>>>Link: Experts Analyze the ceiling installation process
There are two main problems that are easily seen in plasterboard ceilings:
The first situation is about half a year after the completion of the ceiling, cracks begin to appear at the joints of the gypsum board. The solution is to make sure that the gypsum board is fixed in the unstressed state when the plasterboard ceiling is in place. The distance between the keel and the fastening screw must be strictly in accordance with the design requirements; care should be taken in the overall scraping of the putty, and the putty should not be too thick.
The second case is the irregular wavy ceiling. The surrounding grille or square corners of the suspended ceiling, or the shrinkage caused by the large moisture content of the wood, can cause uneven crowning. In addition, the keel joint is uneven and has a hard bend. The distance between the hanger or the reinforcement tends to deform the spur keel, and it also causes the ceiling to be uneven. The top of the wooden boom is chapped and it is not tightened when the boom is made of steel, which can cause irregular wave deformation. The lighter steel keel is best used for ceiling projects with large area.
To prevent ceiling arching, the ceiling timber should be made of high-quality soft wood, its moisture content should be controlled within 12%, the keel should be straight, there must be no transverse section through the section, ceiling construction should be leveled on the wall around the wall, install The level is based on the four weeks.
