Coating technology: ceramic color sand coating construction technology

Core tips: 1 Application scope of ceramic sand coating process: The coating process is applicable to the construction of sand wall coating process on the indoor and outdoor bases such as cement mortar, mixed mortar, plastering gypsum, asbestos cement board, concrete board, cast-in-place concrete, wood plywood, fiberboard, gypsum board, old coating, etc 2 Ceramic sand coating process: Base treatment → base repair → primer application → main coating application → protective finish 3 Operation method of ceramic sand coating process (1) Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Coating home news: 1 Application scope of ceramic sand coating process: this coating process is applicable to the construction of sand wall coating process on indoor and outdoor base layers such as cement mortar, mixed mortar, plastering gypsum, asbestos cement board, concrete board, cast-in-place concrete, wood plywood, fiberboard, gypsum board, old coating, etc 2 Process procedure of ceramic sand coating: base treatment → base repair → bottom coating application → main coating spraying → protective finishing coat 3 Operation method of ceramic sand coating process construction ① base treatment: first remove dust and other adherents on the surface of base Knock out or polish the raised part to be flat; the empty part shall be dried again after knocking out The dislocated part of the joint and the large depression shall be filled with polymer cement mortar; the steel mortar that hinders spraying shall be removed to fill the holes; the floating slurry, loose and powdered part of the surface shall be removed with a blade and wire brush Remove the mold release agent and oil stain on the surface; repair the pockmarks, holes and cracks on the surface with cement putty Wash the wall with zinc sulfate solution or dilute hydrochloric acid solution when the wall is alkaline and frosting, and then wash with clean water The essential base course shall be sanded with wood wool The original coating of base course shall be treated differently according to different situations: the old coating with loose, peeling and embrittlement shall be removed; the old coating with firm adhesion shall be roughened with sandpaper; the coating without water resistance shall be removed completely ② Brush primer: mix the primer evenly If the coating is thick, dilute it according to the requirements of the product manual The two-component primer shall be mixed with curing agent and diluent in strict accordance with the specified proportion, fully stirred and placed to the specified time Brush evenly with roller brush or hover brush, and pay attention not to miss the brush or brush too thick ③ Spray the main coating: after the main coating is evenly stirred, install the special spray gun, start the air compressor to control the spraying pressure at 0.4 ~ 0.7MPa (4-7kg / cm 2), open the spray gun, spray it evenly once along the horizontal and vertical directions, the distance between the spray gun and the wall is about 30 ~ 40cm, and keep the spray gun and the scene vertical during spraying ④ Protective finish: the material with ceramic composite core technology can significantly improve the durability In addition, the compact coating structure can play a superior anti pollution performance 4 Precautions: ① in order to ensure the integrity of the coating, the primer and main coating shall be preferred to the matching products; when the manufacturer only provides the main coating, the primer shall be the products recommended by the main coating manufacturer ② The construction shall be avoided in the environment with temperature lower than 5C and relative humidity lower than 85% It is also not allowed to construct in windy weather, so as to prevent the coating material from cracking due to drying too fast ③ When the primer is a two-component coating, it shall be prepared in strict accordance with the product instructions, and the amount of ingredients shall not be too much each time, so as to avoid waste caused by the curing failure of the coating The primer shall be diluted with special diluent or brand recommended by the manufacturer ④ Due to the long drying time of coating, weather forecast should be paid attention to Make construction arrangement to avoid construction before rain and snow ⑤ After the coating is dry, it shall not be immersed in water for a long time before the handover to avoid quality accidents; ⑥ the brushing tools shall be cleaned and kept properly after use Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
