paperartist reminded me about the book 'Papier-Mache Artistry' by Dona Z. Meilach. (Which is a completely amazing book, by the way.)
I got the book from my local library so I could look at some of Gemma Taccogna's older work again and was surprised to see in a caption under one of the photos that even after the piece is sealed you can add additional paper to revise the shape. It never occurred to me before that I could fix big indentations that were there even after I spackled with putting more paper over top.
From what I read I assume that Gemma used gesso, which I know is mostly glue. So my question is: Do you think that you could put more papier-mache on top of spackle as well, or do you think it will affect the plaster and it can only be done over gesso?

I don't think plaster is known for being waterproof.
Try this: prepare a small lump of Spackle, then let it dry/cure. Then immerse it in a small bowl of water. Does the lump get soft, gooey, or slimy? Does the water get cloudy? None of these are good signs. If it looks/acts stable, go for it.
Otherwise, if you seal the Spackle, then apply more PM over the sealer, it may work.

Hi CatPerson,
Spackle and plaster are two different things, right?
I don't see why you couldn't add more PM on top. Paper is lighter weight than spackle and plaster or gesso.
Yeah, Gemma did use Gesso. We found a thick gesso that was great. It is a Liquitex product. We couldn't see anything on the label that indicated it was thick. It comes in a jar.
One student (Elena) managed to get the beautiful finish Gemma got. I asked her, too, but there is no secret, just a lot of elbow grease. I still have several pieces made with Gemma that I gave up on; at least for now.
