What is the cause of cracking of latex paint after brushing?

There are many reasons for cracking of wall latex paint, and the following three are more common:

1. The cracking of the wall latex paint is caused by the dry weather in summer;

2. The structural cracks of the wall itself are caused by the frame structure of the house;

3. The putty powder is not dry at the time of wall alignment, and the construction personnel begin to paint the latex paint and cause cracking, which is completely artificial, and the main reason is that the construction personnel are not too skilled.

To solve the problem of cracking of latex paint, in addition to the factors such as the quality of latex paint is not up to standard, it is the problem of putty

In this case, you need to go to the regular decoration company to find the construction personnel to shovel off the paint and putty on the surface, use non-woven fabric or kraft paper to re-post the cracks, and then scrape the putty, and then paint or spray latex paint after the putty is completely dry, so as to avoid cracks.

1.Putty is made of heavy calcium powder, talcum powder with a certain amount of cellulose and construction glue blended into engineering putty, because of the low cost, easy to use in the construction is widely used, but the quality is basically not up to the finished putty national and industry technical specifications requirements. 2.

In the case that there are no cracks in the wall and no cracks in the putty powder, it is the problem of latex paint, but the latex paint itself is only a semi-finished product and needs to be used with water.

Hello, glad to answer for you! Cracking may be caused by the following reasons: 1. The putty is not dry thoroughly, resulting in cracking. 2. There are cracks on the wall, and the cracks cannot be patched well when the wall is treated. 3. There are many decorations on the same building, and the house sinks;

4. After brushing the latex paint, the window should not be opened widely, and the window should be left with a small gap for ventilation, so that the putty and latex paint in the wall can be slowly dried. 5. The mixing ratio of latex paint is wrong, and the application is uneven 6The latex paint brush is too thick and can also cause cracking, I hope mine can help you!

Putty layer cracking: Putty layer cracking is usually caused by the putty layer being too thick, or improper application. Many people think that the thicker the putty, the better, the putty is easy to absorb water, and the putty that is too thick is too absorbent, absorbing the moisture in the air, which is easy to lead to thermal expansion and contraction, which in turn leads to cracking.

Solution: Remove the cracked putty and reapply the putty. If the cracks in the putty layer are not serious, you can also use flexible putty to apply first, and then carry out construction according to the standard construction method.

The reason for the cracking of the paint layer is mainly the difference between the dry and humidity of the paint inside and outside, there are generally two situations, one is that the construction process is not standardized, for example, the latex paint is too thick in a single pass, and then the interval between two coatings is too short, and the other is that there is no problem in the construction process, but the window is opened before the paint is dry, which will cause the surface of the latex paint to dry quickly, thus cracking.

Precautions during the use of paint

1. All kinds of paints and other flammable and toxic materials should be stored in a special warehouse and should not be mixed with other materials. Volatile oil should be packed into a closed container and properly stored. The paint and coating warehouse should be well ventilated, no one is allowed to live, and fire-fighting equipment and "no fireworks" obvious signs should be set up.

The warehouse should be kept at a safe distance from other objects.

2. Because many organic solvents in paint are flammable substances, do not smoke or use open flames at the construction site to prevent fire or **.

3. When using kerosene, gasoline, rosin perfume, banana water and other flammable materials, protective equipment should be brought, and smoking is not allowed.

4. When spraying nitro paint and other volatile and flammable solvent coatings, it is not allowed to use open flames or smoke.

Causes of latex paint wall cracking:1. There are gaps in the insulation layer of the wall, and the paint is not treated well, resulting in cracks in the latex paint.

2. After the wall is slotted, there is a problem with filling, and the wall shrinks and cracks.

3. If the cement ratio is not correct when plastering, there will also be wall cracking.

4. There is a problem with the ratio of latex paint and water, and it will crack after painting.

Latex paint construction precautions.

1. Before the construction of latex paint, it is necessary to do some treatment on the wall, such as the uneven wall, it needs to be repaired in advance, and the wall has more dust and stains, and it should be cleaned up in advance. And because of the different paints, the use method is also different, so it is necessary to read the instructions in advance.

2. When purchasing paint, it is best to measure the approximate amount of brushing, and then buy more, so that it can be used in the later stage. Try not to buy paint in different stores, otherwise even if the color is the same, it is easy to make errors and affect the overall aesthetic effect.

Nowadays, there are many choices for wall decoration, including latex paint, diatom mud, wallpaper, integrated wall panels, tiles, etc., and latex paint is more popular among the public group, with good decorative effect, simple construction, cheap, simple renovation and other advantages, but if latex paint does not pay attention to construction, it is also prone to cracking and other problems, so what is the reason for latex paint cracking? What should be paid attention to in the construction of latex paint? Let's take a look with Qeeka Home experts.

1. What is the cause of latex paint cracking?

There are reasons such as the unstable base putty, the cracking of the damp substrate, the improper maintenance of the coating, and the excessive water added to the latex paint. Generally speaking, the latex paint itself will not have the problem of cracking, and most of the latex paint cracking is because the base putty layer is cracked, which spreads to the coating, resulting in the cracking of the surface latex paint.

Second, what to pay attention to in the construction of latex paint.

1. Pay attention to grassroots treatment.

The construction of latex paint has relatively high requirements for the base layer, and the original base must be removed cleanly, and the putty layer needs to be coated and polished before construction. If the original paint layer of the new house is intact, there is no need to eradicate, you can use a ruler to check whether the original base is digging, as long as the error does not exceed 5 mm, you do not need to remove the original plastering layer.

2. Pay attention to paint blending.

The preparation of latex paint paint is relatively simple, only need to add water to dilute it can be used, but there are strict requirements for adding water, if the amount of water is too much, the paint can not be well attached to the wall, and it is very likely to affect the gloss, hiding power, film-forming and durability of the coating, etc., so before adding water to mix, it is necessary to read the relevant instructions of the product carefully, and add water according to the instructions for use.
