Take you to discuss the cracks on the wall how to teach you how to "repair"
After completing the renovation project, after a period of stay, the home renovation will begin to have some problems. For example, cracks and even cracks may occur on the wall due to thermal expansion and contraction, swelling, shrinkage, and other factors. After cracks in the wall, if you do not repair the situation will become more and more serious, so we will be how to "repair," and how to do the wall crack ? The following Xiao Bian took you to discuss how to do this problem of cracking the wall . Take you to discuss how to do cracks on the wall Most of the wall cracking is due to cracks in the wall's cement. Most of them are not the quality problems of decoration, but are architecturally insurmountable defects. Therefore, the decoration of the wall surface treatment is particularly important, if there is a large area of ​​cracks, the base of the cracking wall surface chiseled into a "U" shape, "U" groove spacing greater than 20CM or more, and the chiseled substrate cutting hair Handle and then hang the wire mesh. If there is a wall insulation board, remove the insulation board on the wall surface, or remove the cement wall. Install a layer of gypsum board or “5 PCT board†on the outside of the insulation layer, and then do the latex paint on it. This practice can remove all irregular cracks, cracks are generally the joints between the plates, better handling. Wall cracks are mainly caused by the problem of rain leakage in rainy days. However, it is very difficult to really deal with wall decoration when it is really leaking, so we must do a good job of defense. Water-repellent powder is a lightweight dry powder that can be easily lost by wind and rain. Therefore, the protective layer must be made of reinforced concrete to prevent its outflow for a long period of time. The treatment of different wall cracks is not the same, so the prevention of wall decoration is the most important. Putty layer cracks: generally appear as subtle cracks, evenly distributed, pay attention to not the seams are lines, lines and seams are different. Insulation cracks: It is common to see irregular cracks. It is due to shrinkage and deformation of benzene board, glass fiber mesh cloth, mortar, improper construction and many other reasons. The solution should be based on the size and distribution of the cracks. If it is more serious, it is necessary to add a grid cloth or mesh cloth. If it is not serious, use a two-component soft wall body cracks: the cracks appear uneven with the change of the foundation. The distribution is due to the settlement of the wall. If it is a building that has been subject to settlement deformation and is not busy repairing, it is best to wait until it is no longer deformed. According to the shape and density of cracks, repairs must be made in a variety of ways. It can be repaired by grooving or by adding a grid cloth. High ballistics must be used. Cracking of the stucco layer: The leveling mortar is not flexible enough to show a relatively large crack, which is generally evenly distributed. With high-pull or two-component elastic putty full batch, respectively repair. Exterior wall insulation grid cloth characteristics: External wall insulation special grid cloth is based on alkali or alkali-free glass fiber woven fabric, alkali-resistant coating treatment. The product has high strength and good alkali resistance, plays an important structural role in the insulation series, and mainly prevents cracks. Because of its excellent resistance to corrosion by chemical substances such as acid and alkali, and high tensile strength in warp and weft, the profitability of the external wall thermal insulation system can be evenly distributed, and the entire thermal insulation caused by collision and extrusion of external impact force can be avoided. The structural deformation makes the insulation layer have a high impact strength, and is easy to construct and quality control, and plays the role of "soft reinforcement" in the insulation system.
