Bai Hua introduced four kinds of stone prevention methods

In the use of wet cement to install landscaping stone, especially after crystal care, renovated ground, often with white Chinese returning the phenomenon. Light as a mist that can be used to erase neutral detergent; then form a layer of heavy frost, use steel wool polish before crystallizing agent is removed, and will soon appear; there will be more severe stone tile superficial punctate off, or slag along the pattern lines jumped off the block, or exhibit chalking blotchy sheet.
In the formation of white stone in China, which factors were similar traces of water spots, plus a lot of water due to the direct cause of the alkaline metal ions, which are produced by Bai Hua, wherein the alkaline water After the dissolution of metal ions, then direct penetration into the stone due to the crack sealing or untrue place among the stone surface, thereby further form of stone Bai Hua, therefore, in the installation and construction of which should be possible to prevent moisture and alkaline metal ions penetrate into the stone material, the following is a few precautions: http://www.stonegroupon.com/
1, due to the need before the installation of stone construction requirements is required or even five or six front surface protection works, in order to prevent the use of stone or cement them because the groundwater in the water into the stone structure itself were to go, plus cement alkaline metal ions penetrate, causing Bai Hua.
2, the choice of stone sealant, should choose the stone sealant material, construction and in operation in the correct way to carry out the construction, in order to prevent the caulking between Bai Hua generation.
3, for the stone laying of the cement mortar, we need to use some low water-cement ratio of cement mortar, and need to add a reducing agent, in order to reduce excess moisture in cement.
4, multi-use some non-polluting aggregate, provision should avoid the use of sea sand, sea sand because among the metal ions such as sodium, calcium and magnesium are more crazy, in order to reduce aggregate among the metal ion source, and requires cement mortar waterproofing agent added, this method avoids ingredients are dissolved metal ions and thus a lot of water to penetrate into the stone being.
