PART 3 - EXECUTION <br /> 3 . 1 EXAMINATION <br /> A. Examine areas and substrates, with Installer present, and including welded hollow-metal frames, cast-in <br /> anchors, and structural framing, for compliance with requirements and other conditions affecting <br /> performance. <br /> 1 . Proceed with installation only after unsatisfactory conditions have been corrected. <br /> 3 .2 PREPARATION <br /> A. Protect adjacent work from soiling, spattering, moisture deterioration, and other harmful effects caused <br /> by plastering. <br /> B . Prepare solid-plaster bases that are smooth or that do not have the suction capability required to bond <br /> with plaster according to ASTM C 926 . <br /> 3 . 3 INSTALLING ACCESSORIES <br /> A. Install according to ASTM C 1063 and at locations indicated on Drawings. <br /> B . Control Joints : Install control joints at locations indicated on Drawings . <br /> 1 . As required to delineate plasterwork into areas (panels) of the following maximum sizes : <br /> a. Vertical Surfaces : 144 sq. ft. ( 13 .4 sq. m) . <br /> b . Horizontal and other Nonvertical Surfaces : 100 sq. ft. (9. 3 sq. m) . <br /> 2 . At distances between control joints of not greater than 18 feet (5 . 5 m) o . c . <br /> 3 . As required to delineate plasterwork into areas (panels) with length-to-width ratios of not greater <br /> than 2- 1 /2 : 1 . <br /> 4 . Where control joints occur in surface of construction directly behind plaster. <br /> 5 . Where plasterwork areas change dimensions, to delineate rectangular-shaped areas (panels) and to <br /> relieve the stress that occurs at the comer formed by the dimension change. <br /> 3 .4 PLASTER APPLICATION <br /> A. General: Comply with ASTM C 926 . <br /> 1 . Do not deviate more than plus or minus 1 /4 inch in 10 feet (6 .4 mm in 3 m) from a true plane in <br /> finished plaster surfaces, as measured by a 10-foot (3 -m) straightedge placed on surface . <br /> 2 . Grout hollow-metal frames, bases, and similar work occurring in plastered areas, with base-coat <br /> plaster material, before lathing where necessary. Except where full grouting is indicated or <br /> required for fire-resistance rating, grout at least 6 inches ( 152 mm) at each jamb anchor. <br /> 3 . Finish plaster flush with metal frames and other built-in metal items or accessories that act as a <br /> plaster ground, unless otherwise indicated. Where casing bead does not terminate plaster at metal <br /> frame, cut base coat free from metal frame before plaster sets and groove finish coat at junctures <br /> with metal. <br /> 4 . Provide plaster surfaces that are ready to receive field-applied finishes indicated. <br /> Wabasso Beach Park <br /> Indian River County <br /> DAA Project No. 6008 <br /> 09220 - 4 <br />
