Rough concrete must be ‘faired up’ before commencing application. Contact Parchem for suitable fairing products. Priming Index Bitumen Primer is normally applied to all concrete and masonry substrates. Index Bitumen Primer should be applied at a rate of approximately 0.13 L/m2 to surfaces which Argo P will be applied. Coverage rate for primer will vary depending on porosity of surface being treated. Allow the primer to dry for at least 1 hour at temperatures 25°C and above, until the primed surface is tack free. At lower temperatures allow additional drying time to ensure a tack free surface. Priming should only be carried out on surfaces that will be covered with the membrane on the same day. Application Planning the installation of the membrane is important to ensure joins occur in suitable locations. Argo P membrane must be laid to allow side laps of 100 mm and end laps of 150 mm. If membrane is to be spot bonded, full bonding must occur for 1 m each side of end laps. Application of membrane is by torch bonding using a suitable gas torch. The membrane is applied with surface protected by the Flamina facing down towards substrate, during the application of the gas flame the Flamina will melt away. Bonding is achieved by slowly unrolling the membrane whilst directing flame at the underside of roll and melting the bitumen by moving the torch from left to right. Side laps must be welded with care. Correct welding will show a 4 - 8 mm wide continuous bead of bitumen along the lap. Side laps should be 100 mm wide. Attention should be given to end laps ensuring complete adhesion allowing 150 mm overlaps. On completion of the membrane installation all exposed perimeter edges must be mechanically fixed or terminated under a flashing. INDEX 480 Protection Whilst the Argo P membrane is based on an APP modified bitumen which is resistant to UV, it is not recommended for long-term exposure without some form of protective topping medium. Fidia Mineral or Testudo Mineral should be used as a cap or weathering sheet for use in non-traffic / maintenance traffic areas. Where the membrane is to be back filled, such as with basement applications, the Argo P should be protected from mechanical damage with the Emer-Proof Drain V drainage/ protection system also available from Parchem. Limitations New concrete substrates should be allowed to cure for a minimum of 28 days prior to the installation.
