Vapor Barrier Poly Seam Tape – 145VT Series – Rubber Adhesive

For stucco and plaster masking applications. Resists outdoor exposure, moisture, chemicals and weathering.

Suitable for floor underlay splicing.

Red color provides high visibility to ensure seam splice has been completed.


Our 145VT Poly Seam Tape is an ideal choice for all stucco and plaster masking applications.


  • For use in splicing poly for floor underlayment and/or splicing of poly films or hanging of poly films in abatement applications. Low WVTR rating ensures moisture containment.
  • For outdoor masking.
  • Sunlight (UV) exposure applications.
  • For outdoor applications where the tape is required to perform over an extended period of time but will offer easy, residue-free removal.

Features & Benefits

  • Specially designed adhesive virtually eliminates residue even after extended exposure.
  • High quality adhesive holds even on rough surfaces.
  • Easy unwind. Conformable.
  • Bright red color for visibility. White to blend in with white films.
