Mineral plasters contain almost entirely natural materials and that is why they are also called "light" or "noble". The binder in them is cement, lime or a combination of both, so they are said to be cement or lime based. They are applied mainly on mineral surfaces - lime-cement, cement and putties. They are sold in paper bags in the form of a dry factory-prepared mixture. They are suitable for obtaining surfaces with dragged or scratched structure, as well as for plasters with large and rough relief. They are suitable for both external and internal use. The size of the grains included in the plaster can be 1, 2 and 3 mm. They have the lowest price per kilogram, but this significant advantage is somewhat lost due to the higher consumption rate per square meter (from 2 to 3 kg / sq.m. Dry matter per sq.m. of finished plaster).
Mineral plasters cannot be applied on synthetic surfaces, varnishes, oil coatings and on lean, mineral or dispersed paints.
The most characteristic of mineral plasters is that they have the highest vapor permeability compared to other types and have very good resistance to ultraviolet rays. Their durability is not inferior to silicone. However, they have the lowest water resistance and are the easiest to get dirty.
They are also characterized by a rather limited color variety.
