J. <br /> <br />K. <br /> <br />L. <br /> <br /> M. <br /> <br />N. <br /> <br />O. <br /> <br />3. Job-combined formulation of manufacturer's standard polymer-emulsion adhesive and manufac- <br /> turer's standard dry mix containing portland cement. <br />4. Job-mixed formulation of portland cement complying with ASTM C 150, Type I, white or natural <br /> color; and manufacturer's standard polymer-emulsion adhesive designed for use indicated. <br />5. Any formulation indicated above. <br /> <br />Primer: System manufacturer's standard factory-mixed elastomeric-polymer primer for preparing base- <br />coat surface for application of finish coat. <br /> <br />Base Coat for Horizontal Surfaces: Dryvit Dry-Flex waterproof base coat or equivalent. <br /> <br />Finish-Coat Materials: System manufacturer's standard factory-mixed formulation of polymer-emulsion <br />binder, colorfast mineral pigments, sound stone particles, and fillers. <br /> <br />Finish Coat for Horizontal Surfaces: Dryvit "Weatherlast" exterior elastomeric architectural coating <br />and waterproofing or equivalent. <br /> <br />Water: Potable. <br /> <br />Trim Accessories: Complying with ASTM C 1063; vinyl plastic. <br /> <br />Elastomeric Sealants: Listed and recommended by system manufacturer; compatible with joint fillers, <br />joint substrates, and other related materials; and comply with requirements in "EIMA Guide for Use of <br />Sealants with Exterior Insulation and Finish Systems, Class PB" and in Division 7 Section "Joint Seal- <br />ants" for products indicated below. Sealant color per Engineer's selections fi.om manufacturer's full <br />range of standard colors. <br />1. Low-modulus silicone sealant. <br /> <br />1.3 <br /> <br /> A. <br /> <br />EXECUTION <br /> <br />Primer-Sealer: Apply over gypsum sheathing and over other substrates where required by system <br />manufacturer for improving adhesion or for protecting substrates fi.om degradation. <br /> <br />Comply with ASTM PS 49 and system manufacturers written instructions for installation of system. <br /> <br />Apply trim accessories at perimeter of system, at expansion joints, and elsewhere, as indicated. Use <br />drip screed at bottom edge of system and casing beads at other locations. <br /> <br />Adhesively attach insulation by notched-trowel method to comply with ASTM PS 49 and system manu- <br />facturer's written requirements. Locate joints so no piece of insulation is less than 12 inches wide or 6 <br />inches high. Offset joints not less than 6 inches from comers of window and door openings. Offset <br />joints of insulation not less than 6 inches from horizontal and 4 inches from vertical joints in sheathing. <br />Interrupt insulation for expansion joints. Form joints for sealant application wide enough to produce <br />joint widths indicated after encapsulating joint substrates with base coat and reinforcing mesh. <br /> <br />Offset joints of insulation not less than 4 inches from aesthetic reveals. <br />Install foam shapes attached to supporting substrate. <br />Wrap exposed edges of insulation board with reinforcing mesh fully encapsulated in base coat <br />and, except where edge is substrate for joint sealant, finish coat. <br />Treat edges of insulation board at trim accessories by extending base coat, reinforcing mesh, and <br />finish coat over face leg of accessories. <br />Coordinate flashing installation with installation of insulation. <br /> <br />EXTERIOR INSULATION AND FiNISH SYSTEMS - CLASS PB M:/Snapier/Spec 07241 - 3 <br /> <br /> <br />
