Strengthening of historic lime plaster by dispersion of nanoparticles of calcium hydroxide in alcohol

Preservation procedure suggests the technology of strengthening of the historic lime plasters, which is based on a liquid lime reinforcing agent impregnation - dispersions of nanoparticles of calcium hydroxide. The principle is in the use of new lime consolidant which thanks to the optimal concentration of lime (10 to 25 g / l), the lime particle size from 50 to 250 nm and the absence of water allows effective, compatible and economical reinforcing treatment during a relatively short time (1-3 weeks) . Preservation procedure is suitable for strengthening of plasters that contain pores or cracks larger than 1 micron
