Abstract
A waterproof juncture comprised of a water-impermeable membrane applied over at least the upper peripheral edge of a wallboard or shower pan sidewall and a portion of an adjacent wall-forming member which is coplanar with the wall studs, which in turn will form a waterproof covering over the seam between the upper peripheral edge of the wallboard or shower pan sidewall (or equivalent shower bench, shelf or ledge) and the adjacent wall-forming member.
Claims15
A waterproof flashing adapted to be installed in connection with a shower pan sidewall and a section of wallboard, the sidewall ending in an upper peripheral edge, the wallboard ending in a lower peripheral edge, room-facing surfaces of the wallboard and the sidewall being substantially coplanar and adapted to receive wall covering thereon, two or more vertically disposed shower wall studs each defining a front facing surface that is coplanar with the front facing surface of the other shower wall studs, the waterproof flashing comprised of:
- a generally horizontally disposed backing member connected to the two or more wall studs, the backing member defining a backing member front surface which is substantially coplanar with the front facing surfaces of the shower wall studs, the upper peripheral edge of the sidewall and the lower peripheral edge of the wallboard being disposed in opposed relation with respect to, and spaced from, each other, the upper peripheral edge of the sidewall and the backing member front surface forming a longitudinal intersection;
- and
- a continuous water-impermeable membrane applied over at least a portion of the room-facing surface of the sidewall, the upper peripheral edge of the shower pan sidewall and at least a portion of the backing member front surface.
A waterproof flashing adapted to be installed between an upper peripheral edge of a first member and a lower peripheral edge of a second member, room-facing surfaces of the first member and the second member being substantially coplanar and adapted to receive wall covering thereon, two or more vertically disposed shower wall studs each defining a front facing surface that is coplanar with the front facing surface of the other shower wall studs, the waterproof flashing comprised of:
- a generally horizontally disposed backing member connected to the two or more wall studs, the backing member defining a backing member front surface which is substantially coplanar with the front facing surfaces of the shower wall studs, the upper peripheral edge of the first member and the lower peripheral edge of the second member being disposed in opposed relation with respect to, and spaced from, each other, the upper peripheral edge of the first member and the backing member front surface forming a longitudinal intersection, and
- a continuous water-impermeable membrane applied over at least a portion of the room-facing surface of the first member, the upper peripheral edge of the first member and at least a portion of the backing member front surface.
A method of forming a waterproof flashing arrangement comprising the steps of:
- forming an enclosure, said enclosure being defined by a series of vertical shower wall studs, each defining a front facing surface;
- arranging a series of horizontally disposed backing members, each defining a front facing surface, around an upper peripheral edge of a shower pan, perpendicular to the vertical wall studs, wherein the font-facing surface of said horizontally disposed backing members are substantially coplanar with the front-facing surface of the vertical wall studs;
- mounting a continuous water-impermeable membrane to the horizontally disposed backing members around an upper peripheral edge of a shower pan, wherein the continuous water-impermeable membrane is positioned such that at least a portion of the continuous water-impermeable membrane overhangs the upper peripheral edge of the shower pan;
- and
- attaching a series of wallboard sections above the upper peripheral edge the shower pan, wherein a lower peripheral edge of the wallboard sections are spaced from each other in vertical alignment, wherein a room-facing surface of the shower pan and a room-facing surface of the wallboard are substantially coplanar.
