Dispersions of calcium hydroxide, Ca(OH)_2, in short-chain aliphatic alcohols were studied with the aim of establishing a new pre-consolidation and consolidation methodology for wall paintings. The choice of lime (a paste comprising calcium hydroxide plus water) as the consolidant was suggested by physicochemi- cal compatibility criteria, as lime is the original binder in the wall paintings treated. Many problems are encountered when trying to apply calcium hydroxide to wall paintings.
