In the construction of water-wrapped water facade, how to achieve uniform spraying?

Engaged in external wall coating friends, many will encounter such problems, water bags colorful paint, how to spray even?
water-packed colorful paint mostly use spray guns for spraying, for construction operations, but also because of improper use of spray guns resulting in uneven distribution of the coating, let's look at its solutions.
★ The smaller the gun distance, the greater the spray pressure, the greater the impact of the product by air pressure, water coating will appear unequidated, resulting in the problem of oversized thick;
the spray fan surface and the painted surface appear in a vertical state

. When manually manipulating the spray gun, the spray width should not be too large, otherwise there will be uneven coating problems. Spray gun operation should always be parallel to the painted surface, vertical with the spray fan surface, the operating rate is unstable, the coating thickness is uneven, the running rate is too thin coating, the running rate is too slow coating is too thick.
★ in the use of spraying equipment, to do the right strength, the right distance can be, so as to get the desired coating effect. After the construction, some sweeping things also need to be perfected, paint and help utensils to clean up, after the use of residual paint to block and retain, this is a problem to be paid attention to.
construction tools
grinding machine, special spray gun, air compressor, steel blade, scraper, wallpaper knife, putty board, textured paper, rollers, oil brush, pen, sandpaper and so on.
main materials
external flexible putty, closed primer, water-wrapped water colorful paint base coating, water-wrapped water multi-color paint coating, water-wrapped water multi-color paint and so on.
Construction order
According to the spraying process of water-wrapped water multi-colored paint, the order is: grass-roots treatment - scraping external wall flexible putty - closed primer - bullet line stickers (according to design requirements) - object protection - spray water multi-color paint coating - stroke (according to design requirements) - mask paint - local dressing - Clean up the site - acceptance of completion
construction method
(1) wall cleaning: first of all, the use of hoe and so on to hit the base (whether there is an empty drum), shovel to the floating layer, to ensure that the base is solid, found that the empty drum place immediately completely eliminate the original wall until the bottom, found that the civil construction batch layer has empty drums must be eliminated. The use of grinding machines, angle grinders and other portable grinding equipment to polish the grass, requiring the grinding plain has paint on the surface of the floating sand burrs.
(2) scrape putty: use external flexible putty to scrape the wall, requiring the corners straight, the wall flat.
(3) bottom coating construction: flexible putty completely dry, brush once the bottom coating, uniform, requires uniform color without flowering phenomenon.
(4) finished product protection (bullet line sticker): according to the requirements and construction surrounding environment, the necessary wall protection measures, need to paste the bullet line paste of the paper.
(5) large-sided spraying: after the upper process is completely dry, water can be sprayed colorfully. Strict control of sufficient spraying, requiring continuous uniform spraying, to prevent excessive flow hanging, just in place can be conducive to improve molding quality, to ensure a stable pattern, smooth feel, delicate smooth.
(6) Timely unmasking: timely grasp of the multi-colored paint coating after the drying of the film table in time to remove the glue strip, repair local damaged parts, to prevent human damage, to ensure that within 24 hours to protect the film. Pay close attention to the weather changes before and after construction to prevent rain erosion.
(7) mask paint: the main coating is completely dry (generally takes about 24 hours) to carry out cover paint construction, can be sprayed, brushed and rolled.
(8) to check the quality of construction, local quality problems for dressing work.
(9) The tools that have been constructed should be cleaned in a timely manner.
