What precautions should be taken when using sealed waterproof tape? Many users are not particularly familiar with it, so today the editor takes this opportunity to give you a detailed introduction. The precautions for using sealed waterproof tape are as follows:

(1) Before construction, carefully read the performance indicators of the tape to make it suitable for the environmental temperature and humidity during construction.

(2) According to different waterproofing membranes and construction methods, different types and sizes of adhesive tapes are selected.

(3) Before construction, the quality inspection of the previous project should be carried out, and after passing the inspection, the waterproof layer construction can be carried out.

(4) Construct waterproof rolls according to engineering design requirements, and ensure that the waterproof rolls are firmly bonded to the leveling layer without any hollowing. The waterproof layer after construction should be protected.

(5) When using adhesive tape on walls, attention should be paid to the firmness and smoothness of the bonding parts on the brick wall or concrete surface. If the surface is poor, cement slurry should be used for repair treatment to achieve a smooth and firm surface without floating sand.

(6) Lay and position the roll material, leaving the overlap width of the roll joint, and paste it. Waterproof membrane is fully laid; When adhesive and tape are used together at the overlapping part of the coil, the overlapping width of the coil is 80MM-100mm, and the tape width is 15MM-25mm.

(7) When only adhesive tape is used to bond the overlapping parts of the coil, the overlapping width of the coil is 50MM.

(8) Empty laying of waterproofing membrane; The overlapping part of the coil is bonded with tape, and the overlapping width of the coil is 60MM.

(9) For projects with high waterproof levels, 25MM single-sided non-woven tape can be used for edge sealing at the interface.

(10) Double sided tape is used for bonding between rolls and between rolls and substrate surfaces; Single sided tape is used for sealing and bonding the reverse interface and port area.
