WATER-BASED COATING COMPOSITION FOR THERMAL INSULATION OF CONSTRUCTION SURFACES, METHOD OF APPLICATION OF CONSTRUCTION SURFACES, AND PART KIT FOR CONSTRUCTION SURFACE SURFACE COATINGS

摘要

The present invention relates to a water-based coating composition for thermal insulation of building surfaces. wherein the coating composition comprises in the range of 55 to 90% by volume, preferably from 60 to 80% by volume of hollow microspheres, 1 to 30% by weight of a dispersed acrylic binder polymer, in the range 0.1 to 3% by weight of thickener, in the range 40 to 80% by weight of water and in the range 0.05 to 5% by weight of additives selected from the group consisting of biocides, defoaming agents, surfactants, dispersants and combinations of two or more of these, wherein the coating composition is substantially free of non-hollow metallic and mineral fillers, It is substantially free of hydraulic binders and the coating composition has a density of less than 500 kg / m3. The present invention further relates to a method of applying such a coating composition using a grooved spatula to apply a grooved coating layer and a non-woven fiberglass sheet to soften said layer; and a kit of parts comprising such coating composition, a non-woven fiberglass sheet and a notched trowel.
