  • All weather wood sealer and marker
    Patent number: 4292086
    Abstract: An all-weather wood sealing composition is described. This composition can apply an apparently water impervious seal to a surface portion of wood which is dry, wet, or frozen. The composition can be applied under conditions of heavy rain or snow and produces a seal which is not readily removed by immediate immersion in water. The composition may be applied to an end of cut wood to provide a seal which inhibits cracking. When a suitable pigment is contained in the composition, the composition may be applied through a stencil or similar device to provide a water resistant marking on wood.
