Abstract
The invention relates to denaturation compositions for waterbase paints. These compositions are constituted by aqueous solutions containing effective amounts of at least one sulphate of iron (II), of magnesium or of manganese. To control the precipitation conditions of the denatured paint, these solutions may also contain a surface active agent which is a polyether of the form ##STR1## in which R is an alkyl, aryl, aryl-alkyl or alkyl-aryl group, containing at least 10 carbon atoms, and n and p are whole numbers of which one may be zero, n+p being comprised between 12 and 100.
