Abstract: Coating formulations for improving hide and holdout without sacrificing adhesion on cementitious substrates are provided. The coating formulations can achieve high hide and holdout with a low pigment volume concentration by utilizing particles with pre-selected oil absorption and particle size range. The coating formulations can be used as a functional for fiber cement substrates. When applied in combination with a top coat, the functional provides provide high hide and hold and enhanced adhesion while reducing pigment loading.

Abstract: A coating system which provides a stain finish on a fiber cement building article. The coating system comprising a sealing agent, a basecoat and a topcoat, wherein the coating system is disposed on at least one surface of the fiber cement building article whereby the sealing agent is disposed adjacent to the at least one surface of the fiber cement building article, the basecoat is disposed on the sealing agent remote from the surface of the fiber cement building article and the topcoat is disposed on the basecoat remote from the fiber cement building article.

Abstract: Described herein is a cementitious article and a method of making using a water-based manufacturing system that incorporates a closed-loop or partially closed loop water recycling system and an alkali removal process. The system, as such is environmentally friendly, saves resources, such as water and other raw materials, and reduces waste disposal. The system further provides for a cementitious article having a low alkali content. Articles prepared by one or more processes described herein have characteristics that include a low apparent density, high strength and high freeze-thaw performance as compared with an article of the same general formulation but made from a comparative manufacturing system that does not include an alkali removal process. Articles described herein are suitable for use as building products, such as siding, the underlayment panel, board, trim, fascia, roofing, decking, and fence.
