Methods for installing underlayment systems include the steps of laying at least one piece of a pre-formed board over at least one first portion surface area of a sub-floor. The pre-formed board is preferably fire-resistant gypsum board, which may also be water- and/or moisture-resistant. A second portion surface area of the sub-floor, which is adjacent to each first portion surface area, is designated to receive a poured underlayment after a tub is installed over the laid at least one piece of pre-formed board. In some instances, a sound mat may be laid over each first portion surface area of the sub-floor, prior to laying the at least one piece of the pre-formed board, and, then, another sound mat may be laid over the second portion surface area of the sub-floor, after laying the at least one piece of pre-formed board and prior to pouring the poured underlayment.
A method for installing an underlayment for a floor of a dwelling, the method comprising:
A method for preparing a sub-floor for installation of a poured underlayment, the sub-floor including at least one first portion surface area and a second portion surface area, the sub-floor being part of a dwelling under construction, and the method comprising laying at least one piece of a pre-formed fire-resistant board having a top surface and an exposed edge over each first portion surface area of the sub-floor, the board having a substantially constant thickness throughout, each first portion surface area having a size approximately equal to a footprint of a tub and being located adjacent to the second portion surface area, each second portion surface area being left exposed to receive the poured underlayment thereover, wherein laying the at least one piece of pre-formed fire-resistant board over each first portion comprising laying the at least one piece of pre-formed fire-resistant board with the exposed edge facing the second portion surface area such that, when an underlayment is poured over the second portion surface area subsequent to installing the tub over the top surface of the at least one piece of the board, the underlayment abuts the exposed edge of the at least one piece of pre-formed fire-resistant board.
