Homokfúvással, also known as sandblasting, is a process used to clean, roughen, or prepare surfaces for painting or coating. It involves propelling abrasive material, such as sand, at high velocity against a surface using compressed air or water. The impact of the abrasive particles removes rust, dirt, paint, and other contaminants. It can also be used to create a textured finish or to etch designs onto various materials.

The abrasive material used in sandblasting can vary depending on the application. Common abrasives include sand, glass beads, aluminum oxide, and silicon carbide. The choice of abrasive depends on the hardness of the surface being treated and the desired outcome. For instance, softer abrasives like glass beads are used for delicate surfaces, while harder abrasives like aluminum oxide are suitable for tougher materials.

Sandblasting is employed in a wide range of industries, including automotive, construction, manufacturing, and art. In the automotive industry, it is used to remove rust and old paint from car bodies. In construction, it is used to clean building facades and prepare surfaces for painting or sealing. Manufacturers use sandblasting to clean metal parts and create specific surface textures. Artists utilize sandblasting to etch designs onto glass and stone.

While effective, sandblasting can pose health risks if proper safety precautions are not taken. Inhaling abrasive particles or dust can lead to respiratory problems. Therefore, it is essential to wear appropriate personal protective equipment, such as respirators, safety glasses, and protective clothing, when performing sandblasting. Ventilation is also crucial to minimize dust exposure.
