Sandstone relief maintenance methods which

Therefore, it is necessary to select the excellent quality of stone special protective agent applied to the stone, to prevent pollution of stone. But you know all the protective agent can not be 100 percent long-term stop pollution, so once the source of pollution in the stone must be immediately clear, to prevent the infiltration of the pores within the sculpture.
To maintain regular maintenance and care, stop water pollution source and the penetration, must regularly done protective treatment. After the application must be able to maintain the permeability of stone and waterproof, antifouling. The quality of the protective agent should be guaranteed, must not use the unknown protective agent, so as not to fail to achieve the protection effect, but increased the stone maintenance problems;
In order to keep the surrounding environment ventilated and dry, the surrounding moisture is too much damage to the relief. Water vapor on the stone will produce hydration, hydrolysis and carbonic acid, resulting in water spots, whitening, weathering, erosion, rust yellow, and other diseases, destroyed stone;
Sandstone relief stone - sandstone, is a porous structure of the stone, this structure makes it easy to penetrate the water. And the infiltration of water, will make the sand color uneven changes, the formation of spots, these spots will become an integral part of sandstone. Therefore, sandstone needs special care:
