1/ Extreme Elongation & Recovery
Flex stretches to accommodate continuous thermal and structural movement without rupturing, and recovers — making it ideal for the relentless expansion and contraction cycles of metal roof sheeting.
2/ Bonds Across Dissimilar Substrates
Flex adheres to galvanised steel, aluminium, concrete, wood, and fibre-cement. At transitions between different materials — such as a metal fascia meeting a concrete parapet — Flex maintains a continuous, movement-tolerant seal.
3/ Crosslinks Between Coats
Each coat of Flex crosslinks with the previous one to form a single homogenous film. Multiple coats increase film thickness and elongation, allowing the system to bridge progressively wider cracks without failure.
4/ Colourfast & UV Stable
Flex retains its colour and flexibility under continuous UV exposure. It does not embrittle or chalk in South Africa's high-UV environment, maintaining its elongation properties over the life of the system.
5/ Easy to Apply
Flex can be applied by brush, roller, or airless spray, making it practical for detail work on screwlines and overlaps as well as broader crack treatment on slabs. It is water-based, non-flammable, and odourless.
6/ Low VOC & Eco-Friendly
Flex is a low-VOC, non-APEO, styrene-acrylate copolymer dispersion. It is safe to use in occupied buildings and complies with responsible environmental standards.
7/ Wide Temperature Performance
Flex maintains its elongation and tensile strength balance across a wide temperature range — from cold winter mornings to the peak surface temperatures of a Highveld summer metal roof.
