If not dealt with in time, it will not only affect family life, but may also lead to bigger problems, such as water leakage to the residents downstairs and property damage. Therefore, it is very important to master the method of waterproofing and repairing leaks on the roof. The following will introduce some common methods of waterproofing and repairing leaks on roofs.
1. Partial repair.
If there are cracks, water seepage and other damage to the roof, local repair methods can be used. The specific steps are as follows:
1.Cleanup: Remove dust, debris and loose concrete from the roof surface.
2.Caulking: Use waterproof mortar or sealant to fill the cracks to ensure that the caulking material is firmly bonded to the roof surface.
3.Apply waterproof paint: Apply waterproof paint twice to the caulking to ensure that the coating is evenly applied and no omissions are missed.
4.Surface treatment: polish and dry the roof surface to make the surface smooth, dry and oil-free.
2. Overall renovation.
If there is extensive damage to the roof, or if local repairs do not solve the leakage problem, a complete renovation is required. The specific steps are as follows:
1.Cleaning: Clean all the roof surfaces to ensure that the surface is smooth, dry and free of oil stains.
2.Waterproofing: Apply waterproof paint to the roof surface to ensure that the coating is evenly and without omission. The waterproof layer needs to be painted more than twice, and each application needs to be applied at intervals to allow the waterproof layer to dry sufficiently.
3.Laying waterproofing membrane: Laying waterproofing membrane on the surface of the waterproof layer to ensure that the membrane is firmly bonded with the waterproof layer. The waterproofing membrane needs to be laid in more than two layers, and each layer of membrane needs to be bonded by hot melting.
4.Concrete protective layer: Pour a concrete protective layer on the surface of the waterproofing membrane to prevent the roof surface from being damaged by external factors. The protective layer needs to be vibrated and compacted with a vibrator to ensure that there are no bubbles and no cavities.
5.Finishing work: polish and dry the surface of the roof to make the surface smooth, dry and free of oil stains. Finally, apply the waterproof paint again to ensure that the overall waterproofing effect is good.
The above are two common methods of waterproofing and leakage repair on the roof, and the specific method needs to be determined according to the actual situation. When repairing the waterproof leakage on the roof, the following points need to be noted:
1.Before construction, the roof surface needs to be treated to ensure that the surface is smooth, dry and free of oil stains.
2.It is necessary to choose a suitable waterproofing coating or waterproofing membrane and use it correctly according to the instructions.
3.During the construction process, it is necessary to pay attention to safety, such as wearing a helmet and fastening a seat belt.
4.During the construction process, it is necessary to maintain good ventilation to avoid toxic gases causing harm to the body of construction personnel.
