Sealing Corners With Zip System Tape

October 30, 2020


Seal the structural sheathing against air and water leaks


Step by step:

  • To install the ZIP System tape to the outside corner, secure the tape evenly to one side of the corner.
  • Roll out the tape until it overlaps the previously installed piece of tape, then cut the piece of tape.
  • Next, fold the tape over the corner, pulling it tightly across the corner. Make sure the tape is overlapped at least two inches.
  • Use the roller to make sure the tape has good adhesion to the corner and the ZIP System surface.
