Kimia S.p.A.

Since 1979, Kimia has produced a complete range of products for building restoration, recovery and maintenance. With twenty years of specialization, it can offer truly dynamic products. In fact, Kimia is constantly updating its lines of products to respond promptly to new problems related to building recovery and restoration and to keep up with the technological progress being applied in the construction field. In addition, the reliability of Kimia products has been confirmed by the worst kind of test: the architectural heritage damaged by the earthquake in 1984 and consolidated with Kimia products was not touched in the least by the earthquakes that years later - starting in September of 1997 - once again violently struck the territory of Umbria and the Marches.

Kimistone C 957


Delicate ammonium bicarbonate-based cleaner for painted surfaces, made according to the Institute for Conservation and Restoration rules. The product (created from a specific recipe used for the cleaning of stone monuments) slowly solubilises coherent atmospheric dirt and, thanks to the alkalising effect, it softens black crusts, promoting their removal. The particular formula allows to form chemical complexes with the calcium contained in the black crusts, solubilising it. The product does not alter the original patina of the stone.

Use cases

Idoneo per materiali lapidei delicati di tipo carbonatico e/o materiali lapidei a matrice silicatica, quali ad esempio: marmi statuari, marmi venati, calcari teneri, graniti pregiati. Si può applicare anche su finiture a imitazione pietra e su intonaci.


  • Effective cleaner for stone surfaces and plasters, even painted ones
