Cracks appear on the wall that has just been renovated, how should I solve them?

It has a lot to do with the construction, first of all, the base layer is not well handled, such as the load-bearing wall and the non-load-bearing wall are not hung with nets, the wall slotted is not hung with nets, and the combination of the base and the stucco layer is not good. 2. The bottom leveling is all with putty powder, which leads to cracking caused by the putty powder being too thick. Generally, after rolling the wall paint, the room should be closed for a few days to let the wall paint dry naturally.

In a ventilated environment, the wall paint dries and passes through quickly, resulting in expansion joints. If there is a crack in the ash layer, you knock it down with a hammer and drop the whole piece of dust, which is a problem with the quality"Hollow drums"。If the dirt is not dropped in its entirety, it is not a quality problem.

<> is a normal phenomenon, because there are also decorations and shopping upstairs, gravity pressure makes the wall cracks, large flat cracks are rare, if you don't want to wall cracks or reduce cracks, before painting the whole house sticking net. If there is a problem in the later stage, it is necessary to remove the hollow drum part, repaint it, hang the grid cloth putty, and paint it. If it is a putty base treatment problem, the putty base layer should be eradicated and reprocessed.

When the corner of the wall is in masonry, tensile ribs should be arranged, and when the width and height exceed two meters, the tensile structure beams and columns should be added. Such problems are the main cause of cracking. However, if there are continuous deep cracks, or if they appear on the outside of the building in a vertical penetration, then the problem is not good.

It needs to be reported to the competent authorities in a timely manner.

If your home is a brick-concrete structure, the cracking of the two walls may be caused by unreasonable foundation settings or unreasonable structural stress, first observe whether there is any further development trend, and if so, start from the source, whether to strengthen the foundation or replace a component. There is also a wall caused by our decoration, and the plastered ash and bricks are smashed separately without paying attention! Paint it straight away!

This will definitely crack the surface! Stuff No. 10 or No. 8 steel bars into the seams on both sides, tie them into a centipede shape on both sides, then clamp the wooden boards on both sides, and finally pour wet cement mortar into the upper opening, remove the board after drying, and then smooth the transverse groove with cement mortar.

It is definitely necessary to find out the relevant cause, and if the putty is not scraped well, the putty should be scraped again.

I thought I had to go to the renovation company to inquire, because it cracked just after the renovation was done, and it was their problem.

Cracks should be treated with wall adhesive adhesive so that they can be effectively solved and will also make them look good.

When the walls are not completely dry when decorating the house, we should water the walls from time to time, so as to avoid such a thing.

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.

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.

The above isCracks appear in the renovated wallsA summary of how it should be resolved. I hope everyone can use it.

The main reasons for the cracks are: the base is not firm, the wall is too thin, the structure of the house is unreasonable, the wall is not dry, and the cement is painted!

Foam on the walls: The walls have blister-like protrusions and also contain grains of sand that fall off when touched. The cause of wall foaming is that too much pigment is added to the paint formulation or mixed with debris; Paint buckets, brushes, rollers or spray guns are not clean; Before the paint surface dries completely, moisture seeps into the paint and the paint film loses its adhesion.

Do not clean the walls when painting, etc.

The walls are peeled off: sometimes the renovation is completed quickly, and putty floats on the walls. The main reasons are poor construction technology, poor putty adhesion, low paint adhesion and shrinkage.

Wall cracks: Cracks in the walls of new homes are a common defect in renovation. There are many reasons for this. It may be that the wall is too thin. The wall cement may not be dry before it is bonded, or it may be the original building structure.

Next, after finding the cause of the crack in the wall, you can prescribe the right medication and take different repair and ** measures according to different causes. If the base layer is not strong, all the base layer must be removed and renovated. In other words, the cracks in the base of the wall are too large, which seriously affects the safety of family members, and must be dealt with by the relevant decoration company.

If the base layer is strong, you can first observe whether the cracks in the code hall have a tendency to expand. If not, you can fix it directly with plaster powder. If the crack keeps expanding, it can be repaired with a polymer repair mortar!

Of course, if friends can't take the time to fix these cracks, they can decorate the walls with wallpaper and cover the cracks. But this method can only mask appearances, not a good one.

The reason for the cracking may be that the ratio of cement to yellow sand is wrong when painting the wall, resulting in cracks in the cement mortar causing cracking of the latex paint. Treatment method: First remove the putty layer, and after seeing the cracks in the cement mortar layer, you can directly paste it with a carbon fiber anti-crack cloth, so that it can be treated.

Cracks appear in the surface paint film. In general, dealing with problems is relatively straightforward. You can use fine sandpaper to wipe the cracks and repaint them with latex paint.

Flooring and masonry are mutually restrictive. If the outside temperature changes under constraints, the temperature between the floor and the masonry will also be uncoordinated. When the temperature stress exceeds this limit, your masonry will have temperature cracks.

Treatment: This is a common type. At this point, non-woven fabrics, PVC mesh, etc. can be attached to the cracks, which can then be repaired with a paint brush.

The expansion joint between the structural wall and the brick wall extends to the surface of the wall, which is usually a crack formed by latex paint. When such cracks occur, you should find a professional building structure personnel according to the actual situation, so that you can take appropriate measures.

Treatment: Relatively speaking, this type of crack is more complicated. When processing, you need to remove all base layers.

It is necessary to clean the cracks. The epoxy is then filled into the gap, and carbon fiber is used on the surface of the gap. The cracked fabric is reinforced, and when it is done, it can be repaired with latex paint.

Causes and solutions for cracks in the walls of the newly renovated house:

1. Temperature cracks. Common house cracks, has little impact on the safety of the house structure, this kind of cracks, only affect the interior appearance of the house, will not affect the safety of the house, can be appropriately adopted some remedial measures: in the cracks pasted non-woven fabric, posted PVC mesh cloth or mortar to plug the joints, and then with paint for repair.

2. Settlement cracks. When the settlement crack develops slowly and weakens after the occurrence of the settlement crack, the crack should be corrected after the crack is stabilized. It will take 2-5 years for the foundation of a new house to gradually settle, and you should not worry too much about this after the cracks are repaired, during which time the walls may still crack due to the subsidence of the foundation.

If the crack has little effect on the overall beauty of the house, it can be repaired after the first repair. Corrections are usually filled with cement mortar, polymer mortar or elastic putty, gypsum, and caulking tape is posted.

3. Structural cracks. Ordinary decoration methods cannot be corrected, and it is necessary to find professional building structure personnel to adopt corresponding measures according to the actual situation.

4. Cracks in the appearance of latex paint. Wallpaper cracks: If there are only cracks on the surface of the paint film, use fine sandpaper to polish the cracks off and paint them from scratch. If the wallpaper is cracked at the joints, moisten it with warm water and apply the wallpaper glue from the beginning.

5. Putty screed cracks. If the crack has been deepened into the putty layer, you can first use a sharp object 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 then paint or paste wallpaper according to the normal process.

6. Cracks in the plastering layer of cement mortar. If the plastering layer presents a large area of hollowing, the original plastering layer should be knocked out, and the plastering layer of cement mortar should be made from scratch, and then painted or wallpaper according to the normal process after leveling. However, the cost will be relatively progressive, and the owner can choose the repair method according to his own economic ability.

If there is only a large area of cracking, there is no sand, hollowing, or falling, you can paste a good cloth all over the wall, and then paint or paste wallpaper according to the normal process. The relatively low cost method is to nail a layer of gypsum board directly on the original wall, which requires environmentally friendly milky white rubber and steel nails to be used together.

7. Cracks in the joints. It is advocated that the deformation of all buildings tend to be corrected after stability, and the correction within a short period of time is simply repeated.
