Hey all,
So my customer is asking me if I could plaster a inset wall nook? It is hard plastic with a toothy surface. It has a half dome curve towards the back , and of course the edges are trimmed. I have two questions #1 Is there anythng special I need to do prep wise? Or can I just hit it with Firmonovo? #2 I want to keep as much of the original form as possible. At the same time I want that Rasa Calce cracked look. Well I be able to achieve that look with a thinner application of plaster?

Thanks,
Simon

Good question for Trained Applicator forum Simon. Also you can search archives, there are a lot of RC questions there.
