W.R. Meadows AIR-SHIELD 25 MIL FLASHING TAPE is a self-adhering, flexible membrane flashing. It is a roll-type product that is nominally 25 mils thick. This material is an air, vapor, and liquid moisture barrier. When properly applied, the product reduces the risk of rot and mold development.  Sold by the roll.

Features and Benefits

• Easy to install.
• Reduces the risk of rot and mold development.
• Superior adhesion.
• Seals around fasteners.
• Watertight

Applications

• AIR-SHIELD 25 MIL FLASHING TAPE provides protection against water infiltration in critical detail areas, such as window and door openings, deck-to-wall intersections, corner boards, wall-to-wall tie-ins, foundation sill plates, sheathing panel seams, under stucco finishes, masonry walls, and other non-roof detail areas.

Procedure

Surface Preparation

Apply AIR-SHIELD 25 MIL FLASHING TAPE in fair weather conditions when the air, surface and membrane are at temperatures of 25° F (-4° C) or higher. After precipitation, allow a minimum of 24 hours for drying before installation. Install directly onto a clean and dry surface. Remove dust, dirt, and loose nails. Protrusions must be removed. Surfaces should have no voids or damaged/unsupported areas. Repair surfaces before installing. Surfaces should be free of scale, rust, grease, and oil and primed with MELPRIME™ or MEL-PRIME W/B from W. R. MEADOWS.

Application Method

Cut AIR-SHIELD 25 MIL FLASHING TAPE to desired length. Peel back the release paper to expose adhesive. Align the membrane and press into place with heavy
hand pressure. Laps must be a minimum of 3” (75 mm). Mechanically fasten the membrane at all vertical terminations. Use only smooth shank fasteners. Consistent with good construction practice, install the membrane so that all laps shed
water (following the shingle principle). The top membrane layer should go over the bottom layer. Always work from low point to high point.

Precautions

Do not leave the product permanently exposed to sunlight. Maximum recommended exposure time is 30 days
