    摘要： Mat-faced cementitious board including: (a) a cementitious core; (b) a fibrous mat having an inner first surface facing at least one face of the cementitious core, and an outer second surface, wherein the inner first surface and the outer second surface are opposed; (c) a hydrophobic, non-setting coating resulting from applying to the outer second surface of the fibrous mat a layer of hydrophobic finish composition including: (i) about 50 to about 80 weight % non-setting, inorganic filler having a mean particle diameter of about 12 microns to about 35 microns, (ii) about 20% to about 50 weight % an aqueous dispersion of a film-forming polymer, (iii) 0% to about 30 weight % additional water; (iv) an absence of fly ash, (v) an absence of pozzolanic material, (vi) an absence of hydraulic cement, (vii) an absence of calcium sulfate hemihydrate, and (viii) an absence of calcium sulfate anhydrite.

    摘要： Disclosed are cementitious articles with hydrophobic finish. In some embodiments, the article is a waterproof gypsum panel that is surface reinforced with inorganic mineral fibers that face a flexible and hydrophobic cementitious finish possessing beneficial waterproofing properties. The waterproof gypsum panels of the invention are useful in many applications, such as, for example, tilebacker board in wet or dry areas of buildings, exterior weather barrier panel for use as exterior sheathing, and roof cover board having superior water durability and extremely low surface absorption. The flexible and hydrophobic cementitious finish of the invention can include Class C fly ash, film-forming polymer, silane compound (e.g., alkyl alkoxysilane), and otheroptional additives.

    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.
