In daily life, we often find that the roof is leaking.

Then what are the best methods for trapping the roof and what should you watch out for on the roof? Learn with Xiaobian!
The best method for trapping roof
1, fill in the gap
Most leaks on the roof are caused by cracks, so when filling leaks, it is necessary to fill gaps with trapping paste first, and then apply waterproof paint after drying. If the gap is small, paint can be applied directly.
2, waterproof coating
Waterproof coating is commonly used as a material for roof trapping. Water-based waterproof coating is first brushed on the gap twice, and the minimum must be more than 20cm. In order to ensure the sticking force and ensure the long service life, it is also necessary to take care that no rain can be found within 12 hours.
3, waterproof membrane
Sbs waterproofing membranes can also be used to make up for leaks on the roof. You can use better quality ones, such as polyester waterproof membranes, which have good waterproof effect and are inexpensive.
4. Rural roof
If it is a leak on the roof of a rural area, it is recommended that cf-2000 high-efficiency composite water repellent be used for repair because of its environmental friendliness, long service life, and affordable price. Most of the roofs in rural areas are used for drying food. Never use asphalt to repair the asphalt. Asphalt has a strong carcinogenic effect. If it seeps through the grain, it will harm the human body.
5, pouring concrete
If the roof is leaking, you can also directly pour a layer of concrete directly on the roof, or you can put a layer of concrete directly on the roof after you finish the waterproofing membrane. The specific approach is: First, use fine steel bars to be laid on the roof to form a net, and then use a pump truck to pour the concrete on it. After the water is poured, it needs to be maintained for about half a month, covering the surface with a cover.
What should you watch out for on the roof?
1. Before construction, dust, sand, gravel, and other debris on the surface of the grassroots should be removed first. If the surface has high and low spans, the construction of the waterproof layer should be constructed according to the principles of high first, low first and first, second and later.
2, coating waterproof layer, you must first detect the dryness of the base surface, the test will be 1 square meters of waterproofing membrane flat laying on the leveling layer, set aside for 3-4 h after open inspection, leveling layer cover and waterproof The coil can be constructed without a watermark.
3. If it is a large-area coating construction, additional enhancements should be made to water-falling, gutters, and cornices. The thickness of the coating waterproof layer must also meet the design requirements, and there must be no cracks, wrinkles, blisters, etc.
