A premixed photoluminescent composition and related hardened form and method of forming joints for pavers or stones. The premixed photoluminescent composition comprises solid aggregates; a photoluminescent particulate component adapted to emit light when photoexcited; and a binder. When in contact with an activator, oxygen or water, the binder is adapted to harden into a water-resistant binder matrix that bonds the solid aggregates and embeds the photoluminescent particulate component. In use, the water-resistant binder matrix has a transparency allowing transmission of at least a portion of the light emitted by the photoluminescent particulate component.

A drying-type joint compound can comprise: (a) a primary filler at about 50 weight percent (wt %) to about 98 wt % on a dry basis, wherein the primary filler includes one member selected from the group of calcium carbonate, calcium sulfate dihydrate, and talc, and a mixture thereof; (b) a secondary filler at up to about 25 wt % on a dry basis; (c) a binder at about 1 wt % to about 15 wt % on a dry basis; (d) a polymer thickener at about 0.05 wt % to about 3 wt % on a dry basis; (e) a vesicle dedusting agent at about 0.01 wt % to about 10 wt % on a dry basis, wherein the vesicle dedusting agent comprises vesicles; and (f) an additive up to about 10 wt % o on a dry basis; and (g) water at a ratio of water to dry components of about 1:6 to about 3:1.

Provided herein is a joint compound having a composition to allow tools to easily clean up, comprising water, at least one inert filler, and a binder comprising a sulfonated starch, and a method of preparing the joint compound.

A plaster composition includes a joint compound/drywall mud and from about 0.5 wt % to about 10 wt % silica (e.g., hydrophilic fumed silica). The plaster composition may be a repair composition. The repair composition may be dispensed as an aerosol using a propellant. The repair composition may be useful for repairing popcorn textured ceilings.

Embodiments of a system and a method for continuously manufacturing a joint compound can be used to produce ready mix joint compound. The system includes means for continuously mixing wet and dry joint compound ingredients together and means for homogenizing multiple volumetric units of mixed joint compound to reduce variation in at least one joint compound material property (e.g., viscosity) across multiple successively produced volumetric units of mixed joint compound (relating to standard commercial packaging sizes for joint compound, such as five-gallon pails, for example) relative to the material property of the respective multiple volumetric units before passing through the means for homogenizing.

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.

A cementitious composition with accelerated curing at low temperatures particularly at temperatures <5 C., especially at temperatures <0 C. The cementitious composition consists of 2 components with a first component A including at least one ordinary Portland cement, at least one cement selected from calcium aluminate cement and/or calcium sulfoaluminate cement, a powder P, selected from the group consisting of carbonates or hydrogen carbonates of alkali and/or alkaline earth metals, optionally aggregates, optionally other additives and a second component B comprising at least one accelerator, an anti-freeze agent, water, and optionally other additives.
