Abstract
A process for inhibiting the staining of film-forming finishes applied to a tannin-containing wood substrate comprises applying to the wood substrate, prior to or concurrently with the surface film, an aqueous formulation containing a stain-inhibiting amount of magnesium hydroxide having a high surface area, thereby forming a leach-resistant magnesium hydroxide-tannin complex.
