Gypsum panels and methods of making the same are provided herein. The gypsum panels include a barrier coating on a second surface of a coated fiberglass mat, the second surface comprising a coated surface, with the barrier coating comprising an acrylic binder and a filler in an amount of from about 50 to about 75 percent solids by volume of the barrier coating, the barrier coating being deposited in an amount of from about 46 lb/msf to about 60 lb/msf, dry weight. Sheathing systems of at least two such gypsum panels are also provided.

An emulsion composition includes an acrylic polymer, a metal silicate, and water. Advantageously, the emulsion composition provides coatings with superior adhesion of coatings to a concrete, clay, or ceramic substrate. In particular, the emulsion composition provides improved adhesion of the silicate primer to the concrete, clay, or ceramic substrate and strong cohesion between the primer and top coat paint allow for a much better overall performance. A method for applying the emulsion composition is also provided.

Disclosed is a two-part composition for sealing natural stone or masonry, and methods of use. The two-part composition is comprised of (1) a first part comprising a polyvinylidene fluoride (PVDF) particulate; a low evaporation rate organic solvent; and water; and (2) a second part comprising a blend of a plurality of liquid resin formulations.

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.
