    ABSTRACT This study evaluates the efficacy of a tetraethoxysilane used as consolidant (Estel 1000) and a nanoconsolidant based on silicon oligomers modified with n-octylamina (UCAD-2o) in two types of granitic rocks. The application of these products was carried out under different moisture conditions in the rocks, evaluating the consolidant efficacy, the changes generated in the colour of the stone and in thewater vapour permeability. Results show a higher effectiveness of the nanoconsolidant comparatively to the conventional tetraethoxysilane, confirming the advantage of the incorporation of the non-ionic surfactant to TEOS polimer. © 2014 Taylor & Francis Group, London.
