KO <br /> Installation Instructions for <br /> Asphalt Shingles <br /> Page 2 of 5 <br /> IKO Shingle Application Instructions — 3-Talc Shingles <br /> (ASTM 133161, Class F— IKO Marathon 25 AR and CRC Superglass M25AR) <br /> NOTE: THESE INSTRUCTIONS SHALL BE USED IN CONJUCTION WITH IKO'S PUBLISHED <br /> APPLICATION INSTRUCTIONS AND THE APPLICABLE CODE. IN THE EVENT THE INSTRUCTION <br /> CONFLICT, THESE INSTRUCTIONS WILL GOVERN. <br /> ROOF DECK: Solidly sheathed and fastened deck conforming to 2017 FBC. <br /> UNDERLAYMENT:Applied in accordance with building code requirements. For areas where the roof slope is <br /> less than 4" per foot down to 2" per foot, use 2 layers of underlayment conforming to building code <br /> requirements, the first sheet overlapping the eave protection by 19",followed by full 36"widths overlapping <br /> each preceding course by 19"or other Approved underlayments in accordance with the qualified application <br /> instructions. For areas where the roof slope is 4" per foot or greater, cover the deck with one ply of <br /> underlayment laid parallel to the eaves,with 2"horizontal laps and 4"end laps. Apply metal drip edges on top <br /> of any underlay along rake edges and directly to the deck along eaves in accordance with building code <br /> requirements. <br /> NAILING: Use galvanized(zinc coated)roofing nails, 11 or 12 gauge,with at least 3/8"diameter heads,long <br /> enough to penetrate through plywood or 3/4"into boards. Use 4 nails per shingle placed 6-1/8"above the butt <br /> edge, approx. 1"and 13"from each end and 1/2"above each cutout. Drive nails straight so that nail head is <br /> flush with, but not cutting into shingle surface. <br /> NAILING ON STEEP SLOPES: For steep slopes of 21"per foot(600)or more, use 6 nails per shingle placed <br /> as shown below. Ensure that no nail is within 2"of a joint/cutout of the underlying shingle. Seal down each <br /> shingle at time of application with three 1"diameter(approx.size and thickness of a quarter)spots of asphalt <br /> plastic cement placed under the shingle 2" above the bottom edge and equally spaced along the shingle. <br /> Apply plastic cement in moderation since excessive amounts may cause blistering. CAUTION: Shingles <br /> should seal to the underlying course when the factory applied asphalt sealant is sufficiently warmed by the <br /> heat of direct sunlight. <br /> EXPOSURE: Installed shingles shall have a maximum average exposure of 5-5/8". <br /> STEEP SLOPES <br /> 1-0t2" 1-1lL" <br /> } <br /> rb SEALJNU STRIP <br /> NAILS NAILS <br /> DO NOT WAIL INTO OR ABOVE THE SEALING STRIP <br /> PRI Construction Materials Technologies,LLC. 6412 Badger Drive Tampa,FL 33610 Tel:813-621-5777 Fax:813-621-5840 e-mail:materialstesting@pricmtcom WebSite:hftpJ/www.pricmt.com <br />
