A water repellent composition comprising slag and organosiliconate salt characterized in that the concentration of the slag is from 1-5 wt % based on the weight of the plaster and the concentration of organosiliconate salt is from 0.5-2 wt % based on the weight of the plaster.5

A mortar composition, in particular a leveling mortar composition, including: a) 10-50 wt. % of a hydraulic binder, b) 10-25 wt. % of lightweight aggregates, c) 30-50 wt. % of further aggregates which have a particle density that is higher than the particle density of the lightweight aggregates, d) 0.5-5 wt. % of a polymer.

The present invention relates to an improved drywall finish and joint compound comprised of a mixture of fractured aluminum oxide, glass bead, calcium sulfate, calcium carbonate, magnesium aluminum phyllosilicate, aluminum silicate hydroxide, polyvinyl acetate, polyvinyl alcohol, metamorphic mineral, sodium bicarbonate, silicon and aluminides, talc, kaolin, and metal oxide. The improved drywall finish and joint compound is capable of adhering to drywall, wood, concrete, brick, stone, steel and other surfaces, and can be applied using a conventional trowel or similar device, cures quickly, and eliminates the need for taping and bedding. The compound saves extensive time and labor when installing, repairing or working with drywall.

A plaster composition includes a joint compound/drywall mud and from about 0.5 wt % to about 10 wt % silica (e.g., amorphous silica, hydrophilic fumed silica, and/or hydrophobic 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.

A high solids, sprayable, fast drying, ready-mixed setting-type joint compound comprising a blend of a joint compound mixture comprising: joint compound mixture ingredients comprising: calcium sulfate hemihydrate (e.g. US Gypsum's HYDROCAL C-Base), a chelating agent, and water; and an activator mixture, wherein the activator mixture comprises: activator mixture ingredients comprising: inert filler, set accelerator, and water, wherein a weight ratio of joint compound mixture:activator mixture is 1:1 to 100:1, wherein the activator mixture viscosity is the same as the joint compound mixture viscosity plus or minus 50 percent, and wherein the joint compound has about 55 to about 80 wt. % solids and a viscosity of 2,500-28,000 cps.

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 two-component polyurethane composition including a polyol component and a polyisocyanate component, wherein the polyol component comprises at least one polyester polyol A1 based on dimer fatty acids and/or dimer fatty alcohols having an OH number of 65-350 mg KOH/g, at least one polybutadiene polyol A2 and at least one alkoxylated alkylenediamine A3. The polyurethane composition has high strength and only a minor dependence of the mechanical properties, especially strength, on temperature, especially in the range from −40° C. to +100° C.

A wall compound for use in all applications and particularly well-suited for joining adjacent wallboards. The compound includes a latex resin, a thickener, fibers, and a filler material. In some embodiments, the repair compound is configured to exhibit at least one of yield stress and pseudoplastic-type behavior. In some embodiments, the compound includes hydrophobic and hydrophilic fibers of different morphologies. In some embodiments, the wall compound includes one or more associative thickeners.

Disclosed herein are paver adhesives including dry concrete mixes. The paver adhesive can include cement, silica sand, alumina silicate, and latex or acrylic polymer. The paver adhesive can be configured to be applied to a substrate in a dry state. The paver adhesive can be configured to become hydrated subsequent to pavers being installed over the paver adhesive, and the paver adhesive can be configured to cure and adhere paver tiles to the substrate following the hydrating.

A composition configured to form a heat generating layer on a building element is disclosed. The composition includes a base material and an electrically conductive filler, wherein the composition is configured to form a heat generating layer after it has been applied to a surface of the building element. The composition may be a construction adhesive or jointing composition, a gel coat composition or a bedding or self-levelling composition.
