Frequently Asked Questions

Q: What surfaces does the butyl aluminum foil tape adhere to?

A: This butyl tape bonds to a wide range of surfaces including metal (steel, aluminum, copper), glass, plastic, wood, concrete, brick, and most painted surfaces. For best results, ensure the surface is clean, dry, and free of loose particles before applying.

Q: Is this tape suitable for outdoor use and UV exposure?

A: Yes. The aluminum foil facing provides UV resistance, protecting the butyl adhesive underneath from direct sunlight and extending the overall lifespan of the seal. It is well-suited for outdoor roofing, flashing, and weatherproofing applications.

Q: Can this butyl tape be applied in cold weather?

A: Butyl rubber remains flexible at lower temperatures, making it more forgiving than standard acrylic tapes in cooler conditions. For optimal adhesion, try to apply in dry conditions above 5°C (41°F) where possible.

Q: How wide and long is the roll?

A: Please refer to the product variant selector for specific width and length options available. Multiple sizes are typically offered to suit both small patch jobs and larger roofing projects.
