What level of preparation over drywall is required?
A level 3 finish (tape + mud) with the application of a water-based primer to even-out suction throughout. • Is it Venetian plaster? Venetian plaster is a generic name commonly used in Northern America to describe a smooth texture that may as well be achieved with a paint or glaze coating applied in thin layers and burnished to a marble-like texture. Real stucco or lime plaster lends itself to a surface of absolute mineral nature difficult to match with faux paint.
