Master Liu, a decorator, said that the wall generally cracks in a short time after it is just done, and there are several reasons for it, and it is recommended that the owner compare it.

One is that the wall base material is of poor quality and low strength. The main thing is putty, if you use poor quality putty powder, the general water resistance is relatively poor, the paint is liquid, the main ingredient is also water, the putty that is not resistant to water will appear pulverized after encountering the paint, which may lead to hollowing, and then cause cracking.

Master Liu said that this kind of cracking is more common, and the cracking is generally accompanied by hollowing, and the wall skin can be knocked off one by one along both sides of the crack. To remedy, it is recommended to shovel it off, and then pick a water-resistant putty with *** point to redo it.

The second case is that the putty batch scraping is too thick, and it dries and shrinks. Generally, the material of the wall base layer, if the batch scraping is too thick and lacks maintenance, it is prone to cracking. For example, cement, many home decoration use cement to pursue quick drying, which is actually not very scientific, because the process of cement gradually firming (that is, increasing strength) is a process that requires a relatively long time to retain water, and if it dries too quickly, it is easy to depowder, cracking and other phenomena.

Similarly, if the putty is too thick in a single batch, uneven drying will also occur, which will cause cracking. This kind of cracking generally appears in the corner of the wall or in a place where the wall is not flat (easy to thicken), the crack is wide in the middle and narrow at both ends. If it is controlled within 2 mm each time, it is no problem to scrape multiple times.

To solve the cracks of the wall in this situation, you only need to polish it locally, and then repair it with putty.

The third situation is that the crackable parts are not well treated with anti-cracking. Generally, you will encounter internal insulation walls, sand-and-gray walls of old houses, light walls (including new construction), poor quality of base materials such as cement or gypsum, the junction of two walls, slotting left by hydropower renovation, and crackable parts around construction holes.

There are two kinds of anti-cracking treatment of the cracking part, such as the poor quality of the internal insulation wall and the base materials such as cement or gypsum, etc., which are suitable for the whole wall, and the slotting and cracks around the construction hole left by the hydropower transformation are suitable for doing the local. The treatment method is generally to apply cloth or kraft paper. If there is no anti-crack treatment, it is recommended to shovel it off, do anti-crack treatment first, and then scrape putty and paint.

The steps for repairing cracks in latex paint walls are as follows;

1. Clean the wall, clean up the loose or stained places, and then use cement mortar to make up for it, and remove the excess residue.

2. Repair the wall, use water plaster to level the wall bumps and uneven places, treat it with sandpaper after drying, and finally clean up the floating dust.

3. Scrape putty, usually do it three times, such as kitchens, toilets, bathrooms need to take polyvinyl acetate than cement than water is equal to 1 to 5 to 1 ratio, the first time with a rubber scraper to scrape horizontally, and then use a scraper to deal with, pay attention to the joint to be careful, and finally scrape once to deal with the end.

4. The first time the latex paint sequence is first up and then down, after the wall is cleaned, take the cloth to sweep away the dust, and then the latex paint is brushed with a row pen, and the floating and loose hair on the pen should be cleaned up, and the latex paint should be stirred and balanced before use, so as to avoid the situation that the brush can not be opened, and then fill it with putty after drying, and then polish it with sandpaper, and finally clean it up.

5. Brush the latex paint for the second time, stir the putty before using it to balance it, so as to avoid penetrating the top, and after the paint film is dry, take the sandpaper to polish it flat, and finally remove the dust.

6. Brush the third latex paint, the practice is the same as the second time, but because the latex paint film dries quickly, it needs to be operated quickly, and the order of painting is from one end to the other.

Cracked pulp nonwoven mesh fabric pvc, then whitening repair paint.

2. Structural cracks, the specific reasons are: the expansion joint between the structural wall and the brick wall extends to the surface of the wall, and the cracks will also be indicated by the cracks formed by latex paint, in the case of such cracks, professional construction personnel should look for appropriate measures according to the actual situation, solutions: this type of crack is complex and difficult to repair, usually, during maintenance, the base layer must be completely removed, the cracks must be cleaned, and then filled into the space with epoxy resin until the space is filled, Attach the carbon fiber ripstop fabric to the surface of the hole, and after all of this, you can repair the putty to make latex paint.

1. The placement of the house is mainly due to the inequality of the foundation, which is very common in multi-storey old houses, specifically, the surface of the wall presents cracks in the direction of 45°.

When decorating the wall, in order to make the wall more high-grade and more beautiful, many people will consider painting the wall, but after a long time, the paint surface may crack, so what is the reason for the cracking of the paint? How do you repair a crack after it has been cracked? Today, I will explain to you the specific repair method.

1. How to repair cracks in the painted wall.

First of all, use a shovel to remove all the putty layer and paint on the cracked wall; secondly, clean the dust on the wall; Then the cracked place of the wall is repaired and leveled with cement mortar, and after the cement mortar is completely dry, it is also necessary to hang the net with hand dust or paste the nylon mesh cloth with relatively high strength; Finally, the wall is scraped with putty and latex paint.

Second, the reasons for the cracking of the painted wall are good potatoes and oranges.

1. The foundation of the house has subsided, resulting in cracking in the structural layer of the house.

2. The quality of the cement mortar used by the developer when building the house is relatively poor, and the joints of the wall are cracked.

3. The quality of the putty used in decorating the house is relatively poor, and the construction process is not in place, resulting in the cracking of the putty layer.

4. The wall paint used is not up to standard, or the thickness of the wall paint is uneven during the construction, and there is no patient polishing, resulting in cracking of the wall paint.

3. How to prevent wall cracking.

First of all, you must choose a good quality putty; The second is that the putty layer should not be too thick when scraping putty, and try to keep it within 5 mm; In addition, before painting putty, if you find that there are cracks on the wall, it is best to do a good job of anti-cracking treatment.

Fourth, is it easy to crack when painting wall paint in winter?

Painting the wall in winter, especially if it is prone to cracking, mainly because the climate in winter is relatively cold, but if the floor heating is installed at home, then the floor heating can be turned on, and the construction will be carried out when the temperature at home reaches minus 5 degrees, so that the probability of cracking the wall is very small.

Tips: Before painting the wall, be sure to level the wall, the leveling material can choose to use putty powder, if the wall is not leveled, then the wall will not only crack, but also bulge.

1. If the crack is relatively small, the treatment method is relatively simple. Use a knife to cut the crack directly, then use coarse sandpaper to polish the crack again, and after the polishing is done, you can paste the caulking with white glue, then level it with putty, and then brush the latex paint. 2. If there is local cracking, the cracked part should be removed first, and then the anti-cracking putty should be brushed, and the latex paint can be brushed again after polishing, so as to ensure sufficient flatness.

3. Once the latex paint wall falls off in a large area, the wall plastering must be completely removed, scrape a layer of gypsum board or put it on the wall, and then apply a layer of latex paint. The reasons for this problem: 1. The wall may be unclean, with dirt, water or other pollutants.

2. The surface of the wall primer may be too smooth, and the bottom polishing is not enough to stool or there is no polishing at all. 3. The primer and the topcoat may not match or have poor compatibility, the primer is made of nitro, although the nitro paint is not completely dry, but the primer containing a relatively stronger solvent is used, resulting in no obvious undercut or even cracking of the topcoat. 4. It may cause cracking due to the different linear expansion coefficient of the surface layer when it is affected by the effect of wood machinery.

5. It may be that the bottom layer of cement is not completely dry, and the lime is too alkaline. 6. It may be that the construction environment is too bad, the temperature is too low, the temperature difference is large, the humidity is large, and the paint film expands and contracts under the action of cold and heat, resulting in cracks.

Cracks in the walls of new homes are a more common problem in decoration. There are many reasons for this, it could be that the wall is too thin, the cement of the wall may not be dry before bonding, it may be an original problem with the structure of the building, or it may be too hot in the house upstairs, etc., thenHow to repair cracks in wall paint

Treatment: If the crack has penetrated the putty layer, first use a sharp tool to expand the crack to the size of a screwdriver, fill the caulking plaster and polish it, and then level it with an online bucket or brown paper and combine it with the putty. Finally, follow the normal process.
