Abstract: Aspects of the disclosure are directed to apparatuses and/or methods involving a wall patch. As may be implemented in accordance with one or more aspects characterized herein, a wall patch has a plurality of layers including a base layer having an upper surface and a lower surface, and stacked layers stacked over the upper surface of the base layer. Each stacked layer is stacked on one of the other layers and has an exposed lower surface region that extends laterally beyond the layer upon which it is stacked. Adhesive may operate to adhere the exposed lower surface regions and the lower surface of the base layer may be adhered to a wall surface. The stacked layers, base layer and adhesive to provide a gradient defined by the thicknesses of the layers and adhesive, and defined by the area of the exposed lower surface regions of the stacked layers.

Abstract: Aspects of the disclosure are directed to apparatuses and/or methods involving stacked layers of material. As may be implemented in accordance with one or more aspects characterized herein, an apparatus includes a base layer of material with upper and lower surfaces, and stacked layers of material on the base layer. The stacked layers include a first layer stacked on the upper surface of the base layer, and further layers stacked on and adhered to one of the other stacked layers. At least one of the stacked layers has a lower surface area that is larger than a lower surface area of one of the stacked layers on which it is stacked, with an adhesive on an exposed portion thereof.

Abstract: As may be implemented in accordance with one or more aspects characterized herein, a wall patch is adhered to a wall surface having a damaged region. The wall patch has a base layer and a plurality of layers of transparent material stacked on the base layer, with the base layer being visible through the transparent material and therein aligned around the damaged region. A surface coating is applied to an area of the wall surface around the wall patch and to the wall patch, after which a top removable layer of the wall patch is removed to expose a top surface of an underlying one of the layers. A further coating is applied to the exposed top surface of the underlying layer, and to the area of the wall surface around the wall patch.

Abstract: Described herein is a texture material dispensing system that includes a foldable handle and trigger. The texture material dispensing system may be used for dispensing a texture material onto a target surface, such as a ceiling.

Abstract: Aspects of the disclosure are directed to a spray gun apparatus having a casing with a nozzle. A rod extends within the casing and has an end portion with openings therein, for dispensing material. The rod operates with the casing to move relative to one another, for selectively dispensing the material. When the nozzle is positioned such that it is offset from the end portion of the rod, fluid material is allowed to flow out of the rod and is dispensed through the nozzle. When the end portion of the rod is positioned to seal the nozzle opening (e.g., via relative movement of the casing and rod), the fluid material is prevented from being dispensed through the nozzle. In certain implementations, an adapter interface is operable for coupling to an aerosol container having the material to be dispensed, and includes a conduit coupled to the rod for supplying the material.

Abstract: Removable, aqueous-based compositions, especially sealants useful for, inter alia, temporary craft applications and seasonal weatherization of buildings and methods of their use are disclosed. These sealants reduce the flammability risks and lingering odor problems associated using solvent-based systems, particularly during application. These compositions do not rely on additives that disrupt the adhesion of the compositions to the substrate and that leave undesirable residue on the substrate.

Abstract: A formulation technology for low pressure two component polyurethane foam-funning compositions containing gaseous hydrohaloolefin blowing agents is described with improved storage stability and extended shelf-life. The “B”-side component of the formulations contain a gaseous hydrohaloolefin blowing agent and a polyol pre-mix, the polyol pre-mix comprising liquid blowing agent, polyol, and a catalyst containing at least one catalytic metal compound.

Abstract: The present invention is directed to ready to use (wet) and setting (dry) repair products with antistatic additives having reduced persistent airborne dust particulates upon sanding thereof. Such wet and dry repair products include, in part, an antistatic additive(s) that can reduce or eliminate the static charge that forms in dust particulates when dried repair products, such as spackling compounds, cementitious materials, and joint compounds, are sanded, for example. In turn, this can help reduce the quantity of airborne dust particulates, the time in which they are suspended, and the distance they travel in a given room or job site. In one example, a repair product for use as a dry repair compound can include an anti-static additive, which can include a cationic charge, and optionally a metal complex. In another example, the repair product further includes water to define a wet or ready to use repair product.

Abstract: A ready to use patch repair product is disclosed that includes a color change indicator therein. After the product has dried the color changes to signal that, if desired, the worker can perform other operations such as painting, sanding, etc on the surface. In one aspect of the invention, a substantially ammonia and ammonium salt free latex polymer is used as the resin binder component. This provides enhanced color stability in the stored product.

Abstract: Stable foam caulk, sealant and insulation compositions are disclosed. These compositions comprise aqueous emulsions of film forming polymers in combination with microfibers. The preferred film forming polymers and the microfibers include functional groups capable of forming bonds, particularly hydrogen bonds, between these components. In another aspect of the invention, the compositions include a high temperature foam stabilizer, such as a high molecular weight fatty alcohols, having melting points greater than about 110° F.

Abstract: Stable foam caulk, sealant and insulation compositions are disclosed. The compositions comprise solid, waxy non-ionic lipophilic surfactants having low HLB values. These surfactants, upon foamed dispensing of the composition, provide stable support for bubbles formed from drying of a latex emulsion of a film forming polymer and a volatile liquid hydrocarbon propellant. In addition to use in caulking, sealant or insulation methods, the composition can be used to form artificial terrains and other hardenable structural surfaces as backgrounds or support means for hobbies, crafts, and the like.

Abstract: Stable foam caulk, sealant and insulation compositions are disclosed. The compositions comprise a waxy, solid foam stabilizer and a liquid lithophilic surfactant having low HLB value of about 3-14. The foam stabilizer provides stable support for bubbles formed from the drying of the latex emulsion of film forming polymer, and the volatile liquid hydrocarbon propellant. In addition to the use in caulking sealant or insulation methods, the compositions can be used to form artificial terrains or other hardenable structural surfaces as backgrounds or support means for hobbies, crafts and the like.

Abstract: A combination cap and material tooling device is provided including an elongated blade supported on a base wherein the base includes an engagement portion and an intermediate portion. The engagement portion is preferably provided with threads for engaging threads on a container for a spackling stick whereby the contents of the container may be sealed from air to thereby preserve the contents in a soft pliable putty-like consistency. The intermediate portion is located between the blade and the engagement portion and includes a finger depression for receiving an operator's finger whereby the base may be comfortably used to guide the blade in a spackling operation.
