Abstract: The paper presents the laboratory research of lime base mortars for conservation-restoration of mural painting support situated in severe microclimate conditions. The repair mortars were analyzed from the point of view of chemically (soluble salts content), physically (water absorption, coefficient of saturation in water, adherence at support), mechanically (compressive strength) and resistance to the freeze-thaw phenomenon. The mortar test panels were then applied in situ inside of the Corbii de Piatra rupestral church (14th century), Arges County, Romania. Their behavior has been studied over a period of 6 months. The hardening of the mortars was observed by X-ray diffraction and loss on ignition. The adherence of the mortars to the mural painting support and their behavior in relation to the degradation factors (excessive humidity, the migration of soluble salts, biological attack) was also observed.
