Stone maintenance and construction are generally carried out on dry boards. Therefore, in the rainy season, since the rainy season brings various troubles to the stone maintenance and construction, it is urgent to solve the problem of stone maintenance and construction in the rainy season, and it is also the dream of all construction units. problem to be solved. So, how to maintain the stone in the wet weather in the rainy season? Let's take a look with the editor of Fabulous Group

　　1. Compared with the maintenance and construction of dry stone, wet stone has certain defects. The net-like protective layer formed by the curing agent on the surface of the pores inside the wet stone is not as dense as the net-like protective layer formed on the surface of the pores inside the dry stone. , The protective effect is relatively weak, but it can shorten the construction period and improve the site utilization rate in the rainy season, so it has been recognized by many construction units.

　　2. When renovating the exterior wall wet by rain, you can use the strong penetrating emulsion stone curing agent for several times (at least 2 times) after the exterior wall stone surface is slightly dry. For wet stone with water spots, it can only be cured by washing, drying and then brushing.

　　3. Water spots are the deliquescent saline and alkali inside the stone, and these deliquescent saline and alkali will absorb a lot of water in the air, resulting in obvious wet marks on the surface of the stone. No matter how the outside weather changes, these wet marks are all can't be done.

　　4. When dealing with this kind of board, because the surface of the stone is alkaline, it can be cleaned with an acidic cleaning agent to neutrality, and then the surface of the stone is forcibly dried quickly and cured with a solvent-based fast-curing stone curing agent.

　　5. The maintenance and construction of stone in the rainy season has also been well resolved. Now let’s talk about some specific countermeasures and plans for the maintenance and construction of the stone in the rainy season.

　　6. From the principle of stone maintenance, the curing agent reacts with the ionic water in the stone. The amount of water on the stone surface has no necessary effect on the curing reaction of the curing agent in the pores. For dry stone, its curing reaction is slow, and the formed curing layer is not as dense as the dry board.

　　7. Sometimes the amount of water in the pores of the stone is too high. If a solvent-based curing agent is used, the solute cannot enter the pores of the stone, and the ideal curing effect cannot be achieved.

　　8. If the general stone curing agent is used for curing, the salt and alkali will continue to return before the curing reaction is completed because the curing reaction is relatively slow (usually 24 hours). The solvent-based fast-curing stone curing agent has a faster curing reaction time, and the curing effect can be achieved within 15-40 minutes, and can effectively prevent all kinds of salt and alkali from returning to the stone surface again, so as to achieve the effect of long-term prevention and control of water spots.
