from underlayment surface before application of floor covering.

D. Comply with manufacturer's written instructions for installing floor tile.

E. Lay out floor tiles from center marks established with principal walls, discounting minor offsets, so tiles

at opposite edges of room are of equal width. Adjust as necessary to avoid using cut widths that equal

less than one-half tile at perimeter.

1. Lay tiles square with room axis.

F. Match floor tiles for color and pattern by selecting tiles from cartons in the same sequence as

manufactured and packaged, if so numbered. Discard broken, cracked, chipped, or deformed tiles.

1. Lay tiles with grain direction alternating in adjacent tiles (basket-weave pattern).

G. Scribe, cut, and fit floor tiles to butt neatly and tightly to vertical surfaces and permanent fixtures

including built-in furniture, cabinets, pipes, outlets, and door frames.

H. Extend floor tiles into toe spaces, door reveals, closets, and similar openings. Extend floor tiles to center

of door openings.

I. Maintain reference markers, holes, and openings that are in place or marked for future cutting by

repeating on floor tiles as marked on substrates. Use chalk or other nonpermanent, nonstaining marking

device.

J. Install floor tiles on covers for telephone and electrical ducts, building expansion-joint covers, and similar

items in finished floor areas. Maintain overall continuity of color and pattern between pieces of tile

installed on covers and adjoining tiles. Tightly adhere tile edges to substrates that abut covers and to

cover perimeters.

3.1 EXAMINATION

Examine substrates, areas, and conditions, with Installer present, for compliance with requirements for

maximum moisture content, alkalinity range, installation tolerances, and other conditions affecting carpet

tile performance. Examine carpet tile for type, color, pattern, and potential defects.

A. Concrete Subfloors: Verify that concrete slabs comply with ASTM F 710 and the following:

1. Slab substrates are dry and free of curing compounds, sealers, hardeners, and other materials that

may interfere with adhesive bond. Determine adhesion and dryness characteristics by performing

bond and moisture tests recommended by carpet manufacturer.

2. Subfloor finishes comply with requirements specified in Section 033000 "Cast-in-Place Concrete"

for slabs receiving carpet.

3. Subfloors are free of cracks, ridges, depressions, scale, and foreign deposits.

B. For wood subfloors, verify the following:

1. Underlayment surface is free of irregularities and substances that may interfere with adhesive

bond or show through surface.


D. Prior to delivering carpet, building shall be fully enclosed including doors and windows, and air-

conditioning and heating system shall have been in continuous, ongoing operation for 14 days. Verify

environmental conditions before delivering carpet to project site.

E. Proceed with installation only after unsatisfactory conditions have been corrected.

3.2 PREPARATION

A. Sequence carpet installation to minimize construction activities on installed carpet. Complete painting

prior to carpet installation.

B. General: Comply with CRI 104, Section 6.2, "Site Conditions; Floor Preparation," and with carpet tile

manufacturer's written installation instructions for preparing substrates indicated to receive carpet tile

installation. Floors shall be clean, dry, and all cracks, holes, and gaps shall be filled with an approved

floor patching compound. Floors to receive carpet shall be smooth, clear of obstructions, and broom

cleaned before installation begins. Floor temperature must be minimum 65 degrees F. for 72 hours prior

to installation, night and day during installation, and for 72 hours after the completion of installation. A

minimum of 50 degrees F. shall be maintained thereafter. The Carpet Installer shall promptly notify the

General Contractor and Architect of any floor conditions that affect the carpet installation.

Finishing underlayment panel joints—Use patching compound sparingly to fill wide joints, repair any surface voids and correct joint lippage (panel edge sitting above or below the floor plane). Carefully fill joints wider than 1/32 in. and any surface imperfections with only enough material to infill void—do not feather. Correct joint lippage by applying patching compound to low side only and feathering to level. Allow compound to dry completely (90 min. minimum), then lightly sand or scrape, taking care not to scuff panel surface; use a flat blade to scrape away any excess material. Remove dust, dirt and debris from underlayment surface before application of floor covering.


C. Installer to verify alkalinity level of substrate conforms to carpet manufacturer requirements. Installer to

test to verify pH level is between 5 and 9 or as required by carpet manufacturer.

D. Use trowelable leveling and patching compounds, according to manufacturer's written instructions, to fill

cracks, holes, depressions, and protrusions in substrates. Fill or level cracks, holes and depressions 1/8

inch (3 mm) wide or wider and protrusions more than 1/32 inch (0.8 mm) unless more stringent

requirements are required by manufacturer's written instructions.

E. Remove coatings, including curing compounds, and other substances that are incompatible with

adhesives and that contain soap, wax, oil, or silicone, without using solvents. Use mechanical methods

recommended in writing by carpet tile manufacturer.

F. Clean metal substrates of grease, oil, soil and rust, and prime if directed by adhesive manufacturer.

Rough sand painted metal surfaces and remove loose paint. Sand aluminum surfaces, to remove metal

oxides, immediately before applying adhesive.

G. Broom and vacuum clean substrates to be covered immediately before installing carpet tile. After

cleaning, examine substrates for moisture, alkaline salts, carbonation, or dust.

H. Proceed with installation only after unsatisfactory conditions have been corrected.

3.3 INSTALLATION

A. Fasten underlayment to subfloor with minimum 1/4 in. crown chisel point staples, hot-dipped galvanized

ring shank nails or corrosion-resistant screws. Fastener length should be approximately equal to

combined thickness of underlayment and subfloor. Fasteners should not penetrate through subfloor; long

fasteners that penetrate the floor joists may compromise the ability of the subfloor to expand and contract

uniformly with natural variations in temperature and humidity. Critical lighting situations should be

considered when determining panel layout.

B. Begin underlayment fastening where three panels intersect. Affix fasteners along joints in a zipper pattern

at 1 in. o.c., 1/4 in. from panel edge. Install fasteners at 4 in. o.c. in the field of panels. When using

pneumatic tools, apply sufficient pressure on gun to prevent the tool from bouncing. Set pneumatic tool

pressure to drive fasteners flush or slightly below underlayment surface. To prevent fastener heads from

telegraphing through resilient floor covering, do not countersink more than 1/16 in. below surface. Fasten

one panel at a time. Begin at one end and fan out across the panel.

C. Finishing underlayment panel joints—Use patching compound sparingly to fill wide joints, repair any

surface voids and correct joint lippage (panel edge sitting above or below the floor plane). Carefully fill

joints wider than 1/32 in. and any surface imperfections with only enough material to infill void—do not

feather. Correct joint lippage by applying patching compound to low side only and feathering to level.

Allow compound to dry completely (90 min. minimum), then lightly sand or scrape, taking care not to

scuff panel surface; use a flat blade to scrape away any excess material. Remove dust, dirt and debris

from underlayment surface before application of floor covering.

D. General: Comply with CRI 104, Section 14, "Carpet Modules," and with carpet tile manufacturer's

written installation instructions.

E. Installation Method: Glue down; install every tile with full-spread, releasable, pressure-sensitive

adhesive.

F. Maintain dye lot integrity. Do not mix dye lots in same area.


G. Cut and fit carpet tile to butt tightly to vertical surfaces, permanent fixtures, and built-in furniture

including cabinets, pipes, outlets, edgings, thresholds, and nosings. Bind or seal cut edges as

recommended by carpet tile manufacturer.

H. Approved edge details for leveling at material transitions or edge trims shall be executed at all areas

where floor covering materials change, or at any carpet edge that does not abut a vertical surface more

than 2" high.

I. Extend carpet tile into toe spaces, door reveals, closets, open-bottomed obstructions, removable flanges,

alcoves, and similar openings.

J. Maintain reference markers, holes, and openings that are in place or marked for future cutting by

repeating on finish flooring as marked on subfloor. Use nonpermanent, nonstaining marking device.

K. Install pattern parallel to walls and borders.

L. Use edge strips, as indicated in Part 2 at all carpet to VCT, Concrete or tile intersections. Do not use

saddle or T-seams in doorways.


A. Perform the following operations immediately after installing carpet tile:

1. Remove excess adhesive, seam sealer, and other surface blemishes using cleaner recommended by

carpet tile manufacturer.

2. Remove yarns that protrude from carpet tile surface.

3. Vacuum carpet tile using commercial machine with face-beater element.

B. Protect installed carpet tile to comply with CRI 104, Section 16, "Protecting Indoor Installations."

C. Protect carpet tile against damage from construction operations and placement of equipment and fixtures

during the remainder of construction period. Use protection methods indicated or recommended in

writing by carpet tile manufacturer.

uniform paint finish, color, and appearance.

D. Apply coatings to produce surface films without cloudiness, spotting, holidays, laps, brush marks, roller

tracking, runs, sags, ropiness, or other surface imperfections. Produce sharp glass lines and color breaks.


E. Scheduling Coating Applications: Apply first coat to surfaces that have been cleaned, pretreated, or

otherwise prepared for coating as soon as practicable after preparation and before subsequent surface

deterioration.

1. The number of coats and film thickness required are the same regardless of application method.

Apply additional coats of final coat if required to provide minimum coating thickness as specified.

Do not apply succeeding coats until previous coat has cured as recommended by manufacturer. If

sanding is required to produce a smooth, even surface according to manufacturer's written

instructions, sand between applications.

2. Omit primer over metal surfaces that have been shop primed and touchup painted except as

required in the paint schedule.

3. If undercoats, stains, or other conditions show through final coat of paint, apply additional coats

until paint film is of uniform finish, color, and appearance. Give special attention to ensure that

edges, corners, crevices, welds, and exposed fasteners receive a dry film thickness equivalent to

that of flat surfaces.

4. Allow sufficient time between successive coats to permit proper drying. Do not recoat surfaces

until paint has dried to where it feels firm, and does not deform or feel sticky under moderate

thumb pressure, and until application of another coat of paint does not cause undercoat to lift or

lose adhesion.
