3M™ Air & Vapor Through Wall Flashing Tape 3015TWF Features Can be used to flash a window opening or as a window flashing product. Exceptional puncture and abrasion resistance. Excellent adhesion to concrete, concrete block, anodized aluminum, galvanized metal, exterior gypsum sheathing and plywood. Primer not required in most applications. Flexible at low temperatures. Unique adhesive even adheres to damp surfaces that have not absorbed water, like metals, glass and plastics. Compatible with many building sealants including polyurethane, silicone and silane terminated hybrid sealants. Service temperature from -40°F to intermittently 240°F (-40° to 116°C). Can be applied from 0° to 150°F (-18° to 66°C) Resists UV exposure for up to 24 months. Surface Preparation To obtain the best adhesion, 3M™ Air & Vapor Through Wall Flashing Tape 3015TWF should be installed when outdoor temperatures measure above 0°F to 150°F (-18°C to 66° C). Excellent adhesion to concrete, concrete block, anodized aluminum, galvanized metal, exterior gypsum sheathing and plywood. Primer not required in most applications. Surfaces should be clean, free from dirt and debris and have not absorbed water. Surfaces should be free of any damaged, unsupported areas, sharp protrusions or voids. Concrete must be cured a minimum of 7 days before application. Block or brick walls should have mortar joints stuck flush. 3M™ Air & Vapor Through Wall Flashing Tape 3015TWF adheres to most common bui lding materials. For difficult-to-stick-to surfaces, test adhesion before application. If needed, apply 3M™ Hi-Strength 90, 3M™ Hi--Strength 94 ET Spray Adhesive, 3M™ ScotchWeld™ Holdfast 70, or 3M™ Fastbond™ Contact Adhesive 30NF to prime the substrate prior to applying the membrane. Application Instructions Overlap all joints by 50mm (2"). Keep 3M™ 3015 TWF back 12mm (½") to 25mm (1 ") from outside face of wall or veneer. Detail work must be carefully executed to ensure a continuously sealed building envelope: at all laps, seams, penetrations, and along top edges of 3015 TWF, apply a continuous bead of sealant such as 3M™ Polyurethane Sealant 540. Form end dams as required and use sealants at laps. Top or leading edge of 3M™ 3015 TWF must be sealed to prevent rain water from migrating behind the membrane.
