Fabric and reinforcements are provided by this invention which, in a first
embodiment, include a plurality of warp yarns having a first twist
(turns/inch) and a plurality of weft yarns having a second twist which is
greater than the first twist. A coating is applied over a substantial
portion of the warp and weft yarns after they are assembled or laid
together, so as to produce a weight distribution ratio of less than about
2.0:1, based upon the weight of the resinous coating of the weft yarns
over the weight of the resinous coating on the warp yarns. This can be
achieved, in substantial part, due to the difference in the twist ratios
of the warp and weft yarns, which difference permits a more uniform
coating to be applied. Further embodiments of this invention include a
cementitious board and methods of making a coated fabric and cementitious
board.
