Product (Multithane STD) Description

Multithane Std is a single pack, liquid applied, moisture curing, self-levelling, waterproofing membrane which cures to form a seamless, tough, durable, elastomeric (class 3 ) waterproofing membrane. Multithane Std bonds well to most suitably primed building substrates and is suitable for above and below ground applications. Colour: Grey. Multithane Std meets the criteria of: • AS4858:2004 Wet Area Membranes • AS4654.2 Exterior, for non UV exposed applications • the ‘Green Star’ environmental criteria. The product exhibits excellent chemical resistance and has been formulated to inhibit biological growth. Multithane Std is one of four versions within the Multithane range which include: Multithane UV; Multithane HV (High Viscosity anti-‘sag’) and Multithane HV UV. Please refer to these product data sheets for more information.

Product (Multithane STD) Uses

Multithane Std is designed to waterproof most non-exposed applications within the building and construction industry including: Tiled or Covered Areas: Shower recess & wet areas (floors and upturns), decks, balconies, terraces, podiums, retaining walls, planters & landscaped areas, structural slabs, water retaining structures (e.g. tanks), pits and bunding areas.

Suitable(Multithane STD) Surfaces

Multithane Std is suitable for most building substrates including: Concrete • Cement • Cement Render • FC and CFC Sheeting • Render • Brick • Block work • Plaster Board • Masonry • Bitumen (when primed with Duram Prime seal) • Metal • Timber, Particle Board, Plywood ( when primed with Duram Prime seal) and metal (if primed with a metal etch primer). Note: Particle Board is not regarded as a suitable substrate for wet areas and particularly shower recesses and should be replaced with CFC sheeting. As a minimum, Particle Board should be sealed with one to two coats of Duram Primeseal. All joins and corners must be sealed with a polyurethane sealant and a reinforced fabric used in conjunction with the membrane.

• Multithane STD is not designed for long term direct exposure to UV and should be covered within six weeks.
• Multithane STD is not designed as a trafficable membrane although infrequent maintenance foot-traffic is acceptable
during the construction phase.
• Multithane STD 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 STD cannot be applied directly to damp surfaces as this will cause gassing and bubbling of the membrane.
• In exposed areas, Multithane STD must be coated with Duram Multithane ATC or covered.
• Multithane STD 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
