    	4.  Smoke development rating.
    	5.  Flame spread rating.
    	6.  Fuel contribution rating.
    	7.  Width of material.

	C.	Samples:  Submit [5] samples (8 x l0‑1/2 inches) of each fabric, pattern, and color selected to be used on this project, bearing identifying labels for approval.  

1.4  QUALITY ASSURANCE:

	A.  Failure Criteria:  Not limited to the following:
		1.  Shrinking which produces seam gaps.
   	2.  Fabric loosening from substrate.
   	3.  Vinyl delaminating from backing material.

1.5  DELIVERY, STORAGE, AND HANDLING:

	A.	Delivery and Storage:  Store rolls flat, supported off the floor in a heated and ventilated area away from construction procedures.

1.6  PROJECT/SITE CONDITIONS:

	A.  Environmental Conditions:
	1.	Permanent lighting is desirable before vinyl installation.  If not available, the Contractor shall provide temporary lighting of equal brilliance to the permanent lights.
    	2.	Heat in the area of application shall be maintained between 60 and 80 degrees F during installation and for 24 hours thereafter.

PART 2:  PRODUCTS

2.1  MATERIALS:

	A.  Vinyl‑Coated Fabric:

   	Pattern   Manufacturer  Fabric  Weight/lin. yd.    Weight/sq. yd.

(Written for individual project.)

1.	ab	Colors:  See Section 09999 ‑ Color Schedule.
   	2.	Material Backing:  Closely woven, pre‑shrunk, mildew‑proofed cotton fabric.
    	3.	Vinyl Coating:  Completely fused to the fabric backing.

4.	ab    	Width:  54 inches minimum.
    	5.	Fire Rating:  Vinyl fabric shall bear maximum Underwriters' Laboratories, Inc. ratings in accordance with ASTM E 84 as follows:
				Flame spread       ‑ 25
				Fuel contributed   ‑ 10
				Smoke developed    ‑ 10

	B.	Adhesive:  Type and brand as recommended by manufacturer of vinyl‑coated fabric wall covering.  Adhesion to substrate shall be in accordance with ASTM D 751.

PART 3:  EXECUTION

3.1  EXAMINATION:

	A.	Verification of Conditions:  All joints shall be smooth with face of wallboard, with all nail heads recessed and filled and sanded smooth with face of board.
		1.	Pattern and Color:  Verify that they are satisfactory and as ordered.  Examine patterned material for repeat in design, if any.
		2.	Roll Tag:  If hanging more than one roll, check information tag on roll for roll number and if roll is in one piece.  Use rolls in numbered sequence.
		3.	Adhesive:  See instructions on container for hanging and surface sizing instructions.

3.2  INSTALLATION:

	A.	General:  Use panels in exact order as they are cut from the roll.  Trim selvage of each panel with a straight edge on cutting table deep enough to assure color conformity.  Cut material on table to required length allowing additional length for patterns with repeat marks.

	B.	Procedures:  Vinyl wall covering panels may be installed in either of the following manners:

1.	ab	Table trim with a straight edge as noted and butt panels on the wall.
   	2.	Overlap panels on wall and make seams by double cutting through both sheets.  Care must be taken NOT to cut into the substrate surface.  After the cut is made, remove the face strip only.  Clean the side of the seam that has the adhesive on the face.  Don't wash the clean side.  Dry the cleaned area.  Remove the cut strip from under the wall covering and then set the seam by hand, scraper or roller.  Finished seams shall be straight, tight and clean.

	C.	Seams:  Vertical joints shall occur at least 2 inches from inside and outside corners.  Critically examine each two seams when completed.  Additional trimming may be necessary.  Scribe fit to all butted irregular surfaces.

	D.	Adhesive:  Stir paste thoroughly before use and maintain temperature between 60 and 80 degrees F while using.  Do not thin paste with water or add other ingredients to the paste.  Apply adhesive by roller or brush in an even coat over the entire backing of the vinyl.  Avoid having excess adhesive at the seams when double cutting.  Remove excess adhesive from a seam before making the next seam.  Use a sponge or cloth dampened with clean, warm water, but not wringing wet.  Wipe clean with dry towel.  On deep grains use a fine nylon bristle brush.

	E.	Air Bubbles:  Smooth fabric to hanging surface with stiff bristled brush or flexible broad knife, to eliminate air bubbles.

	F.	Piecing:  Fill in over doors and windows as encountered with panels cut in consecutive order from the roll.

	G.	Problems:  Contact local manufacturer's representative for instructions on any unusual installation problem, or if after installing 3 panels, there is any question of color or pattern matching.

	H.	Finished Product:  Final wall product shall be secure, smooth, clean, all air bubbles eliminated and in good contact with substrate, without gaps or overlaps and with a minimum of seams.

	A.	Units:  The work described in this section will not be measured for payment.

4.2  BASIS OF PAYMENT:
