Composition & Materials:

WHITE POLYETHYLENE TAPE is a polyethylene film, single coated with a rubber pressure sensitive adhesive. WHITE POLYETHYLENE TAPE releases easily off of the roll which prevents stretching and curling during and after installation. WHITE POLYETHYLENE TAPE is designed and manufactured with a serrated edge to facilitate easy roll tear off during installation.

3.3 Size & Packaging:

WHITE POLYETHYLENE TAPE is available in 4” x 180’ rolls. There are 12 rolls per case and 36 cases per pallet.

3.4 Weight:

WHITE POLYETHYLENE TAPE weighs approximately 5 pounds per roll yielding approximately 60 pounds per case.

Benefits:

• Aggressive Adhesion
• Serrated Edge for Ease of Installation
• Very Low Water Vapor Permeance
• Struggle Free Release from Roll
• Suitable for All Plastic Type Vapor Barriers
• 4” Wide Rolls for More Area of Adhesion

Environmental Considerations:

When sealing vapor barrier overlaps, WHITE POLYETHYLENE TAPE helps control soil gas and poisons such as methane, radon, sulfates and petroleum contaminated soil.

Installation

Sub-Grade Preparation:

Level and tamp or roll granular base as specified by the architectural or structural drawings.

Vapor Barrier Placement:

Unroll vapor barrier with the longest dimension parallel with the direction of the pour. Unfold vapor barrier to full width. Lap vapor barrier over the footings and seal to the vertical foundation walls with either WHITE POLYETHYLENE TAPE, VIPER® DOUBLE BOND TAPE, VIPER® VAPORPATCH or VAPORCHECK® MASTIC.

Surface Preparation:

When installing WHITE POLYETHYLENE TAPE, VIPER® DOUBLE BOND TAPE, VIPER® VAPORPATCH or VAPORCHECK® MASTIC, make sure the area of adhesion is free from dust, dirt and moisture to allow maximum adhesion.

Seams and Penetrations:

Seal around pipes, support columns or any other penetration with VIPER® VAPORPATCH, VAPORCHECK® MASTIC or at minimum a combination of the vapor barrier and WHITE POLYETHYLENE TAPE. Doing so creates a monolithic membrane that isolates the surface of the slab from moisture sources below Holes or openings through vapor barrier should be effectively sealed with WHITE POLYETHYLENE TAPE, VIPER® VAPORPATCH or VAPORCHECK® MASTIC to maintain the integrity of the vapor barrier. Overlap joints a minimum of six inches. Seal overlap together with WHITE POLYETHYLENE TAPE and/or VIPER® DOUBLE BOND TAPE.

VIPER® VAPORPATCH Installation:

1. VIPER® VAPORPATCH is available in 12” X 50’ rolls. Cut patch to desired length using “dashed” guide line (printed between each pipe diameter template).
2. Cut an “X” through VIPER® VAPORPATCH to fit the diameter of the pipe (Grid ranges from one to eight inches).
3. Slide VIPER® VAPORPATCH tightly over pipe penetration.
4. Peel off the release paper (exposing the all weather adhesive) and firmly apply to the vapor barrier and pipe.
5. Seal off any exposed area with VAPORCHECK® MASTIC or WHITE POLYETHYLENE TAPE.
