heated oil that benefits from increased viscosity and decreased drying time. Similar to Raw Linseed Oil, Polymerized Linseed Oil should contain zero VOCs.

Linseed Oil is a byproduct of seeds from the flax plant, a crop utilized by humanity since the dawn of civilization. When produced sustainably, this product is natural, chemical-free, and eco-friendly. With no solvents needed, this product is free of Volatile Organic Compounds (VOCs). Note that not all linseed oils are considered sustainable. Boiled Linseed Oil often contains drying solvents that release VOCs and contain known cancer-causing chemicals.

Linseed oil is obtained from the dry, fully-ripened flax plant seeds. It's a drying oil, meaning it can polymerize into a solid surface. It's a transparent to yellowish oil and is one of the most valuable natural oils.
