Coating technology: relief texture coating construction technology

Core tip: nano materials are used in the coating, which is tasteless, non-toxic and non corrosive According to different needs, corresponding colors and patterns can be deployed to change different decorative effects, so that the monotonous plane wall is full of three-dimensional sense and dynamic flow Therefore, relief coating is popular for its good three-dimensional texture The construction technology of relief texture coating is a popular construction method 1、 Process flow: II Construction steps: 1 Base treatment Before the base treatment, the wall needs a certain period of maintenance Before puttying, loose, peeling, hollowing and powdered putty shall be completely removed Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? 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 Coating home news: the multi-layer texture coating uses nano materials, tasteless, non-toxic, non corrosive According to different needs, corresponding colors and patterns can be deployed to change different decorative effects, so that the monotonous plane wall is full of three-dimensional sense and dynamic flow Therefore, relief coating is popular for its good three-dimensional texture The construction technology of relief texture coating is a popular construction method 1、 Process flow: 2 Construction steps: 1 The wall needs a certain period of maintenance before the base treatment Before puttying, loose, peeling, hollowing and powdered base course shall be completely removed, and then dust, oil and other pollutants shall be removed Repair the wall with external wall putty, level the first layer locally, fill the large holes and gaps with putty or filling glue, polish the part after the putty is dry, and then cover the base with putty to make the base level After the putty is completely dry, polish to make the base level Relief layer itself is concave and convex state, and the flatness of the base layer is required to be lower than that of the flat coating process, which can reduce the number of times of grinding and the degree of fineness If the putty for exterior wall is cement system, it also needs to be cured Generally, the curing time is 14 days, and the next process can be carried out only when the pH value is less than 10 and the moisture content is less than 10% 2 There are three kinds of spray relief: one component solid powder relief, one component paste relief and two component relief Among them, powder relief and single component paste relief are widely used During the construction, the spraying can be carried out by adding water for adjustment, and the curing shall be carried out at least three times after the completion of the construction During the construction in high temperature and dry season, attention shall be paid to the small amount of one time, multiple times of deployment, multiple times of water conservation, until the pH value is less than 10, and the moisture content is less than 10%, the construction of the next process can be carried out Single component paste relief is directly constructed without water dilution The two-component relief shall be proportioned according to the proportion in the product specification, and the spray construction shall be carried out after the mixture is even To spray embossed bone paste, a professional spray bucket shall be constructed, and the diameter of air outlet shall be selected according to the size of embossed bone paste points The diameter of the discharge nozzle is usually 4-5mm when the spray point is small, the air pressure is slightly larger, and the discharge is faster; when the spray point is large, the diameter of the discharge nozzle is usually 7-9mm, the air pressure is slightly smaller, and the discharge is slower; when the spray point is large, the spray bucket is vertical to the wall, and the nozzle is slightly inclined upward If the spray point needs to be flattened, when the surface of the main layer coating changes color and the surface is dry, use a smooth hard plastic roller dipped in kerosene or water to gently roll on it The roller surface is not allowed to stick with the main layer coating, and there is no pressure leakage part If the wall surface is not smooth enough, use a shorter hard plastic roller to roll, even if there is a depression on the wall surface, there will be no part that cannot be pressed 3 Brush and apply the sealing primer once after the relief is dry Generally, the sealing primer does not need to be diluted with diluent Before painting, the base course shall be polished and leveled, the floating dust shall be cleaned, and the construction tools shall be kept clean to ensure that the sealing primer is free from any pollution and sundries Generally, the construction method of roller coating is used for sealing primer, which is convenient and quick 4 The intermediate paint shall be applied once after the sealing primer is dry The construction viscosity shall be adjusted according to the product specification and construction tools In order to make the coating have a good leveling and workability, it is generally necessary to add a certain diluent to dilute the coating In general, the viscosity of the coating should be reduced and the amount of diluent can reach the upper limit of the specification In order to ensure the thickness and fullness of the coating film and prevent sagging and color paint blooming, it is forbidden to over mix the diluent during construction 5 After the intermediate paint is dry, the top coat shall be applied once One coat of intermediate coat is to reduce the comprehensive cost of finishing coat, but sometimes the intermediate coat is not used, and two coats of finishing coat are applied directly The construction viscosity of the top coat shall be adjusted according to the product specification and construction tools In order to make the coating have a good leveling and workability, it is generally necessary to add a certain diluent to dilute the coating In general, the viscosity of the coating should be reduced and the amount of diluent can reach the upper limit of the specification In order to ensure the thickness and fullness of the coating film and prevent sagging and color paint blooming, it is forbidden to over mix the diluent during construction 3、 Precautions: 1 The construction shall be carried out at the temperature of 5-35 ℃, the air humidity of less than 85%, the substrate humidity of less than 10%, and the pH value of pH value of less than 10%; 2 During the construction, pay attention to the feeding amount, not too much or too little, so as to avoid uneven coating; 3 When painting each part, there is no pause in the middle of the process If you have to stop, you should also choose the original connection part of the house structure to avoid the connection mark 4 During the roughing construction, you can adjust the pattern according to the size of the dilution amount Generally, the pattern with small dilution amount is sharp, and the pattern with large dilution amount is round; 5 Dilute according to the dilution ratio in the product manual Do not overdo it to avoid falling of pattern 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,
