Painting Over Gelcoat

Not only do you want the paint job to look good you want to preserve that shiny gelcoat like surface.

Painting over gelcoat.

I had thoughts of just sanding with 330 to rough it up and the put on 2 3 coats of awlgrip. 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. Unlike wood fiberglass surfaces are nonporous making them unsuitable for spray paint adhesion. Do i need to prime it if the under original coat is pretty good.

One is just in front of the stern seat and the other four are equally spaced to just aft of the bow seat. For smaller surface areas like a chair apply the gelcoat using a paintbrush using short vertical strokes. I ll look into the interlux paint. As for the core i m not sure what you mean.

I am painting over an old 10 years awlgrip paint job. What it has are five ribs about 3 wide. The color is also the same. Yes you can apply gelcoat over a surface that s already covered with gelcoat.

And gelcoat over large areas is a ton of sanding not fun. 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. With a bit of work and a fair amount of care you can achieve your goal. You ve cleaned compounded and waxed and it looks good for a while but the chalkiness returns maybe the red accent stripe that used to look so good looks pink or the dark blue bootstripe is now baby blue.

Thanks for the reply. If so then it s time to think about refinishing the gelcoat.
