The finishing plaster or smoothing plaster can be based on hydraulic binders, lime or gypsum and are used indoors or outdoors depending on the binder.
Smoothing
LC7 RASOLISCIO for example, it is used for the smooth finish, inside and outside, of lime and cement-based plasters and concrete surfaces, before decoration with paints.
On the contrary ZL25 is used as a smoothing plaster on lime and gypsum-based internal plasters; in the case of lime and cement-based plasters, these must be sufficiently cured. The use of ZL25 is not recommended in damp rooms (bathrooms, kitchens, garages) in which case we recommend the application of lime and cement-based plasters.
