Mock-ups Section B. Miscellaneous Metals Section C. Architectural Woodwork Section D. Gypsum Board Assemblies - Section E. Painting and Finishing - Section QUALITY ASSURANCE A. Qualifications of Installers: For actual cutting and installation of wall surfacing, use only thoroughly trained and experienced installers completely familiar with the installation recommendations of the manufacturer of the wall surfacing used and completely familiar with the requirements of this work. B. Manufacturer's Recommendations: The installation recommendations of the manufacturer of the wall surfacing material used, when approved by the Architect, shall be the basis for acceptance or rejection of actual installation methods used in this work. C. Test Panels: Install 2 test panels of full usable width in areas designated by the Architect. Replace test panels which are not acceptable to the Architect until satisfactory installation is achieved. 1.5 SUBMITTALS A. Samples: Before any wall surfacing is delivered to the job site, submit to the Architect samples of the full range of colors and patterns of wall surfacing available from the selected manufacturer in the quality and type specified. Samples shall be a min. 18" x 18" in size / 1 of 5

2 B. Manufacturer s Recommendations: Accompanying the samples, submit to the Architect copies of the manufacturer's current installation recommendations for the material proposed to be furnished and installed under this Section. C. A Certificate of Compliance shall be furnished indicating conformance to the specification requirements. This requirement may be waived if wall surfacing material and adhesive packages and containers delivered to the job carry labels indicating weight of materials and fire hazard classification. 1.6 MAINTENANCE INSTRUCTION A. Furnish the Owner with a copy of the manufacturer's maintenance instructions. These instructions shall contain recommended cleaning materials, application methods, and precautions to be followed in the use of cleaning materials which may be detrimental to the surface if improperly applied. 1.7 PRODUCT DELIVERY, STORAGE AND HANDLING A. Deliver and store all wall surfacing material in undamaged condition as packaged by the manufacturer, with manufacturer's seal and labels intact. Exercise care to prevent damage during delivery, handling and storage. Store all materials flat in a clean, dry area with maintained temperature above 40 deg. F. 1.8 ENVIRONMENTAL CONDITIONS A. Wall surfacing should be installed only when normal temperature and humidity conditions approximate the same conditions that will exist when the building is occupied. B. Areas to receive wall surfacing shall be a constant temperature of 70 deg. F. measured at base elevation and shall be maintained for 72 hrs. before, during and 48 hrs. after the application. C. Remove wall surfacing material from its packaging and allow to acclimatize to the area of installation 24 hrs. PART 2 PRODUCTS 2.1 MATERIALS (BASIS OF DESIGN) A. Provide "Linoleum Bulletin Board UM" by Forbo, or approved equal by one of the following: Wall Talkers, or Koroseal 1. TKBS: Manufacturer: Forbo, Collection: Bulletin Board, Product Number: 2162,, Backing: Jute, / 2 of 5

3 B. Tackable Wall Surfacing (TKBS) 1. Provide resilient homogeneous, tackable surface material consisting of linseed oils, granulated cork, resin binders, mixed and calandered onto a natural burlap backing equal to Forbo Industries or approved equal. Unicolor shall extend throughout thickness of material; product shall contain no harmful by-products or carcinogens. Product shall conform to the following characteristics: a. Width: 48". b. Gauge: 1/4". c. Length: 90 lineal feet approx. d. Backing: Burlap. e. Material Flexibility: Will not crack or break around a 2-3/4 diameter cylinder. f. Fuel Contribution (ASTM E 84): Class II. 2. Adhesive: Provide "Forbo 511 Plus" adhesive as recommended by manufacturer. PART 3 EXECUTION 3.1 INSPECTION A. Examine the areas and conditions where the wall surfacing is to be installed and correct any conditions detrimental to the proper and timely completion of the work. Do not proceed with the work until unsatisfactory conditions are corrected to permit proper installation of the work. 3.2 PREPARATION A. Cut sheets of wall surfacing materials with required length, including 2" to 3" overlap, preferably 24 hours prior to installation. Lay sheets flat and allow to acclimatize at a minimum temperature of 68 deg. F. Back roll sheets once in reverse direction to release roll stretch. B. Cutting to Size 1. Cut a sheet from the roll of Bulletin Board, allowing some length of overlap. 2. Remove factory edge from both sides with a Forbo Seam and Strip Cutter. A straight edge, utility knife and hooked blade knife may also be used to trim the factory edge. 3. Trim off a minimum of 1/2". With utility knife, score material about 1/3 the material thickness. Then with the hooked blade knife, cut along the score line, holding the knife at an angle, to slightly undercut the edge. 4. Cut straight along the top edge or direct scribe. The bottom edge shall be cut to size by direct scribing during installation / 3 of 5

Press the sheet of Bulletin Board into the fresh adhesive, starting with the top edge and the side along the perpendicular pencil line. 2. Work from the top downwards, first widthwise, then lengthwise. 3. Roll firmly through the width then the length with a hand roller to insure proper transfer of adhesive and to remove all air bubbles. 4. Remove adhesive residue immediately with a damp cloth. Mineral spirits may be used to remove dried adhesive. 5. The first sheet shall now be fully cut in, adhered and rolled. D. Seaming with Subsequent Sheets 1. Cut the subsequent sheet to required length, including 2" to 3" overlap. Note: Do Not Reverse Sheet. Install all Linoleum Sheets in same direction. 2. Overlap at seam shall be a minimum of 1/2". 3. Using the Forbo Seam and Strip Cutter, trim the factory edge on opposite side to prepare for the next seam. 4. Draw a pencil line on the wall where next seam line will fall. 5. Spread the Forbo 511 Plus Adhesive with proper notched trowel. 6. Spread from the edge of the first sheet up to the pencil line at the seam edge of the second sheet. 7. If necessary, apply 10" to 12" of contact adhesive or acrylic dispersion to the upper part of the wall and to the back of the Bulletin Board, to prevent the sheet from sliding down along the fresh adhesive. 8. Immediately after material has been laid into wet adhesive, underscribe the seam. E. Remove switchplates, wall plates, and surface-mounted fixtures, where wall surfacing is to be applied. F. Prime and seal substrates in accordance with the wall surfacing manufacturer's recommendations for the type of substrate materials to be covered. G. Surfaces to receive wall surfacing shall be free from grit, loose particles and surface irregularities and shall meet the min. requirements established by the wall surfacing manufacturer. Fill all cracks and holes in gypsum board with patching compound and sandpaper smooth / 4 of 5
