Remove any sharp protrusions and repair all defects. Apply AIR-SHIELD BUTYL FLASHING in dry conditions between -12\u00b0 to 48.8\u00b0 C air, surface, and membrane temperatures.\u00a0 Minimum application temperature is -12\u00b0 C and rising.\u00a0 After precipitation, allow a minimum of 24 hours for drying before installation.\u00a0 Ensure surface is free of dew.\u00a0 All protrusions, sharp edges, or points must be removed.\u00a0 Surfaces should have no voids or damaged\/unsupported areas. Repair surfaces before installing.<\/p>\n<p>Certain project and\/or substrate conditions may require the use of a primer, such as <a href=\"https:\/\/can.wrmeadows.com\/en-ca\/mel-prime-canada\/\">MEL-PRIME<sub>\u2122<\/sub><\/a>.\u00a0 Please contact W. R. MEADOWS for more information.<\/p>\n<p><strong>Existing Concrete \u2026 <\/strong>Concrete surface must be clean and dry with all chemical form agents, stains, oil, grease, dust and dirt removed prior to application.<\/p>\n<p><strong>Application Method \u2026 <\/strong>Cut AIR-SHIELD BUTYL FLASHING to desired length. Peel back the release paper to expose adhesive.\u00a0 Once positioned, immediately hand-rub AIR-SHIELD BUTYL FLASHING firmly to the surface, removing any bubbles or wrinkles, then pressure roll using a vinyl floor roller three times over the entire surface to assure positive adhesion.\u00a0 Adhesion will take 24 hours to fully develop.\u00a0 Laps must be a minimum of 2.5\u2033 (63.5 mm).\u00a0 Consistent with good construction practice, install the membrane so that all laps shed water (following the shingle principle).\u00a0 The top membrane layer should go over the bottom layer. Always work from low point to high point which ensures a shingle overlapped condition.<\/p>\n<p><strong>LIMITATIONS<\/strong><\/p>\n<p>AIR-SHIELD BUTYL FLASHING can be exposed for periods up to 24 months.\u00a0 Installed membrane is not designed for permanent UV exposure and should be covered as soon as reasonably possible to prevent UV and other construction damage.\u00a0 Do not apply to wet, damp, dew-covered, contaminated, dirty, or frost-covered surfaces.\u00a0 Depending on surface, a solvent wipe may be needed to remove any surface film to ensure optimal adhesion.<\/p>\n<p>Surface moisture, as with all primerless adhesives, will adversely affect performance.\u00a0 Product is not suitable for TPO and silicone roofing, most polyurethane sealants, creosote, coal tar products, EPDM, and flexible PVCs. AIR-SHIELD BUTYL FLASHING is compatible with rigid PVC\/vinyl membranes.<\/p>\n<p>The use of a termination bar or mastics such as <a href=\"https:\/\/can.wrmeadows.com\/en-ca\/bem-canada\/\">BEM<\/a> or <a href=\"https:\/\/can.wrmeadows.com\/en-ca\/pointing-mastic-canada\/\">POINTING MASTIC<\/a> from W. R. MEADOWS may be required in certain applications.<\/p>\n<p>Membrane adhesion of self-adhesive membranes on oriented strand board (OSB), fire-rated treated lumber, concrete or concrete block can sometimes be affected by the level of surface texture, the presence of wax, treatments, or dust. In situations where the membrane adhesion is a concern due to substrate type, in-situ adhesion tests should be performed to determine suitability of substrate prior to full installation. If there are variations in the OSB surface, multiple tests may be required.<\/p>\n<p>2025-02<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/can.wrmeadows.com\/pics\/foot-can.jpg\" alt=\"\" width=\"640\" height=\"98\" \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/can.wrmeadows.com\/pics\/footer-can.jpg\" alt=\"warranty\" width=\"614\" height=\"212\" align=\"BOTTOM\" border=\"0\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>AIR-SHIELD BUTYL FLASHING is a primerless, composite membrane that is comprised of a white woven polyethylene facer and easy-to-release split-face PET (polyester) clear film backing.
