To order specify thickness e.g. DULAS AG 4 mm for aluminum finish, glass reinforcement and 4 mm thick sheet membrane.
METHOD OF APPLICATION
Surfaces onto which the membrane is to be applied must be sound, clean and dry. Dust, loose material and protrusions must be removed and cracks, holes etc made good.
Priming: Apply one coat of Duprime solvent based bituminous primer to all surfaces at 5-6 m²/lit
and allow to dry. Primed surfaces must be covered within the same day. If left exposed for longer periods, clean and re-prime before applying the membrane.
Membrane Application: Position the rolls carefully with the correct orientation before the torching operation begins. Heat the lower surface of the rolls with a propane gas torch and unroll as the bitumen begins to melt. Maintain minimum 100 mm side laps and 150 mm end laps between rolls, staggering the joints where possible. All seams must be heat sealed from the top to ensure watertight laps.
PACKING AND STORAGE
DULAS AGmembranes are supplied in rolls of 1m x 10m, shrink wrapped on pallets. Rolls must be kept upright on pallets under. DULAS AG pallets should not be stacked one over the other.
HEALTH AND SAFETY
There are no direct health hazards associated with DULAS AG membranes. Normal precautions for hot and volatile substances should be observed during application. Refer to our MSDS sheets for advice.
