Stone maintenance is mainly divided into two types: cleaning and protection. The main principle of protection is that the effective substances in the protective agent enter the interior of the stone with the solvent. After the solvent is naturally volatilized, the effective substances and the stone crystals combine to form an effective protective barrier under the stone surface. Prevent the entry of external and internal pollution, so as to protect the stone and prolong the life of the stone. Because the protected stone has a greatly reduced water absorption rate, it can be said that it absorbs almost no water; as long as the water does not penetrate into the stone, the pollution will also be reduced. There is no way to produce it. The protected stone has the following characteristics: waterproof, anti-fouling, anti-ultraviolet (delays the fading time of the stone), anti-freeze, anti-dissolution, adheres to 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 loss of composition is huge. Learn how to take effective precautions to prevent and control these damages and lesions to the greatest extent possible. , becomes more and more important.
