If you are a stone conservation worker, in the attitude of professional ethics, you need to take a closer look at the choices and precautions for the stone curing agent that Shi Dafu gave you:
Because the development of stone in the country is relatively late, there is no normative standard, and the brand of stone curing agent is also a variety of species.
Because different curing agents have different price points. Therefore, when you use the stone curing agent, you can choose the corresponding stone curing agent according to the different installation process, the variety of stone and the environment where the stone is located. To ensure the quality of the stone maintenance project, the inevitable condition is to choose the stone curing agent correctly. If used indiscriminately, not only will it not achieve the expected results provided by the customer, but it will also be a problem and a serious problem.
The choice of stone curing agent, the first point: you need to choose according to the customer's requirements for protection, the purpose of protection is to prevent alkali, rust. Another comprehensive waterproof and anti-staining ability. So for the first one, you need to use silicone type stone curing agent. For the second type, an organic fluorine type stone curing agent is required. For example, Shi Dafu's organic fluorine type stone curing agent works very well.
The second point: consider from the perspective of the structure of the stone. For example, a stone like a large white flower needs an oily stone curing agent. This is because the solvent component of the oily stone curing has a strong ability to penetrate and can penetrate deeper into the stone for protection. For the general stone water stone curing agent on the line.
The third point: Consider the use of stone. The first type, for example, in a restaurant, stove, driveway, or easily contaminated place, then Dr. Shi suggested that you use an organic fluorine-based wipe curing agent, because this curing agent can improve the anti-fouling ability of the stone surface, and use The anti-staining ability is particularly strong. The second type, for example, is a silicone-based curing agent. The reason for the selection is that the product is particularly resistant to UV and acid and water.
Fourth point: Consider from the perspective of the installation process of stone. If the person is wet mounting method, Shi Dafu once again recommends that you use the special curing agent for the bottom surface. The bottom side of the stone is protected from the side. The bottom surface needs an alkali-resistant stone curing agent, and does not affect the bonding degree between the stone and the cement.
The fifth point: consider the customer's likes. The surface of the rough surface stone is processed into a film line. Such a large project requires a film-forming stone curing agent made of silicone as a raw material, even if it is as follows: this product has good hardness, high bonding strength, and is resistant to ultraviolet rays. It is not easy to use acrylic-based ground. Sealant (film forming type), this product is mainly designed for the bottom seal. Then pay attention, if you use it on the surface of the stone, there will be peeling and discoloration.
Sixth point: From the point of view of the color of the stone, consider whether it is a stone with a deeper color. Because the stone is prone to discoloration after using the protective agent on the stone, the choice of protective agent is required to be tested.
Precautions for the use of stone protectants When using stone curing agents, do not blindly look at the instructions. All need to be tested.
1. Don't just look at the product's manual. Any product must be tested on-site to determine if it is optional.
2. When selecting the product, do not be easily blinded by the surface water-repellent effect of the product. The surface effect is only temporary. If the residual part of the surface is removed, the test will be the real effect of the product.
3. When selecting, pay attention to whether the stone curing agent will change the color of the stone after use, whether the surface residue is easy to remove, and whether it affects the brightness of the stone surface.
4. The construction process is one of the important criteria for the selection of stone curing agents. If the process is too complicated, it will directly lead to an increase in cost.
5. Do not use oily stone curing agent in closed places. Poor air circulation may cause poisoning.
6. Glossy stone is recommended not to use film-forming stone curing agent, because the surface is too smooth will affect the bonding fastness of the curing agent.
7. Do not blindly pursue low cost and small loss, quality first, price second is the primary principle of using stone curing agent.
The protective effect of any stone curing agent is relative, so the choice of products should be based on actual requirements and effects, correct construction, and enhanced post-maintenance to achieve the best results.
