    ADDITIONAL INFORMATION

    ARDEX WPM 444 (Shelterbit Phoenix Star) is an APP (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 444 (Shelterbit Phoenix Star) is certified in Great Britain with BBA No 99/3586/C and in Italy with Technical Agreement I.T.C. 591/03.

    ARDEX WPM 444 (Shelterbit Phoenix Star) is coated with either a sanded or talc top surface finish, 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.

    Installation

    The application of ARDEX WPM 444 (Shelterbit Phoenix Star) should be carried out by an approved Applicator.

    Installation shall be strictly in accordance with the manufacturer’s recommendations.

    Acceptable substrates to which ARDEX WPM 444 (Shelterbit Phoenix Star) is to be installed must be properly prepared prior to membrane installation.

    All surfaces must be dry, clean, smooth, free of sharp edges, loose or foreign materials, oil, grease and other materials which may damage the membrane.

    Prior to the application of ARDEX WPM 444 (Shelterbit Phoenix Star) base substrate surfaces should be primed with ARDEX WPM 240 (Shelter Primer). Coverage of primer will depend on the porosity of the substrate.

    ARDEX WPM 444 (Shelterbit Phoenix Star) is normally fully bonded to the prepared substrate with side laps of 100mm and end laps of 150mm. Overlaps shall be sealed by torch.

    ARDEX WPM 444 (Shelterbit Phoenix Star) may be used in various combinations to produce a variety of specifications tailored to suit the individual waterproofing need.

    ARDEX WPM 444 (Shelterbit Phoenix Star) is used as a single layer membrane system which is normally installed prior to the installation of toppings, road base or hot melt asphalt or bitumen.

    Application of toppings may be applied on completion. Road base may be installed directly to the membrane without an extra protection layer.

    The asphalt should be applied as soon as possible after the ARDEX WPM 444 (Shelterbit Phoenix Star) membrane has been installed. ARDEX recommend applying a minimum 50mm compacted overlay for carpark areas. The topping should be applied in two layers at a temperature of between 120-150°C.

    The exact specification will depend on functional and economic requirements. Advice should be sought for suitable specification from ARDEX .
