D. Do not use open flames for drying of surfaces, sealants, or adhesives. E. Do not use oil -based paint on PVC Coated Metal or membrane. Contact Mule- Hide's Customer Service Department for recommendations. F. Do not allow muriatic add (masonry cleaner) to come in direct contact with the Mule -Hide PVC Membrane or accessory products. PART 3 - EXECUTION 3.01 General When installing a Mechanically Attached Mule -Hide Reinforced PVC Membrane Roofing System in cooler weather, it is recommended that liquids such as solvents, sealants, etc. be stored at temperatures between 60 °F and 80 °F until just prior to use in order to facilitate the installation. Liquid products, if stored outdoors, should be brought up to room temperature prior to use. 3.02 Substrate Conditions The following general conditions apply to the substrate that will receive a Mechanically Attached Mule - Hide PVC Membrane Roofing System for both reroof and new construction: A. The roof deck must be structurally sound to provide proper securement for mechanical fasteners. Areas showing a loss of integrity due to corrosion, rotting, warping, concrete spelling, etc., must be repaired or replaced prior to installing the roofing system. B. It is imperative that the roofing contractor performs test cuts at each roof area prior to reroofing. The condition of the substrate must be suitable to receive a Mechanically Attached Mule -Hide PVC Roofing System. Wet insulation must be removed and replaced. See SPRI's guidelines for determining wet insulation. C. A determination must be made regarding the presence or absence of coal tar pitch within the existing roof assembly. The presence of coal tar pitch requires a separation layer of insulation a minimum of 1 -1/2" thick having a minimum "R" value of 5.0 if the coal tar pitch is 10 years or older. All joints must be butted tightly together or have joints completely taped to prevent volatiles from damaging roof membrane. If the existing assembly is less than 10 years old, specific procedures must be followed. Contact Mule - Hide Customer Service Department for specific requirements. D. Contact Mule -Hide Customer Service Department when the substrate is exposed to excessively high humidity and /or a corrosive environment. Special fasteners (i.e., stainless steel) or details may be required. E. It is acceptable to install a Mechanically Attached Mule -Hide PVC Membrane Roofing System over the following deck substrates_pfgvjgjgsi that a0 at -,ref tayP iRC„iat��,.l barrier /cover board or an appropriate slip sheet is installed over the substrate as needed: 1. Structural Metal Deck (24 -gauge minimum) shall conform to recommendations outlined in Factory Mutual's Loss Prevention Data Sheet 1 -28. Pullout tests are required on all decks less than 22 gauge. An insulation or barrier board is required to provide a smooth surface and shall be of sufficient thickness to span the steel flutes without damage from traffic. 2. Plywood should conform to Factory Mutual's requirements should tested (for uplift) assemblies be required. For non-FM assemblies, plywood minimum thickness shall be determined by local code requirements but shall not be less 8
