Instruction For Use

Application Process

  • Surface Cleaning

    Clean the surface carefully to make it smooth and free of odd objects.

  • Primer Coating

    The groundwork surface must be coated with a primer, 03-0.5 kg per meter,using brush or roller. Let it dry up.

  • Unroll Membrane

    Unroll the Hydrostop membrane half-way and align the side laps. Single plasticized layer for bonded bituminous system. Start laying at the lowest point of the roof and progress to the highest point.

  • Overlap Measurement

    Side overlaps must be at least 8 cm. End overlaps must be at least 10 cm.

  • Re-roll Alignment

    Re-roll in alignment before torching.

  • Torching

    The Hydrostop membrane is bonded by using gas torch. Use flame to heat substrate & underside to softening points. When the printed film nearly disappears, roll forward & press firmly to bond.

  • Flame to be applied

    Flame to be applied in L movement where 60% of heat is applied to roll and 40% to the substrate. Heat both laps & use round tipped hot trowel to seal overlap.

  • Excess compound

    Excess compound should be smoothened & pressed into seam using hot trowel.

  • Double Layer

    Double plasticized layer for bonded bituminous system.

  • Bottom Layer

    Top Hydrostop membrane side overlap must be staggered in comparison to the bottom layer to improve quality solution.

  • Re-roll Alignment

    Re-roll in alignment before torching.

  • Using Gas Torch

    Both Hydropstop membranes are bonded by using gas torch.

  • All Angels Sealed

    All angels & abutments upstands should be sealed with extra care to ensure perfect bondage.

  • Double layer system

    Double layer self-protected adhered bituminous system.

  • Mineral Finishing

    Side overlap is defined in mineral finishing Hydrostop membrane.

  • End Lap

    Align the end lap.

  • Mineral Finished

    Mineral must be removed in bottom Hydropstop membrane where end overlap is done in the mineral finished membrane.

  • All Angles Sealed

    All angles & abutments upstand should be sealed with extra care to ensure perfect bondage.
