Things You'll Need
Fine steel wool
Linseed oil comes from the seeds of the flax plant. It can preserve and beautify wood and leaves a wonderful sheen on the wooden surface. Use only boiled linseed oil as the drying time will be much faster. A linseed oil finish can be renewed by applying once a month or sooner if you see the surface becoming dull. Linseed oil sinks into the pores of the wood and hardens, creating a tough and durable protection.
Start with a clean wooden surface. Wipe, brush or spray the linseed oil on the wood and let it set at least 1 hour. You may want to let the wood rest overnight to ensure the oil is completely absorbed.
Buff the wood with the fine steel wool. Sand the wood lightly to remove any roughness. Apply more coats, sanding between each one.
Rub linseed oil onto the wood with a cloth until the surface is saturated. Rub the wood firmly to bring out the shine.
Use linseed oil in a well-ventilated area.
Beware of the toxic fumes if you mix turpentine with linseed oil.
