The wall has been scraped with putty powder once, and it cracks, and now I want to scrape it a secon

The wall scraped putty powder once, cracked, and now want to scrape the second time, the method of treatment: for example, when the wall stucco layer cracks, hollowing, etc., if it is not treated, the putty powder is immediately scraped, and the putty layer is likely to follow the cracking of the wall plastering. Problems caused by wall hazards.

How does the wall affect the decorative design of putty powder on the surface? This problem is actually not difficult to understand, for example, after the putty powder is scraped on the wall, the wall cracks for some reason, and the putty powder on the wall will also follow the cracking.

Cracking phenomenon caused by product quality problems of putty powder. Putty powder is paid attention to by the quality of well-known brands, and the adhesion of putty powder with good quality is relatively strong, and the crack resistance is also relatively high! On the other hand, the efficacy of poor quality putty powder in many aspects is correspondingly weaker, so the phenomenon of cracking is also very related to the quality of putty powder!

Cracking of the wall is most likely caused by the subsidence of the foundation of the house, or the cracking caused by the new wall not being integrated with the structure. The treatment method is to remove the plastering of the wall at the gap, and then hang the steel wire mesh and then batch the putty again. This practical operation can reasonably and effectively prevent the cracking of the wall, as long as the wall is not cracked, the putty powder can be scraped on the wall intact and not easy to crack.

Treatment method for cracking phenomenon caused by product quality problems of putty powder. If it is a product quality problem of putty powder, it must be replaced with a good quality putty powder, but there are many well-known brands of putty powder and each has its own advantages. For this matter, Brother Yu proposed that no matter what brand of putty powder is selected, only some raw materials need to be added to improve the efficacy of putty powder when scraping, so as to ensure the quality of putty powder.

For example, adding some concrete (black and white concrete) or applying special super glue for putty powder during the first scraping process can ensure the quality of putty powder and prevent cracking.

First of all, the peeling and cracking places should be removed, the base layer should be cleaned, and then a layer of putty should be brushed, and then the second brush should be brushed after it is thoroughly dried.

First of all, you have to repair the cracking caused by the first scraping putty powder, because it will shrink and sink after repairing, so after doing a good job in wall construction, you must repair the second time, and then scrape the second time after ensuring that the wall is smooth, only in this way can you prevent cracking.

First of all, the first layer of putty powder should be removed, and the putty powder should be re-brushed when the wall is dry, and the second layer should be brushed after the first layer of putty powder is dry and there is no cracking.

The wall was scraped with putty powder.

There is cracking, and now I want to scrape the second solution: if the wall plastering layer is in the situation, you can first deal with the problematic parts, the way is very simple, just hollow the plastering layer wall.

The cracked area is chiseled off and repaired again, and the place to be repaired is dried and then a new batch of putty is used. Cracking of the wall is most likely caused by the subsidence of the foundation of the house, or the cracking caused by the new wall not being integrated with the structure. The treatment method is to remove the plastering layer at the gap, and then hang the steel wire mesh and then plaster again.

This practical operation can reasonably and effectively avoid the cracking of the wall, as long as the wall is not cracked, the putty powder can be scraped on the wall intact and not easy to crack.

If it is a product quality problem of putty powder, it must be replaced with a good quality putty powder, but there are many well-known brands of putty powder and each has its own advantages, and only some raw materials need to be added to improve the effect of putty powder when scraping, so as to ensure the quality of putty powder. For example, adding some concrete or applying special super glue for putty powder during the first scraping process can ensure the quality of putty powder and prevent cracking! Before batch putty, the wall should be inspected to check whether the wall is basically a product quality problem, such as checking whether the plastering layer has a hollow cracking of the wall, whether there is a phenomenon of sand looseness?

If there are any problems, they should be dealt with before carrying out the work of batch putty.

In order to improve the quality of putty powder can be selected to add a special type of putty powder "additives", in order to prevent cracking, the first time the putty powder should be scraped on the alkali-resistant mesh cloth. The second scraping putty powder belongs to the precise ground leveling, which is used to improve the leveling level and decorative effect of the wall, usually it is necessary to scrape the putty powder twice, and then polish and polish the paint or use other wall building decoration materials to carry out decorative design. Scrape putty on the wall.

It is to wait for the bottom to be hit, but the same quality and quantity can be guaranteed to avoid the quality assurance of future decoration!

The wall needs to be re-treated to determine the cause of the cracking, and if there is a problem with the wall, it needs to be treated with a net.

It is necessary to clean the previous treatment and then renovate it, and be sure to pay attention to whether the wall itself is cracked and whether it needs to be hung with nets.

If the putty cracks, it means that there is a problem with the ratio of the inverse putty, and the putty needs to be re-proportioned at this time. And extra care is required during construction.

There are many reasons for putty cracking, 1. The previous putty is hung up before it is dry, and the dry and wet changes form cracks, 2. Temperature cracks are caused by temperature changes and thermal expansion and contraction;

3. The base layer is not well treated or the wall structure is deformed and the structural cracks are caused by static and dynamic loads.

4. Poor product quality will cause cracks, mostly due to the wrong material ratio.

5. The putty layer is too thick.

6. Many factors such as asympathy of maintenance methods may cause putty cracking.

If it is a lightweight partition wall, generally use nylon mesh cloth or kraft paper, and 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 glass silk cloth or bean bag cloth.

If it is a load-bearing wall or a solid wall, the reason for the 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 should be removed as required, and the original wall decoration of some rooms uses 821 putty, which is easy to powder, peel and fall off, so it should be shoveled off, re-processed and brushed.

In the construction of the wall, we should pay attention to such problems, first of all, the ratio of cement and sand, the best ratio is 1 to 3, improper ratio will affect the toughness and tension of the wall; Then there is to find the ratio of putty and latex paint, when painting latex paint, problems will occur if you add too much water. The circuit transformation should be carried out with the carpentry foundation, because after slotting to leave time for repair, the drying speed and shrinkage rate of cement mortar are different from putty powder, and there will be shrinkage and sag after the first repair, and the second repair should be carried out when the wall construction is done, so as to level the wall and avoid cracking. When there are cracks and other problems in the colored wall paint, the effect of local repair is often not good, because the color wall paint will be obvious color difference when it is repainted.

If there is a crack in the insulation board, use a putty knife to cut the crack, as deep as possible, fill in the gypsum, pay attention to be sure to fill it, fill it evenly, and then use a bandage and nylon mesh cloth to paste the cracked place, and then scrape the putty or do other processes after drying.

1. Remove all the original putty, then re-brush the base layer, paint again, and remember that only when the first layer is dry, can the next layer be smeared, effectively prevent cracks in the inner layer, and do not brush the wall too thick, according to the actual situation. 2. If the crack area in the house is relatively large, then it is better to find a professional master directly to come to the door, and the effect will be better.

Reasons for this:

1. It may be because when the putty is scraped, the next layer is applied without waiting for the previous layer to dry thoroughly, resulting in cracking, or due to the change of indoor temperature, resulting in thermal expansion and cold contraction, resulting in temperature cracks.

2. Or it is not done well when making the wall base, or the wall structure is deformed, or it is possible that the quality of the putty purchased is not very good, and the ratio of water and material is not good when batching, maybe the operation is not very good during construction.

3. Maybe it's too thick when scraping putty, or maybe it's not doing a good job of maintenance, such as not cleaning often, not opening windows for ventilation, etc., there are certain factors.

Abstract 1It may be because the first layer is not properly treated, or the wall structure is deformed, the base layer is not treated well, or the structural cracks caused by the static and dynamic load of the wall structure.

Cracks began to appear on the wall just after the first putty scrape, could it be something wrong?

1.It may be because the first layer is not properly treated, or the wall structure is deformed, the base layer is not treated well, or the structural cracks caused by the static and dynamic load of the wall structure.

2. If the wall is not cracked, it may be because the putty quality is not up to par and the putty spraying is a problem.

How to deal with andJust scraped putty wall cracksCauses.

1. Temperature cracks: This kind of cracks have little impact on the structure of the house. It can be attached in cracked non-woven fabric or mortar cloth crack, and then painted.

2. Crack settlement repair: Cracks must be stabilized after cracks, and the repair can be filled with cement slurry, mortar and polymer gypsum.

1. Look at the walls.

When brushing putty from the surface of the wall, the first thing to check is whether the wall surface is flat. If the wall surface is irregular or has gaps, the wall surface must be repaired.

2. Protect the finished product.

When the walls are painted, some dust or glue from the stove will fall, so it is necessary to do a good job of protecting the finished product inside the house.

3. Preparation.

Before brushing putty, the wall should be cleaned with a steel brush to make the wall dust-free, and then brushed with a uniform layer of concrete interface agent. After drying, you can scrape the putty.

4. Putty. If it is used for a wall with a low degree of flatness, you will need to brush the putty several times to ensure that the wall is flat.

5. Polishing putty.

After a few days of putting the putty on the wall, it will solidify, so after the top wall the next night, start polishing and flatness checking, while crushing.

6. Primer brush.

After smoothing, the primer can be applied and applied evenly.

7. Finish brushing. The top layer should be applied twice, and after a few days of applying the last coat of paint, take care to waterproof, dry and avoid exposure to the sun.

8. Acceptance. Just scraped putty wall cracksFinally, after brushing the putty onto the wall, the wall surface needs to be accepted. After the inspection is completed, it is necessary to verify that the wall surface is flat, there are no joints and that the color is uniform.

1. The first type is to handle the seam filling of the base layer and the filling material without drying. When the inner wall putty is applied to strengthen the hardness, it is easy to make the putty crack. Therefore, we have to wait for the basic drying and then move on to the next step, and the owners sometimes rely on the construction crews for construction, which is the reason.

Just scraped putty wall cracksThe construction requires that the water content of the base layer is less than or equal to 10. Structures that are not drying in the base coat can also cause cracks. It is a matter of proportion, and due to inexperience, substandard buildings will crack.

3. The bottom layer of putty is not dry, the surface layer is dried first, and then the inner layer cannot be dried, which is easy to cause different shrinkage degrees between layers and cracks.

4. The putty brush is too thick, the surface dries faster, and the inside dries slower, which is easy to break.
