Roofing Underlay Repair Tape Sitko Repair 100mm x

Sitko Repair underlay repair tape is a butyl rubber-based fiber fabric tape, specifically designed for repairing underlays. Sitko Repair tape is used for patching and sealing nail holes and tears, as well as serving as a nailing seal between the underlay and the battens used for securing it.

The tape’s support structure is a dense film laminated from flexible polypropylene film and polypropylene fiber fabric. The vulcanizing butyl rubber adheres extremely well to clean, dust-free, and grease-free surfaces, creating an almost original-level seal for the underlay. Proper environmental and substrate temperature is required to ensure adhesion. Refer to the technical documentation for detailed instructions.

Sitko Repair underlay repair tape is part of the Tectis underlay system and is therefore an approved tape for patching above the underlay.
