It is advised that you water-sand your antifouling with 80-120 every year, before applying your antifouling. This will remove the hydrolysed resin from the old paint, improve the adhesion of the new coats and the glide of the boat.
If you notice cracks or other “weaknesses” on your hull, it means that your coating system starts to be weak. It is suggested to consider sanding back to primer and repaint a complete cycle: primer + antifouling.
Some tips and tricks:
- If you are unsure at the time of overcoating about your old antifouling type, you can apply Nautix P1 primer as a barrier coat and ensure the full effectiveness of your new coats
- Apply two coats of antifouling to ensure that you have the necessary amount of antifouling products to be effective all year round
- Nautix antifoulings are compatible with most antifoulings on the market
- Never apply a hard matrix antifouling over an ablative one
