Abstract
Of all the problems associated to contemporary painting, the most complex is probably that which
concerns powdering matte surfaces, both for their technical characteristics and optical properties
and for the aesthetic significance associated to these types of finishes. These pictorial surfaces are
technically complex due to the high risk of irreversible alterations associated to the appearance of
the treated surface and the potential for streaking, tide lines, changes in colour, darkening, added
gloss and changes in texture during the treatment process. For this study, a colorimetric analysis
was performed to evaluate the behaviour of three adhesives commonly used in the consolidation
of these types of painted surfaces, to determine the effect of ageing on the adhesives and quantify
their stability as a function of adhesive type, concentration, and application method. Of all the
adhesives, funori did not result in significant changes when aged using this method.
