Cleanliness & Roughness

Abrasive-blasted surfaces are characterized by two kinds of information that are both essential but fundamentally different, although sometimes mistaken for each other: cleanliness and roughness. Cleanliness reflects the degree of presence of undesirable residual contaminants on the surface, whereas roughness refers to the micrometric shape of the surface, called the surface profile.

Cleanliness refers to sandblasting used to refurbish buildings, cleaning of boat hulls, bricks and concrete work. Sandblasting which is also known as blast cleaning is used for cleaning industrial as well as commercial structures. Glass sandblasting is roughness case.
