The contribution is focused on the applicability of alcoholic nanosuspensions of calciumhydroxide for the consolidation of porous limestones. Based on systematic examination both on laboratory specimens and real objects, various results and practical experiences are presented. A number of methods were employed to evaluate and optimize the product application, ranging from simple visual means to instrumental methods. Thus, techniques such as polarizing and scanning electron microscopy were used as well as ultrasound and colour measurements. In this way, the effects of consolidation were assessed and an objective comparison was made between different types of lime-nanosuspensions. Based on tests with laboratory specimens, the products were then applied on reference objects and their consolidation effect was evaluated.
The contribution summarizes the main results achieved in the frame of three international projects, namely Stonecore, Nanoforart and Nanolith.
