Product Characteristics:

  • Colour: Grey
  • Size: 15 Litre

Product Specification:

  • Complies with AS4858:2004 Wet Area Membranes.
  • Complies with AS4654.1 2012 Waterproofing membranes for external above ground use. Exposed areas must be topped with Multithane ATC.
  • Complies with AS3740:2010 Waterproofing of Domestic Wet Areas.
  • Meets the 'Green Star' environmental criteria.

Multithane STD is part of the Multithane range, which includes Multithane UVR (UV resistant) and Multithane HV (High Viscosity, High Hold). Please refer to the respective product data sheets for more information.

Recommended Surfaces:

Multithane STD is formulated for long-term waterproofing in non-UV exposed applications and is suitable for various surfaces, including:

  • Balconies
  • Terraces
  • Decks
  • Podiums
  • Tiled or covered areas
  • Roofs (non-exposed)
  • Roofs (exposed) when top coated with Multithane ATC
  • Shower recess & wet areas (floors and upturns)
  • Retaining walls
  • Planters and landscaped areas
  • Structural slabs
  • Water retaining structures (e.g., tanks)
  • Pits and bunded areas
  • Door flashings
  • Concrete
  • Cement and cement render
  • FC and CFC Sheeting
  • Block & Brickwork
  • Masonry/Stone
  • FC, CFC, asbestos, and Blue board sheeting
  • Particle board (see notes below) *
  • Scyon & composite sheeting
  • Acrylic coatings
  • Vitreous, ceramic & terra cotta tiles
  • Bitumen (when primed with Duram Primeseal MC)
  • Metal (when primed with Duram ME Primer / Primeseal MC)
  • Timber, Particle Board, Plywood (when primed with Duram Primeseal MC) *
  • Masonite
  • Plasterboard
  • Extruded foam
  • Fibreglass/Gelcoat/PVC

Advice from Duram should be sought for the most appropriate priming method for these surfaces as Duram has recommended systems for all of the above.

*Note: Particle Board is not regarded as a suitable substrate for wet areas, particularly shower recesses, and should be replaced with CFC sheeting. At a minimum, Particle Board should be sealed with one to two coats of Duram Primeseal MC. All joins and corners must be sealed with a polyurethane sealant, and a reinforced fabric used in conjunction with the membrane. Surfaces must be sound, stable, dry, clean, and free of dirt, dust, and contaminants, and suitably primed.

  • Low VOC levels, meets the 'Green Star' environmental criteria
  • Permanently flexible with excellent flexibility (tests show flexibility < 500% - Class III)
  • Bitumen and tar-free, does not stain grout or tiles
  • Self-leveling, 100% bonded seamless membrane without joints or laps
  • Suitable for immersion in water
  • Formulated for wet area and under tile use
  • Safe to use
  • Suitable for permanent immersion and demanding waterproofing applications
  • Excellent chemical and hydrostatic resistance
  • Tough, durable, and flexible
  • High strength and puncture resistance
  • Easily repaired and maintained
  • Easy to apply, odourless when cured
  • Formulated to provide long-term protection
  • Inhibits mold and biological growth
  • Australian Made with a long history of Australian use
  • Can be overcoated with Rocktuff for trafficable areas or Multithane ATC for UV protection
  • Meets the Class III High Extensibility classification of AS4654.1 2012
  • Can be installed in accordance with AS3740:2010 wet area and AS4654.2 exterior, in exposed membrane applications in conjunction with Multithane ATC
  • Does not re-emulsify once fully cured, providing long-term performance

Limitations:

  • 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 chlorine concentrations above 10 ppm.
  • Direct tile adhesion is not advised. 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 surface must dry before the membrane can be applied. Freedom from surface water and continual dampness is essential.
