What should I do if there are cracks on the wall just after painting latex paint?

Cracks appear on the wall of the freshly painted latex paint, the main reason is that he dries too fast in the process of brushing latex paint, causing this phenomenon, we can use sandpaper to beat this crack at this time, and then use some of these anti-crack products, and then repaint it.

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.

For wall cracks with a depth of more than 1 cm, we need to preferentially use cement mortar to repair the cracks in the wall, and then apply wall paint.

1. When cracks are found in the wall of the home, they should be repaired as soon as possible. The first step is to remove the cracked wall, we first sprinkle water on the wall, wet the wall and then shovel, so that the shovel is more labor-saving. The wall skin should be removed to expose the cement mortar wall or putty layer.

2. After removing the old wall skin, the next step is to apply the interface agent on the wall, and we must pay attention to the uniform application. For the cracks, special treatment should be carried out, and the cracks can be pasted with kraft paper tape and white latex to prevent further cracking. In addition, it is necessary to level the uneven wall, generally plaster is more commonly used, and the uneven difference is not more than 0 5 cm, and then the cloth:

Generally, non-load-bearing walls such as lightweight walls and insulation walls need to be patched.

3. After these are processed, it is time to prepare to scrape putty. The quality of putty is related to the effect of construction, it is better to choose putty with higher particle fineness and harder texture, and you can also add a certain amount of white latex to improve the hardness of putty. After the putty is dry, it also needs to be sanded on the wall.

After sanding, the wall must be thoroughly cleaned to avoid too much dust and affect the adhesion of the paint.

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.

When decorating a new house, will the ventilation wall crack after brushing latex paint?

There are many reasons for cracks in the wall, such as structural cracking of the original wall, bulging cracking of the wall after being wet, cracking of the original wall base layer in place, and cracking between the new wall and the original wall. If the gap is too large, you can first paste kraft paper, and then use a good cloth to lay the base, brush the interface agent, and then scrape the putty or waterproof putty twice, polish and paint it, and you can also choose to paste wallpaper to cover the effect better. If you have any questions, you can consult the lightning refresh.

There are five conditions that can cause the wall to crack.

1. There are cracks in the insulation layer of the original house, which leads to cracking of the wall after decoration;

2. Improper repair and painting after wall slotting, resulting in cracks in wall shrinkage;

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

4. The ratio of wall putty is improper or uneven scraping;

5. The ratio of latex paint and water is not suitable;

All of these non-standard operations can lead to cracking of the wall.

If it is a lightweight partition wall, generally use good cloth or kraft paper, the partition board itself is also prone to small cracks, so in order to minimize cracking in home decoration, it is best to paste a good cloth, if it is a load-bearing wall or solid wall, the reason for cracking may be that the putty is too thick during construction or the interval is short, and the putty is not dry.

For the old wall, the original base putty and paint are required to be removed during the construction, and the base layer is re-treated and then painted.

Is there a crack in the latex paint, or there are cracks in the putty scraped, if the latex paint is cracked, it can be slightly sanded after drying and then brushing the latex paint. If the putty cracks, fill the gaps with putty after drying, and then polish and brush latex paint after drying.

Scrape off the original putty powder, seal the cracks with quick-sticky powder, and after drying, scrape the putty again, paint it, and it's OK.

If the joint is opened, there is no kraft paper tape. You can shovel a little along the gaps, put it on with plaster powder, then stick it with a sticker, then scrape it white, touch it, and paint it.

There are three ways to do this:

1. If the degree of cracking is relatively light and does not affect the appearance so much, you can change after a season after painting, and then repair after the matrix base structure is stable, after all, repeated maintenance will affect daily life.

2. Focus on the maintenance of the base layer: at the cracks, we first clean the base layer, remove the width of 5 cm, pour the V groove at the gap, fill it with elastic caulking paste, paste kraft paper or fiber mesh——— putty on the surface ——- polish and paint.

3. Remove the insulation board on the surface, or remove the cement wall, install a layer of gypsum board or "five-centiboard" outside the insulation layer, and then make latex paint on top.

Causes of cracking of wall latex paint:

1. Cracking of the paint layer.

This cracking is generally a congenital cause. The cracks on the wall surface caused by the cracking of the wall paint layer are mainly caused by the poor quality of the wall paint products and the improper operation in the construction process of the wall paint.

The temperature is too low to reach the film-forming temperature of the wall paint and cannot form a continuous coating film, resulting in cracking of the wall paint. The treatment method is to use fine sandpaper to polish the cracks off if it is only a crack in the surface paint film, choose a wall paint of the same color, and repaint it.

2. Irregular cracks.

This type of crack is also relatively common. You can also remove the insulation board on the surface of the wall, or remove the cement wall, install a layer of gypsum board or "five-mile board" outside the insulation layer, and then paint latex paint on it.

This method can remove all the irregular cracks, but this method is expensive and difficult to construct, and it may be more troublesome if you repair it yourself in the general family. If the latex paint wall cracks at home are not very large, it is better not to use this method.

3. Elastic putty.

This material is relatively unfamiliar to many friends. Another way to repair is to use elastic decorative materials. At present, there is a material called "elastic putty" in the method of wall substrate treatment, which can make up for the problem of wall cracks to a certain extent.

Of course, these materials themselves are less "elastic" and may not be very effective on walls with large cracks.

1. If there is a problem of cracking on the latex paint wall, different solutions need to be taken in combination with the cause and the cracking. Some of them are caused by the temperature environment, in which case we can remove all the paint, including the putty layer. Next, a V-groove is drilled along the crack, and the gap is filled with plaster.

After drying, the surface is pasted with kraft paper, putty is scraped again, and latex paint is brushed after polishing, which can bring about repair.

2. If there is cracking and chalking, it may be that the wall has not been treated, or it is constructed in a low temperature environment, resulting in chalking and cracking of the latex paint layer. In this case, it is necessary to apply a layer of putty after shoveling, and it should be sanded and smoothed. By applying a water-based primer to the back cover, and then brushing two layers of paint on the surface, it can avoid cracking again in the later stage.

There is one less process in your construction, that is, after the first wall leveling, the wall should be covered with non-woven fabrics, and then the putty should be scraped and leveled and then brushed with paint, because the current buildings are all internal wall insulation, if you do not stick the cloth in the construction, the wall must be cracked. It is recommended that you negotiate with the construction team to re-construct in accordance with the construction specifications, and only in this way can you ensure the quality of your decoration.

You can polish it, clean it up, scrape some glue and paste it on the adhesive net, and then scrape the paint and brush the latex paint.

The cracks between the plasterboard and the wall should be treated before applying latex paint. Why didn't the painter put on the bandage, you ask? It is difficult to repair the latex paint after it is brushed.

The walls of my house are also cracked, and the kraft paper has been repaired, and it is still cracked! Given the prevalence of wall cracks, it can be judged that the landlord's house is still good. At least there are no cracks in the walls!

Mend the seams and brush them again from scratch

The painter didn't do a good job, didn't say it.

Wait for it to stop cracking and then paint it with a house taxi wall paint, which I used to do.

Repair it with elastic paint.

1. If the depth of the cracks in the wall exceeds one centimeter, it is necessary to use cement mortar to repair the cracks in the wall one by one, and finally apply the paint on the wall to complete it. 2. When cracks are found, the old wall skin should be shoveled down immediately with a scraper, and then the surface of the wall skin should be polished. Apply the primer to the wall, and be sure to apply it evenly.

1. For the places that are prone to cracks, special treatment should be carried out, and the gaps can be pasted with kraft paper or white latex stickers. If the gap is too large for the tape to stick, it is necessary to mix water and putty powder into a certain proportion of putty to level the wall. In general, plaster can also be repaired, and the unevenness is not more than centimeters.

2. If the crack is very small and in a relatively private place, it can be covered with a painting or a photo frame.

3. If the waterproofing of the home is not done well, so that the water penetrates into the surface of the wall, the wall skin will slowly crack, and then it will fall. Therefore, the wall skin should be removed and the wall should be re-waterproofed. It is not recommended for inexperienced people to carry out repairs, and it is recommended to contact professional staff for on-site repairs.
