How to choose the protective agent for stone

How to choose the protective agent for stone? Stone used as high-end decoration materials is now increasingly used in the construction industry, the use of stone protective agent has also won the stone industry and construction engineering recognition. How exactly should we choose stone protectants? Here’s a brief introduction:

1. Type of protective agent:

The use of stone material protective agent can obviously improve a lot of disease that stone material has, it is the reasonable way that prevents stone material to produce the disease such as water spot, rust spot, white flower, weathering, also can resist grease, dirt, dust, ink, fruit juice reasonably to wait for a variety of pollution. Stone protective agent of brand on the market today are diverse, protective effect is also different, especially now according to different purposes to develop the special function of the goods, such as specifically targeting to waterproof waterproofing agent, antifouling level strong anti-fouling agent, waterproof antifouling veneer type to appearance, to improve the performance of bonding base type. On the whole, there are two types of protective agents, water-based and solvent-based. The mechanism of action includes breathable type and film-forming type, and their effects are also different.

2. Judge the pros and cons of the waterproof efficacy of the protective agent

It should be tested by a qualified testing institution, and the same protective agent will have different effects on different stones. Therefore, consumers should conduct tests with purpose when choosing protective agent. In reality, it is usually dripping on the stone to detect the characteristics of the protective agent, because the appearance of the stone after the protection usually has a prominent waterproof effect, that is, when the stone surface drops water, it will become water droplets, and the stone surface without protection will usually absorb a lot of water. But the way these are only testing stone brush protective agent, and to better judge of protective agent and brush techniques, such as protective way inappropriate or protective agent shall apply twice stone besmear again after only can appear this kind of circumstance, but soak in water for a long will fill, also some poor waterproof effect of protective agent also has the phenomenon of surface.

3. Precautions for the use of stone protective agent:

In addition to the characteristics of the protective agent, the protection mode and maintenance process are also problems that cannot be ignored. Improper application of the protective agent will affect the waterproof efficacy of protective agent. For example, the stone material is usually required to be clean and dry before protection. Once the stone material fails to meet the requirements, the waterproof effect will be affected. Once the brush coating of the protective agent in the way of immersion, sometimes also affect the effectiveness of protection. The experiment shows that the construction method with six sides completely immersed in the protective agent is not available. These methods make the air contained in some micro pores of the stone content unable to be discharged, which will reduce the infiltration amount of the protective agent and affect the waterproof effect of the protective agent. If the stone is not maintained properly after protection, the waterproof effect of the protective agent will also be affected. Normally, the protective agent requires maintenance for 1 to 2 days after completion of the construction. During this period, water cannot be dipped and it is free from contamination. However, experiments have shown that the curing period of some protective agents is not only 2 days, and some start to take effect after 2 days, and it takes more than 10 days or longer to achieve the best effect. Once exposed to water or pollutants during this period, it will still cause pollution and affect the protection effectiveness. During the curing period, increasing the ambient temperature will usually accelerate the curing process. The specific practice should be carried out in accordance with the use instructions of the protective agent.

In a word, no matter what kind of stone protective agent, only play a mitigation role in stone pollution and disease, can not prevent pollution and disease from the source. After using protective agent, the stone should still be maintained regularly, and the contaminated or diseased parts should be cleaned at any time, followed by repeated brushing of protective agent. Under normal circumstances, stone materials should be maintained once in 5 years or so.
