Resin crazing over acrylic paint

General Discussion
1

So to keep it brief, I’ve covered up/repurposed a resin swirl I wasn’t happy with by painting over the hot coat with MTN94 white. The paint appeared to take quite well and had 44 hours to cure (albeit in the cool damp UK climate) but when applying resin pinlines this evening the resin has started crazing, not quite sure yet whether the paint or resin is reacting, or if perhaps the paint is still gassing off.

Has anyone come across this before? Obviously I’m hesitant to do the gloss coat in case it has the same issue and wastes a load of resin.

You painted over the entire board?

If it was me, I’d sand the paint off before next coat of resin. Looks to me like the two don’t play well together.

Not the entire board, but a good portion of the deck, supposedly the resin and paint ought to be compatible but it would seem not.

Be glad you found out now

Montana (the paint you used ) isn’t good for that.
You should use only “water based” marked paints.

Hello i used Montana regular cans and it happened the same.

Now Montana has water based spray cans ( they cost double the price of regular cans). But they worked very good.

I used posca acrylic markers and they were ok also.

Cheers and good waves

Yep, regular Montana.
After sandig and then glassing.

Still there is a way to correct it that i did and worked that was after the final sandig of the board i painted on top of the mistakes and sprayed some varnish to match the hot-coat.

It worked, now lets see if it lasts???
