The house is more than 20 years old, and it has been renovated for less than a year, and the roof cr

The materials are not sufficient or cut corners, which will make some materials in the house have been weathered and will age, resulting in cracks and rain leakage, so we should not cut corners when building our own houses, and use real materials, so as to maintain value and safety.

First of all, you have to determine the reason, whether the top base layer was not treated well before the redecoration, and the putty or latex paint on the original wall was not cleaned. It may be that the workers disposed of the original wall for convenience.

It may be that the cement used is not very good during the decoration, which leads to falling off, or it may be that the decoration workers are not in place and do not place the roof stone tiles, or it may be that the house is aging, wind and rain, resulting in problems such as its own walls, which pulls the house and causes cracks in the house.

If the house is leaky or damp, it can cause large pieces of the wall to fall off. Solution: First of all, the water should be controlled, then the falling place should be shoveled clean, and then the double white powder should be re-soaked, and the wall paint should be applied.

The big tiled house is really more comfortable to live in than the grass house, with light, warmth, spaciousness, and less gray on the ground, but in the third year, some cracks appeared in the corners of the roof. As time went on, a few cracks appeared in the walls, but they did not have any real impact on the safety of the occupants.

Prefer to spend money on the ground and ignore the foundations underground. The cost of building a house should be 5o 1oo above ground and 5o underground, and my relative is an architect, and he has been talking to me about this for 3o years. Bad teams are also the first choice for cutting corners in foundation construction.

The foundation form is too simple, and it still stays in the past practice, resulting in no way to carry the current rural self-built house load, and after a little longer, there will be all kinds of cracks.

In this case, it has no effect on the main structure, but only on the aesthetics of the wall. If it is effective, it is necessary to repaint the cracked part. As long as the house does not have floor beams and pillars, the foundation will slowly sink, which can easily lead to cracks in the walls of the house.

This kind of phenomenon occurs most often in rural self-built houses, and many of them are also caused by foundation problems.

There are several reasons for cracks in rural houses, one of which is that the foundation works have not been done well. 2. The original soil is not evenly compacted. 3. The homestead is low, and it is flooded when it rains heavily.

Fourth, the homestead has been disturbed in the original strong soil in the past, resulting in the house not being able to sink evenly. The ditch is dug well, the stone and cement are built, and the surrounding soil needs to be built tightly; In this way, it can be built on the green tile house. The foundation of the building must be re-excavated, and if the ground is not hard, the foundation must be made into a ground ring beam after digging.

However, in the past, when building houses in rural areas, because they were generally one-story bungalows with small load-bearing, they were directly excavated, and the foundations were dug very shallowly, and the surrounding areas would not be hard treated, and most of them were directly tamped.

It is likely that there is a serious problem with the material during the decoration, it may be because the decoration style is relatively low, and it may be because the load-bearing effect is relatively poor.

It is likely that the house is too damp and damp that will cause the roof to crack. This phenomenon must be dealt with as soon as possible.

Because the decoration materials are not used well, the materials used for decoration are not qualified, so they are cracked.

Materials: putty, saw.

1. You can see the gaps in the wall.

2. At this time, please ask the construction team to cut the gap and scrape the gap a few millimeters.

3. Then fill it with putty.

4. It is necessary to continue the restoration until completion.

Precautions. 1. Temperature cracks.

Self-built houses belong to the brick structure, the floor and the brick form a binding force on each other, as long as there is a binding force, the outdoor temperature is easily affected, so that it is easy to have the problem of incoordination, so that the brick body is easy to appear temperature force. In the case of temperature gaps on the top surface of the wall, which affects the aesthetics, it is necessary to apply non-woven fabric or mesh cloth to the cracked area first, and then repair the paint.

2. Paint cracks.

If the top surface of the wall is only cracked on the surface of the paint, it is relatively simple to deal with it, just use sandpaper to polish the cracks first, clean the gaps, and then use paint to repaint.

1. Cracks in the wall can generally be covered and maintained by wallpaper, and days.

If you have a flower board, some home decorations will be more noble and luxurious. Therefore, the cracks in the ceiling can be decorated with materials such as gold leaf and silver leaf, but materials that are consistent with the style of home decoration should be considered.

2. If the overlap between the prefabricated slabs is cracked, you can ask the construction team to cut the crack, scrape the gap a few millimeters, then fill it with putty, paste a layer of anti-crack tape or kraft paper, and finally scrape the putty.

3. If the crack of the floor slab causes cracks in the ceiling, then you can report the situation to the property and let them help solve it, if the original structure of the building is cracked, it needs to be repaired. Mainly due to the seams of the prefabricated panels.

When processing, it is necessary to remove the ash first, and re-carry out the ash batch operation, which is best completed at one time, so as to avoid the poor connection between the cement that has dried out and the cement joints on the re-examination, and the problem of cracking.

The house is sinking. For many houses that have been built for a long time, it is easy to subside on the ground, resulting in cracking of the top surface of the wall, which is often at the junction of the floor slab. It is necessary to clean the construction base layer first, carry out anti-crack treatment in the paving kraft paper or mesh cloth, and finally apply the construction of latex paint.

Putty cracks. If the putty cracks the problem, it is necessary to clean the putty on the top surface of the wall first, directly carry out anti-cracking treatment on the surface of the putty, pave the glass fiber mesh, and then re-scrape the putty to effectively avoid the crack problem.

How to deal with cracks in the roof of newly renovated bedrooms:

1. Surface repair method. This method is suitable for narrow joints, used to restore the surface beauty of the component and improve the durability of the use, commonly used is to lay film materials along the surface of concrete cracks, generally can be used epoxy resin or resin impregnated glass cloth.

2. Filling method. When the crack is wide, a V-shaped or U-shaped groove can be chiseled along the surface of the cracked concrete, and the resin mortar material can be used to fill it, and materials such as cement mortar or asphalt can also be used.

3. Injection method. When the crack width is small and deep, the repair method of injecting the repair material into the concrete can be adopted, firstly, the crack is provided with an injection pipe, and the other parts are sealed with surface treatment, and the material is injected with low-viscosity epoxy resin, and the repair is injected with an electric pump or a manual pump. If the crack affects the safety of the structure, the structure should be reinforced.

Let the people of the decoration company make up it, generally after pasting kraft paper and then painting, the operation is quite simple.

Non-standard construction may be the biggest cause of wall cracking, including unsuitable construction environment (inappropriate temperature), wrong construction steps, etc.

The correct process cannot 100% guarantee that the wall will not crack, but if the process is not correct, the probability of wall cracking will be greatly increased.

Many wall base materials are prone to cracking once they are too dry. For example, if the putty is too thick, or the cement is too fast-drying (the process of long-term water retention is generally required for cement to become firm), it is easy to dry, and then depowdering and cracking.

If the putty is scraped too thick at one time, the crack generally appears in the corner of the wall or the uneven surface of the wall, and the crack looks wide in the middle and narrow at both ends.

Shovel out all the cracks, repair the cracks, redo the base layer, scrape the putty, and repair the topcoat. It is equivalent to renovating the wall again, and this method can fundamentally solve the problem of cracking the wall skin, and the process can be more troublesome.

Similarly, if you are afraid of trouble, want to save trouble, you can directly buy some better quality elastic paint on the market, and re-spray it, although this method saves trouble, but the effect is not as obvious as the former.

I contacted the decoration company and the designer as soon as the wall cracked, but fortunately, their feedback was very timely, and I was arranged for a painter to repair it the next day. At this time, we should remind everyone that the latex paint that the painter has adjusted before must not be thrown away, and it must be sealed and covered, otherwise it will be easy to break.

When decorating, the paint must avoid the rainy season, and if it is in the rainy season, it should be dried for a while. Don't rush to brush latex paint. When cutting a new wall, you should also pay attention to let the wall dry thoroughly, otherwise it is easy to crack the wall.

At this time, the repair highlights whether the latex paint is sprayed or brushed, so the repair is not very visible, if it is sprayed, it will be very embarrassing at this time, one by one can be ugly, and the paint master also said that the general crack of spraying is not repaired.

For masonry structure, there is mutual constraint between the floor and the masonry, and in the case of constraints, if the external temperature changes, the temperature deformation between the floor and the masonry is not coordinated, and the masonry will produce temperature stress.

This is the most common crack in the house, this crack mainly affects the appearance of the house, and some remedial measures can be taken appropriately: paste non-woven fabric, PVC mesh cloth, etc. on the crack, and then paint and repair it.

After the wall paint is painted, the window should be opened to allow the wall to form a film in a short time. This cannot be done in the fall, otherwise it will shrink and deform. In autumn, keep windows and doors closed for 1 to 2 days after painting, or ventilate only in the morning and evening to allow the walls to dry.

If the paint you choose at the beginning is relatively ordinary, there is no elasticity and the function of repairing fine cracks, it is more likely to have this problem, so when choosing the coating, you should also choose the supporting function according to the corresponding position, and you can't be careless.

In fact, sometimes it is normal for the wall skin to crack, why do you say that? Because when the heating period is passed, the walls and periods of the house itself contain moisture, and there will be thermal expansion and contraction in the volatilization process. In turn, small cracks will appear in the wall skin, and of course, large cracks cannot be said to be normal.

1. Paint construction is best carried out at a temperature of at least 5 ° or more, if the cement wall is painted, the moisture content of the wall must be below 8%, and the water-based paint is below 10%. Pay attention to proper ventilation during construction.

2. Fill with plaster and hang net stickers in the leveling stage. Generally, there is a greater chance of cracking in gaps, grooves, etc., and these places are filled with caulking plaster or plastering plaster; Then hang a net or sticker, generally hang a net at the water and electricity line trough, and paste kraft paper at the gypsum board.

3. After scraping the putty, use sandpaper to polish the wall. The traditional large white wall can be polished at any time after drying. However, the water-resistant putty commonly used now is very hard after drying, and it is recommended to polish it when it is 90% dry.

This is a common phenomenon, because the moisture in the season is different, so the shrinkage is not the same, and after a summer when the crack is fully cracked, the overall repair will not be great.

The roof of the house is generally poured with concrete as a whole, and it is unlikely that there will be problems with the roof; It should be a problem of construction, it may be that the roof plastering is too thick or uneven, resulting in uneven expansion and contraction of cold and warm, resulting in cracking or peeling.

When reinstalling the old house, I firmly believe that everyone can do the original wall and floor roof eradication, but for the old house, the roof not only has a large white layer, but also a stucco layer of concrete floor slabsIf the original white layer and stucco layer at the top of the layer are not all eradicated, then the original stucco layer will return to moisture during the operation, and in the middle and late stages, due to the continuous high temperature hazards of the high-rise, the original stucco layer and the new large white layer will cause the situation of the layer, that is to say, the roof white cracks and fall.

The original situation is that the original white layer and stucco layer of the roof have been removed, but after the revision of the white or the crack and peeling of the top of the layer, this reason is that the roof after the removal has not been carefully solved. For the roof after the shoveling, it is necessary to polish and polish all the remnants of the stucco layer that penetrates into the top of the layer, and then apply the wall solid to brush before the operation, as long as this can ensure that the roof does not have problems after reinstallation, otherwise there will be the original roof surface residues and the new white fall, coupled with the continuous high temperature hazards of the high-rise, the new roof cracks and fall off after a period of time.

How fast does it take for your house to be renovated and is it minimalist? Generally in each year from June to August is the rainy season, even rainy days, the moisture in the air is heavy, when scraping the white, the plaster is not willing to dry, must be dried, and then the plaster is dry, I think the duration of your interior decoration is a bit short, whether there are some stages to solve the problem is not in place, if the plaster is not dried on the white, it will cover the moisture inside, the middle and late stages will cause more hair, the wall is very likely to be hollow. If you look at the falling wall, if it's a little damp, that's basically the reason.

It is mainly the joint in the middle of the hollow floor slab, which is cracked by thermal expansion and cold contraction. If in the case of interior decoration, it is better to hang the grid diagram at the joint, if it is not hung, this situation is normal. Before the renovation, there was no bulging and other conditions.

If you want to carry out shoveling again. Check whether there is leakage in the roof exterior wall tiles, and if you want to carry out waterproofing treatmentThe putty layer of the exterior wall is not taken off. If you can carry out shoveling or use waterproof putty to roll the paint once, remember that it must be rolled through.

In the end, you must choose good interior wall putty powder and architectural coatings.
