Grandezza is a metallic coating which is used to create high-quality, individual designs for indoor walls and ceilings. Diverse spatula techniques produce metallic smooth and effect designs. The Grandezza metal spatula is heat resistant up to 200 °C and can be applied to, for instance, fire places. The rusted metal look is designed with a steel spatula and a sparsely coating rust spatula.

The coating is applied as a creative technique, for instance a rusted steel look, applied with a basic spatula in thin, long tracks without structure. After drying the whole surface is coated with a steel spatula. The following day the rust is added as an activator, in a 2:1 mix.

The appearance of the finish is used for unique surfaces, and extraordinary metal look, high-quality, individual decoration. There is the possibility for combination with Volimea wall coating, by the same producer. The material is heat resistant up to 200°C.

Depending on customer requirements, after drying the surface can be sanded wet or dry the next day, to achieve more intensive spots of steel-brass metallic lusters. The material won an honourable mention in the 2013 reddot design awards.
