Plasterboard ceiling cracking can be caused by a variety of reasons, such as the settlement of the house, temperature changes, humidity, etc. If the crack is small and not noticeable, it can be repaired, but if the crack is large or there are multiple cracks, redaging is a better option.

The cost of redecorating a gypsumboard ceiling varies from region to region, generally speaking, according to the local market price, the ** range of decorating an ordinary-sized gypsumboard ceiling is between 1000-3000 yuan. The exact cost is also affected by the following factors:

1.The material and specifications of gypsum board: different materials and specifications of gypsum board**, generally speaking, better quality gypsum board** will be slightly higher.

2.Difficulty in the design and construction of the ceiling: If special design is required or the construction is difficult, the cost will increase accordingly.

3.Use of auxiliary materials and tools: The use of auxiliary materials and tools such as screws, glue, angle irons, etc., will also increase the cost.

4.Labor cost: Labor cost is an important part of decoration cost, and labor cost will vary according to local labor cost standards.

It should be noted that the above costs are for reference only, and the specific costs need to be estimated according to the actual situation.

The cost of renovating the gypsum board ceiling includes the cost of gypsum board materials, auxiliary materials, labor, etc. Among them, gypsum board material costs occupy a large proportion, generally speaking, gypsum board ** between 10-30 yuan square meters. The cost of auxiliary materials includes screws, glue, angle irons, etc., and the cost is calculated according to the actual amount used.

Labor costs are calculated according to local labor cost standards, and generally speaking, labor costs account for 30-50% of the total cost.

In short, if the plasterboard ceiling is cracked and the problem is serious, it is recommended to redecorate. The specific cost is estimated according to the local market price and the actual situation, including gypsum board material cost, auxiliary material cost and labor cost.

Personally, I think that if the gypsum board ceiling is always cracked, it needs to be redecorated at this time, because if you don't redecorate, you can't achieve a better effect at all.

The crack ceiling of the gypsum board can be repaired, if this always happens, then it is necessary to re-do it, otherwise this situation is also very dangerous, and it is not beautiful.

Depending on your personal needs, you can choose without redecorating. I don't think it's beautiful, as long as the part is trimmed, this can be set up with a stable ladder, and I can replenish the plaster at home.

Hello. Home expert Yingzi is happy to answer for you. Pro, 1, the keel is not stable enough to lead to cracking gypsum board ceiling in the erection of the keel, the flatness is not enough will lead to structural instability, the subsequent gypsum board overlay is difficult to fit perfectly, during the use of the uniform force will lead to deformation and cracking, this cracking problem is basically unable to lift the repair, the ceiling needs to be reinstalled to completely solve.

2. The junction of gypsum board and other materials is inconsistent with the expansion ratio, resulting in cracking The junction position of gypsum board and wall is easy to crack, because the expansion and contraction ratio of these two materials is different, in order to avoid this problem, gypsum board needs to be integrated from the bottom of the beam when installing, that is, the beam is wrapped in the ceiling, so as to avoid the problem of handover and cause cracking. 3. Improper treatment of gypsum board joints leads to cracking of two gypsum boards in splicing, if it is not handled properly, it is easy to crack, especially the expansion joints must be reserved, controlled at 3-5mm, noisy more than this width needs to use more plaster, easy to crack, and too narrow, there will be insufficient expansion distance, and cracking will also be cracked under expansion and extrusion. 4. Improper handling of the ceiling process leads to cracking gypsum chain boss ceiling during construction, there will be corners, and the corners are usually L-shaped, T-shaped, etc., the gypsum board in these positions is not suitable for splicing, and the whole board should be cut directly, otherwise there will be inconsistent stress balance and cracking.

If I can help you, you give a like, look forward to your like, dear, thank you.

Summary. Hello dear, gypsum board cracking 1, the keel is not stable enough, resulting in the cause of cracking: when the keel is completed, the flatness is not enough, the structure is unstable, resulting in the entire gypsum board overlay when it goes up, it is not naturally attached to the keel, but under the force of installing self-tapping screws, the gypsum board itself is distorted and deformed and attached to the keel.

Long-term stress imbalance leads to the final gypsum board deformation cracking, which causes cracking of the surface paint.

Hello dear, gypsum board cracking 1, the late cong keel skeleton is not stable enough, resulting in the cause of cracking: when the keel is completed, the flattening and disorder of the regularity is not enough, and the structure is unstable, resulting in the entire gypsum board overlay when it goes up, it is not naturally attached to the keel, but under the force of installing self-tapping screws, the gypsum board itself is distorted and deformed and attached to the keel. The long-term stress imbalance leads to the final deformation and cracking of the gypsum board, which leads to the cracking of the surface oil code cherry paint.

2. The junction of gypsum board and other materials is inconsistent, resulting in cracking reasons: the position of gypsum board and wall junction is usually two materials, especially when we weaken the beam through the gypsum source beam ceiling, the handover treatment between them is usually ignored, and the direct and beam bottom surface is flattened, close, and the treatment of the butt joint is not fine enough which crack is simple, and the bottom of the beam and gypsum board are two materials, the expansion ratio after heating and cooling is not consistent, therefore, Inconsistent shrinkage will naturally crack the putty and paint layers, leading to cracking.

Causes of cracks:

1.If the ceiling paint film produces linear, angular or amorphous cracks, then the problem is not very serious. This phenomenon may be caused by the fact that the substrate is too loose or rough after the first application or not dry and reapplied, and the primer does not match the topcoat.

The solution is to remove the affected paint film, the paint film should not be too thick at one time and ensure that the front layer of paint is dry before recoating, and the substrate must be sealed with a suitable primer.

2.Temperature changes cause cracking. If the cracking is caused by a temperature change, it usually only affects the surface and is not a big problem.

If the gap is not big, you can paste a layer of kraft paper and then brush the finishing paint, if the gap is relatively large, then it is best to cut out a piece of gypsum board, polish it into a suitable shape, fill the gap and then brush the finishing paint.

3.Cracking caused by improper construction, etc. If the cracking is caused by improper construction, the keel should be inspected first, and then the finishing material.

In the daily ceiling, the gypsum board ceiling is very widely used because of its many advantages, but the gypsum board ceiling will crack after a long time, why does the gypsum board ceiling crack?

The main reasons for the cracking of the gypsum board ceiling are as follows:

1. The influence of ceiling strength.

Gypsum board is a product of the combination of gypsum core and protective paper, and the protective paper bears the tensile force and plays a reinforcing role, so the protective paper layer has a great impact on the board, so it may be caused by the unstable pasting of the paper surface.

2. The influence of light steel keel.

The design and material quality of the light steel keel are also the key reasons for the cracking of the ceiling. As long as any place is not passed, it will cause problems for a long time, take the fixation between the light steel keel and the gypsum board on the paper as an example, if it is not according to the procedure and the fixation is not reliable, it will lead to internal force in the board, and the shear of the plate joint will lead to deformation and cracking.

3. The influence of caulking process.

When the keel and the gypsum board ceiling are stressed, the gap will be subjected to various pressures, which is why there are seams between the boards, and if the caulking material itself does not have enough adhesion and strength to support the pressure, it will lead to cracking.

4. The impact of improper construction.

Generally, before the caulking process is completed, the wallpaper paint is brushed, and the ceiling water and electricity installation is not completed, if the construction personnel step on the keel frame, it will cause the joints to crack, and even lead to deformation, which is one of the main reasons for the cracking of the gypsum board ceiling, and we must keep in mind.

1. Putty repair latex paint method. First use putty to fill the gap of the gypsum board ceiling, and then wait for the filler in the gap to dry, and then use a telescopic cloth to stick to the gap.

2. Pouring gypsum water filling method. First clean the plaster in the gap and expand the gap, and then use a vacuum cleaner to clean up the remaining small dust and other debris, then brush the gap, pour the mixture of thick gypsum and water, smooth the gap of the gypsum board, dry for 24 hours, and then use fine sandpaper to gently sand, and then brush the primer with a dry smile, and the gypsum board latex paint can be painted after the most traceless.
