Linseed oil is most often used indoors, either on paneling, moldings, beams, furniture and even on floors. It is important to apply this finishing oil only on bare or previously oiled wood, since any other finish such as paint, varnish or wax will prevent the penetration of the oil.Painted, varnished or waxed wood will therefore need to be cleaned and/or stripped to bare wood before proceeding with linseed oil application. The surface must be sanded and dusted to ensure good penetration. Typically, three coats at 12 to 24 hour intervals are sufficient. When the last coat is completely dry, a light hand polishing can be done: This will enhance the satin finish and smooth the texture. The reason for this is that linseed oil is a drying oil that seeps inside the wood; Polished or varnished woods don’t allow linseed oil to seep in as much, and therefore are less effective.For best results - Any kind of raw wood (inc. teak, pine, burma, sheesham etc) , old woods, engineered wood surfaces, study table, guitars, etc.Will give okay results - varnished woods, brass objects (boiled linseed oil only), metal surfaces (boiled linseed oil only), wooden steps, paneling or other high usage wooden items.Do not use on - Epoxy resin tables
