PREPRUFE® Detail Tape

Product Description

PREPRUFE® Detail Tape is a specially formulated, two-sided, highly aggressive tape. It is a 2 in (50 mm) wide x 50 ft (15 m) long self-adhesive tape with a release liner.

PREPRUFE® Detail Tape is provided in Low Temperature and Hot Climate Grades as follows:

• PREPRUFE® Detail Tape LT Grade — for temperatures between 25°F (-4°C) and 86°F (+30°C)
• PREPRUFE® Detail Tape HC Grade — for use in Hot Climates (minimum 50°F (+10°C))

Use

PREPRUFE® Detail Tape is ideally suited for the following uses:

• As a detailing accessory to the PREPRUFE® and PREPRUFE® SCS Systems
• Adhering HYDRODUCT® drainage composites and insulation boards to waterproofing membranes

Application

Surface Preparation

All surfaces must be clean, dry and free from dirt, grease, oil, dust or other contaminants.

PREPRUFE® and PREPRUFE® SCS Systems

PREPRUFE® Detail Tape must be rolled firmly into place prior to removing the release liner. Ensure the release liner is then removed prior to adhering the next piece of membrane to the PREPRUFE® Detail Tape, which then must be rolled into place as well over the PREPRUFE® Detail Tape. Refer to applicable system detail drawings at references.gcpat.com.

Supply

HYDRODUCT® drainage composites

Where HYDRODUCT® drainage composites are placed horizontally from rolls onto a wall, a continuous strip of PREPRUFE® Detail Tape near the top and another strip near the bottom is recommended. If the drainage composite is cut and applied vertically in 6 to 8 ft (1.8 to 2.4 m) lengths, a strip is recommended near the top, another near the middle and a third near the bottom.

On decks, a strip of tape is recommended at approximately 10 ft (3 m) intervals, or more frequently in the event of high wind. Unroll the tape and adhere to the waterproofing membrane. Leave the release sheet on the tape until just before applying the drainage composite. The tape and release liner may be cut with a utility knife. Peel the release liner and apply the drainage composite. Press the composite firmly to ensure good contact. For deck applications, the tape may be applied to the back of the drainage composite rather than to the waterproofing membrane, if it is more convenient.

Polystyrene protection board and insulation

On walls, apply a strip of tape near the top and bottom edge of the board or insulation. If the board is applied vertically in lengths of 8 ft (2.4m) or more, apply a third strip of tape in the middle of the board or insulation. Press panel firmly over the tape to ensure a good bond. PREPRUFE® Detail Tape may also be used to adhere polystyrene board or insulation in deck applications in the event of high winds.
