Common knowledge of coating: material selection and coating structure of imitating brick paint

Core tips: the main paint for imitation brick paint coating is generally made of synthetic resin emulsion, sand wall architectural paint and deep color coating made from natural colored sand In addition, flexible water-resistant putty, alkali resistant sealing primer and waterproof, stain resistant finish are also required The main function of the sealing primer is to isolate the base surface, prevent moisture from seeping out from the base surface, enhance the adhesion between the coating and the base surface, and avoid peeling or loosening The dark primer is the dark background of the whole imitation brick paint coating, which avoids a lot of pointing work The main coating system consisting of sand wall coating and dark primer has the color and quality of imitation brick 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 Coatings home: the main paint for imitation brick coating is generally made of synthetic resin emulsion, sand wall architectural paint and deep color coating made from natural colored sand In addition, flexible water-resistant putty, alkali resistant sealing primer and waterproof, stain resistant finish are also required The main function of the sealing primer is to isolate the base surface, prevent moisture from seeping out from the base surface, enhance the adhesion between the coating and the base surface, and avoid peeling or loosening The dark primer is the dark background of the whole imitation brick paint coating, which avoids a lot of pointing work The main coating system composed of sand wall coating and dark primer has the effect of imitating brick color and texture The most outer layer of water-proof and stain resistant coating is mainly silicon-c coating, which can enhance the waterproof, UV and stain resistant performance of the coating surface, and facilitate the cleaning in the subsequent use process In order to obtain the elegant effect of the face brick, the white carbon black matting agent is added to the silicon acrylic coating After the imitation face brick paint is coated with the top coat, the hand feel is smooth and the matt effect is also obtained The coating structure (from inside to outside) is as follows: wall base course - sealing primer - putty - primer - sand wall coating - topcoat The performance requirements of the imitation brick paint system are as follows: the product name performance requirements of the main coating sand wall coating meet the requirements of JG/T24-2000 "synthetic resin emulsion sand wall architectural coating"; the film elongation rate meets the requirements of JG158-2004 "rubber powder polystyrene granule external wall external thermal insulation system" The black primer meets the requirements of the JG/T172-2005 "elastic architectural coating" Flexible water resistant putty meets the requirements of R products in JG/T157-2009 building exterior wall putty The sealing primer meets the requirements of the exterior wall products used in JG/T210-2007 "primers for building interior and exterior walls" The main physical and mechanical properties meet the requirements of GB/T9755-2001 synthetic resin emulsion exterior wall coatings The coatings home is focused on coatings, diatom mud, paint and coatings, and coating process News and information of fire retardant coating, coating, diatom mud, paint coating, coating technology, decoration knowledge and decoration effect map of fire retardant coating,
