This invention provides flexible adhesive compositions which can be used instead of joint reinforcement tape for securing a joint seam between abutting panels. Methods using the compositions are provided as well.

Enhanced adhesive composition for re-enforcing joints in gypsum panel construction

Provided are building panels comprising at least one magnet receptive element, methods for making such panels, and kits and methods for attaching objects to a panel without nails or screws.

Magnet receptive panels and methods

Provided are compositions and methods for expeditious wall installation by spray-applying a joint compound comprising a polymeric binder and hollow spheres.

Spray-applied joint compound, wall assembly, and methods and products related thereto

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.
