Crazy Crazing Paint -- Help!


Glidden is box store crap paint with a parent company in Holland or something. Akzo Nobel, actually.

Buy paint from a paint store.


Actually, the Duo is a very good product (39% volume solids, it is a premium)- it is not an economy or commercial grade of paint. The Gripper is fine for the prime coat. If there is a thick application, poor air flow, this can cause sagging or cracking. I agree with Ric's sollution to correct this.

Oh really?




I had never heard the issue of different temperatures and possible paint problems. I wonder if that was the problem I had when I used Glidden Gripper. Put the primer up late summer [warm], brought the paint out of the [cool] basement and used it. Cool paint, warm wall = problem?

Hiya hyunelan...

In my earlier post, I probably should've explained things a little better than I did...Cool product, warm walls can certainly contribute to the problem of crazing - relatively rare for it to occur over a prime film that has had ample curing time, but it can happen. What's probably more common (and this is the part I left out) is if a prime coat, or two, is applied to a surface - and cooler temps set in during those critical first few hours of curing - the coating can feel dry to touch, and it'd make sense to continue with the finish application after waiting the necessary time as described on the label. Unfortunately, in this scenario, the film hasn't cured enough to be impervious to the solvents (water & glycol) of that newly applied finish. If the prime coat, which has had some interruption to curing, absorbs some of finish product's vehicle into it's film, the prime coat will then expand - Meanwhile, the solvents from the finish coat begins flashing off as they're supposed to, and the finish film constricts. Therefore, expanding prime film + constricting finish film = crazing.

Most people know that latex paints shrink as they dry - brush out some latex on a sheet of notebook paper and observe. In the example of crazing, this dynamic won't change - the prime coat doesn't have to expand much (microscopically) for the crazing to occur. Crazing won't happen as often with lesser quality flat paints 'cause the film is so perforated by the pigments (unless the paint is applied way too heavy). It's usually more apt to be noticed in higher sheened or higher quality products.

I hope this hasn't confused anybody...sometimes my lack of articulation comes off as non-sensical ranting.

Crazy Crazing Paint -- Help!


ric, your theory might make sense in this case. When I applied the primer, it was over two hot, dry days, about 80 degrees. The next day it rained and then, uh, snowed (Utah spring is weird as hell) and two days later when I applied the top coat it was only about 65 degrees.

The only thing that doesn't make sense is that I waited two days before applying the top coat over the primer. That should have been enough time to cure, but maybe with the temperature swing it wasn't.

In any case, as the top coat has set, the crazing is less noticeable (it never really cracked, just crazed), and it was never very thick (I apply reasonably thin coats) so I think I can probably get away with sanding it lightly in a few days.

Thanks very much for the help.
