Pressure blast or pot blast
Open blasting
Closed blasting

Surface Preparation
Roughness – anchor profile
Cleanliness

Anchor Profile
Coating requires specific profile to ensure adhesion and complete protection of the substrate. The abrasive particles cut into steel to form tiny peaks and valleys. The depth of the profile is controlled by the size, type & hardness of the abrasive used.

For instance in ship repair the etched surface or “anchor profile” required will be about 125 microns using the grit size of 0.5 to 2.5 mm.

Cleanliness
The steel structures painting council (SSPC) has established four degree of cleanliness for blasting for removal of contaminants and loose materials on the surface
White metal blast. - SA -3
Near white metal blast. - SA – 2.5
Commercial blast. - SA – 2
Brush – off blast. - SA - 1
