Common knowledge of coating: what are the design requirements of exterior wall coating

Core tip: the exterior wall coating is the protective umbrella of the building, which can prevent the external environment from damaging the exterior wall, thus reducing the value of the building But the exterior wall coating must match with the base material and be applied systematically At the same time, it must fully meet the design requirements The external thermal insulation system is also easy to form algae and moss Part of the stone like paint will also form cracks and mechanical damage due to the coating system itself, so water can invade The repair work must be done thoroughly so that the insulation layer can play an effective role in the long term Plaster: air permeability can resist humidity Stucco in building material preservation Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Paint Home News: exterior wall paint is the protective umbrella of the building, which can prevent the external environment from damaging the exterior wall, thus reducing the value of the building But the exterior wall coating must match with the base material and be applied systematically At the same time, it must fully meet the design requirements The external thermal insulation system is also easy to form algae and moss Part of the stone like paint will also form cracks and mechanical damage due to the coating system itself, so water can invade The repair work must be done thoroughly so that the insulation layer can play an effective role in the long term Stucco: air permeability can resist wet stucco, which plays an important and decisive role in building material preservation The most commonly used mortar is: Lime / cement mortar containing minerals, silicate emulsion mortar, polymer mortar and silicone mortar In order to prevent moisture and salt damage, and to facilitate repair, the repair mortar in P1 mortar group shows good compatibility with pure silicone composite coating It has the following characteristics: due to its high permeability of water and carbon dioxide, it has the characteristics of fast drying to prevent the formation of wet spots and efflorescence of alkali, Enough to contain the crystallization of hydrated salt products and aqueous solutions, which can be firmly attached to any substrate for easy use, the primer can be completed by brush, roller, spatula and spraying: the importance of primer in order to make the pure silicone composite paint fully play its own superior performance, it must be free of building materials The negative effects brought by itself (such as alkalinity, salts, etc.) At this time, silicone is particularly suitable for making a solid waterproof primer or penetrating primer It can penetrate into the deep layer of mineral building materials, fasten the loose sand like base material, reduce water absorption, make it water repellent, create a dry environment for the base material, at the same time, it can reduce the water and salt penetration (hydrophobic protection area), and ensure its high water gas permeability In this way, the moisture that may exist at the bottom will be removed, and the substrate can be fixed by carbonization without any hindrance In addition, the adhesion of pure silicone composite coating is also improved Organosilicon is not only effective and simple, but also does not contain organic solvents that damage the environment and personal health It can be diluted with water when used Surface coating: effective protection and beautiful exterior wall coating is not only an architectural style, but also an important protection against the impact of external climate and environment The compatibility of coating to different materials and the characteristics of coating system should be considered in the selection The chemical and physical properties of the coating are quite different due to the difference of the contained base materials The better the air permeability of the coating, the better the air permeability of the exterior wall From the perspective of architectural biology, it is suggested that the coating should not seal the pore structure of the external wall, but retain its original permeability and prevent the invasion of water Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant
