Bitumen Based Flashing Tapes / Strip are cold applied self- adhesive tapes with one side bitumen adhesive protected by release film and other side is re-enforced aluminium foil. Aluminium surfaced self adhesive sealing bitumen strip which bonds instantly to provide a permanent watertight seal in all climates. Flashing tape is easily applied using hand pressure and steam roller, with no requirement for special equipment for cutting, forming or fixing.
Flash Tape is used for flashing, sealing and repair against ingress of water for mobile homes, small commercial roofs, residential porches and dormers, from building, roof and gutter patching and on profile sheets. It can also be used as flashing on up stands
APPLICATION INSTRUCTION :
The application temperature should be between 5°C to 55°C. Application procedure may vary slightly depending upon site condition. The general recommended guideline for the application of the self adhesive waterproofing system is as follows:
SURFACE PREPARATION :
METHOD OF APPLICATION :
Unroll only the required length and cut the pieces to the desired shapes and size. Place the pieces of membrane on the area to be covered and check whether they match profile of the marked substrate. Peel off the release film from the self adhesive side and start unrolling the membrane and press it to the surface. Smoothen the membrane from the center to the edges with a wooden press in order to remove any entrapped air. Further more on iron roller can be used for rolling on top of the applied membrane to ensure a proper and strong adhesion of the bitumen compound with the base surface ensure a minimum of 50mm overlap.
STORAGE & SHELF LIFE :
Stored under cover, out of direct sunlight and protect from extreme temperature. In tropical climates the product must be stored in an air-condition environment. Shelf life is up to 12months when stored as per recommended storage condition.
HEALTH & SAFETY :
FLASH TAPE contain sticky compound and can stick to human skin. In such cases use a soft cloth dipped in a suitable cleaner to remove the membrane.
