What should I do if there are cracks in the ceiling? The ceiling is cracking, what should I do?

Remove the crack-proof putty that was originally cracked. Re-patch the seam with anti-crack putty and then apply it with gauze or kraft paper. I recommend that it is best to use kraft paper, and also, the putty used for repairing joints should not be made of gypsum powder, and some people use it for the convenience of construction and saving money.

Be sure to use a special anti-crack putty. As; Putty or something. Be sure to polish it after making it up.

It is best to polish the ceiling as a whole. Then use ici for construction. It is best to do it at least three times.

Personally, I think that the cracks in the ceiling belong to the common problems in the decoration, as long as it is not very serious, it is not recommended that you give maintenance, the repair will make your surrounding hue different, if it is really serious, it is recommended that you soften your ceiling according to your own style.

The use of gypsum board ceiling in your construction must be built with building gauze and white glue; After drying, use the wire anti-cracking putty on the outside twice on the outside; Use fine sandpaper to smooth the surface treatment each time. When the latex paint is reconstructed, it is necessary to pay attention to the weather humidity, and when the humidity is relatively low, the construction will be OK, and there will be no cracks in your ceiling. If you already have cracks, it is recommended that you use the same brand of latex paint to apply again, but the symptoms are not cured.

If you rebuild, you will waste money and time.

Engaged in decoration all know, gypsum board ceiling is not easy to maintain after the cracking phenomenon, the key is to pay attention to the structure of the construction firm, outside the paint construction should also pay attention to the construction points.

It is common sense that the joints of the gypsum board must be caulked when the ceiling is suspended, otherwise it will crack.

Cracks in the ceiling, I believe it is not a difficult phenomenon to encounter, many owners see the cracks in the ceiling overhead, a panic, calm! Today, let's talk about how to repair cracks in the ceiling!

1. If the surface of the paint surface is cracked, its state is linear, angular or irregular cracks, then the problem is not very serious, the reason for this phenomenon may be because the paint surface is too thick, or it may be that the base is too rough, and the result is that the primer and the topcoat do not match. In this case, we should remove the paint film and then reapply a new primer, always make sure that the primer is completely dry before applying it again, and it is not recommended to apply paint when the temperature is below 5 degrees Celsius.

2. In addition, cracks in the ceiling may also be caused by temperature changes, which will only affect the aesthetics of the surface, and generally will not involve safety, so don't worry about the ceiling falling or something. How can this be remedied? It is recommended that you paste a layer of seam paper on the top, and the seam paper is painted with white latex, and then the putty is applied and then the top coat is brushed, if the gap is too large, then the crack is filled with plaster, and then the white latex is coated with the seam paper and then pasted, and then the putty is painted and painted.

3. There is also a situation that has something to do with the construction, because of the improper construction so the cracking is caused, if you encounter this situation, you must first check the keel of the ceiling, see if it is the quality of the base, and then check the appearance of the problem. If this is the case, if the ceiling is seriously deformed or damaged, it may have to be removed first, and then the keel will be leveled before proceeding to the next step! Generally, it is recommended not to open the windows after making latex paint, because latex paint is affected by humidity and temperature, and the unstable temperature difference between indoor and outdoor can easily lead to cracks in latex paint.

Of course, the decoration of the ceiling must be prevented, rather than remedied, and should be cautious when selecting materials for construction.

4. Selection of ceiling skeleton material.

When selecting light steel keel skeleton materials, strictly according to the design requirements and national standards of light steel, pay attention to the moisture content when selecting wood as keel, and the specifications and models of the keel should be strictly screened and should not be too small.

5. Ceiling finishing gypsum board selection.

At present, the gypsum board on the market has a variety of ordinary type, waterproof type, fireproof type, high-strength guessing and so on, in the design of the ceiling, it can be selected according to different use requirements, different regions and construction seasons. Now the quality of gypsum board in the decoration market is uneven, and the use of gypsum board with good quality produced by large manufacturers should be selected, with high strength, good toughness, uniform foaming, full edge molding, and solving the problem of cracks from the material.

In addition, there are generally two varieties of gypsum board with a thickness of 9mm and a thickness of 12mm on the market. Many people like to use 9mm thick ordinary gypsum board to make ceilings, but because the thickness of 9mm ordinary gypsum board is relatively thin, the strength is not high, and it is easy to deform under rainy and humid conditions, it is recommended that it is best to use gypsum board above 12mm. At the same time, the use of thicker plates is also an effective means of preventing joint cracking.

If there are cracks on the surface of the paint layer and guess the surface of the ceiling, it is generally caused by the paint layer being too thick or too dry, so the surface of the paint layer should be removed first, and then the new primer should be brushed on.

If the ceiling is cracked, it may be caused by the aging of the building, temperature changes, leaking water pipes, etc. Here are some of the things you can do:

1.Check and fix water leaks: If a crack in the ceiling is due to a leaking water pipe, the leak needs to be checked and repaired in time to avoid further damage.

2.Temporarily fix the ceiling: If the cracking is not too severe, you can temporarily use nails or adhesive strips to hold the ceiling in place to prevent it from continuing to rot and fall off.

3.Reinstall the ceiling: If the cracking is more severe, you can consider reinstalling the ceiling, which needs to be operated by a professional renovation company or worker.

4.Regular inspection: In order to avoid similar problems from happening again, it is recommended that you check the condition of the ceiling regularly and deal with it in time if any problems are found. In addition, it is recommended not to place heavy objects on the ceiling, so as not to cause pressure lifting pin force to the ceiling.

1.Use temporary patches: Some temporary patches can be used to temporarily repair cracks. For example, use some dental glue or temporary repair agent to fill the cracks, and after the glue or repair agent is dry, the leather shirt can be used normally.

2.Cut off the cracked part: If the cracked part is smaller, you can use scissors to cut off the cracked part. If the cut part is larger, you can consider making a new top.

3.Repair the other roof: If the cracked part is relatively large, you can also consider finding a professional dentist to repair the other roof. The dentist can use some professional materials to repair the cracked part, and the repaired top can restore the original use effect.

No matter which method is adopted, the key to dealing with cracking and other top is to deal with it in time to prevent the cracked lead holding part from expanding and affecting the use effect. At the same time, in the usual use, it is also necessary to pay attention to the care and maintenance of the other roof, and regularly go to the dentist for inspection and cleaning to prolong the service life of the other roof.

First of all, analyze the original cause of cracks, and formulate a corresponding plan according to this reason

Cracks on the paint film: Remove the affected paint film and repaint it according to the specifications.

Cracking caused by temperature changes: apply a layer of kraft paper and then brush the finishing coating; If the gap is large, you can cut a piece of drywall of the right size, fill it in the gap, and finally paint it.

If there is a problem with the ceiling keel or drywall: deal with the base layer first, and then paint the material. 4. If there is a problem with the front bone or gypsum board of the ceiling dragon cave, you need to deal with the grassroots problem first, and then paint the material.

If you have cracks in your hanging oak roof, here are a few steps you can consider:

1.Check if other parts are also damaged: If only a small part of the Mega is cracked, you can fix it and make sure there are no other parts that are defective.

2.Confirm the cause: It is important to determine the cause of the crack in the ceiling so that it can prevent similar problems from occurring in the future. Possible causes include water damage, wind tremors, and many more.

3.Arrange for repairs: Depending on the cause you find, your family pants may need to be repaired by a professional.

Keep in mind that if you're not sure how to deal with a crack in your suspended ceiling, it's best to consult a professional so that things don't get worse.

In this case, you must find a professional who is engaged in decoration to do it, what else can I do.

The reason for the cracks in the ceiling may be the reason for the shrinkage of the putty, or it may be that the keel made of wood is too heavy and there are loose parts, or it may be that the density of the boom is not enough to collapse, and the keel sinking and the adjacent keel have a slight dislocation.

1. Caused by temperature changes.

Paste a layer of seam paper on the top, the seam paper is painted with white latex, and then the putty is applied and then the top coat is brushed, if the gap in that piece is too large, then the crack is filled with plaster, and then the white latex is coated with the seam paper and then pasted, and then the putty is brushed and painted.

Second, there is a problem with the keel.

First fix the keel, add the suspension bar, and then buy the mesh cloth or grid belt, the general paint shop has to buy, directly scrape the putty on the original bottom, paste the mesh cloth, and then scrape, scrape the smooth and then paint, repair with the original is the same.

3. Cracking caused by improper construction.

If you encounter this situation, you must first check the keel of the ceiling to see if it is a quality problem of the base layer, and then check the appearance of the problem. If this is the case, the ceiling is seriously deformed or damaged, it may be removed first, and then the keel is leveled before the next step, the general family does not open the window after the latex paint, because the latex paint is affected by humidity and temperature, and the temperature difference between indoor and outdoor is easy to lead to latex paint cracks.

Fourth, the substrate is too rough.

In this case, the film should be removed and a new primer should be reapplied, always making sure that the primer is completely dry before applying it again, and not if the temperature is below 5 degrees Celsius.

Fifth, the problem of paint layer.

It is also the most common situation in home improvement, and the visible surface of the ceiling has a linear curved stripe. In this case, the main reason is that the surface is too heavy, at this time, you need to remove the previous paint film, and then apply a new layer of paint film, and brush the surface with paint after application.

1. The ceiling at home is generally a gypsum board ceiling. Some use wooden keel, some use light steel keel, for stability and durability considerations, it is generally better to choose light steel keel ceiling.

Second, it is not advisable to replace the keel by yourself, and after finding the problem, of course, you should contact the previous decoration company, let them replace the new one and be responsible for it.

1. The surface layer of the paint surface is cracked. If it is only the formation of linear, angular or amorphous cracks on the ceiling paint film, it is not a big problem. This phenomenon may be caused by the first time, such as too thick or not dry and heavy, too loose or rough base, and mismatch between primer and topcoat.

Remediation solution: remove the affected paint film; The paint film should not be too thick at one time; Make sure the front coat is dry before reapplying; Seal the substrate with a suitable primer if necessary; For substrates with high roughness, use products with good flexibility; When the substrate temperature is lower than 5, the latex paint cannot be constructed; The primer and topcoat should be matched.

2. Cracking caused by temperature changes. Because of the cracking caused by temperature changes, it is generally not a big problem, only affecting the surface, and will not involve the safety of the chandelier.

Repair plan: the gap is not large, it is recommended to paste a layer of kraft paper and then brush the finishing coating; If the gap is too large, it is best to cut out a piece of drywall first, polish it into a suitable shape, fill in the gap, and then brush the finishing paint.

3. Cracking caused by improper construction. Check the keel first, and then check the finishing material after dealing with the quality of the base layer. If the chandelier is seriously deformed and damaged, the demolition area can be expanded, and the keel can be repaired according to the normal construction steps after leveling.

Precautions: 1. It is best to use stainless steel drywall nails to fix the gypsum board, so that the nails will not rust, and the beauty of the gypsum board can be guaranteed for a long time in the future.

2. The nail hole on the gypsum board is usually treated with anti-rust nail hole putty.

3. The gap between the two gypsum boards should be dealt with well to avoid obvious cracks in the future. Generally, workers will use 901 glue and gypsum powder mixed to fill the joint.

4. After filling the gap with gypsum powder, it is best to paste anti-crack tape on the surface to prevent cracking of the top surface caused by thermal expansion and cold contraction. Pay attention to remove air bubbles and make the tape and drywall completely and tightly combined.

5. For the ceiling with special shape, the later treatment is very important. Suspended ceilings such as round and wavy need to be repaired slowly.

There are many reasons for the cracking of suspended ceilings, such as carpentry

1. The ceiling keel is made of wood.

The keel is still a light steel keel, and the wooden keel is more prone to deformation, or the stress is uneven during construction. Cracking is more likely to occur in the later stages.

2. Process problems: whether the whole corner of the gypsum board is used for sealing the gypsum board, rather than splicing (the cost has a certain relationship).

3. Painter: whether there is a strengthened anti-crack treatment to prevent it, and whether there is a caulking paper tape to strengthen the anti-cracking.

4. In the later stage of ventilation, large windows should not be opened for large-intensity ventilation, and the soft breeze effect of small windows is better, which can better avoid such problems.

Suggestion: Do a good job of carpentry foundation, smooth base and uniform stress, woodworking board priming, double-layer gypsum board cover (the cost will increase a lot), which can effectively prevent such problems.

Remedy: The cracking of the ceiling coating is more difficult to deal with after it is done, and it will leave obvious repair marks. It can be handled in the following way:

If it is only a slight crack, cut the V-shaped gap at the crack and clean it, and then use gypsum putty to fill the compact, sand, and paint. If the crack is large and obvious, it is necessary to shovel off about 10 minutes on both sides of the crack until the plasterboard is exposed and cleaned, re-mend the joint, apply the caulking tape, scrape putty, and paint.
