ARDEX WPM 179 - Single Component Rubber Waterproofing Membrane
Quick Drying - designed for fast track installations
Used in conjunction with WPM 172 Rapid Cure Membrane
Chemical Resistance - for a wide range of chemicals
Water Based - safe to use, low in VOC & odour
ARDEX WPM 179 is a one component liquid applied, latex modified, bituminous elastomeric waterproofing membrane. When cured it forms a permanently flexible waterproof lining to most building surfaces. ARDEX WPM 179 is predominately used as a patching or repair membrane for use in conjunction with ARDEX WPM 172 Rapid Cure Rubber Waterproofing Membrane. ARDEX WPM 179 is water based, has almost no odour and is safe to use.
Easily applied: single pack, high build, long pot life.
Excellent adhesion to substrates.
High elongation - excellent crack bridging capabilities.
Retains flexibility at low temperatures.
Resists ponding water (once fully cured).
Water based - environmentally friendly and safe to use,
Excellent Chemical Resistance properties.
Conforms to AS4654.2 - 2009 waterproof membranes for exterior use.
Concrete structures and concrete formwork.
Cement/sand screeds/renders - cured for a min 28 days and 14 days respectively. Alternatively apply a barrier coat of ARDEX WPM 300 (HydrEpoxy 300) as a barrier coating to fresh or wet substrates.
Masonry and concrete blocks - voids filled, sharp edges and protrusions should be removed to give a flush finish.
Below ground tanking, basements and retaining walls (not negative hydrostatic situations)
Bridge decks and concrete structures
Concrete protection from chemicals and water ingress
Corrosion protection of metal roofs and structures
Waterproof liners for sewage and containment ponds, dams and tanks
Underground Structures / Tunnel lining
Basic Application Instructions
The surface to be coated should be clean, sound and free from oils, greases and flaking paint. New concrete should be cured for 28 days (or a barrier coat of ARDEX WPM 300 (HydrEpoxy 300) applied) prior to application of membrane and the surface pores must be open. All cracks or holes exceeding 2mm are to be repaired before application commences. Surface may be slightly damp but must be free from seeping moisture. Surface to which the coating is to be applied should be smooth with no sharp edges to ensure a uniform film thickness is achieved.
ARDEX WPM 179 is selfpriming on most surfaces and a primer is therefore not necessary. Wet or freshly placed concrete surfaces should be sealed with Ardex WPM 300 (HydrEpoxy 300) in one coat at a coverage rate of 3.0 square metres per litre. Porous substrates such as aerated concrete should be primed with Ardex WPM 179 Single Component Rubber Waterproof Membrane mixed with 50% water.
ARDEX WPM 179 can be applied by brush or trowel to the substrate over the entire area to be repaired or waterproofed. Allow 24 hours between coats for ARDEX WPM 179 unless a reinforcement material is used between coats. In this case, the second coat can be applied immediately after the mat has been installed in the first coat. The membrane is fully dry in 24 hours, after which should be protected with ARDEX protection boards or geotextile fabric coated drainage cell.
Coverage and thickness
As a patching/repair membrane one coat of ARDEX WPM 179 will cover approximately 15m2 (dry film thickness of 0.6mm). If two coats are required ARDEX WPM 179 will cover approximately 78m2 (dry film thickness of 1.0mm).
Detailing of petrusions and expansion joints
ARDEX WPM 179 can be directly applied onto penetrating PVC pipes, rebars and metal fixings providing a seamless waterproofing layer. Expansion joints and corners should be covered using ARDEX Waterproofing Detail Tape.
ARDEX WPM 179 is fully dry in 2448 hours at 25oC and 50% relative humidity. After which it should be protected with ARDEX protection boards or geotextile coated drainage cell.
ARDEX WPM 179 is nonhazardous and nondangerous. Do not breathe gas/fumes/vapour/spray. Wear eye/face protection. Use only in well ventilated areas. Keep container tightly closed and in a well ventilated place. In case of contact with eyes, rinse with plenty of water. In event of irritation seek medical advice.
ADDITIONAL INFORMATION IS LISTED IN THE MATERIAL SAFETY DATA SHEET.
ARDEX WPM 179 is sold in 15kg pails. Shelf life is 12 months when stored in the original unopened container, in a dry place at 25oC. Do not store in direct sunlight. Replace lid tightly after use.
Clean up and disposal
Clean all equipment in fresh water immediately after use. Remove cured material with mineral turpentine or white spirits. Dispose of containers in compliance with all relevant local authorities, state, and federal regulations.
