paint over epoxy

Post by Two J's »

I'm not a painter and all the ideas on here are great but confusing. I have fiberglassed the bottom of my belle isle up to the boot line with system silver epoxy. For paint a guy at Jamestown talked me into Interlux Bottomkote NT for fiberglass. My question is how long should I wait before painting over the epoxy?

Once the epoxy is cured, a day or so, you are ready to go, with sanding of course. I would recommend looking at Interlux VCR Performance Epoxy, used it o n my ZIP and have had her wet for almost a month straight, plus on and off the trailer and it is standing up amazingly.
This is my first, last and only boat build.

You should wait at least two weeks before painting over fiberglass. It is gassing out for quite a while and will ruin your paint if you apply it too soon.

Yes to 2 weeks. You can be sanding, cleaning and taping.

+1 :wink:

However, ... that time can be cut to (1) week in the summertime when day time temps are consistently over 85*.

I'd rather wait and be safe than sorry, though. :wink:

If you used a epoxy resin for fiberglassing, then use a epoxy based paint. Epoxy is always compatable with epoxy.
The long wait before applying some other kind of paint is what you get into when mixing types of products.
The guy at Jamestown recommended a paint for fiberglass.............was that polyesther fiberglass, or epoxy based?

Personally, I would get a epoxy based paint, and sand the epoxy base smooth, and paint over it while it is still 'green'. Green meaning that the epoxy is not fully cured, that way you get a complete chemical bond between the base resin and the epoxy paint.
Oak is over rated, everything about it takes extra time; then it warps, splits or checks !!! :roll:
