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.

A superhydrophobic coating is provided and contains organosilane, an inorganic nanomaterial, and an emulsifying agent. A mass proportion of the components is controlled, so that the superhydrophobic coating can form a micro-nano mixed microstructure inside foam concrete. The organosilane first forms dense hydrophobic surface layers on the surface and in inner pores of the foam concrete, and the nanomaterial forms uniformly distributed nano-bulges on the hydrophobic surface layers formed by the silane. The superhydrophobic performance of the foam concrete can be effectively improved by combining the two microstructures. The foam concrete exhibits excellent superhydrophobic performance.
