Latex paint cracks in houses, how to solve this problem?

Foundation settlement For self-built houses, the foundation will have a self-balancing process due to the different forces of the various parts of the house. In this process, tension will be generated on the local wall, which will cause the wall to crack, resulting in cracks in the latex paint, which is manifested as irregular diagonal joints on the surface of the latex paint. Any latex paint has a strict mixing ratio.

When preparing latex paint, some masters do not mix it according to the requirements and add more water to dilute it, resulting in the surface of the latex paint can not form a good film, or the film is too weak. If it takes a little longer, there will be a slight cracking.

After the latex paint is applied, it should be dried in a cool place for about 3 to 4 days. During this period, doors and windows should be closed to maintain indoor humidity and prevent latex paint water from rapidly volatilizing due to air circulation, resulting in cracks on the surface of latex paint. It is manifested as a dry crack that will fall off when touched by hand.

The main body of the building is not as stable as expected. It sinks and even tilts. The wall can be tilted to one side or both high and low.

Buildings are allowed to undergo a certain degree of deformation, but in the process of deformation, it can cause cracks in the walls.

The cracks caused by the main problem are generally deep, even in the lowest cement layers. This problem is also the most difficult to solve. In addition to shoveling off the surface of latex paint and putty, cement walls should also be repaired.

In general, this problem cannot be solved without redecorating. This crack will extend to the wall, causing cracks in the latex paint on the wall. When curing, the base layer should be thoroughly removed, the cracks should be removed, and then epoxy resin should be injected into the gaps and filled until the gaps are filled.

Paste carbon fiber rip-proof cloth on the surface of the gap to reinforce. When all this is done, you can repair the latex paint with putty.

This crack is the most difficult and complex crack to repair. This crack is usually caused by the wrong ratio of cement and yellow sand when using a powder wall. Many water conservancy enterprises reduce the amount of cement, resulting in cracking of the cement mortar coating layer and cracking of latex paint.

To repair such cracks, simply remove the putty layer to expose the cracks in the cement paint layer, and then apply them directly with a carbon fiber anti-crack cloth. This crack is the slightest crack and is usually caused by the putty layer being too thick or too thin. For repair, apply a bandage made of crack-resistant fiberglass mesh or raw wood pulp directly and then apply putty.

If there are cracks in the latex paint of the house, you can buy some latex paint to repair it and cover the cracks, or choose some latex paint of better quality, which is not easy to crack.

Remake the cracked latex paint product into wall putty latex paint, if the latex paint crack is very small, you can hang it on the wall to decorate the crack.

The putty of the house is not completely removed, and the developer will choose a relatively hard white cement and tempered paint, also because there have been small hunters on the water surface of the wall, but they have not been treated in time, which makes the wall crack.

It may be because the material used is relatively inferior, and the original putty is not removed when scraping, the wall is not flat, and the hardness of the material used is relatively large, and the toughness is relatively low.

It may be because the original putty has not been shoveled off, resulting in it not being combined with the wall joints, or it may be because the cement blocks on the wall have cracks and have not been treated in time.

If the latex paint cracks on the wall are deep, most of the cracks are due to the settlement of the wall itself. If the walls are still sinking, cracks will appear even if they are repaired in time. Its presence not only affects beauty, but also makes the home dangerous.

If the wall is only partially cracked or cracked, you can wait until the spring is not heated, scrape off the latex paint around the crack with a shovel, and then apply putty and latex paint. But only surface cracks do not need to be so complex.

Just sand it with sandpaper and apply latex paint of the same color. Regardless of improper operation or quality problems, the putty layer will be pulverized or even cracked. Resilient finishes should be done before house renovation, which can greatly reduce the problem of cracking.

Even small cracks in the wall can be used without any problems.

The putty should be evenly whitished on the wall, not more than 2mm each time, otherwise it will be easy to crack in the later stage. If there are cracks in the wall from bottom to top, it is because the plastered base layer is not connected to the net, but this is not a big deal. This problem can be solved by getting a piece of paper directly.

I think it may be due to the poor quality of latex paint when purchasing, and the cracking will occur after a long period of aging in the house, and if it is some southern areas, cracks will also occur due to moisture for a long time.

Be. Latex paint cracks in the house are because the house has been wet for a long time, and the latex paint has not been completely cured, which is easy to cause cracks.

Settlement cracks are mainly caused by the subsidence of the wall structure, and the cracks are mainly caused by the insufficient strength of mortar or putty, and there are mainly the following reasons for wall cracking:

The first is that there are cracks in the insulation layer of the original house, which leads to cracks in the wall after decoration;

The second is that the wall is repaired and painted improperly after slotting, resulting in cracks in the wall shrinkage;

The third is that the ratio of cement is not accurate when plastering, and it is easy to crack if the ratio is high;

The fourth situation is that the ratio of wall putty is improper or uneven scraping.

The fifth is that the ratio of latex paint and water is not suitable, and the above non-standard operations will lead to cracking of the wall.
