Claim 10:
11. A method for installing a water control flooring system, the method comprising:
securing a plurality of wall isolation boards to a wall frame so that a floor edge of each wall isolation board is adjacent to a subfloor, the plurality of wall isolation boards secured to the wall frame in a way that forms a plurality of individual wall seams between adjacent said wall isolation boards;
securing a plurality of floor isolation boards to the subfloor so that a wall edge of each floor isolation board is adjacent to one or more wall isolation boards of the plurality of wall isolation boards to form a joint seam between the plurality of floor isolation boards and the plurality of wall isolation boards, the plurality of floor isolation boards secured to the subfloor in a way that forms a plurality of individual floor seams between adjacent said floor isolation boards, the plurality of floor isolation boards secured to the subfloor in a way that forms a subfloor seam between the subfloor and an outward edge of each floor isolation board, the outward edge opposite the wall edge;
installing a waterproof layer to cover the subfloor seam, the plurality of floor seams, and at least a portion of each wall seam, the waterproof layer comprising a waterproof resin applied to the plurality of floor isolation boards, to a portion of the subfloor, and to an entirety of an outward side of each wall isolation board; and
