Exterior wall sandblasting construction technology

1, exterior wall sandblasting is a popular name, but it is actually exterior wall real stone paint (a kind of coating), which has the texture of sand grains after spraying.

2. Real stone paint consists of primer, texture paint and topcoat.

3. Construction method: Apply the primer evenly, and seal other mottled walls; Sandblasting (spraying textured paint): compressed air is used as the power to form a high-speed jet beam, so that the sprayed materials are evenly attached to the primer to form a sand feeling. Top coat covers the surface to protect the color of texture paint from oxidation.

4. In addition, sandblasting treatment can be carried out before priming, such as initial pollution and roughening: compressed air is used as the power to form a high-speed jet beam, and gunning materials (copper ore, quartz sand, emery, iron sand and Hainan sand) are sprayed on the surface of the workpiece to be treated at high speed, so that the appearance or shape of the outer surface of the workpiece surface changes. Due to the impact and cutting action of abrasive on the workpiece surface, the workpiece surface obtains a certain cleanliness and different roughness.
