Ceiling decoration common problems and solutions
Ceiling design plays a crucial role in home decoration. A well-designed ceiling not only enhances the overall aesthetics of your space but also contributes to a more comfortable and functional living environment. However, during the process of ceiling decoration, various issues may arise that can affect both the appearance and safety of the space. Today, we will discuss some common problems and provide detailed solutions to help you avoid potential risks.
One of the most serious issues is the collapse of painted flat ceilings. In some cases, this has led to damage to the interior, and even injuries. The main reasons behind this problem include:
1. The base of the floor is uneven, leading to an excessively thick leveling layer or contamination on the board's surface.
2. The formwork for cast-in-place concrete slabs was improperly installed, resulting in unevenness or using waste engine oil as a release agent. Additionally, materials like fiberboard were used to fill gaps without proper cleaning before painting.
These conditions can lead to poor adhesion between the stucco layer and the slab, causing hollow drums or cracks. If not addressed during renovation, the leveling paint may be directly embedded, and vibrations from tools like impact drills can eventually cause the ceiling to collapse.
To prevent this, it’s essential to inspect the existing plaster layer thoroughly before starting any work. Any loose or cracked areas should be removed and re-done. When using high-vibration tools, care must be taken to avoid damaging the repair layer until it is fully bonded. Some authorities are now considering eliminating prefabricated slabs in residential buildings and instead using cast-in-place concrete slabs with a properly leveled bottom surface. This approach helps reduce the risk of ceiling collapse.
When painting a flat ceiling, it's important to check whether the paint layer is firmly attached, free of hollow spots, and crack-free. You can do this by visual inspection and tapping the surface.
Another common issue is the collapse of suspended ceilings. This can result in serious accidents. The causes of such collapses include:
1. "Hanging from the sky": This involves fixing the boom to the ceiling using nails, screws, or steam nails. Sometimes, wooden materials are nailed directly into the concrete slab.
2. "Supporting from the side": Instead of suspending the ceiling with a boom, the keel is fixed to the wall or beam using nails.
3. Overloading the boom: If the boom is too thin or spaced too far apart, it may not support the weight of the ceiling.
4. Poor quality materials: Wooden booms that split or nails that are too short or insufficient in number can also lead to failure.
In many cases, the ceiling appears fine immediately after installation, but over time, the nails may loosen due to friction or movement, causing the ceiling to sag or collapse. This can happen especially if there are no supports in the middle of the keel, or if the structure is not properly reinforced.
To avoid these issues, it's crucial to ensure that all components are correctly installed and that the structure is strong enough to support the weight. Regular inspections and proper maintenance can also help extend the life of your ceiling and keep your home safe.
