Can I brush latex paint on a southerly day?

You can brush latex paint on southerly days.

Construction technology: base treatment-full putty scraping twice-bottom coating-middle coating twice-latex paint surface coating-cleaning.

1. Basic treatment: First, use a knife to remove impurities such as ash and scum from the decoration surface. If there is oil on the surface, clean it with cleaning agent and clear water, and then clean the surface dust with a brown brush after drying; After the surface is cleaned, the putty is adjusted to a proper consistency with water and diluent of vinyl acetate emulsion (the ratio is 10: 1) to fill the pits, honeycombs, holes and defects on the wall. After the putty is dry, remove the excess putty with an operation shovel first, and then polish it with coarse sandpaper;

2. Fully scrape putty twice: the first time, fully scrape with a rubber scraper. Horizontal scraping requires smoothness, uniformity, smoothness, compactness and smoothness, and the line angles and edges are neat. Scrape as thin as possible, without leakage, and leave no gaps in the joints. Be careful not to dirty the door and window frames, or you should clean them in time. After the putty dries thoroughly for the first time, polish it with coarse sandpaper. Pay attention to balanced operation, protect edges and corners, and clean them with a brown broom after polishing; The method of scraping putty for the second time is the same as that for the first time, but the scraping direction is perpendicular to that of the previous time. Then use coarse sandpaper to smooth it, otherwise it must be done for the third and fourth times. Use coarse sandpaper to grind the wall or ceiling of the side view of 300W solar lamp, and finally use fine sandpaper to grind it flat and smooth.

3. Primer coating: The construction shall be carried out on a dry, clean and firm surface, and the coating shall be uniform and shall not be omitted.

4. Intermediate coating construction: If unevenness is found before the first intermediate coating construction, smooth it with putty. Before use, the paint should be fully and evenly mixed with a portable electric mixing gun. If the consistency is large, it can be diluted with water appropriately, but the amount of water added each time should be consistent, and the consistency should not be different. Then pour the paint into the tray and brush it with a paint roller for the first time. The roller should be painted horizontally and then rolled longitudinally to drive off the paint, Tu Ping. Generally, the order of roller coating is from top to bottom, from left to right, first far and then near, then edges and corners, small faces and then large faces. Uniform thickness is required to prevent excessive paint dripping. Drum can't be painted with internal corners, it needs to be filled with a brush, and it can't be missed. It is necessary to remove the rolling hair from the wall at any time. One wall should be done in one go. Avoid overlapping brush marks, and wipe the paint that pollutes other parts with water in time. After the first intermediate coating construction, it usually needs to be dried for more than 4 hours before the next polishing process can be carried out. In case of wet weather, the interval should be appropriately extended. Then, use fine sandpaper to polish, the polishing strength should be light and uniform, and the coating should not be worn through, and the polished surface should be clean; The second intermediate coating brush is the same as the first one, but it is no longer polished.

5. Due to the different materials, dentition, alkalinity and dryness of the base, it is necessary to carry out trial spraying on local walls in advance to determine the compatibility between the base and the coating, and at the same time determine the appropriate amount of coating; Before using latex paint, fully shake the container to make it fully and evenly mixed, then open the container and fully stir it with a wooden stick; When spraying, the nozzle should always be perpendicular to the decorative surface (especially at the internal corner), with a distance of about 0.3-0.5M (adjusted according to the size of the decorative surface). The nozzle pressure is 0.2-0.3MM2, and the spray gun moves in zigzag, crossing horizontally and vertically. The movement of spray gun should be balanced, the coating amount should be consistent, and it is not allowed to stop and move from time to time to avoid accumulation, sagging or missed spraying; In order to improve the efficiency and quality of spraying, the spraying sequence should be arranged as follows: the position of Y column on the wall, the position of Y pre-surface, and the position of Y doors and windows, which should be mastered flexibly to avoid increasing repeated shielding and affecting the finished product finish.
