Abstract
Engineered wood product edges are protected by applying a two part edge sealing composition to at least one edge surface. The two part edge sealing composition can improve holdout, hide, and water resistance. An edge sealing system and substrates coated with the sealing system are provided.
Claims27
A method for coating an engineered wood substrate comprising the steps of:
- providing an engineered wood substrate;
- and
- applying a two part coating system having a first part comprising a polymeric coagulating agent and a second part comprising an aqueous coating composition to at least one surface of the substrate.
