Frequently Asked Questions
What surfaces does it suit?
It suits steel, aluminium, glass, concrete, brick, ceramic, terracotta roof tiles and more, making it a general-purpose roof and gutter sealant across the common building materials.
Is it safe for a drinking water tank?
Yes. The translucent and grey versions are suitable for drinking water as per AS/NZS 4020 and meet ATS 5200.014:2004, so they are safe for metal water tanks feeding a house.
Why translucent instead of grey?
Translucent gives a lower-visibility seal on light or metallic surfaces, while grey gives a defined line. Both carry the same drinking water suitability.
Can I use it on Colorbond?
Yes. It is made for lap joints in Zincalume, Colorbond and other decorative sheet metal, which is the core roofing and gutter application.
