2 Make the shell powder and water fully dissolved (add color paste if necessary), and soak for 1 hour after mixing evenly (in the shade); 3 Check the prepared shell powder coating before use If there are shell powder particles that are not fully dissolved after soaking in the coating, grind them by hand, and use them after mixing evenly 4 The prepared materials shall be used immediately within 2 days Because the materials are not suitable for preservatives and other auxiliary materials, the temperature can be kept below 25oC for 48 hours If the shell powder coating stinks or precipitates, the coating cannot be used continuously Art 1 Bottom layer a: pour proper amount of shell powder coating into the seasoning container according to the material proportion (unit: kg) of the coating area, add the proportion of water (unit: kg) of the corresponding coating method according to the proportion of roller coating and spraying materials in the proportion of the ingredients, and mix it fully for 2 to 3 minutes; B: make the shell powder and water fully dissolved (add color paste if necessary), mix it evenly and soak it for 1 minute Hours or more (in the shade); 2 Texture layer a: pour appropriate amount of shell powder coating into the seasoning container according to the proportion of materials used in the brushing area (unit kg), add clean water (unit kg) according to the proportion of materials used in bullet coating in the proportion of ingredients, and mix it for 2 to 3 minutes; b: make shell powder and water fully dissolved (add color paste if necessary), and use it after mixing evenly Note: according to the different construction process, the construction process shall be increased appropriately 04 construction method before construction notice 1 Paste paper tape (masking paper or color separation paper), for the door, window frame, furniture and paint connection, paste paper tape protection, different color junction, use paper tape, newspaper or plastic bag to do a good job of protection; 2 Color matching, wall with color requirements, should accurately calculate the area in advance, once the materials used are evenly distributed; 3 Painting construction sequence: first ceiling, line, and then wall Before roller coating construction, ensure that the base material wall treatment and putty layer construction of the coated wall have met the requirements Note: if there is a phenomenon of exposed bottom (wall leakage black) on the base wall, the exposed part can be partially painted with putty powder or shell powder paint, and then the first overall painting can be carried out 1 After the first painting, check the flatness of the wall If there is any problem, use putty powder or shell powder paint to make up the surface (spray appropriate amount of clear water on the putty powder wall before the first painting is better); the interval between the second painting and the first painting is more than 2 hours (the surface is dry) 2 During roller coating, the coating on the roller shall not adhere too much, but shall be evenly stained (with the help of tray or grid), the rolling speed shall be moderate, the pressure shall be uniform, and the key to the quality of roller coating is to receive the slurry; on the painted surface, the roller can be repeatedly rolled several times to produce fine and beautiful patterns 3 Where the roller fails to roll or is missing, it shall be repaired with special roller or plate brush Before spraying construction, ensure that the base material wall treatment and putty layer construction of the painted wall have met the requirements Note: if there is a phenomenon of exposed bottom (wall leakage black) on the base wall, the exposed part can be partially painted with putty powder or shell powder paint, and then the first overall painting can be carried out 1 Before construction, strictly check whether the doors and windows, furniture, wood floor and other objects are well protected; when allocating materials, it is necessary to allocate them according to the product's water distribution proportion; first prepare a test board, adjust the discharge amount of the spray gun and air pressure; when spraying, move your arms and feet to keep up with your hands and eyes, and deal with the problems in time; When spraying, do not increase or decrease the moisture proportion of the paint (adjust according to different process requirements); 2 The determination of spraying sequence and route affects the whole spraying process; before spraying, determine the spraying starting point and spraying sequence From the general layout, follow the principle of "first far, then near, first up, then down, first inside, then out" Generally, spraying can be carried out according to the principle of first ceiling, then wall, first indoor, then aisle and stairwell 3 The spraying is divided into two times, the first spraying interval is 2 hours (before the first painting, it is better to spray appropriate amount of clear water on the putty powder wall); after the surface is dry, spray the second time Airless spraying: spray gun diameter 517 or 521, spraying pressure between 120 and 130pa 4 Airless spraying, the distance between the spray gun and the wall is 50-60cm Air spraying: the diameter of the spray gun is 2.0-3.0mm (selected according to the requirements), and the pressure is more than 8 atmospheres 5 The distance between the spray gun and the wall is 30-40cm 6 After spraying, the pasted protection shall be cleaned immediately Elastic coating construction 1 The texture size and effect of elastic coating are mainly adjusted according to the needs of customers For the texture of large color, the diameter of the spray gun mouth can be increased for construction; for the texture of small color, the diameter of the spray gun mouth can be reduced for construction 2 The distance between the shotgun mouth and the wall is about 1.5m, which is suitable After the shotgun is painted, it shall be dried 3 After the coating is completed, the pasted protection shall be cleaned immediately, and the edge of each pasted protective tape shall be straightened out by dipping the brush in water In order to reduce scratches during scraping and coating construction, it is necessary to mix ingredients with reference to the proportion of scraping and coating materials of the product in detail During the actual aging operation, it is appropriate to add water to avoid scratches; during scraping and coating construction, when polishing putty, the selected sandpaper shall be finer and the wall surface shall be flat and smooth; generally, more than two times of painting are required to achieve better results No matter roller coating, spraying, elastic coating or scraping, the oil and ash brought in during construction shall be removed immediately Tools cleaning roller, plate brush, tray and other tools shall be cleaned immediately after use to extend the service life of tools 05 after the completion of cleaning, the floor and windows shall be cleaned immediately to remove the protection and leave the clean space to the user 06 precautions please read the construction instructions in the product packaging carefully before use to obtain reliable and satisfactory coating effect 1 The putty powder used for the foundation wall shall match the shell powder, and the shell powder coating manufacturer shall designate the putty powder or special putty powder for shell powder coating 2: This product belongs to water-based coating, please do not mix it with solvent based coating during construction; 3: the prepared materials shall be used immediately within 2 days (because the materials do not contain preservatives and other auxiliary materials, the temperature can be kept below 25oC for 48 hours, if the shell powder coating stinks or precipitates, the coating can not be used continuously); 4: Open all doors and windows as much as possible before operation and use to ensure that the construction area has sufficient ventilation conditions; 5 In order to maintain the cleaning of the construction site and ensure the best coating effect, please effectively separate and cover the important areas such as furniture, doors and windows, and do a good job of protection;
