A process for the treatment of a porous inorganic material e.g. stone, comprises contacting the porous inorganic material with a single phase liquid mixture comprising alkoxysilane, water, organic solvent and a silanol polymerization catalyst. There is also included a liquid treatment for a porous inorganic material in the form of a single phase liquid mixture, comprising alkoxysilane, water, organic solvent and a silanol polymerization catalyst; which mixture may be supplied in the form of a pack comprising an assembly of containers which contain the various components of the mixture either separated from one another or in suitable admixture.
