Swastik Bitumen Shield is a APP Modified glassfiber reinforced bituminous Membrane sheet for excellent waterproofing application. It exhibits superior tensile strength, tear strength, puncture resistance and dimensional stability. The torch side of the membrane is covered with polyethylene film for protection of the membrane. Polyethylene Film on top and bottom side of sheet
Can Apply Swastik Bitumen Shield APP Membrane in horizontal and vertical applications for protection of various substrates like concrete, masonry, GI, aluminum, wood etc. in wide range of uses:
Polyethylene protection film for protection, it consist of a center core of non woven Fiber glass mat for extra mechanical strength. The center core is protected on both sides with Polymeric Asphaltic mix, which has high penetration, high heat resistance and high softening point. With high tensile strength, the membrane is still extremely flexible and pliable to adapt to contours. For this reason this membrane makes an ideal waterproofer.

Application of Swastik Bitumen Shield APP Membrane is fast and easy. Smooth surface with minimum slope is required to apply the membrane. The surface is first cleaned to eliminate all sharp projections. Suitable Swastik OB Primer / Swastik Blown Bitumen is then coated on the surface. Swastik Bitumen Shield APP Membrane is to be unrolled over the surface with torch application (with overlaps of 10cm) and bonded to the substrate. The overlaps are to be sealed by flame torch. Special care is to be taken at singularities such as drains, expansion joints, etc.
Swastik Bitumen Shield APP Membrane can be topped with topping such as cement screed or tiles on accessible roofs with a chicken wire mesh reinforcement. Inaccessible roofs can be topped with a layer of Swastik Blown Bitumen and Aluminium Paint
