ABSTRACT:
The present invention provides a method of coating a surface with a slip resistant coating. The method of the invention comprises either sequentially or simultaneously melting two different metal wires and directing droplets of the melted wires towards a surface to be coating. The resulting coating formed by this process tends to be rough and confers anti-slip properties to the surface. In one variation of the invention, the two different metal wires will be melted and atomized in a single spray gun. Alternatively, these wires may be melted in separate but adjacent spray guns. In either variation, the resulting metal sprays formed from the different wires will at least partially overlap.
