Applications & Uses

Application Method

1. The entire surface where Millennium EPDM Seam Tape will be applied must be cleaned and primed.

2. Mark the membrane where the edge of the splice occurs and then fold the top portion back. Apply EPDM primer to both sides of membrane using the supplied scrub pad. Scrub the membrane thoroughly while the primer is wet moving up and down the seam area. NOTE: Use caution when installlling at temperatures below 40°F (4°C) to prevent blushing of EPDM primer (formation of condensation on surface of primer).

3. Allow the primer to dry to the touch (no material transfer, typically less than 20 minutes). Dry time will vary depending on ambient temperature and humidity.

4. Position the Millennium EPDM Seam Tape over the primed splice area along the marked edge. Press in by hand. Verify that approximately 1/8” (0.3cm) of tape extends beyond splice edge.

5. Roll the top surface of the release liner to promote adhesion to the bottom substrate.

6. Allow the EPDM membrane to fall freely onto the Seam Tape. Remove release liner at a 45º angle.

7. Immediately roll the splice with a 2” (5.08cm) wide silicone roller. Roll perpendicular to splice edge.

8. Seal edge of seam detail with patented Millennium EPDM Edge Sealant.*

Note: Millennium Single Ply Primer and Millennium Primer 240 are designed to dry with little or no tack. When dry, the primed seam area will feel completely “clean” to the touch. Other primers are designed to remain “tacky” to the touch in the dry state. With all primers, allow up to 24 hours after installation and rolling for taped seam to build maximum strength.

Basic Use

Millennium EPDM Seam Tape is designed for field splicing of EPDM membranes.

Limitations

• Not for use on PVC roof membranes.
• Not for use in high traffic areas.
• Talc, dust, oil, ice, snow, or wet conditions inhibit good adhesion. Clean and dry surfaces are necessary for proper Installation of this product.

Surface Preparation

All work surfaces should be clean, dry, and free of dirt, dust, debris, oils, un-adhered coatings, deteriorated membrane and other contaminants that may result in a surface that is not sound or is uneven. If necessary, clean the surface to receive the flashing with an approved EPDM membrane cleaner.
