Bituminous SBS modified membrane reinforced with a heavy non-woven polyester felt. Finished in a quick-melt thermofusible film. Designed for torch-applied applications and Safe2Torch details using hot-air.

Instruction for Use



  • Substrate should be dry and clean from grease, dirt, debris or any other contaminants.
  • Where applicable, prime surface with CURIDAN or BITUMEN PRIMER+ in accordance with DANOSA instructions and allow to dry.
  • For field applications: 
  • Roll the membrane into position, allowing for 80mm side overlaps and100mm head overlaps and cut to length. All overlaps and cross joints should be staggered by a minimum of 300mm.
  • Using a length of 100mm ø pipe (cut fractionally short of roll width) as an insert tube, roll back the membrane for a portion of the length (approximately 50%).Heat activate the membrane by torching in a vee area between the roll and substrate.
  • Roll can be pushed forward by foot or by other suitable equipment. Apply downwards pressure when moving the roll to extrude a molten bead of bitumen from edges.
    • 4. For detail applications
  • Place the membrane into position, allowing for 80mm side overlaps and100mm head overlaps and cut to length ensuring all overlaps and cross joints are staggered by a minimum of 300mm.
  • Heat activate the membrane by torching between the membrane and substrate.
  • Apply pressure and consolidate the bond to the substrate, ensuring a molten bead of bitumen is extruded from the edges.
  • Where specified, POLYDAN 180-40/P ELAST head laps should be mechanically fastened with DANOSA SUREFAST tubes or pressure plates and the appropriate mechanical fasteners at a minimum of 200mm centres in accordance with DANOSA instructions.


    • Where falls apply, membrane rolls should be rolled up the slope so that water drains over and not into membrane overlaps.

    Maintenance Recommendations

    • Please refer to DANOSA UK Technical Statement ‘Flat Roof Waterproofing – Cleaning and Maintenance Recommendations’
