1.6  PROJECT/SITE CONDITIONS:

	A.	Environmental Requirements:  Maintain spaces in which flooring work is to be performed between 70 and 90 degrees F at the floor level during the time work is performed and for at least 48 hours after the work is completed.  Maintain a minimum temperature of 55 degrees F thereafter.  Provide adequate ventilation to remove moisture and fumes from the area.

1.7  SEQUENCING AND SCHEDULING:

The additional materials of each color shall be from the same lot as the materials installed.  

PART 2:  PRODUCTS

2.1  MATERIALS:

	A.	Vinyl‑Composition Tile:  Tile shall be resistant to alkali, grease, and oils and shall be sufficiently dense to withstand loads of 50 psi when tested by ASTM F 142.  See Section 09999 ‑ Color Schedule for required colors.
		1.	Requirements:  Color and pattern of tile shall be uniformly distributed throughout the thickness of the tile.  Resilient flooring materials of the same type, pattern, and color shall be of the same production run and shall be so marked.  Variations in shades and off‑pattern matches between containers will not be acceptable.  Flooring in any one continuous area shall be from the same lot and have the same shade and pattern.  Installed materials shall match samples.  The Contracting Officer reserves the right to approve or reject tile on the basis of color or pattern.

	B.	Adhesives:  Adhesives and other application materials shall be those as recommended specifically by the tile manufacturer.  Smoking and the use of open flames and other immediate sources of ignition are strictly prohibited in the area where adhesives are being used or spread.  Conspicuous signs regarding "NO SMOKING OR OPEN FLAME" shall be posted in the area of spread adhesives.

	C.  Water Emulsion Floor Wax:  As instructed by flooring manufacturer.

	D.  Crack Filler:
		1.  Concrete Floor Surfaces:  Non‑shrinking cement mortar.
   	2.  Wood Floor Surfaces:  Plastic wood filler.

	E.	Lining Felt:  Semi‑saturated or fully saturated, 15 lb asphalt felt, as instructed by flooring manufacturer.

	F.  Underlayment:  Latex type as instructed by flooring manufacturer.

	G.  Edging Strips:  Beveled vinyl plastic.

	H.  Accessories:  Standard products of the manufacturer of the flooring.

PART 3:  EXECUTION

3.1  PREPARATION:

	A.	Surface Preparation:  Floor surfaces shall be clean, thoroughly dry, smooth, firm, sound, and free from springiness, oil, paint, wax, dirt, curing compounds, or any other damaging material.  Work shall not be started until any surface defects have been corrected.  
		1.	Curing Compounds:  Only resin or asphalt‑type curing compounds over concrete will be acceptable.  Remove others by sanding, sandblasting or grinding.

		2.	Concrete Floor Surfaces:  Grind ridges or other uneven surfaces smooth.  Cut out and fill cracks 1/16 inch wide or wider with crack filler specified.  Provide latex underlayment to fill the remaining holes, cracks, and depressions, and for smoothing, leveling, or feather‑edging the concrete.  Prime chalky or dusty surfaces with a primer recommended by the flooring manufacturer after cleaning and removal of loose particles.

		3.	Moisture Test for Concrete Floors:  After concrete floor surfaces have been cleaned, spread small patches of adhesive to be used in several locations in each room and allow to dry or "set" overnight.  If the "set" adhesive can be peeled easily from the floor surface, the floor is not sufficiently dry.  Repeat the test until the adhesive adheres properly.  When the adhesive adheres tightly to the floor surface, apply the tile.

		4.	Wood Floor Surfaces:  Fill knot holes, cracks wider than 1/8 inch, and holes larger than 1/4 inch in diameter with a crack filler as specified for this application.  Plane, scrape, or sand smooth ridges or other uneven surfaces.  Set nail heads.  Provide lining felt over wood floor surfaces if recommended by the floor covering manufacturer.  Carefully cut felt around vertical surfaces, and butt seams in felt.  Stagger cross seams.  Apply adhesives in accordance with the manufacturer's written instructions.  Roll the felt into the adhesive with a three‑section roller weighing not less than 100 lb in order to remove air bubbles and secure complete adhesion.

3.2  INSTALLATION/APPLICATION:

	A.	General:  Rooms receiving resilient flooring shall be closed to traffic during installation and for 48 hours after installation is completed.  Apply flooring and accessories in accordance with the manufacturer's installation procedure.  

	B.	Primer:  Concrete slabs in contact with the ground or over unventilated crawl spaces shall be primed with cutback type primer, if so recommended by the flooring manufacturer.  Primer shall be worked into the surface of the concrete, using the minimum quantity that will cover the surface completely with a nonabsorptive base.  Primer shall be allowed to become thoroughly dry before adhesive is applied.  Cut‑back adhesive only shall be applied to primed concrete floor surfaces.  Apply either cutback or emulsion adhesives to underlayment and felt‑covered wood floor surfaces.

	C.	Adhesives:  Adhesives shall be as specified for the specific application.  Apply adhesives according to the adhesive manufacturer's printed directions, unless specified or directed otherwise.  The area covered by one application of adhesive shall not exceed the maximum working area recommended by the manufacturer.  Flooring shall be installed within recommended time limits.  If adhesive films over or dries, it shall be removed and the area recoated.

	D.	Flooring:  Apply flooring in the patterns indicated.  Start in the center of the room or area, and work from the center towards the edges.  Keep tile lines and joints square, symmetrical, tight, and even; and keep each floor in a true, level plane, except where indicated as sloped.  Vary edge width as necessary to maintain full‑size tiles in the field, but no edge tile shall be less than one‑half the field tile size, except where irregular shaped rooms make it impossible.  Floor tile shall be laid with "grain" of tile running parallel to the short dimension of the room.

	E.	Cutting:  Cut flooring to and fit around all permanent fixtures, built‑in furniture and cabinets, pipes, and outlets.  Cut edges, fit, and scribe to walls and partitions after field flooring has been applied.

	F.	Edge Strips:  Provide edging strips where flooring terminates at points higher than the contiguous finished flooring, except at doorways where thresholds are provided.  Secure plastic strips with adhesive.

	G.	Tolerances:  Concrete subfloor tolerances shall not be over 1/8 inch in 10 feet in any direction.

3.3  CLEANING:

	A.	Requirements:  Immediately upon completion of the installation in a room or area, clean flooring and adjacent surfaces with a cleaner to remove surplus adhesive.  No sooner than 5 days after installation, wash all flooring with a non‑alkaline cleaning solution, rinse thoroughly with clear cold water, and finish.  Apply two coats of polish and buff each coat to an even luster with an electric polishing machine.  Clean bases but do not polish.

3.4  PROTECTION:

	A.	Requirements:  From the time of laying until acceptance, protect flooring from damage.  Areas which cannot be permanently barred from traffic until building acceptance shall be covered with plain, undyed, unsaturated kraft or building paper with taped joints.  Remove and replace defects which develop, such as damaged, loose, broken, or curled tiles prior to final inspection.

PART 4:  MEASUREMENT AND PAYMENT

4.1  METHOD OF MEASUREMENT:

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

4.2  BASIS OF PAYMENT:

	A.	Payment:  No direct payment for the work described under this section will be made.  The Contractor shall include consideration for this item in the bid price for other items of the Contract.
