Abstract

The hardness of natural and artificial stone containing at least 10% CaCO3 is improved by applying a water solution containing at least 0À01% of one of the following: hydroxides and soluble salts of barium and strontium, alkali metal aluminates, Ca salts and alkali metal fluorides, sulphates, phosphates and hydroxides the solution being applied in such manner as to maintain the stone moist for an extended time sufficient to cause recrystallization of the smallest sized particles into larger ones. Optionally 3-20% of an agent which decomposes in alkaline solution to release CO2 NH3 can be included examples being urea, parabanic acid, allexan, allantoin, barbituric acid, hydantoin, uric acid, ethyl carbonate, urethane, NH4 carbamate, biuret, semicarbazide, hydrazine dicarboxylic acid amide and cyanamide. Humectants, e.g. glycerol, glycols or sucrose, surfactants and insecticides can also be present.
