Ardex WPM 300

ARDEX WPM 300 (HydrEpoxy 300) is a two-component, water-based epoxy polyamide membrane/barrier coating. Approved for use with potable (drinking) water, it has been independently tested to confirm compliance with AS4020:2000 and BS6920.

We supply ARDEX WPM 300, designed to offer:

• Water Resistance: Prevents rising dampness and efflorescence while withstanding hydrostatic pressure.
• Excellent Adhesion: Bonds effectively to various substrates, including damp surfaces and freshly laid green concrete.
• Safety for Sensitive Locations: Ideal for environments requiring careful consideration and safety.

Features/Benefits Include:

• Non-flammable and negligible odour
• Can be applied to damp surfaces
• Can be safely applied to freshly laid hardened (green) concrete
• Conforms to requirements of the Building Code of Australia as a waterproofing membrane
• Conforms to the requirements of Australian standard 4020 – 2000 and British Standard 6920 for use in contact with potable water
• When applied directly to the substrate, the cured membrane will withstand 250kPa of hydrostatic pressure which is equivalent to a 25 metre head of water
• When used wet on wet over ARDEX WPM 256 Bonding Bridge the cured membrane will withstand 400kPa of pressure which is equivalent to 40 metre head of water
• Can be overcoated using almost any decorative or industrial finishing paint
• Prevents rising dampness and the formation of efflorescence when used as a single-coat barrier coat
• Has excellent adhesion to most substrates, including brick, masonry, concrete block, concrete, stone and timber
• Easy clean-up using water

Typical Applications

• As a low water vapour transmission coating in the building and construction industries and as a barrier/seal coating over freshly laid or damp concrete
• As a hydrostatic pressure-resistant waterproofing membrane to prevent water seepage or dampness penetration through to the interior of walls and floors
• As a waterproofing barrier on the negative side in below-grade surfaces such as basements, tunnels, liftwells, retaining walls and carparks
• As a waterproofing membrane or barrier coating over freshly laid hardened (green) concrete, prior to the application of conventional levelling compounds, carpet and tile adhesives
• As a waterproofing membrane in tanking applications, including potable water containment
• As a barrier seal coating over damp, green or efflorescence-producing concrete prior to overcoating with conventional building paints.
