We need to use special protective agents to protect the stone during installation, and to protect the bottom of the stone. The stone bottom is used to paste the stone on the base of the semi dry mortar. Keep the stone joint space was smooth, caulking treatment, avoid wet or damp washing.
Many of the marble paved room, regardless of the ground or wall, after a period of time will always lose luster, rough, erosion or hair surface, is the product of the cement mortar under alkali silica reaction. Therefore, it is absolutely necessary and far sighted to do the stone protection.
According to the characteristics of marble stone and the needs of customers and customers, we will make different construction plans. During construction, workers should construct according to the different degrees of stone lesions.
The marble in the pavement is due to the operation of the construction and the different effects of stone and other external effects on the stone later caused by the various diseases:
1, Baihua: because the cement mortar contaminated the surface of the stone without cleaning in time, which caused the cement mortar to harden completely, so it was easy to stay on the surface of stone and affect the effect of stone decoration.
For marble, white and cement residues are often difficult to clean, because the chemical composition of marble consists of calcium carbonate (CaCO3) and oxides such as Baihua and cement residues. Therefore, no matter what kind of cleaning agent will affect the surface of marble, the early stage of white marble can be removed by scrubbing. After the cleaning of white marble on stone, seal up all the gaps with sealant. Then use high quality curing agent to protect the surface and crevice of the stone, and eliminate the stone white bloom again.
2, rust: iron containing material into the chemical reaction of iron compounds and internal environment or stone material in the formation of yellow or brown patches on the surface of the stone.
We should not use non dedicated stone cleaning agent to clean stones, and let stone directly contact with water and corrosive environment. We should use high quality stone protectant to protect stone.
3. Water spot:
In a humid environment, the cement mortar of hygroscopic material into stone and the formation of internal real lesion.
We need to use special protective agents to protect the stone during installation, and to protect the bottom of the stone. The stone bottom is used to paste the stone on the base of the semi dry mortar. Keep the stone joint space was smooth, caulking treatment, avoid wet or damp washing.
