Agency for Research on Cancer (IARC) and the National Toxicology Program. This product also contains oxidized asphalt. Occupational
exposures to oxidized asphalt and its emissions during roofing have been classified by IARC as a "probable human carcinogen". Oxidized
asphalt also contains Polycyclic Aromatic Hydrocarbons some of which have been classified by IARC as know or probable human
carcinogens. The physical nature of this product may help limit any inhalation or dermal hazard during application and/or removal. However,
physical forces such as sawing, grinding or drilling during demolition work and heating or burning may increase the inhalation or dermal
exposure hazard of this product. Take precautions to prevent breathing and contact with skin.

Use of this product in "torch applied" or "hot mopped" applications may expose workers and others in the work area to oxidized
asphalt and its emissions. The International Agency for Research on Cancer has classified occupational exposures to oxidized
asphalt and its emissions during roofing as a "probable human carcinogen." During installation and removal of this product,
including "torch applied" or "hot mopped" application, workers must take precautions to assure adequate ventilation and use
effective personal protective equipment to prevent exposures to dusts, fumes, vapors and mists. It is the responsibility of the
contractor and workers to protect themselves and others in the work area from exposure to oxidized asphalt and its emissions
when applying this product.

APPLICATION INSTRUCTIONS

STORAGE

All roong materials must be properly stored in a dry location prior to application. Store materials on platforms off the
ground or roof deck and covered with opaque waterproof tarps that have been properly tied down. During cold or damp
environmental conditions, place the rolls in a heated area. Wet or damp roong materials must never be used in the
construction of a TAMKO roof assembly. To prevent the rolls from becoming deformed, unroll the rolls on the roof and
allow the sun to relax them. Any areas where accidental damage occurs to the roll must be cut out before the material is
installed. All marked factory splices must be cut out and covered with like material.

ROOF DRAINAGE

Proper and adequate drainage of roof surfaces is critical, and a minimum slope of ¼ in. per ft. is recommended. Positive
drainage is required and is the responsibility of those involved in the design and construction of the roof deck and supporting
structure.

COLD WEATHER APPLICATION

Roof application below 40°F can result in problems. Special measures must be taken to insure proper performance of
the roong system. Store materials in a protected environment and limit the amount of time that they are exposed to cold
conditions on the roof.

Since moppings of asphalt tend to chill quickly on a cold deck or insulation, components of the roong system must be
installed rapidly, close to the mop, well embedded, and completely broomed. Asphalt must not be overheated to compensate
for rapid cooling. AWAPLAN should not be applied with asphalt that is below 400°F at the point of application. Do not
mop more than 4 ft. in front of the roll. Immediately press the roll into the hot asphalt by applying pressure to the factory
core in the roll.

The AWAPLAN may need to be unrolled and allowed to relax to atten and warm up prior to application. If this is
necessary, unroll the AWAPLAN and expose the back side of the sheet to the sun. The sun will warm and relax the sheet,
then the AWAPLAN can be rerolled and installed. You may choose to cut the AWAPLAN into lengths of 12 to 18 ft. before
you reroll them. Storage in a heated area immediately prior to application is recommended. Remember the “mop and op”
method of installation is not acceptable with AWAPLAN.

LAYING THE ROOF MEMBRANE

The roof deck must be smooth, dirt free, and moisture free. All exposed (open) edges must have wood nailers. In the case
of steel or masonry roof decks, wood nailers shall be provided around the perimeter of the roof and around all openings
so ashings may be securely fastened. All masonry and metal surfaces that are to receive a mopping of asphalt must rst
be primed with TAMKO’s Asphalt Primer. Begin all plies of roong membrane at the low points. Application will not be
acceptable if at any point the ow of water is against the laps.
