ABSTRACT:
A disposable mold form for use in constructing a concrete coping along the upper edge of a swimming pool, and a method of molding such coping. The disposable mold form comprises a plurality of elongated form sections each having a surface portion configurated in the finished shape to be imposed thereby upon the coping, and each having also an attachment portion adhesively attachable to the vertical walls of such pool adjacent the upper edges thereof. Each form section is lightweight, sufficiently stiff to confine a moldable mass of concrete spread thereagainst, and bendable along the length thereof to enable it to conform to either inside or outside arcuate corners along such vertical walls of the pool. In the method of molding a concrete coping, the side walls of the pool are first covered with tile or other water-impervious finish, one face of a double-faced pressure-sensitive tape strip is secured to the attachment portion of each form section which is then adhesively secured by means of the other face of such tape strip to the finished surface of the pool walls with the configurated surface portions of the form sections projecting thereabove. A seal element is positioned along the upper edges of the pool walls in overlying relation with the water-impervious finish thereof, and a moldable mass of concrete is then spread against the form sections. Upon curing of the concrete mass, each form section is stripped from its adhesive attachment to the water-impervious surface of the pool walls to uncover the coping.
