Source Limitations: Obtain EIFS from single source from single EIFS manufacturer and from sources approved by EIFS manufacturer as compatible with EIFS components. 2.2 PERFORMANCE REQUIREMENTS A. EIFS Performance: Comply with ASTM E 2568 and with the following: 1. Weathertightness: Resistant to uncontrolled water penetration from exterior, with a means to drain water entering EIFS to the exterior. 2. Impact Performance: ASTM E 2568, Standard impact resistance, unless otherwise indicated. 3. Bond Integrity: Free from bond failure within EIFS components or between EIFS and substrates, resulting from exposure to fire, wind loads, weather, or other in-service conditions. 2.3 EIFS MATERIALS A. Primer/Sealer: EIFS manufacturer's standard substrate conditioner designed to protect substrates from moisture penetration and to improve the bond between substrate and insulation adhesive. B. Water-Resistive Coatings: EIFS manufacturer's standard formulation and accessories for use as water-resistive barriers; compatible with substrate and complying with physical and performance criteria of ASTM E 2570. C. Insulation Adhesive: EIFS manufacturer's standard formulation designed for indicated use compatible with substrate. D. Molded, Rigid Cellular Polystyrene Board Insulation: Comply with ASTM C 578, Type I. E. Foam Build-Outs: Provide with profiles and dimensions indicated on Drawings.

Reinforcing Mesh: Balanced, alkali-resistant, open-weave, glass-fiber mesh treated for compatibility with other EIFS materials, made from continuous multiend strands with retained mesh tensile strength of not less than 120 lbf/in. according to ASTM E 2098. G. Base-Coat Materials: EIFS manufacturer's standard mixture. H. Waterproof Adhesive/Base-Coat Materials: EIFS manufacturer's standard waterproof formulation. I. Primer: EIFS manufacturer's standard factory-mixed, elastomeric-polymer primer for preparing base-coat surface for application of finish coat. J. Finish-Coat Materials: EIFS manufacturer's standard acrylic-based coating with enhanced mildew resistance. 1. Colors: As indicated. 2. Textures: As indicated. K. Trim Accessories: Type as designated or required to suit conditions indicated and to comply with EIFS manufacturer's written instructions; manufactured from UV-stabilized PVC; and complying with ASTM D 1784, manufacturer's standard cell class for use intended, and ASTM C 1063. PART 3 - EXECUTION 3.1 EIFS INSTALLATION A. Comply with ASTM C 1397, ASTM E 2511, and EIFS manufacturer's written instructions for installation of EIFS as applicable to each type of substrate indicated. B. Trim: Apply trim accessories at perimeter of EIFS, at expansion joints, at windowsills, and elsewhere as indicated. Coordinate with installation of insulation. C. Board Insulation: Adhere insulation to substrate in compliance with ASTM C 1397 and the following: 1. Apply adhesive to insulation by notched-trowel method, with notches oriented vertically to produce drainage channels that remain functional after the insulation is adhered to substrate. 2. Coordinate installation of flashing and insulation to produce wall assembly that does not allow water to penetrate behind flashing and water-resistive barrier. D. Expansion Joints: Install at locations indicated and where required by EIFS manufacturer. E. Waterproof Adhesive/Base Coat: To exposed surfaces of insulation, apply in minimum thickness recommended in writing by EIFS manufacturer over sloped surfaces parapets foam build-outs where indicated on Drawings.

Base Coat: Apply to exposed surfaces of insulation and foam build-outs in minimum thickness recommended in writing by EIFS manufacturer. G. Reinforcing Mesh: Embed reinforcing mesh in wet base coat to produce wrinkle-free installation with mesh continuous at corners, overlapped not less than 2-1/2 inches or otherwise treated at joints to comply with ASTM C 1397 and EIFS manufacturer's written instructions. Do not lap reinforcing mesh within 8 inches of corners. Completely embed mesh, applying additional base-coat material if necessary, so reinforcing-mesh color and pattern are invisible. H. Double-Layer Reinforcing-Mesh Application: Where indicated or required, apply second base coat and second layer of reinforcing mesh, overlapped not less than 2-1/2 inches or otherwise treated at joints to comply with ASTM C 1397 and EIFS manufacturer's written instructions in same manner as first application. Do not apply until first base coat has cured. I. Additional Reinforcing Mesh: Apply strip reinforcing mesh around openings, extending 4 inches beyond perimeter. Apply additional 9-by-12-inch strip reinforcing mesh diagonally at corners of openings (re-entrant corners). Apply 8-inch- wide, strip reinforcing mesh at both inside and outside corners unless base layer of mesh is lapped not less than 4 inches on each side of corners. J. Foam Build-Outs: Fully embed reinforcing mesh in base coat. K. Primer: Apply over dry base coat according to EIFS manufacturer's written instructions. L. Finish Coat: Apply over dry primed base coat, maintaining a wet edge at all times for uniform appearance, in thickness required by EIFS manufacturer to produce a uniform finish of color and texture matching approved sample and free of cold joints, shadow lines, and texture variations. 3.2 FIELD QUALITY CONTROL A. Special Inspections: Engage a qualified special inspector to perform tests and inspections required by authorities having jurisdiction. B. EIFS will be considered defective if it does not pass tests and inspections. END OF SECTION 072419
