When construct stone, due to reasons of environment, installation etc, it will cause the effect failure of the stone decoration, so must do some care job on the stone before installation. Usually use the dry slab to install, but in our country, there are many places, especially in the south the raining season is long, so the installation in raining seasons cause a lot trouble.

      If order is big, most of the stone manufacturer dry the slab in sunny day in order to use them in raining time, but this way reduce the usage of the place and increase the manpower cost. As the installation need dry stone, while most of material was put in the open air, so raining day always cause the delay of project development. And there are some stone looks somewhat wet always, but that is not caused by water, it is because the salt and alkali contain water stay in the stone pore, reduce the reflection of the stone surface, thus cause the feeling that the stone is not dry. This need some chemical way to settle it.

      In recent years, with the development of chemical technique, the capability of compound product with organic silicon is in improvement. The issue of Stone protection in raining season got well settled also. The principle of stone protection is that the active component in protection material go chemical reaction with the ion state of water contained in the stone pore inner surface, silicon atom chemical link with the stone surface, form a complicated net structure in the stone pore surface, as it is the reaction between protection material and ion state of water in the stone, so the protection measures have better effect on dry stone, if stone is wet, after protection measures, the protection net formed is not so solid and strong like that form in dry stone, and because in the pore the water content is high, the protection material can not enter into the pore, so could not reach ideal protection result.

      Now in the market, there are stone protection materials suitable for preventing moisture in raining season, they could be adopted to be used during raining season, they could be used for all kind of slabs which are wet by rain or by water, by applying the material, the stone could be installed.

      Now there are some special technique to avoid the affection on the stone installation in raining season. There is a kind of strong steep latex protection material, which is used with a set of device, it has a long square shape steep trough, assembled with all kind of cutting machines, it has a rack behind for airing also, the protection material drop from the stone could come back to the steep trough.

      The operation: put the wet slab or cutting slab for about 2 minutes, when the stone surface has not flowing water, put them into the steep trough for 2 minute, get them out and put them on the airing rack for about 2 minutes, and they are ok. Its principle: during the steep, the  the silicon atom and the silicon oxygen alkyl are pressed into stone pore to react with the ion state of water, thus to form a protection net which have the function of protection. With this method, help to solve the installation problem during raining season, save time save space occupation, improve the economic benefit.

      When retread the wall which is wet, could brush the strong steep latex protection material on the wall surface twice when it is a little dry. (at least 2 times), while for some wet stone which contain water spot, have to wash it and then bake , brush. Water spot contain deliquescence salt and alkali, and they will absorb the water in the air, cuse the obvious wet spot on the stone surface, and the wet spot is always wet whatever how the weather change, so to process stone contain this kind of water spotj, could use the acid detergent to wash it, and then bake the stone quickly, after that use the rapid solidified  stone protection material to protect it. As if it could not be solidified within 24 hours, the salt and alkali will appear again. While rapid solidified stone protection material could react fast, 15-40 minute could reach the protection purpose. Effectively prevent the salt and alkali to appear again, thus to prevent the water spot for long time.

      The protection function on the wet stone is not so good as that on dry stone.  The protection net formed in the wet stone pore is not so solid and not so density as the dry stone. But in raining season, it could save time and space, so it is still widely used to apply on wet stone.

      With the development of the stone protection material technique, the properties for the protection material will be stronger and stronger, function will be improved day by day.
