The finishing or smoothing plaster can be based on hydraulic binders, lime or gypsum and are used indoors or outdoors depending on the binder.

LC7 RASOLISCIO for example is used for the smooth finish, inside and outside, of lime and cement-based plasters and concrete surfaces, before decorating with paints.

On the contrary, ZL25 is used as a smoothing plaster on internal lime and gypsum-based 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 it is recommended to apply lime and cement based plasters.
