Frequently Asked Questions About Hi-Flex 50
Q: What types of surfaces can Hi-Flex 50 be used on?
A: Hi-Flex 50 is compatible with a wide range of surfaces, including masonry, brick, metal, timber, plastics, stone, painted surfaces, rubber, fibreglass, porcelain, aluminium, and powder coat. Always perform a preliminary adhesion test.
Q: Can Hi-Flex 50 be used for underwater applications?
A: No, Hi-Flex 50 is not suitable for long-term water immersion or internal swimming pool applications. Avoid exposure to high levels of chlorine.
Q: What is the cure time for Hi-Flex 50?
A: The cure rate is 3.0mm per 24 hours from surfaces exposed to the atmosphere at 25°C and 50% humidity. Cure times can vary depending on atmospheric conditions and the porosity of the substrate.
Q: Does Hi-Flex 50 require a primer?
A: Hi-Flex 50 offers primer-less adhesion on most non-porous substrates. However, for optimal adhesion in critical applications, priming may be necessary. Refer to the Adheseal primer selection chart.
Q: How do I clean up Hi-Flex 50?
A: While the product is still wet, tools and spills can be cleaned with Xylene. Cured product can be removed by mechanical means. For cleaning skin, use Adheseal citrus wipes.
Q: Is Hi-Flex 50 environmentally friendly?
A: Yes, Hi-Flex 50 has a low VOC content (1.5% USEPA) and meets "green star" environmental criteria, making it a sustainable choice for various applications.

How to apply Hi-Flex 50:
- Surface Preparation: Ensure surfaces are clean, dry, and free from contaminants. Use the two-wipe process for impervious substrates and allow concrete to cure for at least 28 days.
- Priming (If Required): For optimal adhesion on porous substrates, use Everflex Supaprime. For non-porous substrates, use Adheseal 50A surface prep. Allow 30 minutes to 2 hours before applying the sealant.
- Joint Design: Aim for a 2:1 width-to-depth ratio. Use a backing rod for joints deeper than 10mm and bond breaker tape for flat joints to prevent three-sided adhesion.
- Application: Cut the nozzle at a 45° angle for sealing or 90° for adhesive applications. Apply sealant in a continuous bead, ensuring good contact with both sides of the joint.
- Tooling: Tool off with a moistened spatula within 5 minutes of application. Remove masking tape while the sealant is still wet.
- Clean Up: Clean tools and spills with Xylene while the product is wet. Use Adheseal citrus wipes for skin cleaning.
