Ensure all surfaces are dry and clean, free from dirt, dust, grease, oil and silicones.

Ensure firm pressure is applied to the tape to provide the best adhesive bond, and that sufficient tape is applied (of at least 25mm) either side of joints to provide a long-lasting seal.


Remove the release paper from the section of GT1625HT™ reinforced aluminium foil FSK facing tape, taking care not to touch the adhesive surface.

Align the tape centrally over the join. Pull the tape taut and then press down firmly over the entire joint area.

Rub the tape to remove any wrinkles or folds.
