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.
