THE CITY OF SUNNY ISLES BEACH <br />PROJECT NO. 21-1011 <br />BUILDING DEPARTMENT RELOCATION TO ANNEX <br /> <br />Project No. 21-1011 November 2024 092900-5 <br /> <br />a. On partitions higher than 8’-1” apply gypsum board vertically (parallel to <br />framing), unless otherwise indicated. <br />b. On partitions 8’-1” or less in height apply gypsum board horizontally <br />(perpendicular to framing) <br /> <br />C. Partition Systems: Install according to details on Drawings. Stagger junction boxes and <br />outlets on opposite sides of a partition, separated by a metal stud. Do not cover boxes <br />installed back-to-back until relocated. <br /> <br />D. Ceilings: Apply wallboard directly to furring channels, wire suspended cold rolled channels, <br />or screw studs. <br /> <br />1. Apply gypsum board with long dimension at right angles to the furring channels or <br />screw studs. Center end joints over furring channels, neatly fitted and staggered. <br />Use boards of maximum practical lengths to minimize end joints. <br /> <br />2. Do not frame ceiling directly to wall studs at fire and sound rated partitions, to <br />allow uninterrupted sound and fire barrier. <br /> <br />E. Joint Treatment: Treat joints, screw head depressions and defects incurred during the <br />installation of the gypsum board in accordance with manufacturer's joint treatment <br />directions, using recommended tape, joint compound and recommended methods of the <br />manufacturer. <br /> <br /> 1. Taping and Embedding: <br /> <br />a. Apply taping or embedding compound in a thin, uniform layer to joints and <br />angles. <br />b. Immediately apply reinforcing tape centered over joint or angle and firmly <br />seat into compound. Sufficient compound (approximately 1/64" to 1/32") <br />shall remain under tape to provide proper bond. <br />c. Immediately follow with a thin skim coat to embed tape but not function <br />as a second coat. <br />d. Fold and embed tape properly at interior angles to provide a true angle. <br />e. Tape or embedding coat shall be thoroughly dry before application of <br />second coat. <br /> <br /> 2. Second Coat Embedding: <br /> <br />a. Apply a second coat of joint compound over embedding coat, filling panel <br />taper flush with surface. <br />b. Cover tape and feather out at least 2 inches on each side beyond first coat. <br />c. On joints with no taper, cover tape and feather out at least 4 inches on <br />either side of tape. <br />d. Allow second coat to dry thoroughly before application of finish coat. <br /> <br /> 3. Topping: <br />
