1. Don't just look at whether the product 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 protective 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 protectants. If the process is too complicated, it will directly lead to an increase in cost.
5. Care should be taken to use oily stone protectants in closed areas. Do not use protective agents containing benzene solvents. Moreover, if the air circulation during construction is not smooth, it is easy to cause poisoning of construction workers.
6. Glossy stone is recommended not to use film-forming stone protectant, because the surface is too smooth will affect the adhesion of the protective film layer.
7. Pay attention to distinguishing the test reports of various versions. For the time being, only JC/T973-2005 "Natural Stone Protectant for Building Decoration" standard is the only quality standard for protective agents in China. Other reference standards are non-standard tests, and the quality standards are lower than the standard for natural stone protectants for architectural decoration.
8. Do not blindly pursue low cost and small loss, quality first, price second is the first principle of using stone protective agent.
The protective effect of any stone protectant 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.
