Ardex WPM 300 Water-Based Epoxy Waterproofing Membrane for Positive & Negative Water Pressure
WPM 300 is a two-component, reactive, light grey water-based epoxy polyamide waterproofing/damp-proofing coating. With high adhesion to substrates, it can be used on damp substrates and freshly placed concrete, suppressing rising damp, reducing efflorescence and resisting hydrostatic (negative) pressure. Complies with Australian AS 4020-2000 national standard, approved for drinking water use.
