NCL ULTRA-TORCH XP Waterproofing Membranes is a quality APP (attactic polypropylene) modified bituminous membrane
designed to meet the needs of the construction industry. NCL ULTRA-TORCH XP is manufactured with non-woven polyester
reinforcements that are impregnated and coated with a mixture of APP polymer modified bitumen compound. Upper surface
can be finished in sand, mineral slate or polyethylene film.
NCL ULTRA-TORCH XP exhibits excellent properties of resistance to atmospheric agents and to aging. It ensures shape stability
at high temperatures and facilitates the ease of application and adhesion. NCL ULTRA-TORCH XP range include 3mm, 3.5mm
and 4mm with different surface finish.
AREAS OF APPLICATION
• Trafficable Roofs
• Roof Gardens
• Concrete Roofs
• Balconies and Terraces
• Decks, Basement and Landscaped areas
FEATURES & ADVANTAGES
• Positive barriers to water and vapour.
• Good UV light resistance (Mineral Finish Only)
• Withstand thermal shocks
• High flexibility at low temperature
• Good elastic memory
• Easy application
Supplied polyethylene wrapped on pallets. Please refer to storage for individual roll storage and handling.
10% for overlaps and 4% for normal detailing wastage.
NCL ULTRA-TORCH XP is recommended to store in cool dry place. Membrane rolls should be stored preferably on pallets in an
upright position and protected from excessive heat and moisture. Membranes and primers have a shelf life of 12 months.
On new roof or landscaped area, a screed made of normal mortar should be laid with thickness 20 – 50mm with slope
maximum 5%. Thoroughly inspect existing roof and make sure it is structurally sound, smooth before priming and laying of
NCL ULTRA-TORCH XP.
Bituminous primer must be applied between membrane and substrate. Substrate need to be cleaned, dry and smooth and
estimate consumption will be approximately 0.3 litre per sq. m. per coat. Two coats may be needed when applying to very
porous substrate condition.
Allow primer’s drying time of 2 – 4 hours, unroll the NCL ULTRA-TORCH XP and place in the position where it has to be torched
at the lower surface with propane gas, NCL ULTRA-TORCH XP will melt and subsequently adhere to the primed surface.
Membrane should overlap each other by at least 10 cm at the side laps and 15cm at the end laps. Inspection of lap joints must be
carried out to ensure total adhesion. Smooth out all seams with a rounded trowel. All mineral finished membrane application
where laps occur over the slate finished have the slate topping removed to a width of 10cm to allow the overlap to be fully
bonded to the bitumen.
For general cleaning use ethyl methyl ketone blended cleaner. Do not use solvent on skin use Clean Towels.
MEMBRANE TESTING & REPAIR
It is recommended that a water test, where ever possible, be carried out over a 24 hour period. All leaks should be marked and
the membranes repaired when cleaned and dry. Any damaged areas must be repaired with a patch of NCL ULTRA-TORCH XP
with a minimum overlap of 10cms from any edge.
The membranes should be protected after installation from damage with protective board such as water resistance particle
board, plywood, fire –cement or any other proprietary protective board should be adhered with protective board type.
