In general, the present invention is directed to a building panel, such as a gypsum board, comprising a core having a first side and a second side opposing the first side and at least one facing material having a coating comprising at least one fungicide, at least one polymeric binder, and at least one pigment. The panel satisfies at least one of the following: the board exhibits a rating of 2 or less when tested in accordance to ASTM G21-15 or the board exhibits a rating of at least 8 when tested in accordance to ASTM D3273-16. The panel may also exhibit at least a Level 3 finish.

The invention discloses a corrosion resistant coating for marine engineering concrete and a preparation method thereof, the corrosion resistant coating being sprayed or brushed on the concrete surface after being uniformly mixed by component A and component B,wherein the component A is calculated by weight including: waterborne non-ionic epoxy resin, C10-C12 alkyl glycidyl ether, polyhedral oligomeric silsesquioxane, metal powder, magnesium aluminum hydrotalcite powder,dispersant,defoamer; and the component B is calculated by weight including: modified aromatic amine curing agent, C10-C12 alkyl glycidyl ether, self-healing micro capsules, leveling agent, antioxidant, adhesion promoter, and other additives. The corrosion resistant coating of the present invention has excellent adhesion and corrosion resistance, while being able to achieve self-healing of the corrosion-resistant coating and prevent the migration of chloride ions, thereby prolonging the service life of the concrete structure, so that it can be widely used for the protection of marine engineering concrete structures.

Gypsum panels and methods of making gypsum panels are provided. Methods of making gypsum panels include: depositing a first gypsum slurry onto a first surface of a first fiberglass mat; allowing the first gypsum slurry to set to form at least a portion of a gypsum core; and applying a substantially continuous barrier coating comprising a polymer binder to a second surface, opposite the first surface, of the first fiberglass mat, in an amount of from about 1 lb/MSF to about 40 lb/MSF, such that the substantially continuous barrier coating has an average thickness of from about 1 micron to about 100 microns, wherein the substantially continuous barrier coating eliminates at least 99 percent of pin holes present in the exposed second surface of the first fiberglass mat.

A method of restoring a material surface utilizes a first composition (referred to herein as Composition A) and a second composition (referred to herein as Composition B). Methodologies guide application of Composition A and optionally Composition B to enact various restoration advantages to existing or new material surfaces. Composition A may be first applied to a material surface to remove surface contaminants and lift stains. During the described methodology, a user must wait a predetermined amount of time for Composition A to permeate the material surface. Optionally, Composition B may be subsequently applied to bond voids and damages areas of the material surface, or to add a new surface altogether above the original surface. A user may wait a predetermined amount of time for Composition B to cure.
