AWAPLAN

APPLICATION INSTRUCTIONS
BASE PLY

Install one or more base plies prior to the application of AWAPLAN. TAMKO Glass-Base

, Type 43 Organic Base

Sheet, Tam-Ply IV

, and Versa-Base

are the recommended base ply materials. Alternatively, base sheets that meet the

requirements of ASTM D4601, Type II; ASTM D2178, Type IV or Type VI; ASTM D2626; ASTM D6163, ASTM D6164

or ASTM D4897, Type II are acceptable. The base sheet shall have minimum side laps of 2 in. and end laps of 4 in.

Not all application methods apply to all base sheets. Certain base plies are limited in the manner in which they may be

applied. Consult the base ply manufacturer’s application instructions for the base ply used and the current National Roofing

Contractor Association (NRCA) Manual - Membrane Roof Systems for installation instructions. See the chart below for

information regarding acceptable application methods of TAMKO base sheets.

HOT ASPHALT APPLICATION

Interply moppings of asphalt shall consist of approximately 23 lbs. (±15%) per 100 sq. ft. of roof area. For any surfaces

including insulating materials which absorb asphalt, it may be necessary to apply the asphalt in greater quantities to assure

adequate adhesion. Avoid excessive interply moppings as slippage may result. The asphalt must meet ASTM D312,

Type III for slopes up to ¼ in. and Type IV for slopes up to 3 in. The asphalt must be a minimum of 400°F at the point of

application. MOP NO FURTHER 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 membrane shall have side laps of 4 in. and end laps

of 6 in. The entire sheet, including the side and end laps, must be totally adhered in asphalt with no void areas. A small

amount of asphalt protruding from the side and end laps is acceptable. However, care should be taken to avoid excessive

amounts of asphalt at the lap. All exposed asphalt in excess of ¼ in. width should be covered with granules.

COLD ADHESIVE APPLICATION

TAM-PRO® M3 Adhesive or TAM-PRO 856 Premium SBS Adhesive may be applied using a 3/16” V notched squeegee

or TAM-PRO M3 Adhesive may be applied using spray equipment designed for this purpose. The rate of application is

approximately 1-1/2 gallons per square for squeegee application and 1-1/2 to 2-1/2 gallons per square for spray application.

CAUTION: Using excessive amounts of cold adhesive may cause blistering or damage to the finished AWAPLAN

membrane.

For TAM-PRO 856 Premium SBS Adhesive, the side and end laps must be set in adhesive or heat welded.

For TAM-PRO M3 Adhesive, it is recommended that the side and end laps be heat welded.

Use same technique as outlined in HOT ASPHALT APPLICATION for side and end laps. Use adhesive only in well-

ventilated areas.

Alternatively, a cold process adhesive that meets the requirements of ASTM D3019, Type III may be used. Follow the

manufacturer’s application requirements.
