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
To act as a temperature gauge during application. When the film melts it shows
that the compound is at the correct temperature.
The embossing is to allow the gases to rapidly escape when heated to its
correct installation temperature avoiding possible problems of bubbling and
resistance to atmospheric agents.

welded laps provide homogenous joint.
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
application of ARDEX WPM 185 should be carried out by an accredited applicator.
Installation shall be strictly in accordance with the manufacturer’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.
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.
when used as an intermediate layer over a base sheet, primer is not required.
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

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
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.
