How can we solve the problem caused by cracking latex paint? What are some things to look out for?

Latex paint has become one of the commonly used uses at home, but often things have certain drawbacks. Latex paint is not used well, or the quality is not good, which will cause the latex paint to crack, but the latex paint is broken, what do we need to do? How to repair the cracks of latex paint?

What am I going to do? The use of construction methods and materials does not lead to rupture. Improper construction of joints at the junction of the old and new walls and ceilings will cause cracks, and cracks will also occur if the construction materials are not used properly.

For example, due to the wrong ratio of cement mortar, the cement layer starts to scrape putty before it dries, etc., the latex paint will break.

If the putty is applied too thickly, the moisture in the wall will continue to evaporate over time, and the wall in the latex paint will also cause large-scale cracking, which will further affect the cracking of the wall latex paint. Cracks appear on the latex paint wall, the bottom layer may not be painted during wall decoration, the paint is unevenly applied, the paint part may not be polished, and cracks appear on the latex paint wall after sanding. First, when the old and new walls of our house are handed over, due to the embedded steel bars and the new and old walls are not directly hung with nets, cracks will appear in the old and new walls in the later stage, and the surface of our walls will also crack together.

In addition to the quality of the paint and the influence of the primer, there are several factors that can cause cracks on the painted surface. Generally speaking, the paint we buy needs to be diluted before being applied. Different products have different formulation requirements and cannot be operated by themselves.

Walls are prone to cracks. Generally, latex paint must be painted about 3 times, but after each coating, it must be dried naturally. This process generally takes about six hours.

In this way, when applied again, the two layers of paint are well bonded and will not break easily in the future.

To put it simply, the drapery is the trace of the paint on the wall that flows down like water droplets. This can affect the aesthetics of the wall. Latex paint has become one of the most widely used wall decoration materials, with the advantages of easy coating, fast drying, waterproof and scrubbing resistance, discoloration and so on.

Depending on the environment and technology used, some people have cracks or arches in latex paint. When the developer delivers the room, some of the walls and ceilings will be scraped white. This generally uses white cement and reinforcing coatings, but these two materials have high hardness and low hardness of putty powder, and it is also difficult to combine the two with putty powder, and the white parts of the original walls and ceilings need to be wiped off.

1. After the wall substrate is cleaned, a layer of good cloth, kraft paper or newspaper is pasted on the wall, and the tension of the fiber is used to ensure the integrity of the latex paint film. This method is relatively simple and easy, but the results are modest.

2. Remove the insulation board on the surface of the wall, or remove the cement wall, install a layer of gypsum board or "five-centimeter board" outside the insulation layer, and then make latex paint on it. This method can remove all the irregular cracks, and the cracks are generally the joints between the plates, which are easier to deal with. However, this method is expensive and difficult to construct.

3. Adopt decorative materials with elasticity. At present, in the treatment of wall substrate, there is a kind of "elastic putty" that can make up for the problem of wall cracks to a certain extent. The "three-in-one" of Nippon paint can also play a role in covering small cracks in the wall.

However, these materials themselves are less "elastic" and do not work on walls with strong cracks.

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

After the wall substrate is cleaned, some cloth or kraft paper and newspaper can be pasted on the wall, and the tension of the fiber can be used to ensure the firm use of latex paint, which is the simplest and most effective; It is best to choose some elastic decorative materials after using latex paint, because this can make up for some small cracks on the wall, which is of great help to solve the cracks of latex paint.

At this time, it can be covered with a mesh cloth and then repaired with plaster and cement. Be sure to get to the root of the problem, be targeted, and also choose high-quality materials for repair.

Latex paint wall cracking treatment - the cause of wall cracking.

Latex paint wall is also commonly called paint wall, this kind of wall is smoother than putty powder wall, but the moisture-proof and alkali resistance is poor, the hardness is not enough, and it is easy to crack. There are two main types of wall cracking, namely settlement cracking and cracking. 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.

Latex paint wall cracking treatment - correct treatment and prevention methods.

For the latex paint wall that has cracked, it needs to be treated in the following way: consumers need to have the understanding that the wall is cracked, no matter what is brushed, the crack will not disappear.

For the wall cracks are large and obvious, which indicates that the putty layer has been loose and unstable, and the surface latex paint will crack and fall off, it is recommended to remove the latex paint and putty layer, and re-batch the putty. For some cracks on the surface, but not too serious, you can brush putty and latex paint for the cracks, and repair the brush locally, so as not to affect the overall effect, you can also paint the Jialifeng wall base film, and if the conditions are good, you can paste wallpaper to cover the cracks on the surface.

Wall paint cracking is a lot of new homes for owners, and after a period of renovation or even a very short period of time, you will find more or less cracking on the river surface. The cracking of the paint film on the surface of the wall will seriously affect the visual effect of the decoration of the wall. It can even cause the paint film to crack, which will affect the life of the wall.

If only the crack of the surface. Just use fine sandpaper to sand off the cracks, and choose the same color of the wall area to repaint.

This needs to be checked and analyzed in many aspects, if it is a crack in the base layer, it is necessary to see whether it is accompanied by hollow drums, the size of the area, if the area is large, the place should be chiseled off, and smeared with cement mortar in several layers, after drying, paste fiberglass cloth or high-elastic fiber paper tape in the place, the area should be larger than the chiseled area, and then scrape the putty and paint it. If it's just surface cracking, just shovel off the putty, stick fiberglass cloth or high-elastic fiber paper tape, then scrape the putty and paint it. Chenguang nano silver high-efficiency antibacterial interior wall latex paint is healthy and environmentally friendly, dirt-resistant and weather-resistant, and of excellent quality.

In the repair process, it is necessary to wait for each paint to dry thoroughly before the next paint, so as to ensure that the latex paint will not fall off in the later stage.

Latex paint has become one of the common uses of home decoration, but often things will have certain drawbacks. Poor use or poor quality of latex paint will lead to cracking of latex paint, but what do we need to do about cracking of latex paint? How to repair latex paint cracks?

What do we need to do about it? Check it out!

1. Causes of cracking of latex paint.

1.Cracks in the wall are caused by uneven foundation settlement and excessive temperature changes.

2.The junction between the new wall and the old wall, the joint between the brick wall and the ceiling, and the slotted construction of the wall, if the material or construction method is not right, it is easy to crack in the future.

3.It may be that when the wall is decorating, the putty powder is not scraped evenly enough and is too thick, which will also lead to cracking of the latex paint or the phenomenon of the latex paint falling off the wall.

4.The quality of construction materials is not high, such as: cement grade is too high, cement is expired, sand is too fine or mud content is too high, the proportion of cement mortar is wrong, and the cement layer is not dry and scrapes putty, etc., which will crack in the future.

5.If the base layer is not cleaned or the putty quality is problematic, it will also cause cracking of latex paint.

6.Defective paint quality can also cause cracking of latex paint.

Second, how to repair the cracks of latex paint.

1.First of all, clarify the cause of the cracking of the latex paint, and then decide how to repair it.

2.If the cracking is small, we can repair putty and latex paint for the cracked parts, without affecting the overall effect; If the crack is large, you can paste the mesh cloth and then apply putty latex paint; If there is obvious cracking and peeling, it is recommended to remove the latex paint and putty layer and redo it.

3.If the cracked area is large, we can choose to rebuild, which will help us create a better living environment.

3. How to prevent cracks on latex paint walls.

1.First of all, choose high-quality latex paint when decorating, and high-quality latex paint is a prerequisite for ensuring quality.

2.Secondly, we should pay attention to the quality of construction in construction, do not cut corners, and must pay attention to the details in construction.

3.The work of the base wall must be in place, so as to better ensure that such problems will not occur.

That's all there is to know about what to do if latex paint cracks, and I hope these contents can solve the problems you encounter. For the solution of latex paint cracking, we must first clarify the cause of cracking and then draw conclusions, whether it is not possible, we can ask professional workers to repair.

I think in this case, you can clean the wall base, put a layer of kraft paper on the wall to use the tension of the fiber to ensure the integrity of the latex paint film, and you can remove the insulation board on the wall, and then install a layer of gypsum board on the outside of the insulation layer, and then make latex paint on it.

Remove the insulation board on the surface of the wall, remove the cement wall, install a layer of gypsum board or 5 centimeter board outside the insulation layer, and then paste a layer of good cloth, kraft paper or newspaper on it to ensure the integrity of the latex paint film by using the tension of the fiber; This is one of the best ways to solve the problems caused by latex paint.

Cracks appear on the latex paint wall, maybe the wall is decorated, the bottom paint is not brushed, or the paint is uneven, and there may not be brushed to the part of the paint, after the fine decoration, the latex paint wall cracks. The first is that when we have the handover of the old and new walls in our home, we do not do the reinforcement implantation and the new and old walls are not directly hung with the net, so that the new and old walls will have cracks in the later stage, and then our wall surface will also crack together.

Nowadays, latex paint has become one of the most widely used wall decoration materials, which has the advantages of easy brushing, rapid drying, waterproof and scrubbing resistance of paint film, and changeable colors. Due to the different environments and processes used, some people encounter cracks or even arches in latex paint, when the developer delivers the house, some walls and top surfaces will be scraped white, which is generally used white cement or tempered coating, the hardness of these two materials is relatively large, and the hardness of putty powder is low, both are difficult to combine with putty powder, so the original wall, the top surface of the white is needed to be shoveled, <>

The first is the cracking of the latex paint due to the cracking of the wall surface of the underground base. If the crack is relatively large, there may be some safety hazards. This needs to be dealt with by contacting a professional, after all, it is up to a professional to have such a problem in the place where you live.

If the crack is very deep like the one in the picture, it is generally caused by the settlement of the wall itself, as long as the wall continues to settle, even if it is repaired at the time, it will soon crack again. The quality of latex paint is still very different, although it is difficult to distinguish from the appearance and smell, but when it is applied to the wall after a period of time, the difference can be found. The content of inferior latex paint is unreasonable or some components are missing or replaced by other ingredients, <>

If you use ** latex paint with high purity, the life of the product is 3 to 5 years. Some people's walls have a long shelf life, on the one hand, the construction master has enough materials and good construction technology; On the other hand, it is mixed with other materials, which makes the wall hardness increase and difficult to deform.

There may be the following reasons, dry weather, ventilation caused by open windows, structural cracks in the wall itself caused by the frame structure of the house, and the putty powder is not dry at the time of wall alignment, and the construction personnel begin to paint latex paint and cause cracking, which is completely artificial, and the main reason is that the construction personnel are not very skilled.

At present, in many new houses, there are new types of insulation walls with insulation layers. This kind of wall is easy to crack the latex paint in the decoration. In fact, this kind of cracking is caused by cracks in the cement of the wall, or cracks in the joints of the "insulation board" of the wall, which is not a quality problem of decoration, but an insurmountable defect in the construction.
