Repainting all substrates<br />
Below the waterline<br />
We recommend new antifouling once a<br />
year for good protection.<br />
If the existing coating is intact<br />
Overcoat using the same antifouling:<br />
• Wash the surface with Pre-Clean and<br />
freshwater, remove any loose paint and<br />
allow to dry.<br />
• Apply two coats of antifouling.<br />
• See page 45 for more information.<br />
Where the coatings are damaged<br />
You may need to fill and prime first.<br />
• Wet abrade (100–240 grade paper).<br />
• Wash with Pre-Clean and freshwater,<br />
then allow to dry.<br />
• Spot prime and fill where needed,<br />
using appropriate materials.<br />
• Fair filled areas, apply more coats<br />
of primer to encapsulate the filler.<br />
• Allow to dry fully before applying primer<br />
and antifouling from relevant painting<br />
specification.<br />
Clean abraded surface<br />
Apply Underwater Primer onto prepared<br />
surface<br />
Apply antifouling over primer or tiecoat
