Joint compounds and spackling compounds which comprise a sanding indicator, the compounds displaying a first color at the surface upon drying/hardening. Methods for finishing a substrate or patching a substrate, the methods comprise applying the joint compound which comprises the sanding indicator and/or the spackling compound which comprises the sanding indicator and sanding the dried/hardened compound until the first color is removed. Accessory products which comprise at least one sanding indicator and methods for making joint compounds and spackling compounds comprising the sanding indicator.

Indicator for the sanding of joint compounds and spackles

A snap-setting joint compound with reduced calcium sulfate hemihydrate and improved sandability, as well as methods for building wall assemblies and repairing walls with the joint compound.

Setting type joint compound compositions with reduced plaster

A ready-mixed setting type joint compound in which formation of gypsum seeds has been inhibited. A method for controlling a setting reaction by mixing a ready-mixed setting type joint compound with one or more metal ion control agents comprising aminopolycarboxylic acid and/or a salt thereof, and further mixing the setting type joint compound with one or more non-calcium phosphate compounds. The method may further comprise mixing the setting type joint compound with a set activator obtained by blending together a first set activator including a cadmium compound, lead compound and/or zinc compound and a second set activator including a ferrous compound, aluminum compound and/or manganese compound.

Joint compounds, activators and methods for setting a joint compound and preventing seed setting

A building construction product comprising an ionochromic dye, wherein the building construction product has a first color when the product comprises water, wherein the first color is dependent on the presence of metal ions in solution in the product; and wherein the product has a second color when the product has solidified. Methods of monitoring setting and drying reactions of building construction products, including setting-type and drying-type joint compounds and plasters.
