Reason summary 1. The causes of cracks in concrete walls are mainly the reasons for the concrete itself and the reasons for the construction process. Such cracks can be repaired by automatic low-pressure grouting. The automatic low-pressure grouting technology is a comprehensive technology for the concrete crack grouting field developed by the crack treatment center of Beijing Metallurgical Engineering, including materials, machinery and construction. After the grouting is repaired, the inside of the crack is filled with AB-1 grouting resin, and its tensile strength and bonding strength are high, and no cracking occurs again. 2. Cracks in brick masonry walls, cracks in new partition walls and cracks in walls of different materials are all temperature seams, which cannot be grouted and repaired. Because of the expansion and contraction of cracks, flexible materials should be used for repair (such as Beijing Metallurgical Construction). The A12 high-flexage joint material of the Engineering Crack Treatment Center) is an entirely new concept. Compared with the previous rigid repair, it is more suitable for crack treatment with a large amount of activity. Second, the wall crack repair method 1.

In addition, everyone should also level the uneven wall surface, the general gypsum is more common, the unevenness of the bump is not more than 0.5 cm, and then the patch. “General non-load-bearing walls such as light-weight walls and thermal insulation walls need to be patched†3. After all the above are handled, everyone must prepare to putty. The quality of the putty is related to the effect of the construction. You can use the putty with higher fineness and harder texture, or add a certain white latex to improve the hardness of the putty. After the putty is dry, everyone still needs to polish on the wall. After polishing, you must thoroughly clean the wall to avoid too much dust and affect the adhesion of the paint. 4, the last step is to paint on the wall, everyone can put a little more water when modulating the primer, so it is easier to brush evenly.
