Polishing oil is a light brown to reddish substance, which is used as a final color. This material is used together with sealer and killer or alcohol and varnish or alone to cover surfaces as a gloss. This color usually dries after 30 minutes. Note that polished oil does not have much resistance to high humidity, water and heat. Most of them use polishing oil in combination with oil paint to make the surfaces shiny and polished. You can use polished oil in decorative items, interior decoration, interior doors and exterior parts of the building that are not exposed to moisture. To apply this color, you should use a gun or a brush. Polishing oil is often produced and supplied to the market in liquid form in plastic or metal cans, which creates a transparent layer on the work surface after use. Usually, drying materials are used inside the polishing oil, which makes the polishing oil dry faster.
