A Hardener or Blast Room, also known as a blast chamber, is a dedicated space designed for abrasive blasting processes. These rooms are used to clean, prepare, or finish surfaces of various materials, including metals, plastics, and glass, by propelling abrasive media against the surface at high velocity. This process is essential in industries such as automotive, aerospace, manufacturing, and shipbuilding for surface preparation, rust removal, paint stripping, and creating surface profiles for coatings.
