- Application Instructions
Surface Preparation: All work surfaces should be clean, dry, 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 with an approved EPDM or TPO membrane cleaner prior to application of Millennium Single-Ply Primer.
Equipment Clean-up: Use Mineral Spirits or VM&P naptha. Observe all manufacturer’s safety precautions and use recommendations when using solvents.
- Thoroughly shake or stir Millennium Single-Ply Primer prior to use and re-stir every 15-20 minutes during use. Note: product may exhibit an “apple sauce” type texture even after agitation. This appearance is normal and will not adversely affect the product’s performance. For more information on primer appearance, see Millennium Single-Ply Primer Appearance Technical Bulletin.
- Do not dilute or extend Millennium Single-Ply Primer.
- Surfaces should be dry and clean before applying Millennium Single-Ply Primer. EPDM and TPO surfaces should be cleaned with a suitable solvent such as mineral spirits or VM&P naptha if necessary prior to priming. Observe all manufacturers’ safety precautions and use recommendations when using solvents. Do not smoke while working with primer.
- When the surfaces are dry, apply Millennium Single-Ply Primer with a fully saturated brush or scouring pad. The surface should appear wet during application. Apply primer to a wider area then the actual bonding area to insure complete coverage. If using a scouring pad, be sure that it is free of excessive dust from EPDM membranes. Replace pads often. Do not overwork primer.
- Allow primer to dry completely (typically less than 20 minutes) before applying tape. Primer will visually appear “dull” or “flat” and will feel dry to the touch. Drying conditions will vary depending on ambient air conditions. NOTE: Use caution when installlling at temperatures below 40°F (5°C) to prevent blushing of EPDM primer (formation of condensation on surface of primer).
- When not in use, keep lid on primer to prevent solvent evaporation. When finished, secure lid and store primer as recommended for use at a later date.
- Once the seam or flashing is installed the primer will take up to 48 hours to wet-out the tape surface and build full strength. Any peel tests on installed seams or flashings should not be conducted until at least 24 hours after installation. For more information, please see H.B. Fuller’s Technical Bulletin on Cool Cover™ TPO Adhesion Strength.
- Basic Use
Millennium Single-Ply Primer is used to prime EPDM and TPO roofing membrane to provide improved adhesion to the Millennium family of EPDM tapes, laminates, and sealants as well as H.B. Fuller’s Cool Cover™ line of TPO tapes, laminates, and sealants. Millennium Single-Ply Primer is an excellent choice for priming concrete, OSB, plywood, and metal surfaces.
- Limitations
- Do not use as a membrane cleaner.
- Talc, dust, oil, ice, snow, or wet conditions inhibit good adhesion.
- Clean and dry surfaces are a necessity.
- Not for use on PVC or TPO roof membranes.
- Do not use on extruded or expanded polystirene insulation.
- At Installation temperatures below 40°F (4°C) care must be taken to prevent the formation of condensation on surface of primer.
- Not for use in VOC regulated markets, use Millennium Primer 240 in those areas.
