Linseed oil is a very useful product in the treatment of wood as an alternative to varnish, since it creates a fine protective film, which allows the wood to breathe naturally. Its fine waxy layer makes it an excellent waterproofing agent for coatings, exterior facades, buildings, outdoor furniture, fences, doors and windows. On the other hand, linseed oil is a common ingredient in oil paints and latex paints, as it increases their adhesion to various surfaces.
Linseed oil has many beneficial properties for the maintenance of wood. Also, being a product of natural origin, it has a minimal carbon footprint; prevents the appearance of cracks, cuts and bends in the wood, providing greater durability; and acts as a protective barrier against the harmful effects of humidity, heat and rain. The type of flaxseed oil applied will more or less enhance these attributes.
Usually, we can find two types of linseed oils:
These two types of linseed oil are sometimes marketed with a blotter to facilitate application and minimize waiting time after application.
It’s a simple process that can be done with a brush for flat surfaces or a cloth for curves. But before getting down to work, keep in mind that it should never be applied to previously varnished wood, as it will not adhere well. Also, before oiling, make sure to thoroughly clean the wood surface, removing any dirt. And finally, it’s a good idea to read the manufacturer’s instructions to determine if the oil needs to be thinned with mineral spirits or other solvents, as well as the proper application rate.
Begin by applying the first coat of oil along the grain of the wood consistently and evenly for best results. If at least three coats of linseed oil are applied, the wood has good nutrition. Depending on the type of oil, the drying time may vary. As we have seen, the drying time is usually between 12 and 24 hours.
