Sand on the wall is a common problem, which not only affects the aesthetics, but also affects the service life of the wall. To solve this problem, applying a concrete hardener is an effective solution.
Concrete hardener is a special water-based coating that can penetrate into the interior of the concrete surface to form a hard, wear-resistant, waterproof protective layer. It can not only improve the hardness of the wall, but also prevent problems such as sand and cracking. With the use of concrete hardeners, the appearance of the walls will be smoother and cleaner, while also extending the life of the building.
The walls need to be treated before the concrete hardener can be applied. First of all, you need to clean the dirt and oil stains on the wall to ensure that the wall is dry and dust-free. Then, a concrete hardener is used for coating. When appliing, it should be applied in a certain order to ensure that the painting is uniform and there are no omissions. During the painting process, you can add an appropriate amount of water to dilute as needed, but not too much so as not to affect the effect.
After the painting is completed, you should wait for a certain amount of time for the concrete hardener to fully penetrate into the inside of the wall and dry. During this time, any contact or friction on the wall should be avoided so as not to damage the protective layer. When drying, the wall will become harder, smoother, smoother, and have good waterproof properties.
In conclusion, applying concrete hardener is a simple and effective solution, which can effectively solve the problem of sand on the wall and improve the hardness and waterproof performance of the wall. It is not only suitable for home decoration, but also for occasions such as commercial buildings and industrial plants. If you're having a sand on the wall, try applying concrete hardener!
