METHOD OF PREPARING MAT-FACED ARTICLE |
摘要 |
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. |
