What is Marmorino plaster?
Marmorino plaster is a mixture of aged lime putty and marble dust or marble meal. Proportions vary, but generally 1part Lime Putty – 1 part marble dust (or meal). Traditionally there could be added ingredients like linseed oil or olive soap, but often marmorino is just polished/sealed with those.
The term “marmorino” simply denotes that the aggregate is marble dust/meal instead of sand in “intonaco” plaster. Intonaco (direct translation “plaster”) as a term that refers to the top layer of plaster. So marmorino is intonaco and intonaco is marmorino. Both made with main active ingredient – Slaked Lime Putty. So you can paint straight on it as it is a Buon Fresco.
