D. Do not use c�en flames for drying of surfaces, sealants, or adhesives. <br /> E. Do not use oil-based paint on PVC Coated Metal or membrane. Contact Mule-Hide's <br /> Customer Service Departrnent for recommendations. <br /> F. Do not allow muriatic aad (masonry cleaner) to come in direct contact with the Mule-Hide <br /> PVC Membrane or accessory products. <br /> PART 3 - EXECUTION ' <br /> 3,01 General <br /> When instaliing a MechanicallyAttached Mule-Hide Reinforced PVC Membrane Roofing System in cooler <br /> weather, it is recommended that liquids such as solvents, sealants, etc. be stored at temperatures <br /> betw�een 60°F and 80°F until just prior to use in order to f�ilitate the installation. Liquid products, if <br /> stored outdoors, should be brought up to room temperature prior to use. <br /> 3.02 Substrate Conditions <br /> The following general c�nditions apply to the substrate that will receive a Mechanically Attached Mufe- <br /> Hide PVC Membrane Roofing System for both reroof and new construction: <br /> A. The roof deck must be structuratly sound to provide proper securement for mechanicat <br /> fasteners. Areas showing a loss of integrity due to corrosion, rotting, warping, concrete <br /> spalling, etc., must be repaired or replaced prior to installing the r�ng system. <br /> B. It is imperative that the rooFing contractor performs test cuts at each roaf area prior to <br /> reroofing. The condition aF the substrate must be suitable to receive a Mechanically <br /> Attached Mule-Hide PVC Roafing System. Wet insulation must be remaved and <br /> replaced. See SPRI's guidelines for deterrriir�ng wet insulation. <br /> C. A determination must be made regarding the presence or absence of coal tar pitch within <br /> the existing roof assembly. The presence af coal tar pitch requires a separation layer of <br /> insulation a minimum aF 1-1/2" thick having a minimum "R" value of 5.0 if the coal tar <br /> pitch is 10 years or older. All joints must be butted tightly together or have joints <br /> completely taped to prevent vola6les from damaging roof inembrane. lf the existing <br /> assembly is less than 10 years old, specific procedures must be fallowed. Contact Mule- <br /> Hide Customer Service Department for specific requirements. <br /> D. Contact Mule-Hide Customer Service Department when the substrate is exposed to <br /> excessively high humidity and/or a corrosive environment. Speaal fasteners (i.e., <br /> staintess steel) or details may be required. <br /> E. ft is acceptable to install a Mechanically Attached Mule-Hide PVC Membrane Roofing <br /> System over the following dedc substrates provided that an acceptable insulation, <br /> barrier/cover board or an appropriate slip sheet is installsd over the substrate as needed: <br /> 1. Structural Metal Deck (24gauge minimum) shall conform to recommendations <br /> outlined in Factory Mutual's Loss Prevention Data Sheet 1-28. Pullout tests are <br /> required on all decks less than 22 gauge. An inrulation or barrier bosrd is <br /> required to provide a smooth surface and shall be of suffiaent thidcness to span <br /> the steel flutes without damage from traffic. <br /> 2• Plywood should conform to Fadory Mutual's requirements should tested (for <br /> uplift) assemblies be required. For non-FM as.semblies, plywood minimum <br /> thickness shall be determined by local code requiremer�ts but shall not be less <br /> 8 <br /> , <br />
