• Hull Jet is usually applied directly over suitable primer. In maintenance situations, Hull Jet may be applied over sound epoxy system after confirming adhesion of the existing system. Consult Flosil-BET Coatings for guidance.
• Hull Jet can be a 2 coat system. Care must be taken to avoid hard dry of the first coat before application of the second coat. Second coat must be applied as soon as solvents have evaporated from the first coat, i.e. first coat is in touch dry condition.
• Hull Jet film must be free from defects such as dry-spray and over spray. In such cases, any rough surface must be sanded down and a thin coat of Hull Jet may be applied.

Systems and Compatibility

Following primers are compatible with the system:

AQUA MASTIC, AQUA ST, AQUA ST-03, AQUA SEALER

Possible Applications

• Marine Vessels - Steel, Wood, Fiber, Etc...
• Power Stations’ Sea-water Intake Areas.
• Fast Boats and Yacht – Rudders and Keels.
• Sea Chest
• Sea Chest Screen
• Chain Locker
• Jetties

Air Temperature	5-50°C
Substrate Temperature	5-60°C
Relative Humidity	50% minimum, 85% maximum
Surface temperature shall always be at least 3°C above Dew Point. Do not expose the coated articles where there are chances of condensation on the surface.

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.
