What should we do if the color steel plate house leaks? Especially in the rainy season, if there is rain leakage, let's take you to know how to deal with it.
(1) Exposed waterproof layer:
Waterproof coiled materials and cold bonding method shall be used for construction, and SBS hot melt construction shall not be used. It will damage the thermal insulation layer and reduce the service life of color steel plate. It is recommended to use EPDM waterproof coiled materials, which have strong ultraviolet resistance and can not damage the thermal insulation layer during cold processing. It is a rare waterproof material.
(2) The waterproof layer is not exposed:
Acrylic waterproof coating (JS composite coating or acrylic waterproof coating) can be used for repair. This material has good weather resistance and is not easy to age.
Why does the color steel plate roof leak?
1. It may be the color steel plate deformation caused by transportation, or it may be the color steel plate deformation caused by people during construction due to poor quality of the color steel plate.
2. Force majeure factors, such as strong wind will cause the color steel plate roof to vibrate for a long time, making the bolts for fixing the plates worn. In addition, rain erosion will lead to rust and rain leakage over a long period of time.
3. The self tapping screw with its own rubber ring will also leak?
1： It may be that the rubber ring is damaged by excessive force during construction.
2： After a long time, the rubber ring will age and lose its waterproof effect.
4. The roof span is large, and it is easy to cause ponding on the roof for a long time. If the ponding is serious, it can lead to serious deformation of the roof color steel plate due to the increase of gravity, and even cause roof collapse.
5. The corners of roofs with different heights are easy to seep water, so the splayed corners can be plastered with cement, sealant or waterproof coating can be used for waterproof protection.
6. When using weather resistant sealant, pay attention to whether it will crack after solidification, and be sure to clean the wall dust before construction.
7. Why does the waterproof coating leak after two years of repair? The fluidity of waterproof coating causes uneven coating thickness during construction, and cracks are not easy to be found. In addition to the vibration of the roof, the elongation of the coating is low and cracks appear. The construction of waterproof coating is jerry built. If the coating thickness is too thin, it will quickly age and crack.
The above points basically introduced the common phenomenon of water leakage on the roof of color steel plate and the treatment methods. I hope it can help the friends who are still troubled by it.
