Abstract
A composite facer material for use with cementitious wallboards, where the composite facer is embedded in a top and bottom face thereof.

The first layer is preferably a carded polyester nonwoven mat, which is bonded to a second layer comprising preferably a tri-directional laid scrim fabric reinforcement layer made of continuous glass fibers. The two layers are preferably bonded together using an acrylic adhesive, which offers superior adhesion between the layers as well as superior adhesion between the composite facing material and the cementitious core.
