Abstract

Preserving sandstone, esp. natural sandstone, is effected by treating stone surface with an acid aq. soln. contg. alkaline earth and Al salts of formic and/or acetic acid as well as heavy metal ions. Pref. stone surface is treated subsequently either with an aq. soln. contg. H2O2 and an alcohol, esp. isopropanol, or consecutively with first an aq. H2O2 soln. and then with an alcohol.
