It isn’t the most fun job in the world, but every so often, your boat needs antifouling in order to keep it looking its best. Here are our Top 5 Antifouling Tips:
Tape up the water line
Before you apply a coat of antifouling paint, we advise you to apply masking tape at your boat’s water line to ensure you adhere to a straight edge when applying it. It’s also a good idea to remove the masking tape and then mask it up anew with each new layer of antifouling paint you apply. This is because it can become next to impossible to remove the tape if it’s been left in place for too long.
Sand the hull
As part of your preparation before renewing antifouling, sand down your hull thoroughly to ensure you remove all cracked or flaking paint, and ensure that the surface is entirely smooth. The better the preliminary sanding work, the better result you’ll have once your new antifouling has been applied.
Wash the hull before applying paint
It’s highly important that your boat’s hull is thoroughly washed before applying any paint. If the surface is not as clean as possible, the finish won’t be right at the end, so take care of this one. Remove any present grease or contamination using a suitable cleaner before moving onto priming.
Apply two coats
When considering the question of how many coats of antifouling paint to use, you should definitely apply no less than two. It’s important not to spread the paint too thinly, as well as sticking to overcoating and immersion times as specified on your paint’s can. Make sure you stir the paint thoroughly before you begin applying it.
Apply third coat on water line
A third coat of antifouling paint is recommended for additional protection around the water line. If you have a sailing boat, then take care of your rudder and keel with a third coat of antifouling to bolster their protection too.
