ABSTRACT:
The steps of surfacing a screen organization to include an initial mechanical cleaning of the screen organization by tools such as a sandblasting type member to direct abrasive particulates against the screen to effect a roughened surface on the screen. Subsequently, a coating of glue is applied to a bottom surface of the screen, whereupon the screen is positioned within a recessed cavity of a container. Parallelepiped block members are positioned within the openings defined by the screen organization, whereupon subsequently a fluid polymeric, such as polyurethane, is directed within the container, whereupon subsequent curing of the polyurethane permits removal of the newly surfaced screen organization.
