Painting Over Gelcoat

With a bit of work and a fair amount of care you can achieve your goal.

Painting over gelcoat.

I am painting over an old 10 years awlgrip paint job. Thanks for the reply. I had thoughts of just sanding with 330 to rough it up and the put on 2 3 coats of awlgrip. The color is also the same.

Not only do you want the paint job to look good you want to preserve that shiny gelcoat like surface. Sounds like what i m looking for. For smaller surface areas like a chair apply the gelcoat using a paintbrush using short vertical strokes. One is just in front of the stern seat and the other four are equally spaced to just aft of the bow seat.

Do i need to prime it if the under original coat is pretty good. I ll look into the interlux paint. What it has are five ribs about 3 wide. Before you can spray paint any type of fiberglass surface you will need to employ specific preparation techniques to condition the fiberglass to accept paint or the finish will peel soon after application.

If it s a large surface such as a boat or a bathtub use a gelcoat spray gun to apply a coat over the existing coat. Yes you can apply gelcoat over a surface that s already covered with gelcoat. Like any painting project preparation is the key and in this case you will be painting over the slick shiny surface of gelcoat. Unlike wood fiberglass surfaces are nonporous making them unsuitable for spray paint adhesion.

So the gelcoat on your boat is looking chalky and faded. As for the core i m not sure what you mean.
