          PART 3EXECUTION
 
          3.1EXAMINATION
 
          A.Do not begin installation until substrates have been properly prepared.
 
          B.If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
          ** NOTE TO SPECIFIER ** Delete if not required.
 
          3.2EPDM AND TPO - SINGLE PLY ROOFING ADHESIVE INSTALLATION
 
          A.Preparation:
          1.Roof deck that shows signs of deterioration or loss of structural integrity shall be repaired or replaced prior to roof system installation.
          2.Clean surfaces thoroughly prior to installation.
          3.Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
          4.Do not install in direct contact with asphalt or coal tar pitch. Cover boards shall be installed over these surfaces prior to membrane installation.
          5.Surfaces to be bonded shall be clean, dry and free from dirt, dust, oil, loose paint, wax or grease, etc. All fasteners shall be properly seated and flush to the surface.
 
          B.Installation:
          1.Install in accordance with manufacturer's instructions.
          2.Ideal temperatures of the adhesive and the surfaces being bonded shall be between 60 degrees and 80 degrees F (16 degrees to 27 degrees C). Temperatures outside this range may affect bonding range and ability to be spray-applied. Colder temperatures will require longer dry times and hotter temperatures will shorten the bonding range.
          3.The adhesive shall be applied to both surfaces with a coating weight of at least 1.0 oz (2.5 grams) of dry adhesive per square foot per surface.
          4.Allow to dry until adhesive is tacky but does not transfer when touched, approximately 1-5 minutes, depending on temperature and humidity. Precaution shall be taken to not allow the adhesive to over dry. If bonding range of approximately 20 minutes is exceeded, recoat at least one of the surfaces.
          5.Position surfaces carefully before assembly, no adjustment is possible after contact. Join surfaces with firm and uniform pressure. Adequate pressure can be achieved by roller or push broom. A carpet pad can be used with a heavy roller (75-100 lbs.) to protect the membrane from damage.
          ** NOTE TO SPECIFIER ** Delete if not required.
 
          3.3POLYURETHANE FOAM INSULATION ADHESIVE INSTALLATION
 
          A.Preparation:
          1.Roof deck that shows signs of deterioration or loss of structural integrity shall be repaired or replaced prior to roof system installation.
          2.Clean surfaces thoroughly prior to installation.
          3.Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
          ** NOTE TO SPECIFIER ** Delete substrate not required.
          a.Lightweight concrete, structural concrete, and plywood: Surfaces shall be free of debris, dirt, oil, grease, and water before application.
          b.Built-ups (BUR) and Modified Roof Membranes (MBR): Surfaces shall be free of any debris, dirt, oil, grease, and water.
          c.Steel: The upper flange of the steel deck (bonding surface) surfaces shall be free of any debris, dirt, oil, grease, and water. The shop oil coating of new steel shall be removed. The bonding surface shall be free of any cleaner before applying adhesive.
          4.Adhesive shall be used with insulating board stock maximum size of 4 feet by 4 feet (1219 mm by 1219 mm) and applied as required by the NRCA Membrane Roof Systems Manual: Section 2-10 Polyisocyanurate Insulation.
          5.Adhesive shall be applied when ambient or substrate temperatures are above 40 degrees F (4 degrees C) and rising.
          6.Do not apply adhesive during inclement weather.
          7.Do not apply adhesive to wet surfaces.
 
          B.Installation:
          1.Install in accordance with manufacturer's instructions.
          2.The product temperature prior to application shall be between 70 degrees F and 90 degrees F (21 degrees C and 32 degrees C).
          3.The adhesive shall be applied in rows placed a maximum of 12 inches (305 mm) OC.
          4.Insulation boards shall be placed immediately on the wet adhesive but not walked into place or compressed into the adhesive until the adhesive has begun to thicken and started to develop its initial bond.
          5.Boards that will not lay flat due to cupping, warping or crowning, or surface irregularities of the substrate, shall have weights placed on the boards until the adhesive has achieved adequate adhesion to hold the boards in place.
          6.After the adhesive has attained its initial bond strength the boards can be "walked-in" and will be compressed to the deck or substrate exhibiting minimal slippage or movement. The boards shall be exposed to minimum traffic for at least 10 to 20 minutes (depending on temperature) after they have been "walked-in-place" to avoid breaking the freshly formed bond.
          7.Membranes shall be applied once the adhesive has achieved sufficient bond strength to the substrate to which it is adhered.
          8.Contractor shall inspect the installed insulation for proper adhesion and adhere boards and/or corners that are not adequately attached.
          ** NOTE TO SPECIFIER ** Delete if not required.
 
          3.4ADHESIVE INSTALLATION
 
          A.Application: Apply to clean, dry surfaces. Do not apply to wet materials. Install in accordance with manufacturer's recommendations.
          ** NOTE TO SPECIFIER ** Delete if not required.
 
          3.5FLASHING TAPE INSTALLATION
 
          A.Preparation:
          1.Substrate Temperature Range: 0 degrees F (-18 degrees C) up to 120 degrees F (49 degrees C).
          2.Surfaces shall be free from dirt and debris and have not absorbed water. Surfaces shall be free of any damaged, unsupported areas, sharp protrusions or voids.
          3.For difficult to stick to surfaces, test flashing tape adhesion before application. Prime the substrate prior to applying the flashing tape.
 
          B.Application: Install in accordance with manufacturer's recommendations.
          1.To apply, peel back a few inches of one side of the split paper release liner to position the tape. Remove the liner while applying firm pressure to the flashing tape surface as it comes into contact with the building surface. Repeat this procedure with the remaining side of the paper release liner and tape. Using a roller (rubber, wood or steel "J" roller) apply sufficient pressure along the entire tape surface to ensure a continuous seal and to eliminate trapping air beneath the tape.
          2.Environmental Exposure: Exposure to direct sunlight no greater than 6 months.
          3.The paper release liner is slippery and shall not be walked on at any time. Dispose of the paper release liner during installation to avoid slipping hazard.
          ** NOTE TO SPECIFIER ** Delete if not required.
 
          3.6SEAMING TAPE INSTALLATION
 
          A.Application: Apply to clean, dry surfaces. Do not apply to wet materials. Install in accordance with manufacturer's recommendations. Insure proper rubdown of the tape to the substrate for optimum performance.
 
          3.7PROTECTION
 
          A.Protect installed products until completion of project.
 
          B.Touch-up, repair or replace damaged products before Substantial Completion.
