ABSTRACT:
An improved sealant cap which is comprised of a flexible material, preferably, but not necessarily made of lead or other material having the same properties of lead, having a first arm member which is inserted downward into the caulking material after the caulking material has been in place within the joint. The downward depending arm portion extends from a cap portion downward, so that as the arm member is pushed into the caulking material, the upper cap portion spans across the joint and rests on the adjoining stone members. There is further provided a plurality of ridges formed on the undersurface of the cap portion of the improved cap cover with the ridges increasing the area (by 50%) of the underside of the cap for the sealant to adhere to and the surface of the stone in such a manner as to prevent the cap from separating from the stone and insuring an elastic protection for the joints. In the preferred embodiment, the cap is constructed of material such as lead or other type of material having similar characteristics.
