BITUFLAME – ROOFING FELT |WATERPROOFING MEMBRANE |ARIZONA GMCI.

BITUFLAME P 4180, P 4200 & P 4260

Bituflame range of modified bitumen waterproofing membranes are manufactured from a rich mixture of bitumen, APP (Atactic Polypropylene) and selected polymers blended together to obtain excellent heat resistance, UV resistance and cold temperature flexibility. Polymerized bitumen then coated onto a dimensionally stable non woven polyester carrier to obtain excellent tensile strength, tear and puncture resistance.

USES

Bituflame is used as waterproofing/damproofing membrane for protection of various substrates in wide range of applications.

INSTRUCTION FOR APPLICATION

Application procedure may vary depending upon site conditions. General application guideline is given below.

Priming

Apply Bitukote Bitumen Primer to a clean, smooth and dry surface by brush, roller or spray. Refer primer data sheet for more details.

Alignment

Unroll and align Bituflame and re roll correctly before torching. Overlap should be 8 to 10mm and end lap should be 100 to 150mm.

Torching

Use gas burner to heat substrate and underside of Bituflame. Embossing on the lower face of the membrane allows a fast and safe laying. When embossing disappears, after torching, the membrane is ready to stick. Roll forward and press firmly against the substrate to bond.

Sealing

Heat both the overlaps and use round tipped trowel to seal the overlap. Excess compound should be smoothened and pressed into seam using hot trowel.

Upstand

All angles and abutments should be sealed with extra care to ensure full bondage. Seal the edges well into the grooves and protect with Bitumastic or Polysulphide sealant.

STORAGE

Bituflame should be stored vertically in clean covered area. Rolls should not be stacked.

HEALTH & SAFETY

All safety measures should be observed during application. Fire extinguishers should be available at site. Care should be taken with gas and torch should not be rested on finished surface or on any materials that can be scorched by flame or hot torch. Protective tools, such as gloves and goggles should be worn by all workers during application.
