International Paint Problems

[Narcosis]

Just painted my newly made console (epoxy resin & glass cloth over marine ply) using International Pre-Kote(primer), and then 2 coats of International Brightside . 5 Days later it still has not set hard, my finger nail can dent or even rip into the surface. I am starting to panic

I followed all the drying and overcoat times on the tins.

Has anyone got any ideas about what to do? I don't want to strip and start again. Has anyone experience some thing simliar.

Here's hoping some one has a trick up their sleeve.

Thanx
D.

From what I remember back in the dim distant past my dad painted his yacht with international and it took nearly 2 weeks to go fully hard. Don't quote me on that though-it WAS 25 years ago.

Heat and light can help - not too much of course!!! Try a 500w halogen lamp.

I'm just about to do the very same thing, I'll let you know if I have similar problems. Unfortunately I can't suggest anything other than phone international. Apparently their help line is excellent.

How did you get the glass smooth before painting? I'm having a lot of issues with my fairing compound (resin with glass bubbles) being "cloggy" and very difficult to sand down in places...have had to resort to gently scaping it off with a chisel!

Have already rang them, and they blamed my resin coating saying the resin had not set yet(Last resin coat about 4 days before painting) and that the resin was still sweating. . Not sure about that nuget of info.

I had a quite a few tiny bubbles, but they sanded off (electric sander) quickly, but did you use a roler or brush to put resin coats on, and I also found that if I mixed to larger batches of resin the mix was getting thick so by the end of each resin lay the layer was holding the bubbles rather than releasing them. I used a smooth glass cloth with about 4 resin coats applied using a small short hair roller, and in most places the surface produced a mirror finish, but what c*cked every thing up was the slow drying time on the paint which seemed to attract loads of insects which left the prints when they went for a walk on my drying console. I did a quick test after on a piece that had been cut out of the console, but I did not use Pre-Kote, and its drying alot quicker I think.(2 coats of brightside)

Resining went like a dream, painting has been a nightmare.

Good luck with your painting, let us now how you get on.

Narcosis,

Did you managed to get your brightside to go off?

I've got another 3-4 layers to go, but it seems to be going ok so far.

Its getting better, it has hardened up alot, in most places I can't scratch it. Watching and hoping but so far so good. I have taken advice and done some tests and found that the pre-kote on grp slows down the dry process. I might apply a resin coat later in the season just to give me the finish I want. (Resin with pigment and fine paste to remove the clearness)

I also think that I was covering with a tarp overnight whilst drying and that might have increased the damp/humidity.

Hope yours goes better.

Did mine the same way recently: pre-kote and then Brightside. It does harden up over time; did mine about a month ago now:

Hello...
I just finished using the interlux brightside primer "Pre-Kote"
after 60 hours of prep work on a hull. I filled and sanded small
blemishes with interlux "Watertite", and sanded the entire hull with
120 and 220 (and 320 for the "Watertite" areas). I then used the
Fiberglass Solvent Wash 202 to clean the hull. We primed it with
Interlux "Pre-Kote" (rolled and tipped). It has been 7 days now and
the primer is not dry. It is dry in spots (where it was thin) but any
places where it was thicker cannot be sanded. I can use my thumbnail
to take the primer off. I see others are having the same problem...so is the solution to wait till July...(I wish I was joking)

Thanks....Fred

The pre-kote i did was over painted after about 3 hrs drying on one of the sunny days we've had. Two brightside coats where painted on, but it took a total 3 to 4 weeks before it stopped being scratch proof. It has now set very well, but it has slowed my project no end.

Next time, resin with colour pigment.
