L-bead: a leak prevention system for stucco surfaces

Abstract

The L-Bead system is a system for use as a plaster or stucco stop where the plaster or stucco meets a separate surface such as window or door frames or jamb. Typical plaster stop in the stucco masonry industry consists of a perforated strip running parallel to the jamb with a plastic edge acting to contain the applied plaster or stucco surface. Traditional plaster stop is routinely installed approximately ¼-inch away from jamb in order to account for differences in the raised height of the jamb or other surface. The resulting gap or space requires the installation of a backer rod between the plaster stop and the edge of the jamb. This can add considerably to construction time and costs. The L-Bead system provides a stop system which eliminated the need for the installation of a backer rod and thereby reduces the potential for leaks. The L-Bead system adds an additional plastic strip to the back and along the length of the stop. The L-Bead is installed flush against the jamb for a tighter fit, eliminating the need for a backer rod, and requiring only a small amount of caulking over the area for a finished job. This new system will save time and money and will significantly reduce the potential for leaks in these areas.

What is claimed is:  
     
         1 . A new stop system for mounting along the edge of where plaster or stucco material meets a frame or jamb of a window or door. The L-Bead consists of a perforated plastic strip with both a higher lip running along the length of the stop to contain the plaster or stucco material and an additional plastic strip attached to the back of the higher lip which abuts directly to the window or doorjamb, fills in the gap, and eliminates the need for installation of a backer rod thereby cutting down considerably on the potential for leaks.
