Durability of nano-TiO2 coatings was investigated on a compact and a soft limestone.

Ti loss and self-cleaning ability were checked after peeling and water impact tests.

ESEM-EDS analyses and a photodegradation test of Rhodamine B were performed.

Crack-free films well preserved Ti amounts and self-cleaning performances on stone surface.

Low cohesion of the soft limestone compromised the durability of the coatings.
