Possible causes of wall cracking:

1. There are cracks in the insulation layer of the original house, which leads to cracking of the wall after decoration;

2. Improper repair and painting after the wall is slotted, resulting in cracks in the wall shrinkage;

3. The ratio of cement is inaccurate when plastering, and it is easy to crack if the ratio is high;

4. The situation is that the ratio of wall putty is improper or uneven scraping.

5. The ratio of latex paint and water is not suitable, and the above non-standard operations will lead to cracking of the wall.

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

1. Whether the ceiling keel is a wooden keel or a light steel keel, 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.

Repair: The cracking of the ceiling coating is more difficult to deal with after it is done, and it will leave more 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 cm on both sides of the crack until the gypsum board is exposed and cleaned, re-mend the joint, apply caulking tape, scrape putty, and paint.

Cracking of the ceiling should refer to the cracking of gypsum board. In this case, there is no need to remove it, directly remove the latex paint and putty around the crack, and then apply a bandage and smear putty, so that the cracked gypsum board is connected together. Then re-batch putty, sanding, leveling, and finally brush latex paint.

Hope it helps!

It can only be said that the quality of the decoration construction of the landlord is very poor, and it is estimated that he has found the wrong decoration company.

Reasons for ceiling cracking: 1. The flatness of the top and wall is not enough, when we fix the keel upward, it is more energetic, so let the oiler first carry out gypsum leveling on the wall on the spot, first find out the flatness of the wall and the top surface, and then hit the keel after leveling, which can effectively reduce the cracking of the ceiling; 2.The keel used is a wooden keel, which will be deformed with the change of temperature and humidity, and once the wooden keel is deformed, the thin gypsum board outside will also crack; 3.

Cracking in the corner, or at the seam, so the corner must be made of the whole board, do not have a seam in the middle, there are seams left to the two ends, the seams should also be done deep V-shaped treatment, filled with caulk, scrape putty outside, then paste mesh cloth and kraft paper, scrape putty and paint, can effectively reduce cracking.

Cracks in the walls and ceilings are inevitable in the decoration of new houses, and there are many reasons for this, and the remedy is to scrape putty and brush latex paint from the new adhesive joints.
