Buon frescoes are difficult to create because of the deadline associated with the drying plaster. Generally, a layer of plaster will require ten to twelve hours to dry; ideally, an artist would begin to paint after one hour and continue until two hours before the drying time—giving seven to nine hours' working time.
The buon fresco technique consists of painting with pigment ground in water on a thin layer of wet, fresh, lime mortar or plaster, for which the Italian word is intonaco. Because of the chemical makeup of the plaster, a binder is not required. However, some artists used lime as a binding medium for pigment to slow the drying process of the ...

It is recommended to wait 28 days before painting a lime finish wall. However this wait time can be shortened by using an oil based primer once the plaster is dry. [6]

The stacco technique, on the other hand, involves removing only the preparatory layer of plaster, called the arriccio together with the painted surface.

However, this is not how Leonardo worked, and for this reason, he chose a new technique of putting a mixture of oil and tempera paints onto a dry wall ...
