The main principle of protection is that the effective substances in the protective agent penetrate into the interior of the stone with the solvent. After the solvent naturally volatilizes, the effective substances and the stone crystals combine to form an effective protective barrier under the stone surface. Prevent the infiltration of external and internal pollution, so as to protect the stone and prolong the life of the stone. Because the protected stone, its water absorption rate is greatly reduced, it can be said that it absorbs almost no water; as long as the water does not penetrate into the stone, there will be no pollution. Produced. The protected stone has the following characteristics: waterproof, anti-fouling, anti-ultraviolet (delays the fading time of the stone), anti-freeze, anti-dissolution, maintains the permeability of the stone, and can reduce the difficulty of daily maintenance.

From the natural weathering damage of ancient stone cultural relics to the various natural damages and lesions of building stones today, the losses are huge.
