This project is for the concrete peeling and steel root repair work of the building, which is related to the structure and appearance.
Spalling repair procedures 1. Remove the powdered area First use a hammer to knock out the peeling concrete. Please be careful. 2. Remove rust with sandpaper If there are exposed steel bars, it should not be difficult to find that all the exposed parts have rusted. At this time, coarse sandpaper can be used to remove the rust on the surface of the steel bar. 3. Apply anti-rust oil Apply anti-rust oil to the surface of the steel bars. Although red lead oil is anti-rust, it contains a large amount of toxic heavy metals, so we do not recommend its use. 4. Clean the surface with a wire brush Use a wire brush to sweep away as much dust as possible on the surface of the concrete. 5. Use repair materials (packaging materials) to repair concrete According to the ratio of 3 parts powder to 1 part water, pour ARDEX A46 and water into a suitable container and mix thoroughly. Use a gray spoon and a gray board to press and smooth ARDEX A46 at the peeling position. After waiting for 10 minutes, use a gray spoon to scrape away the excess ARDEX A46. Then use a wet sponge to clean the surface of ARDEX A46.
