Using color steel coiled plate as building material mainly has the advantages of short construction period, low foundation requirements and convenient use. Of course, it will also have shortcomings. The main problem is that there is leakage at the roof,
rivets and slab joints, which affects the normal use. However, the small problems existing in these color steel coils will always be solved. After research, test and construction, relevant experts have summarized some effective maintenance methods
for water seepage of large color steel sheet roof.
1、 Repair method of water leakage at rivet:
Apply sunshine one component waterproof adhesive for 4 times, with a thickness of about 1.5 and a diameter of about 50-60mm. The next time, the above coating shall not stick to hands, and the diameter
of each coating shall be larger than that of the first coating, which is thick in the middle and thin in the circumference. So the rivets won't leak
2、 Rain leakage method of color steel plate joint:
1. One component waterproof glue with width
of 60 × 2000Pa can be applied at both ends of the joint, and it is not applied near the joint for 20.
2. Non woven fabric (or glass fiber cloth), 150 wide, pasted on sunshine 2000Pa waterproof adhesive.
3. The non-woven fabric or glass fiber
cloth shall be painted for 3 times, and the latter one shall be 50 wider and about 1.8 thicker than the previous one. The last painting shall be subject to the non stick of the previous coating.
Pay attention to some details. Generally speaking,
color steel plate will not have much problems, so color steel plate is a Zui good building material in building materials. Similarly, the market of color steel plate will develop better and faster.
