Some houses will leak when the roof is used for a long time. Leakage on the roof is a big problem. Not only does it make the walls of the room moldy, but if the wallpaper is attached to the room, the wallpaper will fall off, so leaking the roof will cause great trouble and inconvenience to our lives. So what are the best methods for roof leaks ? What should I pay attention to when making roof leaks? Let's take a look with the editor.
1. The best method for roof leakage repair
1. Filling gaps: In general, roof leaks are caused by cracks, so when the roof is leaking, first fill its gaps. Apply a layer of waterproof paint after the filled area is dry, but this is only suitable for small gaps.
2. Waterproof coating: Waterproof coating is a relatively common type of roof leak repair. First, use waterproof coating to brush the water leak twice, the length must be more than 20 cm. This can not only ensure its adhesion, but also ensure its service life, but it should be noted that it can not be rained within 12 hours after painting.
3. Waterproof membrane: The best method for roof leakage repair can also use sbs waterproof membrane, but use good quality waterproof membrane, such as waterproof membrane made of polyester tires. This kind of waterproofing not only has good leakage repair effect, but also its price is relatively affordable.
4. Pouring concrete: If a large area of ​​the roof leaks, then a layer of concrete can be laid on the roof. At the same time, you can also lay the concrete after the sbs waterproof coiled material. First, use a steel bar to make a layer of mesh on the roof, and then use the concrete to solidify the top. However, it needs to be cured for half a month after construction, such as watering or Cover things for protection.
Second, what should pay attention to roof trap
1. Before leak repairing, the roof must be cleaned first, such as some sand, dust, etc. must be cleaned. If the surface of the roof has a high and low span, then the construction method of its waterproof layer should be from high to low, or advanced and remote construction.
2. When applying the waterproof layer, the construction must be done after its surface is dry. For example, use a square of waterproof membrane to level the roof, and check it after standing for 3 to 4 hours. If the roof covered with waterproof membrane does not have a watermark, it can be constructed.
3. If it is a large-area leak-retaining coating film, it should be strengthened in its water outlet, gutter and other places. Secondly, the thickness of the coating waterproof layer should be designed reasonably, and the phenomenon of bulging, cracks, etc. should not occur.
Editor's summary: The best method and precautions for roof leaks are introduced here. When constructing the roof, block the sewer opening and then wrap it up, so that the cement and sand will not block the pipeline during the construction process, which is convenient for daily life in the future.
