Between used and already verified technologies for the reinforcement of plasters mainly
include nanosuspension containing nanoparticles of calcium hydroxide and nanomaterials based on
magnesium hydroxide and barium carbonate [1]. Individual lime nanosuspension, which consists of
nanoparticles of calcium hydroxide, are dispersed in an alcoholic environment and they differ from
each concentration and type of alcohol. When the material is cured, carbonatation occurs, as well
as in the case of fresh plaster, where the calcium hydroxide reacts with atmospheric carbon dioxide
to produce calcium carbonate. Due to the deposition of calcium carbonate in the damaged material,
occurs re-strengthened ties and its hardening. The undoubted advantage of the consolidation of
plaster using nanolime is the low number of impregnation cycles, where after a few applications
nanosuspension occurs to the reinforcement of degraded material.
