Abstract
A method and apparatus for applying a faux wood grain finish to plastic architectural plastic boards. The method employs a climate-controlled area for denibbing of boards to prepare a surface and a sprayer to achieve a desired depth of color. A wiper spreads the sprayed on material to form a faux grain finish which may include faux wood knots. The boards are directed through a combination infrared and convection oven having independent curing zones providing specific drying profiles. Once cured, the boards are cooled with forced air cool down fans and transferred into a climate-controlled area for applying a topcoat. The topcoat board is passed through an oven set to a defined temperature for curing and cooled down with forced air cool down fans before packaging and shipping.
