How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Home of paint news: 1 Construction technology of art stone paint of artists 1 Base treatment 2 Scraping and leveling putty 3 Spraying art stone paint primer (black bottom or same color

finish 2 Construction guide of art stone paint Step 1: the base surface treatment procedure because the condition of the base surface is directly related to the construction quality of the art stone paint of meticulus, therefore, the base surface must be carefully inspected and accepted before decoration The specific requirements are as follows: 1) for the new wall just built, it needs to be fully maintained and dried; for the old wall which has been peeled by moisture, it needs to do the bottom layer plastering again, and then a series of spraying construction of "Maxus" liquid granite (colored paint) can be carried out 2) The base surface shall be flat and clean, free from oil, floating ash or other pollutants 3) For the old paint on the old wall or other base surface, its adhesion shall be confirmed by test; if the adhesion is poor, it must be completely removed Base acceptance standard: 1 Surface flatness: generally, it is required that the dislocation is less than 3mm If it exceeds this range, it is necessary to polish it to make it flat 2 There is no delamination, hollowing, surface layer crack, wind crack no more than 0.2mm, no obvious sand hole and other defects 3 The surface layer shall be of high-grade plastering, that is, the perpendicularity of the production surface shall not be more than 3mm, the surface flatness shall be less than 2mm, the perpendicularity of the internal and external corners shall be less than 2mm, and the squareness shall be 2mm 4 The surface must be flat, clean, uniform in color, free of cracks, obvious joints, dust, oil stains, exposed steel bars, iron wires, sawdust, red corners and gray lines, straight and square, clear and beautiful 5 The angle protection shall meet the construction specifications, and the width and depth of the separation joint (strip) shall be uniform, flat and smooth, and the edge angle shall be neat, horizontal and vertical 6 Alkalinity of base course: the pH value of base course wall is lower than 10 7 Moisture content of base course: the moisture content of base course is less than 8%, and the newly painted mortar surface course can only be constructed after about 3 weeks 8 Surface dirt: the dust and oil on the surface shall be removed with wire brush and synthetic detergent, or polished with coarse abrasive cloth, and the construction can only be carried out after cleaning and polishing Step 2: apply leveling putty, polish and level (1) apply putty with trowel, scraper or steel batch, from top to bottom The putty shall not be applied too thick every time, which is easy to crack, fall off and other defects Generally, a layer of external wall putty is about 0.5-1.0mm (2) Putty is usually applied twice The interval between two times of putty shall not be too short After the first putty is dry, the second putty shall be applied (3) When applying putty, do not apply it back and forth too much, so as to avoid curling, falling off or extruding the rubber in the putty, and the sealing surface is not easy to dry (4) When applying putty, pay attention to the technique, press the blade tightly with the index finger, press the putty into the defect, fill and fill it up, clean the putty around, and minimize the traces of putty (5) After the putty is completely dry (generally 12 hours in sunny days), polish it with corresponding sandpaper and clean the dust Step 3: clean up the dust on the wall before painting the construction art color stone paint primer (black bottom or low color), evenly spray a layer of primer on the base surface, and carry out the sealing treatment, so as to prevent the base surface from seeping color and moisture, thus polluting and swelling the main material of art color stone, affecting the construction quality When spraying the water-based sealing primer, a special spray gun shall be used The air pressure of the air compressor shall be more than 4kg The center of gravity of the gun mouth shall be vertical to the wall, and the distance between 30cm and 50cm shall be evenly sprayed back and forth twice After spraying, there shall be a layer of oil light The water-based sealer will dry for about 12 hours Step 4: according to the design requirements, the groove and seam shall be leveled and measured on the wall, the line shall be snapped with the ink cartridge, the position shall be set, and the masking paper shall be pasted for protection Step 5: during the spraying of real stone paint modeling, the texture modeling shall be made according to the design effect, generally the real stone paint modeling, evenly spray the real stone paint according to the requirements, and dry for 24 hours Refer to the construction process of real stone paint Step 6: when spraying the matched solid color primer, use a special spray gun The air pressure of the air compressor should be over 4kg The center of gravity of the gun mouth is vertical to the wall Spray it back and forth evenly for two times at a distance of 30cm-50cm The second time can only be carried out after the first time is completely dry Because the color of solid primer has a great influence on the final effect, it is necessary to ensure that the spray color is the same, and it is not allowed to drop spray or thin spray Step 7: spray the main material of art color stone paint Check that the matching solid color primer is uniform and dry Use a special spray gun to spray the main material Select the muzzle (2.0mm, 2.5mm, 3.0mm) according to the particle size Select the muzzle diameter The air pressure of the air compressor should be more than 6kg Adjust the pressure of the pressure cylinder to a proper level and maintain a stable oil output Depending on the pattern of the sample plate, adopt oblique spray or direct spray The distance is 40cm-70cm Cross the gun back and forth at a uniform speed to ensure uniform full spraying If the pattern density is relatively high, it is not recommended to spray at one time, it can be divided into two times If the spray is dense at one time, it is easy to flow and hang and make bubbles of color spots Step 8: after the main material layer of the art color stone varnish finish is completely dry (generally dry in 24 hours in sunny days), the finish can be sprayed The air pressure of the air compressor is required to be more than 4kg The muzzle of the spray gun is vertical to the wall, 30cm-50cm away, and evenly sprayed back and forth The finish is generally sprayed twice First, spray a thin and even layer without leakage So far, all the construction procedures of the art color stone paint of "meticulus" have been completed 3、 Precautions for construction of art color stone paint 1 Please select a professional construction team of art color stone paint An experienced construction team plays a key role in the project quality 2 The quality of base treatment and putty layer has a significant impact on the final decoration effect and performance The construction of the next process can only be started after the previous process is qualified 3 The ambient temperature below 5 ℃ will affect the composition and structure of water-soluble coating before solidification, so it is not suitable for construction under this temperature condition (according to the construction requirements, the "Maxus" art color stone paint after the completion of the construction shall be subject to the national standard of freezing and thawing test - 40 ℃) When the temperature is lower than 0 ℃, the product is strictly prohibited to be stored in the open air, and shall be stored in the room above 0 ℃ Construction shall be avoided when the humidity is above 80% 4 When the wall pH is more than 10, hydrochloric acid water or oxalic acid water shall be used for cleaning, and then clean the wall with clear water until the wall pH is less than 10 before construction 5 Uniform construction and bottom covering of colored primer are the premise to ensure the overall effect 6 Before the construction of art color stone paint, it can be slightly stirred or poured, but it is not allowed to cut at high speed and dilute with water 7 Special spray gun shall be used for construction Before construction, test coating shall be carried out on the test board, and formal construction shall be carried out after confirming the color and shape 8 The coating quantity of main material directly affects the coating quality and decoration effect Too much spray will produce sagging and blurred pattern Too little spray will lead to scattered pattern and low performance index of coarse coating 9 Supporting products include: sealing primer, super weather resistant real stone paint, colored medium paint, finishing coat, which must be used together 10 When multiple spray guns are used to spray the same wall at the same time, the same type of "nozzle" shall be selected to make the floating point of each spray basically the same, otherwise, the overall effect will be affected 11 The construction of art color stone paint must be carried out in the final stage of decoration works to avoid contamination or damage of the coating when it is not dry 12 The distance between the bottom of the constant pressure tank and the suction pipe is too short, which will cause the main material particles to be damaged when they are pressed out It is advisable to check that the distance between the bottom of the constant pressure tank and the suction pipe is 5mm before use 13 If the construction personnel do not have the construction experience of art color stone paint, they should be trained intensively and master the construction essentials before independent construction 14 Before construction, calcium silicate board or plywood shall be used, and the effect shall be confirmed according to the template made by the process, which can be used as the reference for construction comparison 15 During construction, do not over thick or uneven construction When multiple construction personnel are working at the same time, each person should have a reference plate for comparison to avoid construction errors of different personnel 16 After the completion of the construction of the reference plate, check the overall effect If there is any penetration or leakage, carry out spot spraying construction and repair 17 When the temperature is low, it is normal that the viscosity of the coating will increase 18 Take good care of your construction tools to avoid affecting the construction effect due to unclean or damaged tools 19 The best time for outdoor construction is when the weather is good; if the weather is cloudy or there is a possibility of rain, the construction effect of spraying will be affected if the wind speed is too high 20 In case of heavy rain during spraying, if the surface of art color stone paint has not been sprayed with finish paint, the constructed part must be covered to prevent rain washing If it is washed by rain, it is necessary to rework and repair it according to the extent of damage Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating,
