WPM 300

WPM 300

Water based epoxy membrane


WPM 300 is a two component, high build, water based epoxy polyamide membrane/barrier coating with excellent resistant to hydrostatic pressure and good bond to damp surfaces. It is suitable for areas such as potable water tanks where a tough, hard wearing protective surface resistant to corrosion, chemical attack and bacterial growth is necessary.

WPM 300 is approved for use with potable (drinking) water, independent testing confirms conformity with the requirements of AS/NZS 4020:1999 and BS 6920:2000.


• Excellent adhesion to damp surfaces and freshly laid green concrete.
• Water resistant: prevents rising damp and efflorescence.
• When applied directly to the substrate the cured membrane will withstand hydrostatic pressure of 25 metre head of water.
• When used wet on wet over WPM 200 the cured membrane will withstand hydrostatic pressure of 40 metre head of water.
• Non-flammable and negligible odour: safe to use in sensitive locations.
• Can be overcoated using almost any decorative or industrial finishing paint.
• Conforms to requirements of CFTRI and international standards (AS/NZS 4020:1999 and BS 6920:2000) for use in contact with potable water.
