Ardex WPM 908 :


ARDEX WPM 908 - Water Based Acrylic Trafficable Membrane  

 

Abrasion resistant - excellent slip resistance properties

Single component - ready to use, no mixing required

UV resistant - suitable for exposed applications

Water based - safe to use, low odour

Green Star - meets the benchmark for VOC credit in the Green Building Council of Australia's Rating Tools  

 

Description  

 

ARDEX WPM 908 is a water based single part acrylic trafficable waterproof membrane. It has specifically been developed for use as a hard wearing trafficable membrane on various substrates. ARDEX WPM 908 has been formulated to give anti-slip properties without the use of additional broadcast sand or fillers.  

 

Features/Benefits  

 

Waterbased - safe to use, low odour

Abrasion resistant- excellent slip resistance properties

Single component- ready to use, no mixing required

UV resistant - suitable for exposed applications

Green Star - meets the benchmark for VOC credit in the Green Building Council of Australia's Rating Tools  

 

Range of Applications  

 

Pedestrian traffic podiums

Terraces

Balconies

Roof decks

Plant and mechanical room floors

Swimming pool surrounds

Trafficable box gutters

Surface Preparation  

 

Concrete - the preferred surface texture for concrete floors in preparation for the application of ARDEX products is a wood float finish. Steel trowel finished concrete must be roughened mechanically as necessary to remove laitance and provide a good key for product application. All surfaces must be dry and cleaned free from dirt, grease, oil, curing compounds, loose particulates and other surface contaminants.  

Existing membranes or coatings on concrete - all existing membranes, adhesives and other surface coatings shall be removed by mechanical means and the surface treated to open the pores. All surfaces shall then be cleaned free from all loosely bound materials and all other surface contaminants and allowed to dry thoroughly.  

Compressed Fibre Cement sheets must be fixed strictly in accordance with the manufacturer's instructions. Mechanical fixings such as screws shall be countersunk, filled and sanded to a smooth substrate surface finish. All surfaces shall then be sanded to a smooth to plane finish and vacuumed to remove all loose particles. All surfaces should be dry, clean, and free of dust, grease and all loose contaminating materials. Joints between sheets and perimeter joints should be sealed with a neutral cure silicone and a 30mm bondbreaker tape (PVC duct tape or masking tape) shall be installed equidistantly across each joint.  

 

Substrates  

 

Concrete  

Cured for minimum 28 days, wet concrete should be allowed to dry thoroughly or sealed with one coat of ARDEX WPM 300 at coverage rate of 3.0m2 per litre.  

Renders and screeds  

Cured for min 7 days. Wet render should be allowed to dry thoroughly or sealed with one coat of WPM 300 at coverage rate of 3.0m2 per litre and allowed to cure overnight.  

Compressed fibre cement sheets  

Wet area grades only.  

 

Primer  

 

Prepared substrates must be primed with ARDEX WPM 300 (HydrEpoxy) prior to the application of ARDEX WPM 908 Trafficable Membrane.  

 

Typical Applications

 

External decks and floors, rooftops (new and existing), podiums, parapets.

External timber decks should be waterproofed with ARDEX Butynol membrane.  

Application  

Apply ARDEX WPM 908 with a brush or paint roller. Stir ARDEX WPM 908 thoroughly prior to each application. Apply at a wet film thickness rate of 400μm per coat (three coat system) to ensure full coverage with brush or roller. Apply ARDEX WPM 908 at a minimum of three coats ensuring a uniform coverage is achieved at an approximate wet film thickness of 0.4mm per coat to achieve an overall dry film thickness of 0.6mm. Anti slip properties may be enhanced on application by using a textured roller. ARDEX WPM 908 has been formulated to provide anti-slip properties. For superior anti slip properties, use of alumina grit is recommended. This should be broadcast over the first coat of ARDEX WPM 300 prior to application of ARDEX WPM 908 Trafficable Membrane.  

 

Coverage Guide

1) Prime Coat        ARDEX WPM 300    (WFT)        0.3mm

2) First Coat         ARDEX WPM 908    (WFT)        0.4mm

3) Second Coat     ARDEX WPM 908    (WFT)        0.4mm

4) Third Coat        ARDEX WPM 908    (WFT)        0.4mm

Coverage  

Approximately 12.5 m2 per pail (three coat system).  

 

Drying Time  

Recoat time is 2 - 4 hours in between first and second coats. Drying time on flat surfaces under standard conditions is around 4 hours. However, dry through time will be slowest in areas where ARDEX WPM 908 is applied over silicone bond breaker, or is reinforced. Make sure these areas are dry. In some cases, this can vary from 24 hours to 48 hours. Full cure of the product is 3 days after application at 23oC. Drying times will vary depending on humidity, surface temperature and porosity of substrates.  

 

Packaging/Storage  

15L (17.3kg) pail, 12 months when stored in the original unopened packaging in a dry place at 23oC.  

Clean up and Disposal  

Wash hands, brushes, rollers, etc, with water while the membrane is still fresh. Remove cured material with mineral turpentine. Remove any food or drink stains immediately with warm water and a mild household detergent. Dispose of containers in compliance with all relevant local, state, and federal regulations.  

 

Precautions  

All surfaces must be structurally sound, dry and free from all surface contaminants.  

DO NOT USE ARDEX WPM 908 UNDER THE FOLLOWING CONDITIONS

Areas subject to negative hydrostatic pressure or rising damp.

Wet substrates or green screeds/concrete - need to be sealed with one coat ARDEX WPM 300 as described earlier.

Surface temperatures below 10oC or greater than 35oC
