The granular structure of the stones (visible in a microscopic photo with zoom-factor 200) is weakened after centuries of weathering and decay.
NANO-materials can build bridges (marked red in the electron-microscopy-photo) between the unfastened grains of the stone and replace the lost original binder.
Damages to be treated with NANO-Agents:
Thick Gypsum-crusts
Damages to be treated with NANO-Agents:
Losses and disintegration of the surface
