At the lap joint of the lower metal plate, then gently press the adhesive tape by hand to make it firmly adhere to the metal.
(4) Tear off the release paper on Yongxing adhesive tape, press the metal plate on the upper layer of the interface into the joint and stick it well.
Squeeze the joints in sequence, so that the joints are firmly combined and closed tightly.
(5) Fix and tighten the screws so that the upper and lower adhesive surfaces of the adhesive tape are closely adhered.
2, metal plate roof gutter construction method
(1) After the installation of precast gutter, clean the cement surface of parapet above gutter, and brush the basic treatment agent.
(2) After the treating agent at the grass-roots level is suspected to be solid, install the flashing board to ensure firm installation and close combination with the wall.
(3) Wipe the flashing board clean, stick a single-sided aluminum foil Yongxing adhesive tape at the joint between the flashing board and the cement wall, and press it in turn to make it firmly bonded;
If you use 80mm wide single-sided aluminum foil Yongxing adhesive tape, you don't need to use the flashing board.
3, steel roof leakage repair engineering construction method
The metal plate leaks due to contact.
(1) Clean the original sealant at the lap joint of the metal plate.
(2) Wipe the metal plate of the repaired part clean.
(3) Choose single-sided aluminum foil Yongxing adhesive tapes with different specifications according to the leaking joints;
(4) directly covering the joint with single-sided aluminum foil Yongxing adhesive tape;
(5) After bonding, the repaired parts are rolled up in turn, so that the single-sided aluminum foil Yongxing adhesive tape is firmly bonded at the joint.
The combination of profiled steel plate and cement wall is leaking.
(1) Clean all the original silicone adhesive at the joint between profiled steel plate and cement wall;
(2) Wipe the joint between the profiled steel plate and the cement wall clean; It is required that the cement wall shall not be sanded, including
Conditional should be coated with grass-roots treatment agent.
(3) The joint between the metal plate and the cement wall is bonded with single-sided aluminum foil Yongxing adhesive tape and then rolled and repaired in turn.
In addition, the single-sided aluminum foil Yongxing adhesive tape is firmly bonded at the joint.
