A method for coating a building panel, including applying a first coating fluid including an organic binder on a surface of the building panel to obtain at least one coating layer, and applying barrier components and photocatalytic particles, preferably TiO.sub.2, on the at least one coating layer. Also, a building panel formed by the method.

A building board including a cementitious layer between two fiber mats. At least one fiber mat forms with a polymer film a fiber mat/polymer film laminate. The cementitious layer of the building board contains a reactive water-insoluble polymer which improves binding of the fiber mat/polymer film laminate to the cementitious layer. The building board has a low water absorption and a high level surface finish.

The invention comprises a product. The product comprises a foam insulating panel, the panel having a first primary surface and an opposite second primary surface, wherein the foam insulating panel defines at least one recessed channel in the first primary surface, the at least one recessed channel being sized and shaped to provide a mold for a structural reinforcing member. The product also comprises a concrete panel formed on the first primary surface and filling the at least one recessed channel so as to provide a structural reinforcing member for the concrete panel. The product further comprises an elongate anchor member in the foam insulating panel and extending from the first primary surface of the foam insulating panel into the concrete panel. A method of making a composite reinforced insulated concrete structure is also disclosed.

Panels usable for construction of a surface, to provide the surface with a desired appearance, durability, water, air, and fire resistance, dimensions, and weight include a layer of substrate material having first and second sides. Finish elements are positioned on the first side, while a backing material is positioned on the second side, such that the substrate bonds the finish elements to the backing material. Particulate material can also be included, such as within spaces between finish elements. Manufacture of such panels can include use of a vacuum system that acquires finish elements in a selected orientation, acquires particulate material into spaces unoccupied by finish elements, then deposits the arranged finish elements and particulate material into a mold for subsequent manufacturing steps. Use of lightweight, durable materials, such as magnesium oxide, can enable panels having a reduced thickness and weight to be manufactured, without sacrificing durability or longevity.

Gypsum panels, sheathing systems, and methods of making and using the same are provided. A gypsum panel includes a gypsum core associated with a first fiberglass mat having a continuous barrier coating, the coating penetrating a portion of the first fiberglass mat opposite the gypsum core, wherein gypsum penetrates a remaining fibrous portion of the first fiberglass mat such that voids in the first fiberglass mat are substantially eliminated. A building sheathing system includes at least two gypsum panels and a seaming component to provide a seam at an interface between the gypsum panels.
