How to use half water gypsum to make ceiling cracks
In addition, the paper gypsum board market generally has a thickness of 9mm and thickness of 12mm two varieties. Many people like to use thick 9mm ordinary gypsum board to do the ceiling, but because the thickness of 9mm ordinary paper gypsum board is relatively thin, the intensity is not high, prone to deformation in the rainy wet conditions, it is recommended to use more than 12mm gypsum board. At the same time, the use of thicker plates is also an effective means of preventing joint cracking
Currently on the market of gypsum board with ordinary type, waterproof type, fire type, high strength and so on, in the ceiling design, according to different requirements, different regions and construction season selection. Now the decorative market gypsum board in the quality of good ouchy, the use of large manufacturers should use the quality of the production of better quality gypsum board, high strength, good toughness, uniform foam, edge forming full, from the material to solve the cracks problem.
When the ceiling foundation works are completed, there may be other work processes. If the convergence of work is not coordinated, chaotic operations, mutual interference, after the process of brutal construction, it is more likely to cause ceiling cracking. Such as open the lamp hole, there is no protective measures, causing the ceiling vibration, which led to cracks appear. In addition to the daily maintenance of the repair after the repair of the ceiling inside the pipeline, equipment, if there is no standard operation, it is easy to cause keel deformation or finishes damaged, making the ceiling cracking.
Gypsum board ceiling cracking repair will crack.
In the installation of gypsum board, if there is no installation specifications from the middle to the four sides of the screw, but from the four sides at the same time on the screw, then the gypsum board will produce stress, if the stress is large enough, will cause cracking; Gypsum board screw spacing is too large or some screw position, although correct, but if not fastened, will lead to cracking.
