Abstract:
Protection of wooden articles, such as railroad crossties, against decay or rot is improved through incorporation of borate compounds, such as sodium borate, and a protective coating such as creosote or a resin. Such protection is achieved by placement of a dry borate compound into a hole formed in the wooden article. The hole is then covered, and the borate compound then permitted to migrate and become distributed throughout the wooden article to provide the desired protection. Coating of the thus treated wooden article is conducted either shortly following placement of the borate compound in the hole or at a later convenient time.
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.
