ARDEX Superflex WPM 001 - Pre-Mixed, Acrylic, Liquid Waterproofing Membrane
Description

ARDEX Superflex WPM 001 is a tough, ready to use acrylic waterproofing membrane specially designed for use under tiles. ARDEX WPM 001 is flexible, safe to use, low in odour, and fully compatible with ARDEX polymer-modified tile adhesives.

Key Features
  • BRANZ Appraised (No. 472 & 473)
  • CSIRO Appraisal (No. 91)
  • Flexible
  • Safe and ready to use - Low VOC
  • Low in odour
  • Fully compatible with polymer tile adhesives
  • Fast drying on part acrylic – ready to tile in 48 hours at 23°C
  • High strength
  • Formulated with synthetic microfibres to eliminate the need for a separate reinforcement mat
Scope of Use

ARDEX WPM 001 Superflex is for use as a waterproofing membrane for internal wet areas of buildings, including floor substrates of concrete, flooring grade particleboard, plywood, and fibre cement sheet tile underlay, and on wall substrates of wet area fibre cement sheet lining systems and wet area plasterboard lining systems. It is also suitable for use where floors have been designed and constructed such that deflections do not exceed 1/360th of the span, and when protected from physical damage by ceramic or stone tile finishes.

Limitations on Use
  • ARDEX WPM 001 Superflex cannot be used in areas subject to negative hydrostatic pressure or rising damp, unless treated with ARDEX WPM 300.
  • It cannot be used where rain is imminent, where the membrane will be left exposed and subject to regular foot traffic and where the substrate is wet – wet surfaces can be sealed with one coat of ARDEX WPM 300 at a coverage rate of 3.0 square metres per litre and allowed to cure overnight.
  • It also cannot be used on glazed, glass or other totally impervious surfaces (e.g. areas pre-treated with water repellants) and where the surface temperature is below 10°C or greater than 35°C.
  • All floor areas must have adequate fall either built into the substrate or achieved with a sand/cement screed prior to application of the ARDEX WPM 001.
