Such a product is Autotene Base/P as supplied by Parchem. Areas shall be prepared and the membrane shall be applied in accordance with the currant technical data sheet. All materials used in conjunction with the Autotene Base/P membrane shall be approved by Parchem. Application of the membrane shall be carried out by a competent applicator, well trained in the application of modified bitumen membrane systems. For further detailed specifications information refer to the appropriate Waterproofing Specification available from your local Parchem sales office. Application Instructions Surface preparation All surfaces to which Autotene Base/P is to be applied must be smooth, free from contaminants and loose material. Insulation panels shall be fixed to the substrate as per manufacturers’ recommendations. All existing membranes shall have any blisters or wrinkles cut and repaired all as required. Rough or uneven surfaces must be faired up before commencing application. Contact Parchem for suitable fairing products. Priming Priming of the surface generally is not required including polystyrene foam insulation; however priming of other very porous surfaces may be required. Where required the surface shall be primed with Emer-Proof Self Adhesive Primer at the rate of 6-8m² litre. The coverage rate for the primer will vary depending on the porosity of the surface being treated. Allow the primer to dry for at least 15 minutes at temperatures of 25°C and above, and up to 60 minutes when ambient temperatures are approaching 5°C. Priming should only be carried out on surfaces which will be covered with Autotene Base/P on the same day. Application Planning the installation of the membrane is important to ensure joints occur in suitable locations. Autotene Base/P must be laid to allow side laps of 60 mm and end laps of 150 mm. Application of the membrane should always start from the lowest point on a surface to ensure laps are self-flashing. Apply suitable lengths of Autotene Base/P membrane by first carefully aligning the roll, roll up the membrane and remove the first 300 mm of the release paper and apply to the surface. Pull the remainder of the release paper while unrolling the roll, pressing the adhesive under side of the membrane to the surface. The heat from the following layer being torch bonded will activate and maximise adhesion to surface including the over lap area. Index® Autotene Base/P
