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.

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 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)
• 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.

Coverage

The stated average coverage rate may vary depending upon type, condition, porosity, texture of the surface and application technique. Multithane Std: Generally, 1.5 to 2.0 Lts per m² for two coats combined, i.e. 0.75 to 1.0 Lts per m² per coat. Ensure that the dry film thickness of the cured membrane is at least 1.2mm. Minimum thickness per coat is 0.6mm.
