Abstract The present invention provides a set of compositions for imparting color to cementitious or mineral substrate surfaces, comprising: (a) a composition comprising (i) an acid that has a pKa of less than 6; (ii) a weak base, wherein the conjugate acid of the weak base has a pKa less than 7 and greater than the pKa of the acid; and (iii) one or more metal salts capable of imparting a color when the composition is applied to a cementitious or mineral substrate; and (b) a radiation curable protective coating composition.
