This process is one of the more preferred methods of surface preparation using a mechanical means. The shot blasting is a cost effective and environmentally friendly method for preparing concrete, steel, and asphalt surfaces. This labor and time saving process strips, cleans and profiles simultaneously. Shot blasting leaves the surface immediately ready for the application of coatings or overlays, eliminating drying time and costly disposal procedures associated with other surface preparation methods. Shot blasting produces the highest bonding character of any surface preparation method and is suitable for both interior and exterior applications.
