Q: What is Supermax Flex?

A: Supermax Flex is a high performance, moisture cured, single component, glass fibre-reinforced polyurethane, for use on new and existing flat roofs and it has been developed to reduce project time. Utilising the latest fast-curing technology, this system will cure in as little as 6-12 hours (at 20°C). It is also damp tolerant and can be laid at 5°C.

Q: What is Supermax Flex Plus?

A: Supermax Flex Plus is the same as the standard Flex system except it has an additional additive incorporated into the resin to make the system cure faster in cold weather

Q: Where can Supermax Flex be installed?

A: Supermax Flex can be used on both domestic and commercial new build and refurbishment projects. From something as small as a porch, through to apartment blocks, leisure centres, hospitals, box gutters, timber framed buildings and right up to factory roofs which can be 1000’s of sq. metres without the need of expansion details. Due to the properties of Supermax Flex, it can also be used on vertical faces without any slumping occurring.

Q: Can I use Supermax Flex over my existing flat roof surface?

A: Yes, Supermax Flex can be installed directly onto existing and old roof surfaces. A primer could be required depending on the substrate. We would recommend a survey to ensure the structure is suitable for overlaying prior to installing (check condition of subdeck, etc.).

Q: What substrates can Supermax Flex be applied onto?

A: Supermax Flex can be installed onto most surfaces, such as felt, asphalt, concrete, metal, OSB3, plywood, foil faced carrier membrane, GRP, EPDM, PVC single ply, asbestos, lead, aluminium liquid-applied systems, plus many more with the additional benefit of not needing to use a primer, so no waiting around.

Q: Can you walk on a Supermax Flex roof without it getting damaged?

A: Yes, a Supermax Flex roof will withstand foot traffic. You can also add slate granules to the finish to give it a non-slip finish and more hard wearing.

Q: What other application can you use the Supermax Flex system for?

A: Supermax Flex can also be used for irrigated green roofs or roof gardens, inverted warm roofs and zero fall roofs applications. Paving slabs and decking can also be installed onto a fully cured Supermax Flex roof.

Q: Do I need to use reinforcement with Supermax Flex?

A: Yes, reinforcement is required Supermax Flex, this can be either 225gm CSM or 60gm Polyester Fleece.

Q: Do I need a catalyst to make it cure?

A: Supermax Flex is fully moisture cured, so no catalyst is required.

Q: How long does it take to cure?

A: Supermax Flex skins over and watertight after approximately 4 hours and can accept foot traffic after 24 hours to apply the topcoat. These timings are weather dependent; in colder weather it can take longer and in summer it can be quicker. If a catalyst is used, this speeds the process up.

Q: It sounds like Supermax Flex is very easy to use and anybody can install it, do I need training?

A: Supermax Flex is easy to, but we do recommend training is carried out before using for the first time. If you are unsure, you should contact a trained person to carry out the work.

Q: Is it a safe system to install?

A: Yes, very. Supermax Flex is a cold applied system which requires no hot works, making it very safe to use. It does not require mixing with a catalyst and is simple to apply with a roller or a brush. This not only allows for fast application; it eradicates the risk of human error caused by incorrect mixing ratios.

Q: Why would I use Supermax Flex instead of other cold applied liquid systems.

A: You would use Supermax Flex over other systems such as GRP for a number of reasons, such as: it can be applied to substrates that GRP cannot be used on (primers required for certain substrates), no catalysts required (money saved), no expansion joints required (potential weak spots), less materials wastage (due to no catalyst and curing too quickly) which in turn makes it a lot quicker to install as it is applied directly from the can.

Q: Does Supermax Flex have fire certification?

A: Yes, Supermax Flex has achieved B roof (t4) in accordance with EN 13501-5: 2016. Test method: CEN/TS 1187: 2012 Test 4.

Q: How long is Supermax Flex guaranteed for?

A: The length of guarantee is 25 years. In addition to the materials guarantee, a Supermax Flex roof is backed by a workmanship guarantee which runs concurrently with the materials guarantee.

Q: Can a Supermax Flex roof be repaired, should it become damaged?

A: Yes, in the unlikely event of damaging the roof membrane, the repair of minor damage to the system can be achieved effectively by cleaning back to the unweathered material and recoating the damaged area with the Supermax Flex system.

Q: What are the other benefits of a Supermax Flex roof?

A: Firstly, it is totally seamless, there are no joints, seems or welds meaning there are no weak spots on the roof with the potential to fail. It is resistant to temperatures of over 90°C for long periods. Supermax Flex is also a fully bonded system, which means it is resistant to wind uplift.

Q: Is Supermax Flex compatible with GRP edge trims?

A: Yes, all our systems are compatible with standard GRP edge trims.

Q: What temperature range can you use Supermax Flex?

A: Supermax Flex can be used between 5°C and 35°C.
