Compositions of matter for use as a roof coating are provided. The roof coating can be applied to any suitable roof of any building. When applied to a roof, the roof coating insulates the building's interior from some of the sun's thermal energy, which would otherwise radiate into the building and raise the interior temperature. The roof coating can therefore reduce energy consumption involved in cooling the building's interior. The roof coating demonstrates advantageous thermal insulation properties (e.g., low thermal conductivity) over a wide range of temperatures and when applied with minimal thickness. The provided roof coating demonstrates high reflectance, high emissivity, low thermal conductivity, low flame spread, high solar reflectance index (SRI) in the range of 100 to 120, and acts as a sealer and waterproofer, which all contribute to its desirable properties for use as a thermally insulating roof coating.

The object of the invention is a clay plaster and a method of performing the clay plaster, wherein the clay plaster comprising clay and optionally aggregates in the form of sand, organic and/or mineral fillers, characterizes in that it comprises clay in an amount of more than 40% by weight, preferably more than 60% by weight, and more preferably more than 80% by weight, and most preferably 100% by weight of content based on the clay plaster dry matter, wherein the clay is in a powder form and granular form, whereby the amount of clay powder does not exceed 80% by weight of the granular clay and optionally comprises a mineral and/or organic filler in an amount of not more than 60% by weight, as well as possible modifying additives, additives increasing the adhesion to the substrate, additives delaying the time of granular clay soaking, retention additives and/or pigments, wherein the amount of additives is not more than 10% by weight based on the clay plaster dry matter and the method of performing the clay plaster according to the invention consists in rapid mixing of the dry ingredients of the clay plaster with an aqueous solvent immediately prior to its application to or during application onto the substrate. Thus mixed clay plaster, before the clay grains soaking in and humidity homogenisation, is immediately applied onto the substrate prepared as for other mineral plasters, resulting in a good adhesion to the substrate after drying. Preferably, the clay plaster is applied onto the substrate after having applied a bonding layer in the form of clay slurry onto a dry substrate first.

There is provided a gypsum composition for a drying type coating material, the gypsum composition, when made into a gypsum-based coating material by addition of water, capable of forming a coating film in which color unevenness is suppressed even though the coating film is thin and smooth. This gypsum composition for a drying type coating material contains hemihydrate gypsum having a mean particle diameter of 50 m or less, calcium carbonate having a mean particle diameter of 50 m or less, and a setting retarder, wherein the gypsum composition has a content of calcium carbonate of 100 to 400 parts by mass and a content of the setting retarder of 0.1 parts by mass or more each based on 100 parts by mass of the hemihydrate gypsum.
