Abstract
An under counter mount sink sealing surface and method of making that provides a watertight interface between an under counter mount sink and a laminate counter as well as a simplified and more dimensionally accurate method of field installing the sink below the counter. The water impervious seal is tightly chemically bonded to the cutout lip of the laminate as well as to the entire area on the bottom face of the laminate countertop that contacts the entire profile of the top face of the under counter mount sink. The seal also aligns the sink into the correct location and contacts the entire surface of the as it is deck aligned or completely parallel to the sink top flange.
Claims8
A flanged seal for the mounting of an entirely under the countertop mounted sink comprising:
- a generally oval ring having a top edge, a bottom edge, an inner face and an outer face wherein said inner face is chemically bonded to an inner sidewall of a sink cutout in a countertop so as to form a continuous watertight seal wherein said seal has a planar flange that extends to cover an area that only matingly profiles that of the sink flange, said planar flange having a top face and a bottom face, and said planar flange extends normally from said bottom edge of said ring and said top face is chemically bonded to a planar bottom face of said countertop in the region adjacent said sink cutout;
- and wherein said flange bottom face is surface planed such that said bottom face is planar to and parallel to a top face of the mounting flange of a sink so as to create more surface contact between said sink and said seal.
A flanged seal adapted for the mounting of a completely under the countertop mounted sink comprising:
- a generally oval ring having a top edge, an inner face, an outer face, and a flanged bottom having an upper face and a lower face that extends to cover an area that only matingly profiles that of the sink flange, wherein said inner face is continuously leakproof sealed to an inner sidewall of a sink cutout in a countertop and said inner face is chemically bonded to both an edge of a laminate and to an edge of the planar substrate that the laminate is affixed thereon, and said flanged bottom upper face is chemically bonded to a bottom face of said planar substrate in the region adjacent said sink cutout.
