Product Description
PREPRUFE® Tape is a specially formulated two sided, reinforced pressure sensitive tape. The bottom side of the tape has a highly aggressive pressure sensitive adhesive which is designed to adhere to penetrations, protrusions and GCP waterproofing membranes and accessories. The top side of the tape has a pressure sensitive adhesive, a weather resistant protective coating an a release liner. Concrete is cast directly against the top adhesive side of the tape. The specially developed PREPRUFE® adhesive layers work together to form a continuous and integral seal to the structure.

- PREPRUFE® Tape LT - for temperatures between -5°C and +30°C.
- PREPRUFE® Tape HC - for use in Hot Climates minimum 10°C.

Application
Wipe substrates to receive PREPRUFE® Tape clean to remove any dirt, dust or moisture. Clean the surface of penetrations or protrusions with a wire brush to remove dirt, dust, rust and loose particles.
Unroll the tape and adhere the exposed pressure sensitive adhesive surface to the membrane or penetration. The protective coating surface of the tape should face toward the concrete to be cast onto the tape.
Use heavy hand pressure or a hand roller to maximize adhesion. Remove the release liner during application. Ensure the plastic release liner is removed from all areas of PREPRUFE® Tape. It is recommended that concrete be poured within 56 days (42 days in hot climates)
of application of the tape. Concrete must be placed carefully and consolidated properly to avoid damage to the membrane. Never use a sharp object to consolidate the concrete. Provide temporary protection from concrete over splash for areas of the tape that are adjacent to a concrete pour.
