details, ground and electrical works have been completed and accepted 13.1.3 green environmental protection products shall be preferentially used in finishing works 13.1.4 the moisture content of concrete or plastering base shall not be greater than 8% when applying solvent based coating, 10% when applying water-based coating and 12% when applying wood base 13.1.5 the paint shall be evenly stirred before use and shall be used up within the specified time 13.1.6 the ambient temperature of the construction site should be between 5-35 ℃, and attention should be paid to ventilation and dust prevention 13.2 main material quality requirements13.2.1 the variety and color of coating shall meet the design requirements, and there shall be product performance test report and product qualification certificate 13.2.2 the bonding strength of putty used in finishing works shall meet the relevant provisions of current national standards 13.3 key points of construction 13.3.1 the base treatment shall meet the following requirements: ① concrete and cement mortar plastering base: full puttying, sandpaper polishing, smooth surface, straight line angle ② Base course of gypsum board: the board joint and nail hole shall be treated according to the design requirements, and then the putty and sandpaper shall be fully scraped and polished ③ Varnish wood base course: the surface shall be flat and smooth, the color shall be consistent, and the surface shall be free of defects such as pollution, cracks, defects, etc ④ Basic layer of ready mixed paint: the surface shall be flat and free from serious pollution ⑤ Metal base: the surface shall be derusted and antirust treated 13.3.2 general methods of coating construction: ① roll coating method: apply the paint on the base course roughly by the movement of the wool roller dipped in the paint solution according to the way of W, then use the wool roller not dipped in the paint solution to stick to the base course and roll up and down, left and right to make the paint solution evenly spread on the base course, and finally use the wool roller dipped in the paint solution to roll fully in a certain direction The internal corners and upper and lower openings should be leveled with brush brush ② Spraying method: the pressure of spray gun should be controlled within the range of 0.4-0.8mpa During spraying, the spray gun shall be vertical to the wall, and the distance shall be about 500mm, with uniform and parallel movement The overlapping width of two lines should be controlled at 1 / 3 of the spraying width ③ Brush painting method: directly follow the order of first left then right, first up then down, first difficult then easy, first edge and then 13.3.3 painting varnish on wooden base: the knots and rosin parts on the essential base shall be sealed with shellac paint, and the nail holes shall be filled with greasy grease Before puttying and coloring, the sealing primer shall be applied once, and then the local color matching and repairing shall be carried out repeatedly After finishing each time, the intermediate paint shall be applied once, and then the paint shall be polished after drying until the tone is harmonious and uniform, and then the finishing paint shall be applied 13.3.4 application of ready mixed paint on wooden base course: first, fully brush the oil once, and then use the oil putty to inlay and scrape the nail holes, cracks and incomplete parts, and polish them smooth after drying, and then brush the middle layer and surface layer paint 13.3.5 clean the base course with 3% oxalic acid solution first, then wash it with clear water or brush the base course with alkali resistant primer once, and then apply putty after it is dry, and then paint the surface coating 13.3.6 the middle layer coating of relief coating shall be uniform in particle size, evenly rolled with special plastic roller dipped in kerosene or water, with the same thickness, and the surface coating can only be carried out after it is completely dried and solidified The surface coating of water-based coating shall be sprayed, and the solvent type coating shall be brushed The interval should be more than 4 hours 13.3.7 the coating and paint shall be polished after the coating is completely penetrated, and the grinding shall be carried out with even force, without penetrating the exposed bottom
