TAMKO AWAPLAN - Manual (Page 2)

AWAPLAN TM
APPLICATION INSTRUCTIONS
STORAGE
All roofing 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 roofing 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 roofing 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 roofing 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 flatten 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 flop”
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 flashings may be securely fastened. All masonry and metal surfaces that are to receive a mopping of asphalt must first
be primed with TAMKO’s Asphalt Primer. Begin all plies of roofing membrane at the low points. Application will not be
acceptable if at any point the flow of water is against the laps.
