Frequently Asked Questions
Q: What surfaces can butyl waterproof sealing tape be applied to?
A: This butyl tape adheres to a wide variety of surfaces including metal roofing, aluminium flashing, wood, concrete, PVC pipes, glass, tiles, and fibreglass — making it highly versatile for both indoor and outdoor sealing applications.
Q: How do I apply butyl tape for roof flashing or gutter repairs?
A: Application is straightforward. First, clean and dry the surface thoroughly to remove dust, grease, or loose debris. Then peel off the backing liner and firmly press the tape onto the target area, smoothing out any air bubbles as you go. For best results, apply when the surface temperature is above 5°C (41°F).
Q: Which width should I choose for my project?
A: Choose 5cm for narrow seams, joints, or pipe wrapping. Opt for 10cm or 15cm for standard gutter seams and flashing edges. The 20cm width works best for larger roof patches, wide flashing sections, or covering broader gaps on RV awnings and boat surfaces.
Q: Is this butyl sealing tape suitable for permanent outdoor use?
A: Yes. The butyl rubber compound is formulated to withstand prolonged outdoor exposure, including UV radiation, heavy rain, frost, and heat. It maintains its flexible, watertight bond season after season without cracking or drying out.
