How do sandstone moldy spots?

How do sandstone moldy spots?

Answer:

The correct approach includes careful attention to transportation, storage, construction and other links. The thin panel is not only fragile, but also easy to stain. Attention must be paid to the stubborn stains, such as mortar, coating, protective coating, rust and mechanical lubricating oil.From the storage period to the end of the construction period, the stone must be covered with plastic or antifouling cover. Full understanding of the entire service process may result from contamination or human contact with internal and external pollution. Must be isolated from the pollution sources as much as possible, often to remove dirt, etc.. In contaminated areas, the use of appropriate paint and building cleaning agents to clean stains. When cleaning the stone, it should be appropriate to prevent damage to the environment and workers or to the stone itself. Taking into account the cost factor, cleaning should be economical and effective. Therefore, you must be familiar with the following:1, clean and convenient method and place;2, the loss of stone caused by the cleaning ability;3, the surface pollution;4, whether it must be cleaned.9, sandstone stone conservation five"
The plane is inclined, foreign products copestone stone, use wall cave drainage does not require part, water inflow stenosis of the structure part, the water flows through the concrete, glass and other building materials surface and flow to the surface of sandstone are easily polluted sandstone products. In special circumstances, should choose to match the nature of stone materials. For example, when used as a wall lining, it is necessary to protect the front of the elevator and the elevator, furniture, etc.. Combinations of incompatible materials are prone to contamination. For example, a car has a liquid leakage on the sandstone surface The permeable mortar laid on the bridge deck or ladder will become a coal pollution. An important reason for the seam after the wrong cleaning.
Dirt and contamination are not only beautiful, but also contain corrosive chemical elements that cause the sandstone to deteriorate. Pollution is generated during construction or maintenance, must be treated differently. Generally speaking, prevention is more important than cleaning, and the long-term maintenance effect is better than that of acute cleaning. It can be used to reduce and prevent soil stains by proper design and material selection, careful construction and maintenance. The so-called correct design, that is, to take note of the following things pollution of sandstone products:
