Abstract
Ethyl silicate has been used with good success in the consolidation of adobe surfaces in the past 20 years. Since the treatment is irreversible, some concern about its behaviour in time is justified. To control the modifications of the treatment, SEM pictures were taken at various time intervals, from one day to 16 months. These pictures show progressive reopening of the pores, with temporary formation of filaments of the polymer crossing the cavities. Globuli of silica gel progressively reduce their volume with completion of the reaction. This study will continue in the future.
