Ardex WPM 300
Waterbased Epoxy Membrane
ARDEX WPM 300 (HydrEpoxy 300) is a two-component water-based epoxy polyamide membrane/barrier coating. Approved for use with potable (drinking) water, independent testing confirms conformity with the requirements of AS4020.2000 and BS6920.
Features/Benefits
- 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.
