Abstract:
To provide a lap tape, a terminal tape, and a method for waterproofing a coating film aiming at prevention of discoloration.
A lap tape T is attached on an abutting portion or an overlapped portion of ends of a plurality of waterproof sheets laid adjacent to a base surface. The lap tape T includes a substrate 1, a blocking layer 2 provided on one surface of the substrate 1, and a butyl-based or modified asphalt-based self-adhesive layer 3 provided on one surface of the blocking layer 2. The blocking layer 2 blocks oil leaching from the adhesive layer 3, thereby preventing the oil from moving to the substrate 1.
