    Just after the putty, the reasons for the cracks on the wall are: dry shrinkage cracks formed by dry and wet changes, temperature cracks caused by temperature changes and thermal expansion and contraction, and structural cracks caused by static and dynamic loads of wall structural deformation.

    1. Remove all the original putty, then re-brush the base layer, paint again, and remember that only when the first layer is dry, can the next layer be smeared, effectively prevent cracks in the inner layer, and do not brush the wall too thick, according to the actual situation. 2. If the crack area in the house is relatively large, then it is better to find a professional master directly to come to the door, and the effect will be better.

    Reasons for this:

    1. It may be because when the putty is scraped, the next layer is applied without waiting for the previous layer to dry thoroughly, resulting in cracking, or due to the change of indoor temperature, resulting in thermal expansion and cold contraction, resulting in temperature cracks.

    2. Or it is not done well when making the wall base, or the wall structure is deformed, or it is possible that the quality of the putty purchased is not very good, and the ratio of water and material is not good when batching, maybe the operation is not very good during construction.

    3. Maybe it's too thick when scraping putty, or maybe it's not doing a good job of maintenance, such as not cleaning often, not opening windows for ventilation, etc., there are certain factors.

    There are many reasons for putty cracking, there are external reasons as well as internal causes.

    1. Dry and wet changes form dry shrinkage cracks; Temperature cracks caused by temperature changes and thermal expansion and contraction;

    2. Structural cracks caused by deformation of wall structure and static load.

    3. Use inferior quality, expired greasy, or improper proportioning.

    4. The base layer is not clean, the original putty layer is not cleaned up, and the newly bought putty powder has a relatively large grip, which cracks the original putty.

    5. The first putty is not dry, and the next batch is scraped.

    6. The putty layer is scraped too thickly.

    Many factors can cause putty cracking, and it is recommended to find a professional to take a look at the scene.

    It is very likely that the bottom treatment of the wall is not done well, and the key to the bottom treatment of the wall is putty.

    If you use traditional glue putty, it is easier to crack and fall off the wall, because the traditional glue putty only uses glue to stick the double fly powder on the wall, and the adhesive properties will disappear after the glue volatilizes for a long time, and there will be cracking, falling off and other phenomena. Moreover, the glue contains a large amount of harmful substances such as formaldehyde and benzene.

    You can choose putty powder made of gypsum-based raw materials, such as Saint-Gobain aldehyde net series putty powder, the raw materials naturally do not contain harmful substances to the human body, and the bonding properties of the gypsum crystals themselves will not crack and fall off the wall, and the service life is the same as the life of the building.

    Hope it helps you solve the problem as soon as possible!

    1. When the bottom putty starts to construct the surface layer before it dries, the surface layer is dried first, and the inner layer is still in the process of drying, and the degree of drying and shrinkage between the layers is not the same, and it is easy to crack.

    2. The putty is too thick, the internal drying is slow, and the surface drying speed is faster, resulting in cracking. When the base layer is treated, the joints and leveling materials are not completely dried, and the hardness of the interior wall putty is scraped on the top, which is easy to cause cracking.

    The thickness of the first putty needs to be determined according to the surface condition of the base layer, and the general thickness is. The first putty allows a slight needle's eye, but no bubbles; The putty should not be too thick at one time, so as to avoid excessive dry shrinkage, which will affect the firm bond between the putty layer and the base layer. When scraping and coating, the force should be balanced, and the surface of the putty layer should be smooth as much as possible, and no obvious rough surface will appear.

    When scraping and coating for the second time, it should be high and low, try to make the surface of the putty layer smooth, fill the eye of the needle, and the force should be balanced when scraping and coating, so that the surface of the putty layer is smooth and does not appear obvious rough.

    Decorating a house requires putty, which can make the rough and uneven rough wall smooth, so that the wall paint is also smooth and smooth, and the adhesion ability to the wall is also stronger. But sometimes it doesn't take long to scrape the putty, and cracks will appear. At this time, it is generally not necessary to proceed to the next step, but to deal with it as soon as possible.

    1. The base layer is constructed before it is completely dried, and the moisture content of the base layer is required to be 10%.

    2. The bottom putty is not completely dry, but the surface is dried first, and the inner layer is still in the drying process, resulting in different degrees of shrinkage between the layers and easy cracking.

    3. When the base layer is treated, if the repair material is not completely dry, apply hardness of interior wall putty on it, which is easy to cause cracks.

    4. The putty construction is too thick, the internal drying is slow, and the surface drying speed is fast, which is easy to cause cracking.

    1. If there is a large area of cracks, chisel the wall foundation at the crack into a "U" shape, and the spacing of the "U" grooves is greater than 20cm, chisel the chiseled base, and then hang the wire net.

    2. After the wall substrate is cleaned, paste a layer of muslin, kraft paper or newspaper on the wall first, and use the tension of the fiber to ensure the integrity of the latex paint film. This method is relatively simple and easy to implement, but the results are mediocre.

    3. Remove the insulation board on the surface of the wall, or remove the cement wall, install a layer of gypsum board or "five-point board" outside the insulation layer, and then apply latex paint on it. This method removes all the irregular cracks. Cracks are usually at the joints between the plates and are easier to deal with.

    However, this method is expensive and difficult to build.

    4.Use elastic upholstery materials. At present, there is a kind of "elastic putty" that can compensate for wall cracks to a certain extent.

    A certain amount of wall paint can also play a role in covering up small cracks in the wall. However, the "elasticity" of these materials themselves is small and will not work on walls with severe cracks.

    5. Some consumers simply remove the insulation layer of the wall. Although this method can be done once and for all, it will reduce the thermal insulation performance of the wall, so it is not recommended.

    The first step is to choose a qualified putty.

    The second step is to understand the ratio of putty to water and stir well.

    The third step is to clean the wall and repair the missing corners or cracks with plaster in advance.

    The fourth part, the official start of scraping putty. Under normal circumstances, you need to scrape 3 times, but next time you must wait until the last time there is a certain degree of dryness.

    The fifth step is the maintenance work of scraping putty. This is mainly needed when the weather is cold.

    The sixth step is grinding and polishing.

    1.The putty did not dry last time, and it hangs next time. Wet and dry changes can create cracks.

    2.Temperature changes and thermal expansion and contraction lead to temperature cracks.

    3.Structural cracks caused by poor treatment of the base layer or deformation of the wall structure due to static charge.

    4. Poor product quality will causeThe house is scraped with putty and the walls are crackedseams, mainly the material is not in the right proportions.

    5. The frankincense layer batch is too thick.

    In the case of cracks in the color of the wall paint, the effect of partial repair is often not very good, because the color of the wall paint will be a significant color difference once it is painted.
