Abstract: Described herein are methods of forming a VOC and odor-reducing building panel. The methods include providing a substrate; applying a wet-state coating to a major surface of the substrate, the wet-state coating comprising carrier comprising water; and drying the wet-state coating, thereby evaporating at least 95 wt. % of the carrier to form a dry-state coating.
