  • Detail

Emulsion paint, also known as synthetic resin lotion paint, is a kind of organic paint. It is a kind of water-based paint prepared by taking synthetic resin lotion as the base material and adding pigments, fillers and various additives. It is now widely used in home decoration. As emulsion paint is a water-based paint, it has high requirements for construction and maintenance conditions. The construction and maintenance temperature is higher than 5 ℃, the environmental humidity is lower than 85%, and the maintenance time is 7 days (25 ℃), and the low temperature should be extended appropriately. So, what is the construction technology of wall emulsion paint? Now let's take a look with Xiaobian

So, what is the construction technology of wall emulsion paint? Now let's take a look with Xiaobian

construction process: base treatment &mdash& mdash; Fully apply putty twice &mdash& mdash; Primer &mdash& mdash; Two coats of intermediate coating &mdash& mdash; Emulsion paint surface spraying &mdash& mdash; Cleaning

(1) base course treatment: first remove the ash blocks, scum and other sundries on the decoration surface with a knife. If there is oil stain on the surface, clean it with detergent and clean water, and then clean the surface dust with a brown brush after drying

after the surface is cleaned, adjust the sg821 putty to the appropriate consistency with the diluent of water and vinyl acetate emulsion (mix ratio is 10:1), and use it to fill the pockmarked surface, honeycomb, holes and defects of the wall. After the putty is completely dry, shovel the excess putty with a knife first, and then polish it with coarse sandpaper

(2) fully apply putty twice: the first time shall be fully applied with a rubber scraper. It is required that the horizontal scraping is flat, uniform, smooth, dense and flat, and the line corners and edges are neat. Scrape it as thin as possible without missing, and the joint shall not be left with tenon. Be careful not to contaminate the door and window frames and other parts, otherwise it shall be cleaned in time. After the first putty is completely dry, polish it with coarse sandpaper. Pay attention to balanced operation, protect edges and corners, and clean them with a brown broom after grinding

the second full puttying method is the same as the first one, but the direction of puttying is perpendicular to the front puttying. Then polish it with coarse sandpaper, otherwise it must be done for the third and fourth times. Use 300W sun lamp to illuminate the side of the wall or ceiling, polish it with coarse sandpaper, and finally polish it with fine sandpaper

(3) primer: the construction should be carried out on a dry, clean and firm surface, sprayed once, and the coating should be uniform without omission

(4) middle layer coating construction: if there is any irregularity found before the first coat of middle layer coating, fill it with putty and polish it. The paint shall be fully stirred with a portable electric mixing gun before use. If the consistency is large, it can be diluted with water appropriately, but the amount of water added each time should be the same, and the thickness should not be different. Then pour the paint into the tray and paint it for the first time with paint roller. The roller shall be painted horizontally and then rolled longitudinally to drive away the paint and flatten it. Generally, the rolling coating sequence is from top to bottom, from left to right, from far to near, from edges and corners, from small surface to large surface. The thickness shall be uniform to prevent excessive coating falling. If the roller cannot be painted to the internal corner, it needs to be supplemented with a brush, and no omission is allowed. Remove roller hairs on the wall at any time. One wall should be finished at one go. Avoid overlapping of brush marks on the joint, and wipe away the paint contaminated with other parts with clean water in time. After the first layer of coating is applied, it generally needs to be dried for more than 4H before the next polishing process can be carried out. In case of wet weather, the interval shall be extended appropriately. Then, polish with fine sandpaper. The force should be light and uniform when grinding, and the coating should not be worn through. The surface should be cleaned after grinding; The second intermediate coating is the same as the first one, but it is no longer polished. After brushing, it should meet the requirements of high-grade brushing of general emulsion paint; (if the front putty and paint bottom layer are well treated, deep brushing of this layer may not be carried out)

(5) emulsion paint surface coating spraying: due to the different base material, tooth period, alkalinity and drying degree, trial spraying should be carried out on local walls in advance to determine the compatibility between the base layer and the paint, and determine the appropriate coating amount at the same time; Before using emulsion paint, shake the container fully to make it mix evenly, then open the container and stir it with a wooden stick; During spraying, the nozzle should always be vertical to the decorative table (especially at the inner corner), with a distance of about 0.3-0.5m (adjusted according to the size of the decorative surface), the nozzle pressure of 0.2-0.3mm2, and the spray gun should be pushed forward in a zigzag manner, horizontally and vertically. The movement of the spray gun should be balanced and the coating amount should be consistent. It is not allowed to stop and move from time to time and jump forward to avoid stacking, sagging or missing spraying; In order to improve the spraying efficiency and quality, the spraying sequence should be: wall part, y column part, y pre surface part, y door and window part. The sequence should be flexible, and it should not increase repeated shielding and affect the finished finish

(6) cleaning: remove obstructions and splash materials
