Product Description

Duram Multithane HV is a tough, durable, elastomeric, single pack, liquid applied, moisture curing, cross-linking, polyurethane waterproofing membrane – usually grey in colour.  Duram Multithane HV forms a tough, flexible, seamless waterproofing membrane designed for both vertical and horizontal surfaces that bonds well to most suitably primed building substrates. Duram Multithane HV is formulated as an anti-sag membrane, that although easy to apply by roller or brush, it can be applied on to vertical surfaces without slumping to achieve the require film thicknesses.

Product Uses

Multithane HV is not designed for long term direct exposure to UV and should be covered within six weeks.
• Multithane HV is not designed as a trafficable membrane although infrequent maintenance foot-traffic is acceptable
during the construction phase.
• Multithane HV is not suitable for direct and prolonged contact with concentrations of chlorine above 10 ppm.
• Direct tile adhesion is not advised. Please note: for direct tile bond applications seek Duram technical advice.
• Multithane HV cannot be applied directly to damp surfaces as this will cause gassing and bubbling of the membrane.
• In exposed areas, Multithane HV must be coated with Duram Multithane ATC or covered.
• Multithane HV cannot be applied to slightly damp surfaces the product will not adhere. The surface must dry before the
membrane can be applied, freedom from surface water and continual dampness is essential.
