Is any of the stuccos mold-resistant? 

We're a DIY and have been looking into Grailcoat and going to FL to train on this product.  I thought that I had read before that it was mold-resistant, but when looking at their website, I don't see that they claim that.

What product would you use?

Thanks.

Stucco is inherently mold resistant as it has no organics for mold to feed on.

Mold issues in wood and stucco houses are usually caused by the tar-paper behind the stucco combined with nailer flange window.

I would not use grailcoat have you read the other posts about them.  They have have disolved the company already once you can check sunbiz.org and look it up.  They offer a warranty for 20 years for no cracking and when it cracks they don't do anything but pass the blame on installation they have no way to cover the warranty issues that is why they had to fold the one LLC and start another.  They have financial problems and you would be lucky if they even ship your product after they take your credit card for payment.  BEWARE OF GRAILCOAT DON'T EVEN KNOW HOW THEY CAN STILL USE THAT NAME WHEN THE DISOLVED THE COMPANY.
