ARDEX WPM 185
(Shelterbit Mineral Membrane) 4.5kg/m2 mineral coated APP bitumen membrane Excellent resistance to atmospheric agents Resistant to chemical attacks High puncture resistance
ARDEX WPM 185 (Shelterbit Mineral) is an A.P.P. (Atactic Polypropylene) Plastomeric type modified bitumen membrane, consisting of a specially formulated bituminous compound of distilled asphalt modified with selected high grade visco-elastic polymers and reinforced with a combined reinforcement (Polyester and Fibreglass). ARDEX WPM 185 is coated with a slate mineral granule topping, while the bottom surface is embossed and protected by a heat sensitive polythene film. This type of finish for the lower surface has been chosen for two specific purposes:
1. To act as a temperature gauge during application. When the film melts it shows that the compound is at the correct temperature.
2. The embossing is to allow the gases to rapidly escape when heated to its correct installation temperature avoiding possible problems of bubbling and blistering.
Features and Benefits
Positive vapour barrier.
Excellent resistance to atmospheric agents.
Cold flexibility 5 oC.
Resistant to chemical attacks.
Withstand thermal shocks.
Heat welded laps provide homogenous joint.
High puncture resistance.
ARDEX WPM 185 is used as a cap layer in exposed membrane systems (allowing light foot traffic for maintenance). ARDEX WPM 185 is available in slate grey
The application of ARDEX WPM 185 should be carried out by an accredited applicator. Installation shall be strictly in accordance with the manufacturerâ€™s recommendations. All surfaces to which the ARDEX Shelterbit systems are installed must be properly prepared prior to installation. All surfaces must be clean, dry, smooth and free of sharp edges, fines, loose or foreign materials, oil, grease and other materials which may damage the membrane. New concrete must be cured a minimum of 28 days prior to the installation.
ARDEX WPM 185
Apply to all surfaces one coat of ARDEX WPM 240 Bituminous Primer at a coverage rate of 5 square metres per litre and allow to dry thoroughly.
Note: when used as an intermediate layer over a base sheet, primer is not required.
A layer of ARDEX WPM 185 (Shelterbit Mineral) shall be installed over all surfaces to be treated by LPG torch application techniques by an ARDEX accredited applicator. The ARDEX WPM 185 (Shelterbit Mineral) must be fully bonded with side laps of 7.5cm and end laps of 10cm. The membrane must be detailed in accordance with ARDEX recommendations. Overlaps shall be sealed by torch.
ARDEX WPM 185 is non-hazardous; non-dangerous goods. However during installation exercise caution when working with open flame. Examine all surfaces to which the flame has been applied for smouldering or burning conditions. Do not use open flame on or near highly combustible materials. Follow all local fire codes.
All rolls of ARDEX WPM 185 should be stored in a covered area protected against sunlight and UV radiation. Rolls should be stored in a vertical position on a smooth floor so as not to damage the edges.
Roll size: 1m x 8m
Roll weight: Approximately 36kg
