After the house was renovated, cracks appeared on the surface of the wall again and again! What s th

The best solution is to find out what the cause of the crack is.

1. If the wall paint cracks due to the cracking of the wall itself, then repair the wall.

2. If it is a quality problem with the wall paint, then repaint the wall paint.

3. If there are other reasons, the reasons will be dealt with first.

cracking, the source cause must be treated before the others are treated.

Wall cracking is a common problem encountered in decoration, first of all, to see whether it is a developer's problem, such as unqualified cement mortar caused by the wall valley, if so, must be the valley of the valley to remove the place to do again, because the old and new cement can not be combined, then before the approval of the wall should also be pasted with special paper at the gap between the old and the new, so that there will be no cracking in the later stage. If it is a crack in the wall that has been done, it is best to rule out the developer's problem, and it is best to let the cracked wall be re-shoveled and repaired.

In fact, the cracking of the wall is often caused by an inexperienced master, and the experienced master will tell you how to deal with it in advance when he finds that there is a problem with the wall.

It depends on where the problem occurs, if it is a problem with the quality of the house, you can only go to the developer or the property and ask him to solve it for you.

If it's due to the decoration materials, then they have to be redecorated...

Due to the change in the original layout of the house, then it has to be demolished. Re-get...

I believe that many friends have experienced this kind of problem after the decoration of the new house, that is, some of the new houses have not yet moved in, and there are cracks on the wall, and some friends may have a better wall, and there will be cracks when they stay for a while, in short, this problem will be very headache after this problem, because when the oilman master deals with it, there will still be such a problem soon, so what should I do if there are cracks on the wall after decoration? The master said that this treatment can never crack.

Generally, the position of the gap in the wall, most of them are at the joint between the beam and the wall, of course, other positions may also occur, this is mainly caused by the wall base is not treated, and the treatment method used by the master is to remove the surface of the cracked position and the cement powder layer, and the size of the shovel is greater than the size of the crack, if the position is just the joint with the beam, part of the powder layer of the beam must be completely removed, if it is only to remove the wall putty layer, then it is useless. Because the crack expands from the inside out, the inside has to be dealt with.

After shoveling off the wall powder layer, the master lays the steel wire mesh at the cracks, increases the tensile force of the wall and the beam, and uses high-grade cement to re-treat the powder layer, and finally let the oiler master repair the wall.

Xiao Shi said: so we decorate the new house, the wall will also have this kind of problem, you might as well use the master's treatment method to try it, basically can solve the problem, in fact, this situation, we can completely avoid it when decorating, that is, when receiving the wall, the wall is hollow drum detection treatment, if you find that there is a hollow drum situation, you must remove the powder layer and then deal with it, especially the joints between the beam and the wall, it is necessary to focus on inspection, if the whole wall is hollow, it means that the wall has sunk, It is better to dismantle and rebuild.

Use gypsum block dry powder to plug the void, the filling depth is not less than 30-40mm, and there is no need to fill it with the wall, which is lower than the wall.

Decoration is also known as decoration or decoration. It refers to a set of construction plans and design schemes carried out in a certain area and scope, including hydropower construction, walls, floors, ceilings, landscapes, etc., and formed according to certain design concepts and aesthetic rules. From the placement of furniture and the orientation of doors, to the customization of room accessories and lamps, they are all the embodiment of decoration.

Decoration is different from decoration, decoration is the artistic processing of daily necessities or living environment.

Strengthen the aesthetic effect, and improve its functional, economic value and social benefits, and take environmental protection as the design concept. The perfect decoration should be closely integrated with the function of the object, adapt to the production process, give full play to the properties of the material material, and have a good artistic effect.

It is difficult to repair cracks in the wall that has been renovated. In general, it is to brush the latex paint again, but this effect is not ideal and cannot solve the problem in essence. It should be decorated, and it is best to cover it up.

Home renovation is a big project, and if it is not handled properly, there will be many problems. In life, we will often see the phenomenon of wall cracks, which will not only affect the beauty of the entire home decoration for a long time, but also have some hidden dangers in the safety of indoor life. Therefore, we found that when cracks appear in the wall of the house, it must be dealt with in time, and the causes and treatment methods of wall cracks are detailed below.

The cause of wall paint cracking has a lot to do with the quality of the paint, if the quality of the wall primer and topcoat is not good, the later paint layer is prone to cracking. In addition, improper construction operation or improper proportioning of the wall surface when applying the topcoat can also lead to cracking.

If the temperature in the room is too high or too low or the humidity is too high during construction, the paint layer will dry slowly, resulting in cracking. Use a scraper to remove all the sub-layers and paint of the cracked wall, and then repair and smooth the cracks in the wall with cement mortar, and after the cement mortar is completely dry, then use a hanging net or a nylon mesh with high paste strength to deal with it, and finally hang a putty on the wall, and then apply a brush. The quality of the putty powder is not up to par, and the wall will be hot after a long time.

Too much water is added to the putty, which makes the expansion ability worse, or the putty layer is scraped too thin or too thick during construction, which is also easy to cause cracking. If there is a problem with the quality of the cement mortar material, then there is a high possibility of cracking in the later stage. In addition, when carrying out wall plastering construction, if the proportion is improper or the construction process is improper, it will lead to later cracking.

If there is a large area of hollowing in the plastering layer, the original plastering layer should be knocked out, a new layer of cement mortar plastering layer should be made, and then painted according to the normal process after leveling.

If it is only a small area of cracks, you can cover the wall with polyester cloth and then paint it according to the normal process. The cracking of wall joints mainly occurs at the joints of reinforced concrete shear walls and ceramsite bricks, reinforced concrete beams and ceramsite bricks. There are also new walls and old walls splicing, and the shrinkage rate is not the same, which will lead to cracking.

It may be because the solar radiation is too large, but fortunately, it is too humid, there are dust impurities in it, and there are problems with raw materials; First of all, we must find out the reason, if it is because it is too humid or the temperature is problematic, we must open the window in time to ventilate or carry out shading treatment, and if there is a problem with the raw materials, we must replace it in time.

It is caused by the poor paint used on the wall, or it may be caused by the spread of strong face, it may be caused by pressure, it may be caused by noise, or it may be caused by the decoration of the upper floor. The walls can be sanded or repaired.

I think it may be due to the poor flatness of the wall, the temperature in the home is too high, and the quality of the putty used in leveling is not very good, or the putty layer of the wall is not dry and the construction begins; In this case, you can remove the putty from the wall, re-shape it, and re-apply the wall again.

Cracks appear in the renovated wallsVery annoying. Wall cracks not only affect the use, but also have hidden dangers to the safety of the building. Therefore, it is necessary to deal with cracks in the walls.

Cracks appear in the renovated walls

1. Paint cracks. Cracking of the paint is normal. Cracking of the coating is mainly due to cracking of the wall surface due to unapplied coatings and non-standardized steps in the structure.

Cracks in the walls caused by cracked paint are relatively easy to resolve. But it can be said that the cracks in the walls have penetrated the putty layer. Use a sharp tool to extend the crack to the size of a screwdriver, then fill and polish the caulking mesh and secure the net.

After the fabric or kraft paper, use putty horizontally, and finally paste the wallpaper.

2. The wall is broken. A crack in a finished wall basically means that there is a crack in the wall and a crack appears in the wall. This is the case when the cracks caused by the foundation and geological changes of the building are completed.

Another reason is that the walls themselves have cracks and have not been properly treated during the subsequent renovations. This type of wall cracking is more serious and must be addressed by a professional according to the structural conditions.

3. The seam is broken. Destroying a wall will cause the surface of the wall to crack. If left untreated for a long time, it can cause cracks in the surrounding building materials.

This kind of crack does not have to be too worried, because it is a crack in the joint, but it must be taken into account that the deformation of the entire building tends to stabilize and repair, and the repair is easy to repeat in a short time.

4.The paint layer is cracked. A crack in the coating is a crack in the coating.

The cracks in the paint are mainly putty, and the cracking of the paint layer is mainly due to insufficient construction specifications and poor paint quality. In this case, it can be fixed even if it is just a surface. Break the paint film, crush the cracks with fine sandpaper, choose the same wall paint and repaint.

IfCracks appear in the renovated walls, you have to change the paint on the wall or confirm the problem during the renovation process.

Wall cracks are the cracking phenomenon caused by the wall part of the building structure, which can be divided into the following four reasons according to the different materials of the materials themselves. Cracks in concrete walls, cracks in brick masonry walls, cracks in new partition panels, cracks in walls of different materials.

Patching Steps:

If there are cracks in a large area, the crack will be chiseled into a "U" shape on the base of the wall, and the spacing of the "U" groove is greater than 20cm, and the chiseled base will be chiseled, and then the steel wire mesh will be hung. The cracks are then painted with elastic decorative materials to compensate for the cracks in the walls.

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

Shovel off the cracked paint film, fill the cracks with elastic putty, use elastic wall paint for construction, and use primer for the base layer with too strong water absorption, so as to avoid construction in the case of high temperature and low humidity, the paint film can not be too thick when painting, and pay attention to avoid excessive atomization when spraying.

This answer is applicable to the method of repairing cracks in the renovated wall.

Abstract The shrinkage of materials, now many insulation masonry have a high proportion of shrinkage, and the duration is also very long, like the shrinkage of concrete will last for several years. The other is temperature difference cracks, such as the top floor of the house, the roof and the indoor temperature difference is very large, and the temperature difference in summer and winter will cause cracks and cracks.

Why do cracks appear in the walls of a renovated house, and they will crack again after repair?

The shrinkage of materials, now many insulation masonry have a high proportion of shrinkage, and the duration is also very long, like the shrinkage of concrete will last for several years. The other is temperature difference cracks, such as the top floor of the house, the roof and the indoor temperature difference is very large, and the temperature difference in summer and winter will cause cracks and cracks.

<> (1) Shovel wall skin: During construction, the wall skin around the crack is disposed of, and then the treatment of the wall base layer is continued, which can prevent the wall from cracking again, and can make the wall and the paint film better bonded. (2) Coating interface agent:

After the wall skin is removed, the base layer is cleaned to ensure that the base layer is free of dust and stains, and then the interface agent is applied. This can not only facilitate the better adhesion between the interface agent and the wall. (3) Filling leveling:

Wait until the interface agent is dry, and then carry out filling and leveling treatment, and when the worker is constructing, the concave place can be filled with quick-drying powder, and a layer of leveling treatment is more conducive to subsequent construction. (4) After the leveling is completed, a layer of fiber net is laid on the base layer. (5) Leveling again:

After laying the fiber net, the uneven places on the wall are completely smoothed out after leveling once. (6) Painting: After the leveling is completed, it can be painted.

The junction between the infill wall and the frame structure usually has some horizontal or vertical cracks due to the physical properties of the two materials (different degrees of thermal expansion and contraction, you know). Hollowing when plastering is also one of the reasons. The method of handling is generally:

During construction, hang steel wire mesh in the plastering, which is what we call hanging nets, and sticking kraft paper or white cloth in these places when applying putty during decoration can also reduce the occurrence of this situation. If it happens, then it is likely that the developer did not hang the net and the decoration was not dealt with.

There is also the wall to open the trunking, there will be cracks with the trunking without treatment, it is recommended to plan carefully before decoration, less open the trunking.

However, such a crack does not affect safety, and even if it is treated, it may appear after a few years, and I usually don't see it.

The most serious are structural cracks, which are generally divided into temperature cracks and settlement cracks.

If such a crack appears, it is a problem of the house itself, and it is useless to deal with it even when decorating, which is also very dangerous.

Such cracks generally appear on the top or bottom floor, on the exterior walls, at the corners of doors and windows, either small or large, or large or small.
