Latex-based formulations for coating and sculpting applications may provide blending a wet mixture with a dry mixture or blending a wet composition with a dry powder. The formulation may then be applied to a surface. In some embodiments, after the formulation is applied to a surface, the formulation may be set to the surface by covering the formulation applied to the surface with a material and/or the formulation may be self-setting on the surface. The formulation may fill gaps in the surface, thereby reducing cracks and shrinkage of the surface. The formulation may be applied to surfaces in a plurality of applications that may include, but are not limited to, sculpting, molding, and cosmetic repairs.

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.

A method for forming a super-insulating material for a vacuum insulated structure for an appliance includes disposing hollow glass spheres within a rotating drum, wherein a plurality of interstitial spaces are defined between the hollow glass spheres. An anchor material is disposed within the rotating drum. The hollow glass spheres and the anchor material are rotated within the rotating drum, wherein the anchor material is mixed with the hollow glass spheres to partially occupy the interstitial spaces. A silica-based material is disposed within the rotating drum. The silica-based material is mixed with the anchor material and the hollow glass spheres to define a super-insulating material, wherein the silica-based material attaches to the anchor material and is entrapped within the interstitial spaces. The silica-based material and the anchor material occupy substantially all of an interstitial volume defined by the interstitial spaces.
