Hi, new here. Tried posting this on Contractor Talk and haven't gotten any feedback, so thought that might have been not the optimum place. A small manufactrer with a "clay-based, all natural" finish wants me to rep and apply this in my area. I've experimented, and it's easy to trowel on, easy to blend colors for ancient effects. I can paint wonderful-looking fresco effects on it -if-I use a rather dry brush, otherwise I'm lifting the finish and winding up in a mud puddle. The manufacturer says it's made of clay, pigment, and a "secret ingredient", which always makes me nervous. It's not a lime plaster, which will cure. From what I can tell, there's no binder in it at all. you just trowel it on firmly and hope no furniture or water ever touches it--although they say it's good for bathrooms. When I've troweled it over masking tape and let it dry, it just flakes off--turns back to sand or clay; doesn't hold together one bit. GREEN! It's green, it breathes, has no VOCs--but I don't trust it. I tried a clay-and-cellulose product several years back--same problems. Anybody have experience with this type of product?
