Consolidants of Stone – History and Present

The paper summarises basic information about inorganic and organic materials used for stone consolidation (and for consolidation of porous silicate materials in general). The main characteristics of individual materials, principles of consolidation and the advantages and disadvantages of their use are given. Historic materials are also focused on, as well as the materials used today. Special attention is drawn to organic silicate compounds and epoxy resins, which are at present the most common substances used for this purpose in restoration practise
