| Construction steps and precautions for external wall sandblasting coating |
| Exterior wall sandblasting coating is a type of coating applied through sandblasting technology, which can form a uniform and aesthetically pleasing protective coating on the exterior walls of buildings. Sandblasting coating construction usually includes the following steps and precautions: Construction steps: 1. Base treatment: -Cleaning: Remove dust, oil stains, moss, etc. from the surface of the wall. -Polishing: Polish the wall to ensure a smooth surface without loose old coatings. -Repair: Repair cracks, holes, etc. on the wall. 2. Primer construction: -Brush or spray a layer of primer to improve the adhesion between the coating and the wall. 3. Sandblasting construction: -Choose appropriate sandblasting equipment, such as pneumatic or electric spray guns. -Adjust the pressure and distance of the spray gun to ensure that the paint is evenly sprayed onto the wall. -Select appropriate paint color and particle size according to design requirements. 4. Drying and curing: -After spraying, let the coating dry and cure naturally. 5. Topcoat construction (optional): -After the sandblasting coating is dried, a layer of transparent protective topcoat can be applied to increase the weather resistance and durability of the coating. Notes: -Construction environment: Sandblasting coating construction should be carried out in a dry and ventilated environment, avoiding construction in rainy or humid conditions. -Construction safety: Operators should wear protective clothing, masks, goggles and other protective equipment to ensure construction safety. -Coating selection: Choose sandblasting coatings suitable for exterior walls, such as acrylic, silicone acrylic and other types of coatings, which usually have good adhesion, weather resistance and pollution resistance. -Coating thickness: Adjust the coating thickness according to design requirements and usage environment, usually between 0.5-1.5mm. -Maintenance and upkeep: Regularly clean and inspect the sandblasted coating, and repair it if necessary. -Professional construction: Due to the high technical requirements for sandblasting coating construction, it is recommended to have a professional construction team carry out the construction. By following the above steps and precautions, the quality of external wall sandblasting coating construction can be ensured, thereby improving the aesthetics and durability of the building.
