ROOFING REPLACEMENT, RECOVER AND REPAIR PROJECT PAGE 7 <br />INDIAN RIVER COUNTY - JAIL COMPLEX SECTION 075620 <br />JANUARY 4, 2018 GUTTER WATERPROOFING <br />A. Surface Preparation: <br />1. Metal <br />a) All exposed metal surfaces to be coated must be cleaned by power tool <br />cleaning (SSPC .SP -3) to remove all corrosion deposits back to a clean, bright <br />metal, followed by a solvent wipe prior to application of specified primer: <br />b) Fill any gaps or voids at the juncture of the gutter penetrations with a single <br />component polyurethane sealant, and allow to cure per manufacturer's instructions <br />prior to overcoating with the waterproofing system. <br />B. Priming <br />Metal <br />a) Apply Sikalastic Metal Primer (Epoxy Primer) to previously prepared metal <br />and drain bowls by brush, roller or airless spray at a rate of 200-250 SF/gallon, to <br />achieve an overall wet film thickness of 6-8 mils. High porosity and roughness of the <br />substrate will decrease coverage rates. <br />b) Allow to cure and dry in accordance with manufacturer's instructions. <br />C. Local Reinforcement (Cracks, Gutter Joints, and Dissimilar Material Transitions) <br />1. Apply a minimum 1" bond break at repaired cracks, gutter joints, and transitions <br />between .dissimilar materials, prior to applying the specified membrane system. Bond <br />break should be installed centered over each joint or crack. <br />2. Follow by applying a local stripe coat of polyurethane resin at a width a minimum <br />of 1" wider than the reinforcement, and while wet, insert nylon tape reinforcement into <br />the wet membrane and backroll to fully embedment adding additional material as <br />needed. <br />3. Ensure that local reinforcing mesh is not in tension during embedment. <br />D. Membrane Application <br />The following Sikalastic RoofPro (Decothane) system is specified for this project. <br />Please note, these tables specify the warranted roofing system components and <br />do not include additional optional anti-skid or decorative finishes which may be <br />specified. <br />
