☐ Attic-stock delivery record (product, color, dye lot, quantity)
4 Quality Assurance
NOTE Installer qualifications determine adhesion quality, seam appearance, and color consistency; these requirements apply to the firm responsible for the wall covering work. (4.1)
4.1.1The installer shall be a firm with a minimum of three years of documented experience installing flexible wall coverings of the type and scale specified.
4.1.2The installer shall be acceptable to the wall covering manufacturer for installation of the submitted products.
4.1.3A single installer shall be responsible for the wall covering work in each contiguous area to maintain uniform appearance and accountability for seams and color match.
NOTE Wall covering, adhesive, and the substrate finish form an interdependent assembly; substituting any one element after the fire test or adhesive approval can void the listed performance, so substitutions are controlled. (4.2)
4.2.1Material from a single manufacturer shall be furnished for each wall covering type to establish single-source responsibility for performance and color consistency.
4.2.2All material for each continuous color and pattern shall be furnished from a single dye lot, and rolls shall be hung in sequence by run number.
4.3The Contractor shall install a mockup for each wall covering type and each special condition (inside corner, outside corner, and termination at base and ceiling) for the Architect's review of appearance, seam treatment, and substrate telegraphing.
4.3.1The approved mockup shall establish the standard of workmanship for the work and may remain as part of the finished work if undamaged and undisturbed.
5 Use Type and Durability
NOTE ASTM F793/F793M classifies wall coverings into use categories (Type I through Type VI) by total weight, abrasion resistance, breaking strength, tear resistance, and related characteristics; Type I (light-duty), Type II (medium- and heavy-duty), and Type III (heavy-duty) are the categories specified for commercial construction. (5.1)
NOTE Light-duty Type I covering fails quickly at chair-rail height in trafficked corridors; specify Type II as the default for any commercial public space, and reserve Type I for low-traffic private rooms and ceilings. (5.2)
NOTE Type III heavy-duty covering is specified in high-impact zones such as hospital patient corridors, service corridors, and food-service circulation where impact, scrubbing, and cleaning chemicals are routine. (5.3)
5.3.1The wall covering use type shall be selected to suit the traffic level and occupancy of each area.
5.3.2The wall covering use type shall not be less than the type scheduled for that area.
5.3.3Type I light-duty wall covering shall not be installed in corridors, exits, lobbies, or other public circulation spaces.
○ Type I — light-duty (private offices, low-traffic rooms, ceilings)
● Type II — medium/heavy-duty (corridors, offices, public spaces)
○ Type III — heavy-duty (hospital/service corridors, food service)
1040
Default: 20 oz/linear yd
5.3.4The total weight of the wall covering shall not be less than the minimum for its use type: 13 oz/linear yd for Type I, 20 oz/linear yd for Type II, and 33 oz/linear yd for Type III.
6 Facing Material and Construction
NOTE The facing material determines durability, cleanability, appearance, and the applicable fire test; vinyl-coated fabric is the workhorse of commercial contract interiors, while textile, natural-fiber, cork, and digitally printed coverings serve decorative and specialty uses. (6.1)
NOTE Digitally printed and custom-printed coverings have grown significantly in market share; they are typically specified as performance equivalents to Type II vinyl with a custom graphic and carry the same fire and emissions requirements as the equivalent stock product. (6.2)
6.2.1The wall covering facing material shall be as scheduled for each area, and the submitted product shall meet the use type and fire class required for that area.
● Vinyl-coated fabric (woven or non-woven backing)
○ Vinyl film on non-woven backing
○ Textile / woven fabric face
○ Natural fiber (grasscloth, sisal, jute, seagrass)
○ Cork
○ Digitally printed (vinyl or non-woven substrate)
NOTE Natural-fiber coverings such as grasscloth typically achieve only Class C surface burning, or fail the room-corner test, and are therefore rarely acceptable in rated corridors; confirm the fire class against the location before specifying them. (6.3)
6.3.1Natural-fiber wall covering shall not be installed in rated corridors, exits, or other locations requiring Class A or Class B interior finish unless tested data demonstrates the required class for the specific product and mounting.
NOTE Backing porosity governs adhesive selection and seam behavior; woven backings, non-woven backings, paper backings, and acrylic backings each behave differently and shall be matched to the adhesive. (6.4)
○ Woven (osnaburg / scrim) backing
● Non-woven backing
○ Paper backing
○ Acrylic backing
6.5 Roll Width and Pattern
6.5.1Commercial wall covering shall be furnished in 54 in. nominal roll width; 27 in. residential and decorator widths shall not be substituted on commercial projects.
● 54 in. (commercial contract)
○ 27 in. (residential / decorator)
○ Special width (digital / large-format)
6.5.2The pattern match type and pattern repeat shall be identified on the cut-sheet submittal, and the quantity takeoff shall include the corresponding waste allowance.
○ Random match (no repeat)
● Straight match
○ Half-drop match
NOTE Straight-match goods are commonly under-ordered because the repeat consumes material at every drop; allow 10 to 15 percent waste for straight match and 15 to 25 percent for drop match, and require the cut-sheet before material is ordered. (6.6)
NOTE IBC 2021 Section 803 and NFPA 101 Chapter 10 require interior wall and ceiling finishes to meet a flame spread and smoke developed class (A, B, or C) based on occupancy, location, and sprinkler status; Class A is typically required in corridors, exits, and healthcare occupancies. (7.1)
NOTE Class A finish is defined as flame spread index 0 to 25 and smoke developed index 0 to 450 by ASTM E84; Class B is flame spread 26 to 75, and Class C is flame spread 76 to 200, each with smoke developed index not exceeding 450. (7.2)
NOTE In sprinklered buildings the code generally permits a one-class reduction in the required finish class for many locations; the applicable reduction depends on occupancy, location, and the adopted code edition. (7.3)
7.3.1The required interior finish class shall be confirmed against the adopted building code and the building's sprinkler status before the class is scheduled.
7.3.2Wall covering shall meet the interior finish class required by the adopted building code and the Life Safety Code for its occupancy and location, and shall not be less than the class scheduled.
○ Class A (FSI 0-25, SDI 0-450)
● Class B (FSI 26-75, SDI 0-450)
○ Class C (FSI 76-200, SDI 0-450)
NOTE The ASTM E84 tunnel test alone is not code-compliant for textile or expanded-vinyl wall coverings; IBC Section 803.5 requires these products to pass the NFPA 265 room-corner test (Method B) or the NFPA 286 room-corner test in addition to, or in lieu of, the tunnel test. (7.4)
7.4.1Textile wall coverings and expanded-vinyl wall coverings shall pass NFPA 265 (Method B) or NFPA 286 as required by IBC Section 803.5 and as accepted by the Authority Having Jurisdiction.
7.4.2The room-corner fire test shall be conducted with the specimen prepared and mounted per ASTM E2404, using the adhesive that will be used in the actual installation.
NOTE The fire test is a test of the assembly, not of the facing alone; switching to a different adhesive in the field changes the assembly and can void the listed result. (7.5)
7.5.1The adhesive used in the field shall be the same adhesive reflected in the product's NFPA 265 or NFPA 286 test report, and substitution of a different adhesive shall require retest or written manufacturer concurrence.
● NFPA 265 (Method B)
○ NFPA 286
○ Not applicable (non-textile, non-expanded product)
8 Low-Emitting Material Requirements
NOTE Healthcare and school specifications, and LEED v4 indoor environmental quality credits, commonly require third-party emissions certification of both the wall covering and the adhesive; specifying a product without requiring certification leads to substitution disputes at commissioning. (8.1)
8.1.1Where low-emitting materials are required, the wall covering and the adhesive shall be certified to UL 2818 or shall comply with the CDPH/EHLB Standard Method (CDPH 01350).
8.1.2Adhesive volatile organic compound content shall not exceed 50 g/L for waterborne acrylic adhesive unless a lower project-specific limit is scheduled.
● UL 2818 certified
○ CDPH 01350 (Standard Method v1.2)
○ None required
9 Adhesives and Seam Treatment
NOTE Adhesive shall be matched to the product weight, backing porosity, and substrate; some vinyl backings are incompatible with high-solids clay adhesives, which causes telegraphing or delamination, so the manufacturer's approved adhesive list governs. (9.1)
9.1.1The adhesive shall be a type recommended in writing by the wall covering manufacturer for the specific product, backing, and substrate.
9.1.2Adhesive for all commercial work shall contain a mildew inhibitor.
○ Clay-based (wheat-starch blend)
○ Acrylic
● Clay-acrylic blend
○ Type II waterproof (strippable) adhesive
NOTE Clay-acrylic adhesives have an open time of roughly 20 to 30 minutes and a set-up time of roughly 30 to 45 minutes; hanging shall stay within the open-time window to develop bond and avoid dry-back at seams. (9.2)
NOTE Open seams lift, discolor, and admit moisture if not immediately treated; seam sealer or contact cement locks the edges before the adhesive sets. (9.3)
9.3.1Wall covering shall be installed with butt seams or by the double-cut (overlap-and-trim) method.
9.3.2Seams shall be tight, flat, and free of overlap, gaps, or adhesive residue.
9.3.3Seam sealer or vinyl contact cement shall be applied at all butt joints within 5 to 10 minutes of hanging the adjacent drop.
9.3.4Seams shall not occur within 6 in. of an inside or outside corner.
● Double-cut (overlap and trim)
○ Butt joint
10 Substrate Preparation
NOTE Smooth-face and low-texture coverings telegraph every surface imperfection; the required gypsum finish level must be explicitly specified or it will not be provided, and the installed covering will reveal joints, fasteners, and trowel marks. (10.1)
10.2.1The substrate shall receive a minimum Level 4 gypsum finish, and shall receive a Level 5 finish where smooth-face or low-sheen wall covering is scheduled.
10.2.2The substrate shall be primed with an alkyd or acrylic wall covering primer and allowed to dry a minimum of 24 hours before installation.
● Level 4 (textured / heavy-emboss products)
○ Level 5 (smooth-face / low-sheen products)
● Acrylic wall covering primer
○ Alkyd wall covering primer
11 Moisture and Vapor Control
NOTE Non-permeable vinyl installed over below-grade or cold exterior walls traps moisture behind the facing and promotes mold; the wall assembly's vapor drive must be assessed before a non-permeable facing is accepted on such walls. (11.1)
11.1.1Non-permeable wall covering shall not be installed over assemblies subject to active inward vapor drive, including below-grade walls and uninsulated exterior walls, unless a vapor-drive analysis demonstrates acceptable performance.
11.1.2A vapor-permeable facing shall be specified where the wall assembly is subject to seasonal inward vapor drive and the analysis does not support a non-permeable facing.
● Non-permeable (interior partitions, dry conditions)
○ Vapor-permeable (exterior / below-grade assemblies)
NOTE Substrate moisture exceeding the wall covering manufacturer's limit causes adhesive failure, blistering, and mold; testing before installation is the only way to confirm the substrate is ready. (11.2)
11.2.1The substrate moisture content shall be verified by testing before installation begins.
11.2.2The substrate relative humidity shall not exceed 75 percent or the wall covering manufacturer's published limit, whichever is lower.
6080
Default: 75 percent RH
12 Environmental and Service Conditions
NOTE Wall covering shrinks if hung in conditions that differ from service conditions, opening seams after installation; material and space must be conditioned before and during installation. (12.1)
12.1.1Wall covering rolls shall acclimate in the installation space at service temperature and humidity for a minimum of 24 hours before installation.
12.1.2The installation space shall be maintained at the manufacturer's required temperature and humidity for a minimum of 48 hours before, during, and after installation until the adhesive has cured.
13 Installation
NOTE Wall covering installation depends on accurate run sequencing, correct adhesive application, controlled seam treatment, and clean termination at adjacent trades; these are addressed as discrete obligations below. (13.1)
13.1.1Wall covering shall be hung plumb, with the first drop established from a plumb line and not from a corner or door frame.
13.1.2Rolls shall be hung in sequence by run number, and reversed (booked) hanging shall be used only where required by the manufacturer to balance color shading.
13.1.3Excess adhesive shall be removed from the face and seams with a clean damp sponge immediately, before it dries on the surface.
13.1.4Wall covering shall be trimmed cleanly at outlets, switches, and penetrations, with cutouts tight to device plates.
NOTE Coordination of termination conditions with the base, ceiling, and protection trades is frequently left undefined and causes field conflicts; the stop conditions shall be specified rather than left to the field. (13.2)
13.2.1Wall covering shall terminate at the top of the resilient base and at the ceiling line.
13.2.3Inside and outside corner conditions shall be installed per the approved mockup, with the wall covering wrapped or terminated as shown and with no seam within 6 in. of the corner.
13.2.4Wall covering installation shall not begin until painting and ceiling-edge work that abuts the covering is complete, coordinated with Interior Painting. 14 Field Quality
NOTE The finished surface is the product of the assembly, and field acceptance verifies appearance, adhesion, seam integrity, and the absence of substrate telegraphing. (14.1)
14.1.1The finished wall covering shall be free of blisters, wrinkles, open or overlapped seams, gaps, color variation between drops, adhesive residue, and visible substrate telegraphing when viewed under finished lighting.
14.1.2Defective wall covering shall be removed and replaced; lifted seams and blisters shall be re-adhered only where the manufacturer's repair procedure produces an invisible repair, and shall otherwise be replaced.
15 Delivery, Storage, and Handling
NOTE Flexible wall coverings are damaged by crushing, edge denting, moisture, and temperature extremes, and dye-lot continuity depends on keeping run sequence intact through delivery and storage. (15.1)
15.1.1Wall covering shall be delivered in the manufacturer's original packaging with labels identifying product, color, dye lot, run number, and quantity intact.
15.1.2Rolls shall be stored standing on end or suspended, in a clean, dry, conditioned space, and shall not be stored on a damp floor or in direct sunlight.
15.1.3Material shall be inspected on delivery for color, dye lot, and run sequence, and any shading or sequence discrepancy shall be resolved before installation begins.
16 Warranty
NOTE Wall covering warranties cover material defects and, separately, installation workmanship; both are required because a failure may originate in the product, the adhesive bond, or the seam treatment. (16.1)
16.1.1The manufacturer shall warrant the wall covering against defects in material, including delamination and abnormal fading, for a minimum of five years from Substantial Completion.
16.1.2The installer shall warrant the installation against defects in workmanship, including seam separation and blistering, for a minimum of two years from Substantial Completion.
17 Spare Parts
NOTE Attic stock from the installed dye lot allows future repairs to match the field, which a later production run cannot guarantee; the quantity is set as a fraction of installed area. (17.1)
17.1.1The Contractor shall deliver attic stock of each wall covering type and color, from the installed dye lots, equal to not less than 5 percent of the installed area of that type.
17.1.2Attic stock shall be labeled with product, color, dye lot, and run number, and stored where directed by the Owner.
210
Default: 5 percent of installed area
