摘要:
A method of finishing an interior wall includes the steps of preparing a substrate of building panels including gypsum, cement or combinations thereof, the substrate having a surface, followed by applying a coating to the substrate, the coating having 1-30% by weight of a latex emulsion binder, 30-80% by weight calcium sulfate hemihydrate, up to about 8% by weight of a set inhibiting agent and 20-60% by weight water.
摘要:
Disclosed is a composition (e.g., a texture composition) comprising, consisting of, or consisting essentially of calcium carbonate and superabsorbent polymer that can absorb at least about 50 times its mass and having a particle size of about 250 microns or less, wherein the composition is substantially free of a setting-type cementitious material. In some embodiments, cellulosic thickener content is reduced or eliminated from the texture composition. Also disclosed is a method of finishing a substrate comprising applying to the surface a wet composition comprising, consisting of, or consisting essentially of calcium carbonate and superabsorbent polymer that can absorb at least about 50 times its mass and having a particle size of about 250 microns or less, wherein the composition is substantially free of a setting-type cementitious material, and drying the composition on the substrate.

A plaster composition for making molds for reproduction by casting is disclosed. Calcium sulfate hemihydrate, potassium sulfate and potassium sodium tartrate are mixed together. The potassium sulfate and potassium sodium tartrate are in a ratio of from about 1:1 to about 10:1. Potassium sodium tartrate is present in an amount of from about 1 to about 10 pounds per ton of dry calcium sulfate hemihydrate, and the total of the potassium sulfate and potassium sodium tartrate is from about 2 to about 35 pounds per ton of calcium sulfate hemihydrate. Methods of making and using molds of this composition are also disclosed.
摘要:
A composition and method for treating a set gypsum-containing material are disclosed. The composition is formed from at least water at least one trimetaphosphate salt, at least one monobasic phosphate salt, and at least one acyclic polyphosphate salt having at least three phosphate units. The method comprises applying to a set gypsum material at least two of the following inorganic phosphates: at least one monobasic phosphate salt, at least one trimetaphosphate salt, and at least one acyclic polyphosphate salt having at least three phosphate units. The method can be for inhibiting re-calcination of a set gypsum containing material, and/or for enhancing the strength, surface hardness, paintability, abrasion resistance, and/or water erosion resistance of a set gypsum-containing material. Also disclosed is a method of making a set gypsum-containing material.
