Abstract: Disclosed is a method of preparing a mat-faced cementitious article composite. A mat-faced article (e.g., board) is formed and the composite is formed upon application of a finish composition (e.g., hydrophobic). In one aspect, the mat-faced gypsum article comprises a mat having an inner surface adjacent to a cementitious core first surface and an opposite outer mat surface. An aqueous cementitious finish composition is applied to the outside mat surface to form the mat-faced cementitious article composite. Desirably, the finish composite can suitably be applied by a roller assembly comprising a finish roller. In some embodiments, the finish roller has an uneven surface, including for example, grooves or depressions (e.g., circumferential or longitudinal) defined therein.

Abstract translation: 公开了一种制备垫层水泥质制品复合材料的方法。 形成垫面制品（例如板），并且在施用整理剂组合物（例如疏水性）时形成复合材料。 在一个方面，垫面石膏制品包括具有与水泥核心第一表面相邻的内表面和相对的外垫表面的垫。 将水性胶结剂组合物施用于外垫表面以形成垫层水泥制品复合材料。 期望的是，整理复合材料可以适当地由包括精加工辊的辊组件施加。 在一些实施例中，精加工辊具有不平坦的表面，包括例如在其中限定的凹槽或凹陷（例如圆周或纵向）。
