Different commercial mortars and stuecos used to cold restore the glazing on deteriorated tile in Seville s Plaza de España were tested for performance and durability. Five types of samples were applied to ceramic bisques and subsequently coloured and protected with resins. The samples were subjected to accelerated weathering consisting in salt crystallization, temperature and relative humidity cycles and ultraviolet radiation. Durability was assessed by visually comparing the effect of salt crystallization, determining the colour parameters with colourimetry and measuring adherence and capillary water absorption. The results obtained were used to differentiate the materials tested in two respects: stucco and protective resin performance under the environmental conditions prevailing in the Plaza de España on the one hand and colour stability on the other.
