I have noticed that so many boats when they get antifouled on the Norfolk Broads seem to get a rushed job.
Good preparation and priming is essential to ensure that the antifouling adheres to the surface.
When I antifoul, after the jet wash, the hull gets roughed up with a scotch pad, primed with underwater metallic primer and then antifouled.
I see so many boats just get a jetwash and then some antifoul slapped on.
Personally, I think this is a joke.
You would not do that with any other type of paint or substrate covering so why do it with antifoul.
I think if someone is going to the trouble and expense of having a boat lifted out of the water, then surely it makes sense to do a proper job.
So many folks tell me it's okay, you don't need any primer and I have to say, that's total B.S.
