Packing
Range of 1.5, 2, 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. For application method for 1.5 & 2.0 mm, consult Dr. Fixit
- 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.

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.
