How do I go about painting over freshly applied antifouling paint?

Question

Some say wetsand it down, add primer coat on the top of that then paint, some say just apply primer over antifouling and repaint while some say apply primer, resand then paint in your colour choice - what do you say?

Answer 1

You don't want to paint over antifouling paint with regular paint! It will defeat the whole purpose of using antifouling paint. The bottom of the boat only, should be cover in antifouling, to just above the water line.
I recommend using Abblative Antifouling paint, which slowly sheds itself during the boating season, leaving a fresh layer, and decreasing buildup year after year.

Answer 2

It depends on what paint you have on there now. Most of the time a good pressure washing with a light sanding does the job for prep work. Then repaint. Bottom paint is expensive so paint and then use up the rest close to the waterline.

Answer 3

Since the purpose of anti-fouling paint is to keep marine animals and plants from growing on the hull, I would expect you don't want to cover it up and only apply it up to just above the water line, then use regular marine paint above. Besides, topside paint needs to withstand the sun and weather a lot more than anit-fouling paint does

Answer 4

what type of paint and why, do you want to give it a second coat of antifouling , or do you just want regular paint over it for some reason?

Answer 5

Don't apply any other paint over anti== paint as it will not stay anti==paint is designed to slowly remover it self>Sand to bare fiberglass then paint>Not going to be a easy job and where a Suit & Resperator as the anti=p is very toxic>>>

Answer 6

I wouldn't sand that toxic paint! Fresh anti fouling paint on your boat should be good to go. What's wrong with it? That's good paint and it will ware off with time in the water.
