Plastering mortar sanding and brushing concrete hardener repair is a treatment method widely used in the surface of concrete structures. This repair technology can significantly improve the hardness and wear resistance of the concrete surface, while also enhancing the waterproofing and durability of the concrete structure.
In the process of plastering mortar sanding and coating concrete hardener repair, the concrete surface needs to be cleaned first to remove the dirt and loose mortar on the surface. Then, the concrete hardener is mixed with water in the ratio stated on the instructions, and the mixed solution is evenly applied to the concrete surface using a sprayer or roller. The thickness and number of brushes should be applied according to the actual situation, and generally speaking, two to three brushes will give the best results.
The advantage of plastering mortar sand and concrete hardener repair is that it is simple, fast and efficient, and there is no pollution to the environment. At the same time, the concrete hardener can also prevent the carbonization of the concrete surface, protect the steel bars from corrosion, and improve the overall performance and service life of the concrete structure.
When choosing a concrete hardener, you should choose according to the actual situation. Different concrete structures require the use of different types of concrete hardeners, so the choice should be made on a case-by-case basis. At the same time, attention should also be paid to safety issues during the repair process to avoid safety accidents caused by improper operation.
In a word, plastering mortar sanding and concrete hardener repair is a very effective concrete surface treatment method. It can improve the hardness and wear resistance of the concrete surface, enhance the waterproof performance and durability, and at the same time, it can also prevent carbonization and protect the steel bar from corrosion. Therefore, in the future construction industry, this restoration technology will be more and more widely used.
