Surface Preparation
All surfaces to be coated shall be dry and free from oil,
grease, dust, dirt and any foreign matter that can adversely
affect adhesion of coating. Solvent cleaning as per SSPC SP1
shall be conducted wherever necessary.
NEW
CONSTRUCTION STEEL -
Prepare the surface by abrasive blasting to Sa 2½ as per ISO
8501- 1:2007. Surface shall have angular surface profile
between 40-75μ. If oxidation occurs between the surface
preparation and coating application, the surface shall be
re-blasted to meet the specification.
MAJOR
REFURBISHMENT/REPAIR STEEL -
Substrates showing damage to the existing anti-fouling shall
be spot blasted to Sa 2½ as per ISO 8501-1:2007. Edges of the
spot blasted area must be feathered down to avoid lifting of
the coating. After preparation, surface shall have angular
surface profile (anchor pattern) of 40-75μ.
FIBREGLASS/WOOD -
Substrate shall be power sanded in order to smoothen the
texture of fiberglass and also to provide smooth transition
between the laminate edges/welds. Aged wood or old wooden boat
must be allowed to dry sufficiently before coating with the
system.
Air temperature : 5 ~ 38℃, Surface temperature: 5 ~ 45℃
Relative humidity : below 85%
The surface temperature must be at least 3℃ above the dew
point to prevent moisture condensation.
