First, a small coup to repair the leaking ceiling
1, minor water leakage repair
If the ceiling is only slightly leaking and there is no obvious crack, then you don't need to knock off the original cement, just coat the surface with waterproof paint. If cracks can be seen on the ceiling, it is necessary to clean them up first, then plug them with cement, then apply waterproof agent, and finally wait for them to dry naturally.
2. Repair of serious water leakage
If the ceiling leaks seriously, we must first find out the approximate scope of the leakage and see if there are cracks on the roof countertop. Then, knock off a layer of cement on the ceiling with an electric drill; Then, apply a new layer of cement on its surface; Finally, apply waterproof paint.
3. Repair local water leakage
If only the ceiling leaks locally, it will be relatively simple to repair, just brush a layer of waterproof agent or asphalt on the seepage surface. If there are obvious cracks in the ceiling, first remove the cement on the surface of the ceiling, find the leaking brick joints, clean up the sediment in the cracks, then fill them with new cement, brush the waterproof coating again, and finally coat a layer of cement.
4. Repair of large area water leakage
If the ceiling leaks in a large area, it is likely that the waterproof layer of the floor has been destroyed. Encounter this kind of problem, can only do a waterproof layer on the ceiling. Because it involves a large area and requires high professionalism in construction, it is best to ask a professional construction team to handle it.
Second, how much does it cost to repair the leaking ceiling?
1, the cost of repairing the leakage of ceiling is mainly composed of two parts: material cost and labor cost. There are several kinds of materials, and the prices of them are naturally different because of the different types of materials used for trapping. Under normal circumstances, the repair project of leaking ceiling is to choose contracted materials. If it's an ordinary leak-trapping material, the cost per square meter is about 40-60 yuan.
2. The cost of repairing the leakage of the ceiling will be different due to the different prices of the leakage patching materials. Among them, the cost of leak-trapping materials accounts for about 65% of the total cost, and the labor cost accounts for about 35% of the total cost. In other words, the labor cost for repairing the leaking ceiling is about 22- 1 m2 in 32 yuan.
Summary: The maintenance cost of ceiling leakage is to add up the material cost and labor cost, and the cost per square meter is about 62-92 yuan.
