(Summary description)How many sides of stone protective agent to protect? Five or six? Stone protectant is stone protection, which means that some protective agents should be brushed, sprayed, coated, rolled, drenched and soaked, and so on, so that stone protectant can be evenly distributed on the surface of stone or penetrate into the interior of stone to form a kind of protection, so that stone can be waterproof, antifouling, acid and alkali resistant, anti-aging, anti freezing and thawing, and biological erosion resistance. So as to improve the service life and decorative performance of stone.



So how many sides of stone protective agent to protect? Before stone paving, it is often necessary to consider the problem of protection. For the protection of stone, do you need to seal and protect the bottom as well, so that it can be painted on six sides or only five sides? Is the six side protection of stone really necessary? What kind of stone protective agent can achieve the best protective effect?

The phenomenon of hollowing often occurs in the acceptance stage of wet pasted stones, especially the stones with protective treatment on the back, which leads to the failure of acceptance by Party A. In fact, there are many reasons for stone wet paste hollowing, but this does not mean that the reason for stone wet paste hollowing is that there is a problem in the selection of stone protective agent.



Before stone paving, we all suggest to protect the six sides of stone in advance: brush the stone sealant at the bottom and water-based or oil-based protective agent on the other five sides. The advantage of this is that it can prevent stone cancer such as stone alkali return and water spots to the greatest extent.

First of all, we need to know that hollowing may occur when using water-based protective agent as bottom protection. What's more serious is that when the stone bottom is brushed with water-based protective agent, the water vapor in the water-based solvent is easier to return through the stone bottom, which is more likely to cause the phenomenon of alkali return and water spots in the stone.



Therefore, the stone bottom must be protected with bottom sealant or oily protective agent, and water-based protective agent cannot be used. But on the other hand, because the stone bottom has been protected, that is, the stone bottom has a good waterproof effect, so it is certainly not firm to paste the stone with ordinary cement.

When using stone protective agent, in order to avoid hollowing during stone pasting, one way to be considered is to replace the traditional cement with strong adhesive (not only applicable to ceramic tiles, but also applicable to marble and granite stones).
