which penetrate flooring material, has been completed.

1.8 MAINTENANCE:

A. Manufacturer\'s Maintenance Data and Instructions: Upon completion

triplicate, of the flooring manufacturer\'s printed instructions for
maintenance methods and products for each type of flooring material.

B. Extra Materials: Upon completion of work, deliver additional tile

maintenance. Furnish tile in original boxes, properly marked, with
colors in the same proportions as installed materials; 1/2 carton
minimum of each color of tile. The additional materials of each color
shall be from the same lot as the materials installed.

[PART 2: PRODUCTS]{.underline}

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]{.underline}

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]{.underline}

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.
