Marble, dolomite and limestone conservation techniques

Marble, dolomite and limestone are all soft materials. So in the construction process and the future use of the process are extremely vulnerable to external pollution, exposing its poor tolerance of pollution, such as vulnerable to rain, dirt and other pollution. Compared with granite, these three kinds of stone permeability is high, more vulnerable to pollution. The best way to solve this problem is to protect it.

Now commonly used in the world is the stone for the permeability of protective agent, the protective principle is to penetrate into the natural stone inside the natural stone, deposited in the stone between the tiny particles of small particles, or attached to the stone surface of the individual mineral molecules , In order to prevent water, oil and dirt into the stone. Permeability protectants can be waterborne and solvent type, and usually contain silicon, silicone, methyl silicate or other similar silicon compounds. Permeability protectants can also be divided into two categories: waterproof and anti-oil type. Waterproof is mainly used to block water and water chemicals, such as fruit juice drinks, coffee, tea and soda water. The oil-resistant penetrating protective agent is used to prevent water and oil-based liquids from penetrating into stone, such as edible oil, grease and other oils. Anti-oil type permeability protective agent also has a waterproof function, but the waterproof products are not necessarily able to prevent oil pollution.

One of the factors to be considered when using a protective agent for protection is what type of stone is used and where it is laid. In view of the different nature of marble, limestone and dolomite, we should use different treatment methods according to the situation. For example, the daily use of the kitchen marble floor, the choice of protective agent must have anti-oil characteristics. And for the busy hotel lobby on the ground, pedestrians will leave a lot of footprints, it is easy to friction the ground, then in order to protect the surface gloss, in addition to the use of penetrating protective agent treatment, the need to apply a layer of surface Of the protective agent, and even polishing products with ground polishing.

In addition, another factor to consider is the maintenance mode. If dolomite or marble floor daily scrub, by the acidic chemical damage to the possibility of corrosion is greater. If you ignore the maintenance of the ground, dirt will be blocked in the stone pores. If the stone itself has a high brightness, the gloss may be worn. In this way, no matter how good the protective effect of the stone surface, the surface will become dirty, darker. For example, the more busy hotel lobby on the ground every day to clean the dust and scrub with water, perhaps only need to be a surface can be removed from the protective agent to deal with. But if the home into the living room, then do not need a day with a cleaning agent cleaning, with a better waterproof protective agent for the protection of it.

Finally, it is important to emphasize that any of the penetrating protectants can not form a protective layer on the outermost surface of the stone, so that the permeable protective agent is preferably subjected to a primary surface treatment, that is, a surface protective agent Stone can really be considered to be a "double protection." Because any kind of stone is not the best way to protect the wax is not waxy, waxy layer is neither breathable, and easy to sticky, easy to make the surface color of yellow stone, and the use of breathable and non-waxy material surface protection Agent, you can make stone and protective layer to be further protected, but also to keep the natural stone bright color, can be described as threefold.

Before the choice of stone, its natural bright surface is also a factor can not be ignored. However, we must ensure that the physical properties of stone is the use of its greatest value lies. Only to consider all the characteristics of stone, you choose the stone in order to maximize their decorative practicality and aesthetics.
