Sandblasting or bead blasting is a generic term for the process of smoothing, shaping and cleaning a hard surface by forcing solid particles across that surface at high speeds; the effect is similar to that of using sandpaper, but provides a more even finish with no problems at corners or crannies.
Sandblasting is one of the most common and highly effective methods for the cleaning and maintenance of surfaces. The restoration of surfaces is achieved by striking fine grains of sand at a very high speed through the sandblaster’s nozzle and directly onto the object being cleaned.
One of the greatest advantages of sandblasting lies its speed and efficiency. The properties of sand—including its fine grade and its makeup of small grains—make this substance a powerful abrasive. A cleaning job that would typically take hours by hand or other less effective methods is reduced to just minutes with sandblasting.
