TIMBER LAYING SURFACE Sheets of bituminised paper or ROLLBASE should be fixed to timber surfaces with large head nails to protect the wood from the torch-flame. Then the membrane should be bonded using the total adherence principle. LAYING ON TOP OF OLD APPLICATIONS If the condition of the old application allows it to be retained, it can be used as a substrate Perished and weakened areas must be removed and blisters must be flattened. Spread a layer of INDEVER primer before the application of Index membrane. LAYING ON NON-HEAT SENSITIVE PANELS Two possibilities exist: torching directly onto the upper surface of pretreated panels made on purpose for this type of application; alternatively, applying it on top of bituminised glass-fibers felt stuck to the panel with hot blown bitumen ALIGNMENT OF THE SHEETS Unroll the sheet and align it by overlapping the edge on the nearest sheet. Then partially roll it up again from both ends and start the flame-bonding process. Take care to do not create points where 4 layers are coming together, in other words do not align the head of the rolls or do not place two layers exactly one above the other. Page n° 12 out of 24
UNROLLING SHEETS AT LOW TEMPERATURES When temperatures are low, do not bang the rolls or unroll them in a way that may damage the membrane. Unroll them with care and without kicking them. MEMBRANE SURFACES The underside of the sheet is the surface to be treated. It is embossed with squares and lined with a thin film of FLAMINA. When heated, the FLAMINA film melts to indicate when the material is ready for bonding. The upper side of the membrane is covered with TEXFLAMINA (“non woven” PP) This helps to ensure the wrapping detaches even at high temperatures. TORCHING Polymer-bitumen waterproofing membranes bond with the application of heat and do not require materials such as solvents, adhesives etc. Use of a propane gas burner is used to heat the sheet to make it adhesive. As the material is heated, the Flamina film retracts, the upper side blackens until it takes on a shiny appearance, the embossing flattens down, the surface becomes shiny and the membrane is ready to be bonded to the support and overlaps. The INDEX trademark is printed in white on the flamina film, which disappears to indicate retraction has reached the correct point. Flame heating causes the film to retract and the embossed pattern to flatten; further heating can cause the polyester reinforcement to be damaged, which melts at 260°C, and causes shrinkage, waving, curling and, in the worst case, will burn holes in the material. On the other hand, insufficient heating will not bond the material adequately to the surface, between layers or on overlaps. When the material is applied on insulation board with a slope > 20% is necessary to provide a mechanical fixation for the head of the rolls, if, there is no insulation board is possible to reach a slope of 40% without having a mechanical fixation. Without insulation is possible to reach slope higher then 40%. OVERLAPS Overlaps have to be always welded by torching and pressing down, they have to be 10 cm wide longitudinally (side laps) and 15 for the roll’s heads cm (end laps). SEALING OF OVERLAPS, WHAT NOT TO DO Sealing of overlaps with a trowel, spatula or other tools has been shown to do more harm than good. First, it nicks and therefore weakens the membrane reinforcement, and often the upper protective layer is removed and the reinforcement is left exposed. It often happens that operators bond only 1 or 2 cm. of the overlap hoping that sealing of overlaps will create an adequate seal but they do not realize that such little bonding does not create enough adhesion for the overlap to be sealed. In the end, time is lost by having to rework the overlap. Page n° 13 out of 24
