A coating including a relatively thin visible-absorptive layer atop a relatively thick non-absorptive, solar-scattering underlayer. The thin top layer enables efficient absorption of appropriate visible wavelengths to show specific colors, and minimizes absorption in the infrared radiation in sunlight due to its relatively small thickness. Meanwhile, the bottom layer maximizes the backscattering of infrared light without absorption to reduce solar heating.

A system for installing pre-painted moldings. The system includes pre-painted moldings each configured to be fastened to a wall by fasteners. The system also includes a caulk material, filler material, concealer material, and touchup paint each color matched to the paint color applied to the moldings. The caulk material is configured to fill a gap defined between each of the moldings and the wall to which the molding is fastened. The filler material is configured to fill a gap defined between any abutting portions of the moldings. The concealer material is configured to conceal any surface disturbances caused by the installation of the fasteners. The touchup paint is configured to adhere to the paint pre-painted on the moldings. The system may also include a marker configured to apply a coating color matched to the paint applied to the moldings, a scraping tool, and/or a buffing tool.

Disclosed is a method to produce composite materials, which contain customized mixes of nano- and/or micro-particles with tailored electromagnetic spectral properties, structural elements based thereon, in particular layers, but also bulk materials including inhomogeneous bulk materials. In some embodiments the IR-reflectivity is enhanced predominantly independently of reflectivity for visible wavelength. The enhanced IR-reflectivity is achieved by combining spectral properties from a plurality of nano- and/or micro-particles of distinct size distribution, shape distribution, chemical composition, crystal structure, and crystallinity distribution. This enables to approximate desired target spectra better than know solutions, which comprise only a single type of particles and/or an uncontrolled natural size distribution. Furthermore disclosed are methods of manufacturing such materials, including ceramics, clay, and concrete, as well as applications related to design and construction of buildings or other confined spaces.

The invention relates to a plastering machine for applying a surface coating layer to a building surface, such as to a in building wall (1), comprising: a coating material supply (20) connected to a mouthpiece (30) via a flexible hose (15), said mouthpiece (30) including a rear wall (31) connected to a first side flange (34′) and to a second side flange (34″) opposite said first side flange (34′), characterised in at least said first side flange (34′) comprising a first spacer device (40′) defining together with said rear wall (31) a part of a coating material chamber (8), a discharge area (37) for coating material contained in said chamber (8) extending between said opposite side flanges (34′, 34″), said first spacer device (40′) being releasably connected to said first flange (34′).

A process for the preparation of a concrete structure including casting a layer of concrete, application of a waterbased curable resin system on the wet cast concrete layer and subsequently mechanical incorporation of the waterbased curable resin system into the concrete layer. The mechanical incorporation of the waterbased curable resin system into the concrete layer, which can advantageously be combined with trowelling of the cast concrete surface, the adhesion of a subsequent applied coating onto the thus treated concrete layer is significantly improved particularly in relation to peel strength. Further, a coated structure prepared by this process, which is particularly a floor.

A method for forming a self-leveling floor includes: positioning an edging form on or adjacent to a subfloor so as to at least partially bound an area on which a self-leveling floor is to be formed, the edging form including: a body having a top face, a bottom face and a first side face that extends between the top face and the bottom face; and a plurality of spaced apart channels extending entirely through the body from the top face to the bottom face, each of the plurality of channels also passing through at least a portion of the first side face. A self-leveling flooring material is dispensed into the area in which the self-leveling floor is to be formed so that the self-leveling flooring material flows against the first side face of the body and into each of the plurality of channels.

The application discloses a high-whiteness MGO substrate, a preparation method thereof and a decorative board having the substrate. The high-whiteness MGO substrate includes a surface layer and a substrate, wherein the substrate is prepared from a forming agent, a lightweight filler, a modifier and water in parts by mass as follows: 40-49 parts of light burned magnesium oxide powder, 18-25 parts of magnesium sulfate heptahydrate, 16-25 parts of a polyvinyl alcohol solution, 16-20 parts of a plant powder, and 0.5-2 parts of a modifier; the modifier being obtained by mixing citric acid, phosphoric acid, and sodium sulfate in a mass ratio of 10:3:6.
