Dr. Fixit TORCHSHIELD

Dr. Fixit Torchshield range of polymer modified bitumen waterproofing membranes are manufactured from rich bitumen & select polymers blended together to obtain excellent heat resistance & cold temperature flexibility. The polymer modified bitumen is then coated on to a dimensionally stable non-woven polyester/ fibre glass carrier to obtain high tensile strength, tear & puncture resistance. The Dr. Fixit Torchshield membranes are available in both SBS & APP modified versions. Features & Benefits Self finished, jointless monolithic membranes provide excellent water tight and vapour barrier system High tensile, tear & puncture resistance Can take thermal & structural stresses effectively, without any fatigue Laid quickly & easily; safe & environment friendly Do not undergo early ageing, thus provide long life durable membrane Easy melting & fixing, thus saving on usage of expensive gases Available in 3, & 4 mm thickness APP / SBS modified membrane rolls Technical Information Size : 1 x 10 meter Thickness : 3 mm to 4 mm Softening point : : 100-150°C Penetration at 25°C dmm : 15-40 dmm Tensile strength (L/T)N/5cm : 700/550 Elongation at break (L/T)% : 40/50 Tear Resistance (L/T)N : 140/160 Water absorption % : < 0.15 Packing Range of 3 & 4 mm membranes in Polyester or fibre glass base in 1 mtrs X 10 mtrs rolls AREA OF APPLICATION: G.I. & AC Sheet Roofs Industrial Roofs Swimming Pools Sloped Roofs Flat Roofs Parking area Bridges & Tunnels Foundation of Retaining Wall Basements Method of Application This application procedure is a standard guideline for using the 3 & 4 mm membranes only, which may slightly vary upon the site conditions & different application areas. Clean & remove dust, dirt, loose particles and unsound substrate. Make surface smooth, even & free from local depressions with polymer modified mortar Apply primer coat with solvent based bitumen primer on cleaned & leveled surface @ 3-5 sq. mtr / ltr Unroll the Dr. Fixit Torchshield Roll after application of primer Align the Dr. Fixit Torchshield Roll correctly & re-roll it in alignment before torching Use gas burner to heat substrate & underside to softening points. When the embossing disappears, roll forward & press firmly against substrate to bond from the lower end towards the higher end Keep overlap margin for minimum 100 mm Heat both the overlaps & use round tipped trowel to seal overlap. Excess compound should be smoothened & pressed into seam using hot trowel All angles & abutments upstands should be sealed with extra care to ensure perfect bondage. Seal the edges well into grooves & protect with a Polysulphide sealant Dr. Fixit Torchshield applied all over the terrace and finished with aluminum paint for non foot traffic area. For foot traffic area, overlay with concrete screed mortar. Clean & remove dust, dirt, loose particles and unsound substrate Apply primer coat with solvent based bitumen primer Unroll the DR. FIXIT TORCHSHIELD roll Align the Dr. Fixit Torchshield Roll Use gas burner to heat substrate & underside to softening points Keep overlap margin for minimum 100 mm Heat both the overlaps & use round tipped trowel to seal overlap Seal the edges well and protect with a Polysulphide sealant Dr. Fixit Torchshield applied all over the terrace top Precautions & Limitations Any naked flame should be kept well away from gas cylinders. When ignited the Dr. Fixit Torchshield should be watched at all times. The torch should not be rested on finished roofing. Extreme care should be taken when working near combustible materials or items which might be scorched by the gas flame. Not to be applied in extreme cold climatic conditions (below 50C) Not to be applied on damp/wet areas & areas subject to moisture restoration. Do not overheat the Dr. Fixit Torchshield membrane i.e. avoid heating when it starts smoking. The bleeding should be at least 10 to 15 mm on the edges and should be finished with hot trowel The moisture content on the surface should not exceed 6% to overlay the membrane Use of a Solvent Bitumen based primer is a must. For better result, use the Dr. Fixit Primer.
