Over the past 20 years, the possible usage of disperse and colloid systems of organic
consolidation agents as well as mineral systems with particle size in nanodimensions in the context
of cultural heritage care has been examined. Nanomaterials, with particle size of up to 1μm whose
properties are at a certain intersection between properties at the level of molecules and mass are
the subject-matter of extensive scientific research for their positive physical and mechanical
properties such as high chemical efficiency, excellent plastic, consolidation and diffusion
properties, low sintering temperature, cleaning capabilities and others. Nanomaterials whose
consolidation efficiency has been tested by experimental research, include, in particular, hydroxide
nanodispersions. The article summarises basic conditions for application and principles of
efficiency of selected nanosystems for consolidation of historic lime-based porous materials, i.e. in
particular lime-based plasters that form integral part of historic buildings
