The construction process of water-based sand paint for exterior walls
There are also strict restrictions on the pressure value : the water in the sand paint should be poured into a pressure tank, the cap should be tightened, and then the air pipe should be connected. At this point, the valve should be adjusted to the appropriate range. Generally speaking, the pressure of the pressure tank should be adjusted between approximately 1 and 1.2. After adjustment, push the pressure regulating valve inward to lock it.
Whether you are spraying with water into sand or water into water, the same spray gun can be used. When you spray water into sand, you need to generateAlways choose a colored spray gun with a caliber of 3.5 to 4.0. If you spray water with water, it should be slightly finer, and you can choose a 3.0 caliber colored spray gun.
Detailed information:
1. Flatness inspection: First use a 2m ruler to check the base surface and eliminate any obvious concavities. The convex parts are marked with colored pens.
2. Spot repair: hollow parts should be cut out, obvious holes or depressions should be repaired with cement mortar, and inconspicuous places should be filled with putty.
3. Sanding: Use a grinder to grind obvious protrusions and repaired parts to ≤2mm.
4. Dusting and cleaning: Use brushes, dustpans, etc. to eliminate adhesiont dust floating on the wall. When renovating a large area of wall, do a good job of pretreatment. Metal studs that protrude from the wall should first be removed from the rust to avoid contaminating the painted surface in the future.
5. Positioning pop-up line: Position the separation seam according to the drawing or requirements of Part A. For a separation seam with a width of 2.0 cm, it is necessary to use an ink line to appear. a positioning line with a width of 1.6 cm.

The construction process of water-in-sand paint for exterior walls is as follows:
Tools/materials: putty, scraper, primer, textured paper, roller brush, water-in-sand spray gun, sandpaper.
1. First of all, all pollutants, greases, foamsand other substances present on the cement surface must be cleaned.
2. The putty is scraped off. Putty usually needs to be scraped twice, the first time for leveling, and the second time for completeness. The second time, you have to wait until the first time is 80% dry. How are you.
3. Apply the primer with a roller to prevent wall discoloration caused by alkaline substances seeping out of the wall.
4. Apply the textured paper. Once the primer is dry, apply the textured paper as needed and press gently.
5. Roller coating for the middle coat usually requires two coats of roller coating because there is concern that the color will be inconsistent and uneven, revealing the background.
6. Spray the colored dots. Colored dots are usually sprayed in two batches. Once dry the first time, spray the second time with a sand spray gunand filled with water.
7. Finally, the job is done. Sand the painted surface with sandpaper to remove sharp corners and raised gravel.
