There are cracks in the wall paint, can I repair them?

For self-built houses, due to the different forces of each part of the house, the foundation will have a self-balancing process, in this process, it will produce tension on the local wall, causing cracking of the wall, which will lead to cracks in the latex paint, which is manifested in irregular oblique joints on the surface of the latex paint. The relevant departments can pass the acceptance, and there are no excessive quality requirements. And the developer uses ordinary putty, the wall is basically not brushed with the bottom coating, when the owner gets the key to fine decoration, the putty on the wall is shoveled clean, and then it can be finely decorated.

Then do the cement plastering, wait until it is completely dry, re-hang the fiber mesh and scrape the putty, and finally paint it. What we need to pay attention to when scraping putty is to scrape it evenly, and the size of each pass should not exceed two millimeters, so that it is not easy to crack in the later stage. It has the advantages of easy brushing, fast drying, waterproof and scrub-resistant paint film, and variable color.

Due to the different environments and processes used, some people have encountered cracks or even arches in latex paint, so let's analyze the causes and solutions.

First use a shovel blade to shovel the paint and base putty on both sides of the cracks, shovel clean, then use the anti-crack treasure to smooth the cracks, and then use white latex to paste the anti-crack net, and so on, and then scrape the putty twice, the putty is dry and polished and smooth, and finally painted!! 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, if you do not shovel off the putty, there will definitely be cracking and falling off in the later stage.

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. If it is the last one, then it is caused by the lack of time gap in the last batch of cement mortar. If there is no problem with the quality of the subbase, then the surface treatment is relatively simple.

If the bottom layer is not handled well, then you have to shovel it and start from scratch, remember that I didn't lie to you, it's true, and the heart is good for you.

At this time, you can go to repair yourself, in this case, the first thing is to buy some paint, and you must pay attention to the technique in this process, most people often do not go to remedy, you can go to the corresponding professionals.

You can't make up for it yourself, you can go to a professional repair master, so that there is no trace of it.

You can fix it ourselves, and we can paint the wall so that it can be restored to its original appearance, and it will be very beautiful.

It can be repaired, but it needs to be scraped off all the periphery of the crack, and then wet with water and then apply putty, and only after drying can you use new paint, not directly applied, otherwise the paint will easily fall off.

1. You can use a shovel to remove all the putty layer and paint on the cracked wall, and then clean up the dust on the wall. 2. Then repair and smooth the cracked place of the wall with cement mortar, and after the cement mortar is completely dry, it is also necessary to hang a net or paste a nylon mesh cloth with relatively high strength. 3. Finally, scrape putty and paint latex paint on the wall.

1. First of all, you must choose putty with good quality; The second is that when scraping putty, the putty layer should not be too thick, and try to keep it within 5 mm; Another thing to say is that 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.

2. Painting the wall in winter, especially 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 temperature at home reaches minus 5 degrees before construction, so that the probability of cracking on the wall is very small.

3. Before painting the wall, you must first level the wall, and 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.

4. The wall paint used is not up to standard, or the thickness of the wall paint is uneven when the workers are constructing, and they are not patiently polished, resulting in cracking of the wall paint.

First of all, use a shovel to remove all the putty layer and paint on the cracked wall, then clean up the dust on the wall, and then repair and smooth the cracked place of the wall with cement mortar. The reasons for this problem: 1. The foundation of the house has sunk, resulting in the cracking of 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 cracks appear at the joints of the wall. 3. The putty used in decorating the house is of poor quality, and the construction process is not in place, which leads to 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.

5. First of all, we must choose putty with good quality; 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. 6. Painting the wall in winter, especially if it is prone to cracking, mainly because the climate is relatively cold in winter, 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 on the wall is very small.

First of all, determine the causes of cracking, according to the characteristics of the house and the construction method, the current causes of cracking of residential houses are as follows:

1) Expansion joints between the structural wall and the brick wall.

This crack will extend to the surface of the wall, causing cracks to form in the latex paint on the surface of the wall. During repairs, the base layer needs to be removed, the cracks are cleaned out, and then the gaps are filled with epoxy injection until the gaps are filled. Paste a carbon fiber anti-crack cloth on the surface of the gap for reinforcement, and after all this is completed, you can scrape the putty for latex paint repair.

This type of cracking is the most difficult to repair and the most complex to repair.

2) Cracking of the cement stucco layer.

This kind of cracking is often the ratio of cement and yellow sand when the wall should be powdered, many hydraulic enterprises reduce the amount of cement, and the result is the cracking of the cement mortar stucco layer, and lead to the cracking of the latex paint.

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

3) Cracking of the putty layer.

This crack is the slightest crack and is often caused by the putty layer being too thick or too thin. When repairing, you can directly paste it with a bandage made of anti-cracking fiberglass mesh or log pulp, and then scrape the putty in batches.

If it is a crack in the paint caused by cracking of the wall, then ......
