The parts of the prepainted steel roofing sheet that are prone to leakage are systematically waterproofed. These parts are mainly: color-coated corrugated board screw holes, color-coated corrugated board lap joints, etc. Color-coated corrugated board roofs are subject to the environmental climate for a long time, and the nail holes and joints will be worn for a long time, resulting in damage to the prepainted steel roofing sheet. The waterproof repair method of color-coated corrugated board can use metal roof waterproof coating with polyester cloth or self-adhesive waterproof membrane construction to seal all the parts of the color-coated corrugated board that may see water.
The rainy summer prepainted steel roofing sheet is soaked in rain for a long time, coupled with the acid-alkali corrosion of industrial discharge in industrial areas, it will be rusted and leaked at light, and the whole color-coated corrugated board will fall off. Thus affecting the normal operation. Therefore, the waterproof repair and maintenance work of color-coated corrugated board is very important in extending the service life of color-coated corrugated board. The line surface will take everyone to briefly understand the main reasons for the water leakage of the color coated corrugated board roof, and set the waterproof repair method of the color coated corrugated board according to the reason.
The parts of the prepainted steel roofing sheet that are prone to leakage are systematically waterproofed. These parts are mainly: the screw holes of the color-coated corrugated board and the lap joints of the color-coated corrugated board. Color-coated corrugated board roofs are affected by the environmental climate for a long time, and the nail holes and joints will be worn for a long time to cause damage to the color-coated corrugated board, and repeated cycles will cause serious water leakage.
The waterproof repair method of prepainted steel roofing sheet can use metal roof waterproof coating with polyester cloth or self-adhesive waterproof membrane construction to seal all the parts of the color-coated corrugated board that may see water. The metal roof waterproof coating is made of pure acrylic. It has the characteristics of sun protection, fast heat dissipation and can protect the waterproof layer. It can also be firmly pasted on the roof according to the height of the color-coated corrugated board, which can completely isolate the color-coated corrugated board from the air to achieve waterproof and Anti-corrosion effect. The waterproof repair method of color-coated corrugated board can also adopt cold construction technology, without open flame construction.
In addition, if the prepainted steel roofing sheet is waterproofed, the waterproof surface is generally increased, and the lap joints and bolts of the color-coated corrugated board are also waterproofed. The quality of color-coated corrugated board must be selected well, and the coating must be kept uniform during coating construction. Therefore, it is very important to prevent water leakage of roof prepainted steel roofing sheet. It is recommended that you take effective measures to deal with the problem.
