duseal fg

Technical Data Sheet

USEAL FG is a high quality self adhesive sheet membrane with a reinforcement core of high quality rot proof glass fiber mat, used for a variety of waterproofing and damp-proofing applications in building and civil engineering works.The DUSEAL range belongs to the Elastoseal group of membranes produced using a special grade of bitumen modified with virgin SBS polymer. The polymer-rich mixture is used to saturate and to coat both sides of glass fiber mat to the required thickness of the membrane

USES

  • External surfaces of underground water tanks, pools, fountains, etc.
  • Floors of wet rooms in buildings, commercial and industrial complexes, etc.
  • Under roof shingles in pitched roofs and under tiles in balconies, terraces, etc.

SPECIAL FEATURES

  • High resistance to tensile stress, tear and puncture.
  • High resistance to hydraulic pressure: impermeable to water with low vapor transmission and water absorption values.
  • Wide temperature tolerances: stable in tropical climates and flexible at lower temperatures.
  • High environmental resistance: Withstands the effect of salts and other corrosive agents in soil and air.
  • Ease of application: Cold applied, with excellent adhesion to the primed horizontal and vertical surfaces in foundations, walls and floors.

USES

DUSEAL FG membranes are used in single layer or double layer applications for damp proofing and waterproofing works in building and civil engineering projects, such as

  • External surfaces of underground water tanks, pools, fountains, etc.
  • Floors of wet rooms in buildings, commercial and industrial complexes, etc.
  • Under roof shingles in pitched roofs and under tiles in balconies, terraces, etc.

METHOD OF APPLICATION

Surfaces onto which the membrane is to be applied must 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, measure and cut the membrane carefully as required before installation. Starting from one end, remove the release film and unroll the membrane, pressing firmly by hand and/or roller from the top to ensure full bond with no air pockets. Maintain a minimum of 80mm side laps and 150mm end laps between rolls and stagger the joints where possible. Press and roll laps from top to ensure a continuous Seal.
Protection: Once laid, the membrane must be protected from long-term exposure, construction abuse and backfill, preferably within 24 hours. On vertical areas Duproof protection boards DUBOARD is recommended; on horizontal surfaces a minimum 25 mm thick sand-cement screed may be used. Contact technical department of your local distributor for advice.
PACKING AND STORAGE

DUSEAL FG membranes are supplied in rolls 1m x 15m; shrink wrapped on pallets. Keep rolls upright on pallets under shade. DUSEAL FG pallets should not be stacked one over the other.

HEALTH AND SAFETY

There are no direct health hazards associated with DUSEAL membranes. Normal precautions for hot and volatile substances should be observed during application. Refer to our MSDS sheets for advice.
