Wood graining is the practice of imitating wood grain on a non-wood surface in order to increase that surface’s aesthetic appeal. Wood graining was common in the 19th century, as people were keen on imitating hard, expensive woods by applying a superficial layer of paint onto soft, inexpensive woods. Wood graining can be accomplished using either rudimentary tools or highly specialized graining tools. It is carried out in layers, with the first layer being a base, and then a second layer applied later, today usually by means of a sponge. Wood graining offers considerable cost saving vs. buying authentic wood doors or floor.
