Why do ceilings and walls in your home crack and latex paint warp?

A: It may be due to the weather or environment, humid weather and other conditions will make the wall crack. Or it is the reason for the quality of latex paint products, if the quality is not good, it is easy to crack and warp.

Because the wall foundation is not well treated during decoration, it may not be polished flat, resulting in two skins when painting.

Because the quality used at that time was not particularly good, this situation occurred after air drying.

This is a common situation where latex paint is hollowed out and peels off. The main reasons for this are:

1.The problem of the contact surface of the grassroots: the wall is not clean when the latex paint is applied, the workers are lazy, and the wall is not polished and cleaned, resulting in the weak adhesion of the latex paint;

2.Weather or environmental problems: During construction or use, long-term exposure to a humid environment leads to excess moisture in latex paint, and when the wind blows or the weather is dry, the latex paint will shrink and tighten, resulting in peeling.

For the former phenomenon, it is better to consult during construction, and in the latter case, for example, to brush latex paint in the bathroom, you had better choose waterproof latex paint.

3.Wall cause: Although your wall is a new wall, it does not exclude this reason, and a bad wall will also cause the surface to crack and fall off.

4.Reason for latex paint products: Don't say much about this reason, you choose not good paint, fake and shoddy products or brands with poor qualifications.

5.The putty layer problem, as the saying goes, seven points of putty and three points of paint, good paint also needs good putty. The original white ash wall has not been eradicated, the wall base is not clean, the dust layer is not cured, the dust layer is attached, and the original latex paint layer is separated from the new putty layer.

If you want to deal with your situation, you can ask the master of the Meitushi Refresh Service to help you do a basic inspection, find out the cause and then re-deal with it.

Damp, coupled with the fact that the air conditioner is turned on and off, the heat expands and shrinks, and it is strange that it does not peel.

There are several reasons for your question:

1. When I started to do it, the base wall was probably not dealt with well!

2. The cement is too dry!

3. Start making paint before the base layer dries!

The best way to deal with it is to find out the reason, then remove the surface layer and repaint it!

It is better to use non-woven fabrics.

Treatment of cracks in insulation boards. Use a putty knife to cut the crack as deep as possible and fill it with plaster. Pay attention to be sure to fill it up and fill it evenly.

Then use a bandage, bean cloth or white cloth to paste the cracked area, dry it, and then scrape putty or do other processes. If the crack is severe, you can also use kraft paper or newspaper to repair the joint, the effect may be better.

The reason for the cracks after the trunking is that the drying speed and shrinkage rate of the cement mortar are different from the putty powder, and the putty on the surface of the wall has been dried, and the cement mortar inside has not dried thoroughly, so cracks appear. Therefore, the effect of gypsum powder for the wire repair duct is better.

Cracks can also occur if the wall putty is scraped too thick at one time, or if the thickness of the entire wall is too different. In severe cases, it will also fall off. If necessary, you should scrape several times, each time thinner and longer.

However, it should be noted that the putty is scraped more times and is easy to fall off.

It is estimated that when the paint part was renovated before, the wall putty was not dried thoroughly after batching, so it was done continuously.

If it's a large area or a foundation, it's a headache.

Partially, you should first remove the original shovel clean, anilox tape or kraft paper, paste a good glue, re-batch, dry thoroughly, sand flat, and then apply latex paint.

These are caused by improper decoration processes or poor materials.

Just believe in the profession, if you want to be afraid of anything, you don't care about it, everyone will have this problem, it's normal, everyone looks at your crack every day...

Looking at what you said, I think there is a problem with the caulking tape and construction process used.

It is recommended to use a self-adhesive caulking tape of that mesh cloth. This caulking tape, which does not use a white latex emulsion, does not need to be dried.

In your current situation, it is estimated that you are using the kind of white cloth strip or paper caulking tape, which is connected with white latex emulsion. This kind of caulking tape generally needs to be dried before the putty can be scraped, otherwise it is easy to crack and wrinkle.

It is recommended that you buy mesh self-adhesive caulking tape and try it. During construction, the base layer should be thoroughly cleaned, and the original putty powder or caulking gypsum should not be retained.

There is a kind of plastic corner strip, first paste it with sticky powder, and then scrape the putty after drying! This is the first to do a good job of the grassroots!

Decoration of the ceiling wall cracking, different wall cracking treatment methods:

1. Cracking at the joints.

Cracks in the base layer of wall joints can lead to cracks in the surface of the wall. The cracking of the joints mainly occurs at the joints between the reinforced concrete shear wall and the ceramsite bricks, the joints between the reinforced concrete beams and the ceramsite bricks, the doorways of the back blocking, and the joints between the gypsum board partition wall and the original wall. The cracking of the joints is mainly due to the influence of the surrounding environment or external forces, gypsum boards, prefabricated partition panels and prefabricated floor slabs will shrink and change their positions, resulting in cracks at the joints, which are generally vertical joints or horizontal joints.

Solution: It is recommended to wait for the deformation of the whole building to stabilize after the repair, and the repair within a short period of time is prone to recurrence.

2. Cracking of the wall structure.

Cracks in the structural layer of the wall itself can also lead to cracks in the surface wall. There are two situations, one is that the original wall itself has cracks, and no appropriate treatment measures have been taken in the later decoration process; Second, the original wall was decorated without cracks, but cracks occurred in the later stage due to uneven foundation settlement and large temperature changes.

Solution: This kind of cracking can not be repaired by ordinary decoration methods, and it is necessary to find professional building structure personnel to take corresponding measures according to the actual situation.

3. Cracking of the putty layer.

Wall scraping putty can make the wall more smooth and delicate, and the flatness is much higher than that of the cement wall, so that the wall painting effect is better, and it also saves paint. If the putty layer cracks, it is also easy to cause cracking in the surface layer. Therefore, it is necessary to pay attention to avoid cracks in the putty layer during construction.

Treatment: If the crack has penetrated deep into the putty layer, you can first use a sharp tool to expand the crack to a cone size, fill in the caulking plaster and polish and level, paste the mesh cloth or kraft paper and then use putty for leveling, and finally paint or paste wallpaper according to the normal process.

4. Cracking of the paint layer.

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 construction process of the wall paint.

Treatment: If it is only a crack on the surface of the paint film, use fine sandpaper to polish the crack off, choose the same color wall paint, and repaint it.

5. The plastering layer is cracked.

The cracks of the wall plastering layer are divided into two types: normal cracking and abnormal cracking, and normal cracking mainly refers to the cracks in the plastering layer caused by the shrinkage of cement mortar; Abnormal cracking is mainly caused by improper materials or construction technology. Normal cracking is difficult to avoid, but abnormal cracking can be avoided.

Treatment method: If there is a large area of hollowing in the plastering layer, the original plastering layer should be knocked out, the plastering layer of cement mortar should be redone, and then painted according to the normal process after leveling. However, the cost will be relatively higher after this treatment.

If there is only a small area of cracking, there is no sand turning, hollowing, and falling off, you can paste a good cloth all over the wall, and then paint according to the normal process.

The day before yesterday, a fan, Mr. Xu, consulted Brother Pin, saying that during the decoration, the elders in the family kept saying that the ceiling should be installed, which can not only hide the line but also look good and atmospheric. But after he did it, he found that the ceiling had a sense of "pressing the top".

Because Mr. Xu has a meter high ceiling in the company, there is only rice in the living room at home, and only rice is left after the ceiling is done (only measured after the disadvantages).

Pressing the ceiling.

Here, Brother Pin has to say that the height of modern commercial housing is about one meter, and after the floor and tiles are paved, there is already a sense of depression. If you do simple European style decoration like Mr. Xu, then with the retro luxury European chandelier, there will inevitably be a sense of "pressing the top".

Why install ceilings.

Domestic decoration generally has the concept of home decoration as a ceiling, mainly caused by two factors:

One is: the elders in the family "suggest" to do, the ceiling concave shape is shining, it looks magnificent at home, and it does not arrange the rent slag stalls except for what they think looks good (do not spray).

The second is: the decoration company "suggests" to do it, and the construction party may not ask you "Do you want to do the ceiling?" More will directly ask you "whether the ceiling should be tiled or shaped", which is a metaphor for self-experience, and Brother Pin will not be thorough here.

In fact, there is no standard answer to whether the ceiling looks good or not, but the owners should understand that the house is your place to live in the next few decades, so that you feel comfortable and spacious.

It is advisable to do less ceilings.

The high cost of labor and materials for making ceilings often exceeds your renovation budget.

Some of the ceilings are made of wood, which may be unenvironmentally friendly such as formaldehyde.

Most people will not observe the ceiling after a few months of renovation, and even will not turn on the light strip and chandelier in the ceiling in order to save electricity.

The function of the ceiling is to hide all kinds of water and electricity lines and air conditioning pipelines, if you don't install the ceiling, you can directly make shallow grooves in the cement wall and bury the pipelines in it. (There are precautions for wall slotting at the end of the article).

Is it nice not to make a ceiling.
