Maintenance Of Waterjet Coatings - Hamilton Jet HJ212 Installation And Service Manual

Installation and Service Manual
Re-application of Antifoul over existing Antifoul
Trilux antifoul may be applied directly over old Trilux in good condition. This can be done after thorough
cleaning/degreasing and light abrading of the old Trilux. Abrasive hand pads (Scotch-Brite) or wet sanding is
an acceptable way of abrading the old Trilux.
Use of alternative Antifoul
Alternative antifouls may be used provided the paint manufacturer has documented that the antifoul is
suitable for use on aluminium substrate. Foul release coatings (such as International Intersleek) have been
successfully used on jet boats, however these need to be applied as a complete paint system.
Trilux can be over-coated with most other makes of antifoul, refer to the manufacturer's specifications and
recommendations for application.
Do not apply copper oxide based anti-fouling paints.
Do not paint over the anodes.
