  • Patent number: 5763070
    Abstract: A shaped or flat article, having a skid resistant surface is adapted for use on floors, stairs, ladder rungs, and ramps particularly in moist and wet locations where a highly durable surface is required. The article is prepared by cleaning a surface of a ferrometallic base followed by application of a polychloroprene primer layer to the surface from an organic solvent. This is then followed by adhering and covering the primed base, in the area where the skid resistant surface is required, with a thermosetting epoxy resin. Partially embedded in the resin are particles of a grit material. One or more additional layers of a suitable coating such as paint may be applied on top of the cured resin for visibility, luminescence, cleanability, and added protection.

  • Patent number: 5475951
    Abstract: A shaped or flat article is described, having a skid resistant surface useful on floors, stairs, ladder rungs, ramps and other locations where a highly durable surface is required. The article is prepared by etching and cleaning a surface of the metallic base followed by adhering and fully covering the base, in the area where the skid resistant surface is required, with a flexible mesh layer embedded in a thermosetting resin such as a flexible epoxy resin. Partially embedded in the resin over the mesh are particles of a grit material. One or more additional layers of a suitable coating such as paint may be applied on top of the cured resin for visibility, luminescence, cleanability, and added protection.
