What should I do if the latex paint used on the walls of my home is cracked now?

The walls of the home are all made of latex paint, which is a simple decoration style, but there will definitely be cracks in the later stage. If the cracking is a congenital cause, you can use the paint product on the wall to create it. Generally, the decoration should choose the quality of the pass, but if the pass or improper operation, there is no way to achieve the film through the temperature level, and it is not easy to cause solidification, which will lead to cracking.

Of course, this method is also more troublesome, you need to sandpaper it, and then choose the same color to repaint. <>

I believe that the owners who have renovated will have this phenomenon, basically irregular cracks are also common, the surface of the wall can be removed, and then the cement wall can be missed, and the same latex paint can be selected. However, the cost of this method is also relatively high, and the difficulty of construction is also very large. Generally, the family needs to repair, usually more troublesome, if you have the conditions or relevant technology, you can repair it at home is the best.

Don't worry too much about cracks, because they can happen later. <>

In particular, some people are blind when decorating, and they do not compare when choosing materials. Like elastic putty, it may be relatively unfamiliar to everyone. Generally, elastic decoration materials are used in decoration, so that the bottom layer of the wall is better handled, and there will be few problems like wall cracks in general.

Therefore, we should compare and understand more about decoration, and choose better products. If you don't understand, you can also go to your friends or a professional decoration company for comparison. <>

In the case of serious cracks, we must pay attention to it. It is possible that the structure of the wall itself has cracked, resulting in slight cracks on the surface of the latex paint. If there are cracks in the wall, appropriate treatment measures should be taken in the later decoration.

In particular, if there is a crack in the original wall decoration, it must be filled in the later stage, otherwise there will be a sinking drop or a change in temperature, and there will be cracks. If necessary, it is necessary to find a professional building structure personnel to test according to the actual situation, which can also play a corresponding measure.

Point 1: If a crack appears, it should be repaired immediately, point 2 can be repaired with a special repair, and point 3 can be reapplied with latex paint.

First of all, remove the putty layer of the wall, then until you see the cracks in the brush layer, then use carbon fiber anti-crack cloth to paste, and finally repair it with latex paint.

If all the latex paint used on the walls of the home is cracked now, if the cracks are relatively small, then hold on for a few more years, if the cracks are relatively large and cannot be adhered to, then only another layer of wallpaper can be pasted on the wall.

In life, cracking of wall latex paint occurs from time to time. This is unsightly, and may also cause water leakage and water seepage. If there are cracks in the surface of the latex paint, it must be repaired, but many friends are at a loss in the face of such a situation.

The solution to the cracking of the wall latex paint.

1.Expansion joints between structural and brick walls.

This crack is caused by improper construction in the early stage. This crack can extend to the wall, causing cracks to form in the wall latex paint. When repairing, the base layer must be completely removed, the cracks must be removed, and then epoxy resin must be injected into the cracks until the cracks are filled.

Paste carbon fiber anti-crack cloth on the surface of the gap for reinforcement. After all this is done, you can use batch scraping putty to make up the latex paint. This crack is the most difficult to repair and the most complex.

2.Cracking of the cement plastering layer.

It is convenient to repair such cracks. This cracking is often caused by the wrong ratio of cement to yellow sand when the wall is pulverized. Many hydraulic engineering enterprises reduce the amount of cement, resulting in cracking of cement mortar stucco layer and cracking of latex paint.

To repair this crack, simply remove the putty layer to expose the crack in the cement plastering layer, and then directly paste it with a carbon fiber anti-crack cloth.

3.Large chunks fall off.

Solving this situation is not so simple. Once the latex paint wall comes off, neither of the above methods can be treated. The walls need to be thoroughly scraped and plastered, then scraped or covered with a layer of plasterboard, followed by a new layer of latex paint.

This is a great way to deal with latex paint peeling off.

How to prevent latex paint wall cracking?

1) Pay special attention to the quality when buying latex paint. The cracks in the wall surface of latex paint are often related to the quality of the paint itself, so special attention should be paid to the quality when buying latex paint.

2) The treatment of the wall foundation should be carried out with care. When considering the question of "how to make wall cracks with latex paint", the most important thing is to pay attention to the substrate of the wall. In addition to ensuring the cleanliness and tidiness of the base surface, alkali-resistant primers should also be chosen.

By the way, there are requirements for temperature during the construction of latex paint, and generally more than 5 is a suitable construction environment.

Many families have encountered cracked latex paint or moldy walls, which can be solved according to the above methods. In daily life, we must pay attention to the moisture-proof work of the wall, and fundamentally avoid the wall from becoming moldy due to moisture, which will be convenient to use and reduce the trouble and waste of money caused by wall treatment.

You should buy some restoratives, or you can go to a professional store to buy them, these restoratives will not crack when applied to the wall.

At this time, it should be repaired in time, and then the putty should be scraped again in the cracked place, and then repainted, and then the window should not be opened immediately for ventilation after repair.

Wait for the wall to dry and paint again, after the painting should be ventilated, when brushing should be a little more, to cover the previous cracks.

In this case, you should buy the appropriate latex to fill these cracks, or ask the appropriate professional to help with the repair, after all, such behavior will cause an overall aesthetic problem.

In such a situation, I think it is necessary to choose a good quality latex paint and repaint it again.

First of all, you can remove the latex paint, reapply other paints, or paste some wallpaper or hang some decorations on the wall, which can be covered.

1. Improper wall construction.

In the process of wall construction, the construction of new walls, old walls, wall slotting and other positions, without anti-cracking treatment or non-standard anti-cracking treatment, is one of the important reasons for the appearance of cracks on the wall.

2. Improper use of cement.

When the wall is batched with putty, the cement grade selected is too high, the ratio of sand and cement is not appropriate, or the cement layer is not dried and the latex paint is brushed, which will also lead to wall cracks.

3. Improper handling at the grassroots level.

Before the wall is filled with new putty, the base layer or putty of the original wall is not cleaned, and the latex paint will be separated from the new putty, which will also lead to cracks on the wall.

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.

It is common for the wall to crack after decoration, but it can actually be avoided.

Small cracks are normal. Because there may be problems with the original building on the wall, if the cracks are too obvious, it is a construction problem, such as the base treatment is not in place. There is also wall paint that is a second-class product. It is recommended to use wall paint, preferably good and elastic.

There are two main reasons for the cracking of the wall after painting: one is that the basic treatment materials of the wall are unqualified, and the other is that the place that needs to be anti-crack treatment is not anti-cracking, or the place where the anti-cracking treatment is not done in accordance with the specifications. Specifically, there are the following reasons:

1. The basic treatment and materials of the foundation treatment are unqualified, such as the poor quality of the mesh cloth used for anti-crack treatment, the selected putty is non-water-resistant putty, and the cement plastering layer of the wall, gypsum putty and other treatment layers are not operated in accordance with the specifications, resulting in the hollowing and delamination of the treatment layer of the wall.

2. The wall is not treated with anti-cracking or the anti-cracking treatment is not standardized, and the places where the wall needs to be anti-cracking mainly include the following:

1) The place where the light wall and the load-bearing wall meet;

2) the place where the light body wall and the light body wall meet;

3) the part of the light body wall that is in contact with the top of the floor slab;

4) Where there are slotted pipelines on the wall;

5) Where there are cracks and cracks in the base of the wall;

6) Where there are construction holes in the wall.

In the process of decoration, the above-mentioned parts are not treated with anti-cracking, which may lead to cracking of the wall in the later stage;

It is a comprehensive technology that includes materials, machinery and tools, and construction. After grouting repair, the inside of the crack is filled with AB-1 grouting resin, and its tensile strength and adhesive strength are high, and no re-cracking will occur. Or the connection between the trunking and the original wall is cracked after the plumber slots, most of which are not the quality problems of the decoration, but the defects of the original wall itself.

If these problems occur, the wall should be professionally reinforced and repaired in time before the next step of construction.

However, this method cannot remove all the irregular cracks. Since the cracks are usually cracks between the plates, it is easier to deal with. However, due to the high cost of this method and the difficulty of construction, it is more troublesome for ordinary people to repair it by themselves.

If the wall crack area of the home is small, the cement cracks and cracks, mostly for the denser and smoother cobweb fine lines, the premise of generally using high-grade cement plastering is thicker, mostly brick-concrete structure, this kind of cracking should be completely dried after the cement is completely covered with a large area of cloth, repainting can be repaired.

But if there are cracks just after the decoration, it means that the decoration company has a problem with the wall treatment, which is to be solved by them. If after a period of time, a slight cracking is normal, but if it is peeling and peeling, it is still a matter of construction quality and material quality. As the saying goes, seven points of putty and three points of paint, good paint also needs good putty.

When choosing putty, you should look at the brand, quality certificate and production date to ensure the best and prevent expiration. It is best to choose putty that matches the paint, and the improper ratio of paint and water will also lead to cracking of the wall.

At the joints between the new wall and the old wall, or where the wall is slotted for construction, it may be due to the wrong material or the later cracking caused by improper construction by the construction personnel. Or cracks in the cement of the wall, which cause cracking of latex paint, are not a problem of decoration quality. Judging from the current construction technology, this problem cannot be completely overcome for the time being.

If you want to solve this problem, you have to start from the actual situation of your own home.

1. First of all, if the cracks on the wall are relatively small, you can use a knife to directly cut the cracks, polish them with coarse sandpaper, paste the caulking with white glue after polishing, then level them with putty, and finally brush the latex paint again. 2. Secondly, if there is only local cracking, you should first remove the cracked part when dealing with the cracks on the latex paint wall, and then paint the putty with crack resistance, then polish it, and then confirm the flatness, and then you can brush the latex paint again. 3. Finally, if the cracks on the latex paint wall appear to fall off in large areas, then the above-mentioned method of treating the cracks on the latex paint wall will not work.

However, you can only remove the wall skin directly, re-plaster, and then make a layer of gypsum board or scrape it on it, and then apply latex paint.

Hello answer, I have seen your question and am sorting out the answer for you, please wait a moment 1If the wall latex paint cracks are deep, most of them are because of the problem of settlement of the wall itself, if the wall is still in the process of sinking, even if it is repaired in time, there will be cracks, its existence will not only affect the appearance, but also make the home dangerous.

If there are only local cracks or cracks on the wall, then you can wait until the spring when there is no heating, use a shovel to scrape off the latex paint around the cracks, and then apply putty and latex paint. But just the surface cracks don't need to be so complicated, just sandpaper it and then apply the same color latex paint.

After the latex paint has cracks, you can find a professional repair team to repair it, but this crack cannot be completely repaired. If it's really serious, it will have to be renovated.

Solution: First of all, we must shovel off the paint and the underlying material, and the fine line cracks should be opened V grooves or digging points, filled with gypsum caulking powder, glued to kraft paper or cloth tape after drying, and then scraped putty from the new batch, polished and painted.

You should buy some wallpaper and stick these walls with wallpaper, so that the wallpaper can cover the cracks on the walls.

First, if there is a crack, it may be that the quality of latex paint is not very good, you can find a latex paint store to discuss and remedy. Second, you can find professional wall repair personnel, and your own blind work may become more and more serious.
