      How to Use

      SURFACE PREPARATION & PRIMING

      The surface shall be cleaned thoroughly of all contaminants like dust, traces of curing compound, oil and grease. All surface imperfections, protrusions, structurally unsound and friable concrete must be removed and repaired.
      Apply POLYPRIME SB* (Solvent based primer) @4-6 m²/lt to a clean, smooth and dry surface by brush, roller or spray. Allow the primer to dry prior to the application of the membrane. The primer promotes the adhesion between the membrane and the concrete surface.

      ALIGNMENT & TORCHING

      Start the installation of all membrane plies from the low point or drains, so that the flow of water is over or parallel to the plies, but never against the laps. All overlaps at the membrane seams shall be installed so as to have "up" slope laps over "down" slope laps. Begin membrane application by unrolling the roll of BITUPLUS E 5180 membrane and aligning the side laps. Side overlaps should be a minimum of 100 mm and the end overlaps 150mm.
      BITUPLUS E 5180 membrane is installed by using a cylinder fed propane gas torch. Use of hand-held roofing torch is recommended as it affords a good control. Begin torching the embossed polyethylene side of the rolled portion of the membrane. As the membrane is heated the embossing starts to melt away exposing a shiny bitumen surface. Roll forward the membrane and press firmly with the boot or roller against the substrate to bond well. The propane flame should be moved from side to side and up the lap edge while the membrane is slowly unrolled and adhered to the underlying surface.

      3.PROTECTION

      BITUPLUS E 5180 should be protected from getting damaged due to the ongoing site activities and during backfilling. Membranes laid on horizontal surfaces can be protected either by a cement sand screed (50mm thick) or by an asphaltic protection board (BITUBOARD)*. On vertical surfaces the membrane has to be protected with BITUBOARD. BITUBOARD can be fixed on the membrane by torching the underside of the board, or with a double sided bitumen adhesive tape (BITUTAPE TS)*.

      Frequently asked questions

      It is recommended using solvent based bitumen primer conforming to ASTM D 41

      Yes. It msut be protected from damages that may happen during the site activities.

      No. It is not necessary to use bonding agents or twin sided tape for fixing on torch applied membranes. It can be applied by torching.
