      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 unsoundand friable concrete must be removed and repaired with a suitable Polycrete* concrete repair mortar.
      Apply Polyprime SB* (solvent based primer) @ 4- 6 m²/L to a clean smooth and dry surface by brush, roller or spray.
      Allow the primer to dry prior to the application of the membrane. As the viscosity of the primer is low, it easily penetrates into the concrete pores which promotes the adhesion between the membrane and the concrete surface.
      In addition to that the primer also acts as a binder for the dust which gets accumulated on the concrete surface even after cleaning.

      ALIGNMENT & APPLICATION

      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 Bitustick XL membrane and aligning the side laps.
      Peel off the release film from the self adhesive side and start unrolling the membrane and press it to the surface. Smoothen the membrane from the center to the edges with a wooden press in order to remove entrapped air. Furthermore, an iron roller shall be used for rolling on top of the applied membrane to ensure a proper and strong adhesion of the bitumen compound with the base surface. Side overlaps shall be a minimum of 50mm on the selvedge and end overlaps 100mm.

      PROTECTION

      The membrane shall be protected immediately after
      application from damage, due to ongoing site activities or
      from sharp aggregates during backfilling by a tough, weather,
      warp and rot proof asphaltic protection board (Bituboard /
      Bitustick R300/ Bitustick R400)*. Alternatively, on horizontal
      areas the membrane can also be protected by laying a
      cement sand screed (50mm). Bituboard can be fixed with a
      double sided adhesive bitumen tape (Bitutape TS)*.
