Roof gutter:
Roof gutter refers to the concave part between the two legs of the building roof, which is generally called the drainage ditch on the roof. There are two main ways of roof drainage (mainly flat roofs). One is a roof with parapets, because rainwater is blocked by parapets and cannot flow out. At this time, organized drainage is generally adopted, that is, rainwater is collected in the gutter and then discharged through the drainage pipe. The other is unorganized drainage, which allows rainwater to flow down the roof naturally without any drainage measures.
Practice of gutter drainage:
You may not know much about this. Generally, if there is a problem, they will find a repairman to solve it. Sometimes the repairman simply repairs it, but it can't "cure the problem". Therefore, it is necessary to understand the practice of roof gutter waterproofing.
First, we must first eradicate the original waterproof layer. The reason why the roof leaks a lot is that the original waterproof layer has problems. In fact, the waterproof layer has a certain service life and needs to be replaced regularly, but often we only carry out maintenance when there are problems, which will often cause some economic losses.
Second, clean up the grassroots. When cleaning the base, all foreign bodies, dust and sundries on the surface of the base must be cleaned up, especially the internal corners, which need to be cleaned carefully. After cleaning the base, you can better paint a new waterproof layer. If it is not cleaned, it is likely that the new waterproof layer will be uneven, which is not worth the candle. So cleaning up the grassroots seems simple, but it is actually a very important step.
Third, brush the waterproof layer for the first time. When coating the waterproof layer, it should be uniform, and there should be no omissions. In the process of film coating, we should also pay attention to the fact that the wet coating can not be polluted, so that the waterproof layer can be used for a longer time.
Fourth, apply the waterproof layer for the second time. The method of daubing is the same as that of daubing the first layer. It should also be noted that water should not be splashed before the waterproof material is dry.
Fifth, acceptance. After the waterproof layer is completely dry, rinse it with clear water to see if it will leak.
After these five steps, the roof gutter waterproofing is completed. These seemingly insignificant little common sense are still very important when encountering difficulties!
