The construction process of fluorocarbon paint is different due to different spray materials. The construction process of fluorocarbon coating for exterior wall is attached.
Grassroots requirements
1. The quality of the base layer of plastering and concrete shall comply with the "JGJ Building Decoration Engineering Construction and Acceptance Specifications".
2. There shall be no dirt on the plastering layer or concrete surface layer (including the split seam, around the window frame, etc.).
3. The surface of the base layer must be firm and free of looseness, no cracks or shelling, flatness ≤ 2mm, no dust on the base layer, no adhering particles.
4. Plastering and concrete base coating exterior wall coatings require moisture content
The paint room for fluorocarbon paint should not be more than 10%, the PH value should not be higher than 9, the new plaster cement mortar wall should be maintained for more than 10 days in summer, more than 20 days in winter, and the cast-in-place concrete wall should be maintained for more than 21 days in summer. It takes more than 28 days in winter.
Base surface treatment
1. Check the flatness of the wall surface, the large protrusions need to be sanded and leveled, and the large depressions or holes are filled with cement mortar and smoothed.
2. Cut the large crack on the wall, and fill the high-elastic putty continuously for several times until the wall is flat, and the putty is smoothed after drying.
3. Use a brush, blade or sandpaper to remove debris from the wall and remove the loose cement layer on the wall.
4. The processing requirements are in compliance with the flatness requirement ≤ 2mm.
5. The wall surface is basically clean, no dust, no sticky particles.

1. Special anti-cracking putty for fluorocarbon paint: special for fluorocarbon paint anti-cracking putty
Chlorofluoroethylene-vinyl acetate type fluorocarbon coating formulation
[1] Additive: water = 20; 1; 8 ratio of putty, the putty must be fully stirred by hand drill.
2. The maximum standing time is 4 hours. It can't be used for more than 4 hours. The cured slurry can't be used. Check the surface of the wall for dirt and other contaminants. It should be cleaned up.
3. Use a two-meter-long aluminum alloy to scrape the putty by the ruler, firstly scrape it once, then scrape it once, and the running speed and force should be balanced by the ruler. Otherwise, it will form a wave shape in the direction of the ruler movement and affect its flatness. .
Tetrafluoroethylene-vinyl ether type fluorocarbon coating formulation 4. Paste the decorative tape, divide the boundary strip as required, put the putty on the boundary, and then tear off the tape one by one.
5. Putty is generally embedded in 4-5 times; 6. The putty layer is dried (generally not more than 4 hours) and then sanded.
The special putty for fluorocarbon paint is too long, the putty is hard and hard, it will be difficult to sand (was waste of manpower and sandpaper), the rough and greasy surface must be completely polished, otherwise the subsequent construction will waste a lot of putty.
6. It should be sanded with 120 mesh or 150 mesh sandpaper.
7. After the putty is polished, the unevenness of the wall surface should be completely eliminated, and the straight angle and waist line should be straightened.
