Properly applied Artenova Veneziano plaster will have no problem in exteriors with harsh weather and/or acid rains.
Just check the substrate conditions before and that's it.

Dear Boston,

I wouldn't trust anything but SAFRA (Artenova) products, especially outside. Pretty much anything you buy here in the US is an extended version of an interior latex paint. BAD NEWS all the way around, especially outside. If you are into plasters, check out our school, we do AMAZING stuff with the real thing!

Luca, have you applied stucco veniziano Artnova outdoors in the Northeast. Let me know. I had a client who thought of doing her cabana in a veneziano. Parick

Hey Pat!
I know that people have used Venzi on columns and surrounds in an exterior environment. Would the entire cabana be surfaced in Venzi? There is a lot of prep work to build the proper substrate, but I am sure it can be done.

You can do a cabana with Veneziano Patrick!
