THERMOPLASTIC MEMBRANE <br />ROOFING - ADHERED <br />Section 07541 <br />15-1207 <br />Coverage - Typical coverage rates for the 5 gallon box sets are 1,800 to 2,200 sq.ft. <br />All coverage rates are based on 12 inch on center maximum spacing. The minimum <br />ambient and surface temperatures should be 40°F and rising. <br />Approximate Set -Time - Designed to provide approximately 5 - 10 minutes of open time <br />during a typical summer day. The open time will be shorter on hot humid days and <br />longer on cold dry days. <br />Storage - For ease of application, maintain a minimum material temperature of 70°F <br />prior to use. Store in a cool dry location at temperatures between 55°F and 85°F, protect <br />from freezing at all times. Shelf life is 12 months from the date of manufacture. <br />3. Sarnacol OM Board Adhesive: <br />A low odor, VOC compliant, one step foamable polyurethane adhesive used to attach <br />insulation to approved compatible substrates. Adhesive is applied by combining two 5 <br />gallon box sets placed on a cart and dispensed through a combining hose or by hand <br />with a dual component caulk gun. Additional adhesive may be required for rougher <br />surfaces. Consult Product Data Sheets for additional information and for approved <br />substrates and approved insulations. <br />Coverage - Typical coverage rates for the box sets are 10 —20 squares per 10 <br />gallons. Typical coverage rates when using the cartridge is 4 —6 squares per case (4, <br />1500 ml cartridges). All coverage rates are based on 12 inch on center maximum <br />spacing. The minimum ambient and surface temperatures should be 40°F and rising. <br />Approximate Set -Time - Designed to provide approximately 7 - 10 minutes of open time <br />during a typical summer day. The open time will be shorter on hot humid days and <br />longer on cold dry days. <br />Storage - For ease of application, maintain a minimum material temperature of 72°F <br />prior to use. Store in a cool dry location at temperatures between 55°F and 85°F, protect <br />from freezing at all times. Shelf life is 18 months from the date of manufacture. <br />C. Sarnaplate <br />A specially -designed stress plate used with Sarnafasteners to attach an insulation board <br />directly to approved roof decks, Sarnaplate has a high -rib design to increase strength and to <br />provide protection to the membrane underside from abrasion by the fastener head. <br />Sarnaplate is a 3 inch square, 26 gauge stamping of SAE 1010 steel with an AZ 55 <br />Galvalume coating to meet Factory Mutual 4470 criteria for corrosion resistance. Consult <br />Product Data Sheet for additional information. <br />D. Sarnafastener #12 <br />A #12 corrosion -resistant fastener used with Sarnaplates to attach insulation boards to steel <br />or wood roof decks. Sarnafastener #12 has a modified buttress thread, a shank diameter of <br />approximately 0.168 inch and a thread diameter of approximately 0.214 inch. The driving <br />head has a diameter of approximately 0.435 inch with a #3 Phillips recess for positive <br />engagement. Consult Product Data Sheet for additional information. <br />12 <br />
