Butyl tape construction methods in different parts

Butyl tape is a waterproof material that we often use in our daily lives. Let us introduce to you how to use this waterproof tape and the construction method of this waterproof tape in different parts.

1. Construction method of butyl tape in new steel structure roof

The specifications and sizes of butyl tape should be selected according to the gap and joint width of the metal plate type or joint and the requirements of engineering design. Wipe the metal plate joint clean. Starting from the end of the metal plate, slowly open the butyl tape and stick the butyl tape in a straight line along the joint. At the overlap of the lower metal plate, press the tape gently by hand to make the butyl tape firmly bonded to the metal. Tear off the isolation paper on the butyl waterproof tape, press the metal plate on the upper layer of the interface into the joint, squeeze the joint in sequence after bonding, so that the joint is firmly bonded and tightly sealed, tighten the screws, and make the upper and lower bonding surfaces of the butyl tape tightly bonded.

2. The construction method of butyl tape on metal roof gutters

After the prefabricated gutters are installed, clean the cement surface of the parapet above the gutters and apply the base treatment agent. After the base treatment agent is cured, the flashing board should be installed to ensure that it is firmly installed and tightly connected to the wall. Wipe the flashing board clean, stick the single-sided aluminum foil butyl tape on the joint between the flashing board and the cement wall, and squeeze it to make the butyl tape firmly bonded. If single-sided aluminum foil butyl tape is used, the waterproof board can be omitted.

3. Construction method of using butyl tape to deal with steel structure roof leakage

The original sealant at the overlap of the metal plate should be processed after the overlap of the metal plate leaks, and then the metal plate at the repaired part should be wiped clean. According to the joint situation of the leaking part, choose single-sided aluminum foil butyl waterproof tape of different specifications, and directly cover the joint with single-sided aluminum plastic butyl waterproof tape. After bonding, the parts should be rolled to make the single-sided aluminum foil butyl waterproof tape firmly bonded at the joint.

4. Use butyl tape to treat leakage in the combination of corrugated steel plate and cement wall

Clean the original silicone water at the joint between the corrugated steel plate and the cement wall, and then wipe the joint between the corrugated steel plate and the cement wall. The cement wall should not be polished with sandpaper. If possible, a base treatment agent should be used. Stick the single-sided aluminum foil butyl tape on the joint between the metal plate and the cement wall, and then roll up the repaired part.

When using, please pay attention to firmly bond the butyl tape at the joints, check after completion to confirm that there are no problems with subsequent use, and regular maintenance is also important.
