What should I do if there is a seam in the plaster line of the ceiling?

It should be that the decoration material is relatively poor, find a good master to take a look, but it is best not to look for the original help you do, the technology is not up to par. Next time I change to AIA integrated ceiling, I use it, there is no such situation, don't worry about cracking.

When installing a suspended ceiling, you need to do everything to avoid cracks. How is the plaster ceiling caused by cracks? PChouse will take you to find out.

1. How to cause the joints in the gypsum ceiling, the volume stability of the gypsum board ceiling, because the gypsum used in industry is formed by heating gypsum dihydrate and discharging crystal water. Gypsum board is processed and shaped, and water is added to the burned and ground semi-hydrated gypsum to form the important characteristics of the gypsum dihydrate structure. The needle-felt crystals are separated from the gypsum slurry and dried to form micropores, so that the processed gypsum has the property of "breathing", and even when the air humidity changes, it can absorb moisture and quickly re-emit it.

2. The influence of the strength of the gypsum board ceiling, the structure of the gypsum board is firmly bonded together with the gypsum core and the protective paper, the protective paper can withstand the tensile force and reinforcement, and the protective paper layer has a very important impact on the bad board. The strength and elasticity of the longitudinal and horizontal bidirectional fibers of the face paper are different, the longitudinal is larger than the transverse, and the longitudinal bending and deformation resistance is also stronger.

Gypsum board has strong resistance to moisture, and the paper surface layer can prolong the time for the board to absorb water, but it cannot prevent water absorption. During the installation and construction process, if it is soaked by moisture for a long time or continuously, the strength of the gypsum board will be reduced. Therefore, it is important not to install wet panels.

High temperatures can affect the strength of gypsum board. When the ambient temperature of the gypsum reaches 42°, the solidified gypsum will begin to change the crystalline structure, causing damage to the strength, so the gypsum board cannot be directly connected to the heater, etc.

The problem of gaps in gypsum board ceilings and walls is widespread, mainly due to improper construction. The presence of gaps not only affects the decorative effect, but also causes problems such as water leakage. Therefore, it is very important to address this issue in a timely manner.

Here are some solutions that I hope will help you.

1. Repaint the plasterboard.

For plasterboard ceilings and walls that have already been installed, the easiest solution is to repaint the plasterboard. First, use gypsum board powder mixed with water to make gypsum socks orange paste, fill in the gaps, and use a flat scraper to smooth and let it dry. Then sandpaper is sanded, and finally a coat of paint or wallpaper is sufficient.

Second, use gypsum board seam tape.

If the gap is large, you can use drywall seam tape to reinforce. Start by filling the gap with the same method and attaching the seam tape to the gap. The joints are then filled with plasterboard powder and allowed to dry. Finally, paint or wallpaper can be applied as well.

3. Replace the gypsum board.

For large or large gaps, drywall may need to be replaced. It is necessary to pay attention to the size of the replacement to ensure that the new plasterboard is consistent with the original size and shape. In addition, it is also necessary to pay attention to the problem of joint position, so that the joint position of the old and new plasterboard will not overlap, so as not to affect the decorative effect.

In short, the key to solving the gap problem of gypsum board ceiling wall lies in the construction process. Before construction, it is necessary to make corresponding preparations, and strictly control the quality during the construction process to ensure that the construction is in place to avoid the occurrence of gap problems. If a gap already exists, it is important to take action as soon as possible to avoid causing more problems.

Gypsum board ceiling, plaster lines are pasted in the corners, and what is the reason why there are cracks in the gypsum lines.

Kiss Gypsum lines may cause cracks due to factors such as improper construction, temperature changes or shrinkage of building materials during installation, and the possible reasons are as follows:1The quality of the plaster line itself:

If the material or manufacturing process of the plaster line is insufficient, it will affect its quality and accelerate aging and cracking. 2.The effects of temperature and humidity are buried

The temperature and humidity in the environment can affect the shrinkage and expansion of the plaster lines. If the temperature and humidity in the environment change drastically, the plaster lines may be affected, leading to cracking. 3.

Settlement of the building: In the process of building use, due to the continuous settlement of building materials, it may lead to the rupture of the plaster line. 4.

Non-standard construction: If the construction personnel do not operate in accordance with the standard and do not choose the appropriate special glue for fixing, it may cause cracking. If there are cracks in the plaster line, it should be repaired in time to prevent the cracks from expanding or causing safety problems.

Laying direction, fixed transversely and longitudinally.

The strength performance and deformation of gypsum board are determined according to the direction, and the longitudinal performance of the board is superior to the transverse, so the longitudinal part of the gypsum board is not allowed to be parallel to the covered keel when the ceiling is suspended, and it should be perpendicular to the keel, which is an important measure to prevent deformation and cracking of joints.

When installing the partition board, it should be laid longitudinally, because the longitudinal length of the board is the same or close to the height of the floor, and it has the advantage of fixing with the vertical keel, and the longitudinally laid joints are conducive to improving the fire protection capacity.
