App Modified Waterproofing membrane with non woven polyester Mat Reinforcement Bengal SuperMat is one of the largest selling waterproofing membranes in India. It has a special multi-layered design that gives it superior flexibility, tensile strength and resistance to nature's elements. The multilayered design consists of a 160 gsm 
Polyester Core coated on both sides with APP (Atactic Polypropylene) modified Bitumen which is finished with Polyethylene film on one side. The PE side is further coated with bitumen and then the resultant membrane is finished with Thermofusible film on both sides. This combination gives it excellent resistance to heat, ageing and ease of application.

SuperMat membranes are ideal for a wide range of waterproofing applications such as:

• Roofs
• Basements
• Tarrace Gardens

SuperMat Membranes with Mineral Top Finish SuperMat also comes with Mineral Top finish. The upper surface is coated with minerals. The bottom surface, like SuperMat, has Polyethylene. The rest of the construction is similar to SuperMat.

Both SuperMat and SuperMat MT come in thickness of 3 mm and 4 mm and in rolls of 1 m x 10 m.

• India's only Seven Layer membrane.
• Total impermeability to water and extremely resistant to Ageing and Weathering.
• Superior flexibility through a uniquely formulated coatant.

• Clean the surface thoroughly and apply Bengal Primer @ 0.3 liters per square meter.
• Always start at the low point and progress to the high point on the roof.
• The membrane should be installed perpendicular to the slope of the roof.
• Unroll the membrane and ensure proper side laps.
• Now reroll it and while standing on the unrolled portion, torch the exposed polyethylene side of the roller.
• Push the roll forward with your foot and keep moving forward. The molten bitumen and the primer will ensure good adhesion.
• The flame should be moved in shape of "L" applying about 75 percent of the heat to the roll and 25 percent to the substrate including the lap area of previously installed membrane. The flame should be moved from side to side and up the lap edge while membrane is slowly unrolled and adhered to the under lying surface.
• Heat the overlap and use round tipped towel to seal overlap.
• Excess compound should be smoothened and pressed into seam using hot trowel.
• When one end is complete, reroll the opposite end install in exactly the same manner.
• The end lap should be 100 mm and the side lap must be 75 mm.
