Drying Oils

A drying oil wood finish offers a straightforward way to protect wood while preserving its natural appearance and feel. Unlike thicker film finishes that build on the surface, drying oils penetrate the wood fibers, enriching color and figure while leaving a finish that is easy to maintain and renew. Among the most widely used drying oils are tung oil and boiled linseed oil. Tung oil is valued for the clear, water-resistant finish it produces. Pure tung oil is an excellent choice for toys and food-contact items, polymerized tung oil cures more quickly and builds protection faster, while tung oil sealer provides an ideal foundation for subsequent coats. Boiled linseed oil remains a traditional favorite but cures to a softer film than tung oil and provides a warm amber tone. Traditionally used on kitchenware, walnut oil builds slowly, but the fresh oil doesn’t impart an aftertaste to food. Some formulations combine drying oils with soft waxes such as beeswax or candelilla. These oil/wax blends add a slightly higher sheen and modestly improve durability. Others include resins to impart a semi-gloss appearance and even greater protection. Specialized oils for exterior projects provide protection against the elements. Most drying oil finishes can be applied with a brush or cloth and then wiped to remove excess finish. Their forgiving application process makes them accessible to beginners, while the ease of repair and renewal appeals to experienced woodworkers. Whether you are finishing a table top, restoring an antique or protecting a newly completed project, these drying oil finishes enhance the wood rather than conceal it, allowing its texture, color and grain to remain the center of attention.
