Coating technology: colorful interior wall coating construction technology

Core tip: colorful interior wall coating is a kind of water in oil component coating It is composed of bottom, middle and surface coating It has the advantages of matte, soft, colorful, beautiful and strong three-dimensional feeling 1 Coating construction equipment The diameter of spray gun and nozzle is 2.5mm Air compressor small 2 Construction steps 1) Base course treatment the base course sprayed with multi-color paint shall have a dry surface with moisture content less than 10% and pH value less than 9.5 The surface shall be cleaned of floating ash and oil For uneven, cracked and coarse depressions Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: colorful interior wall coating is a kind of oil in water component coating It is composed of bottom, middle and surface coating It has the advantages of matte, soft, colorful, beautiful and strong three-dimensional feeling 1 The diameter of spray gun and nozzle of coating construction equipment is 2.5mm Air compressor small 2 Construction step 1) base treatment the base layer sprayed with colorful paint shall have a dry surface with moisture content less than 10% and pH value less than 9.5 The surface shall be cleaned of floating ash and oil For the uneven, cracked and rough surface of the depression, putty shall be used to fill the wall, and iron sand shall be used for low grinding Generally, "two batches and two grinding" shall be carried out Putty shall have certain strength and water resistance Special putty and alkali resistant primer shall be used for those with high requirements Generally, putty shall be made of white cement, old powder and 107 glue White cement: old powder = 8:2 Putty made of chemical paste and Shuangfei powder shall not be used In addition, for the recoated old wall surface, it shall be treated separately according to the type of old coating For oily coating layer (synthetic resin and varnish), use 0-1 × sandpaper to polish the surface For latex coating, surface dust and grease can be removed For water-soluble coating layer, hot water wall shall be used The putty should be thin, smooth and smooth 2) Cover the sprayed surface behind the external corner with plastic film and other covers for 10-20cm After the spraying surface is completed, move the cover to the sprayed surface to prevent the colorful coating surface on both sides of the external corner from being polluted by spraying, resulting in flowing, falling or uneven patterns Take care when removing the cover Do not pull up the film 3) After the putty is applied to the base course and dried, open the end of the bottom coating barrel, mix the coating evenly with clean bamboo and wood stick, but do not mix with mixer When pouring paint into plastic, wood or galvanized iron bucket, paint brush shall be used first to evenly brush the paint on the wall from left to right, from top to bottom 4) After about 1 day, mix the middle layer coating evenly, pour it into the galvanized iron plate, use the coating roller to brush the coating evenly from left to right, from top to bottom, and brush evenly while rolling 5) After another 1D or so, mix the colorful coating on the surface layer evenly, pour it into the spray bucket, spray it evenly on the wall from left to right with a special spray gun, from top to bottom, so as to form a colorful facing layer The pressure of the spray gun shall be kept at 2.5-3.0kg/cm, the distance between the spray gun mouth and the wall shall be 30-40cm, and the spray gun mouth shall be vertical to the wall, and the speed of moving the spray gun horizontally and vertically shall be uniform When moving the spray gun horizontally, the nozzle slit shall be in the longitudinal state, and when moving the spray gun once, the nozzle slit shall be in the transverse state The next working procedure can be carried out after the colorful coating of the surface layer is dried for 24h 6) When repainting the old wall, for the oily coating, after sanding with sandpaper, first apply the middle layer coating, and then spray the colorful coating on the surface For the emulsion coating, after the treatment of the base, the middle coat is first painted, and then the surface coating is painted After the base treatment, the coating is coated with bottom, middle and surface coating 3 Note 1) pay attention to the influence of climate on the coating construction It is necessary to avoid spraying colorful coating on the surface in rainy days and high temperature The construction interval of each coating layer shall be determined according to different climate Construction shall not be carried out when the construction environment is below 5 ℃ To ensure the color, luster, adhesion and durability of the multi-color coating 2) Do not dilute the paint with water or thinner 3) In winter, if the viscosity of the multi-color coating on the surface is too large, the packaging container can be heated in 50-60 ℃ hot water 4) It is forbidden to mix the bottom layer and middle layer coating 5) The multi-color coating contains organic solvent Pay attention to fire prevention and ventilation during construction 6) The spray gun and container must be washed with water immediately after use 7) Paint shall not be stored in the open Home of coatings is specialized in coatings, diatom mud, paint
