  • Patent number: 7762474
    Abstract: Coating adhesion on wooden members, such as wooden railroad crossties, is improved through use of three surface-treating techniques prior to application of the coating. The first technique involves forming grooves on the surface of the wooden article, the second technique involves exposing the wooden article to heat to reduce the moisture content of the surface of the wooden article, and the third technique involves creating incisions on the surface of the wooden article to further promote adhesion. The techniques may be advantageously used together to further enhance coating adhesion.
