compliance with requirements for installation tolerances and other conditions affecting

performance of the Work.

1. Verify that substrates for setting tile are firm; dry; clean; free of coatings that are

incompatible with tile-setting materials, including curing compounds and other

substances that contain soap, wax, oil, or silicone; and comply with flatness tolerances

required by ANSI A108.01 for installations indicated.

2. Verify that concrete substrates for tile floors installed with thinset mortar comply with

surface finish requirements in ANSI A108.01 for installations indicated.

a. Verify that protrusions, bumps, and ridges have been removed by sanding or

grinding.

3. Verify that installation of grounds, anchors, recessed frames, electrical and mechanical

units of work, and similar items located in or behind tile has been completed.

4. Verify that joints and cracks in tile substrates are coordinated with tile joint locations; if

not coordinated, adjust joint locations in consultation with Architect.

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

3.2 PREPARATION

A. Fill cracks, holes, and depressions in concrete substrates for tile floors installed with thinset

mortar with trowelable leveling and patching compound specifically recommended by tile-

setting material manufacturer.

B. Where indicated, prepare substrates to receive waterproofing by applying a reinforced mortar

bed that complies with ANSI A108.1A and is sloped 1/4 inch per foot toward drains.



C. Blending: For tile exhibiting color variations, verify that tile has been factory blended and

packaged so tile units taken from one package show same range of colors as those taken from

other packages and match approved Samples. If not factory blended, either return to

manufacturer or blend tiles at Project site before installing.

3.3 CERAMIC TILE INSTALLATION

A. Comply with TCNA's "Handbook for Ceramic, Glass, and Stone Tile Installation" for TCNA

installation methods specified in tile installation schedules. Comply with parts of the

ANSI A108 series "Specifications for Installation of Ceramic Tile" that are referenced in TCNA

installation methods, specified in tile installation schedules, and apply to types of setting and

grouting materials used.

1. For the following installations, follow procedures in the ANSI A108 series of tile

installation standards for providing 95 percent mortar coverage:

a. Tile floors in wet areas.

b. Tile floors consisting of tiles 8 by 8 inches or larger.

B. Extend tile work into recesses and under or behind equipment and fixtures to form complete

covering without interruptions unless otherwise indicated. Terminate work neatly at

obstructions, edges, and corners without disrupting pattern or joint alignments.

C. Accurately form intersections and returns. Perform cutting and drilling of tile without marring

visible surfaces. Carefully grind cut edges of tile abutting trim, finish, or built-in items for

straight aligned joints. Fit tile closely to electrical outlets, piping, fixtures, and other

penetrations so plates, collars, or covers overlap tile.

D. Provide manufacturer's standard trim shapes where necessary to eliminate exposed tile edges.

E. Where accent tile differs in thickness from field tile, vary setting-bed thickness so that tiles are

flush.

F. Jointing Pattern: Lay tile in grid pattern unless otherwise indicated. Lay out tile work and center

tile fields in both directions in each space or on each wall area. Lay out tile work to minimize

the use of pieces that are less than half of a tile. Provide uniform joint widths unless otherwise

indicated.

1. Where adjoining tiles on floor, base, walls, or trim are specified or indicated to be same

size, align joints.

2. Where tiles are specified or indicated to be whole integer multiples of adjoining tiles on

floor, base, walls, or trim, align joints unless otherwise indicated.

G. Joint Widths: Unless otherwise indicated, install tile with the following joint widths:

1. Porcelain Tile: 1/8 inch.

H. Lay out tile wainscots to dimensions indicated or to next full tile beyond dimensions indicated.



I. Expansion Joints: Provide expansion joints and other sealant-filled joints, including control,

contraction, and isolation joints, where indicated. Form joints during installation of setting

materials, mortar beds, and tile. Do not saw-cut joints after installing tiles.

1. Where joints occur in concrete substrates, locate joints in tile surfaces directly above

them.

J. Stone Thresholds: Install stone thresholds in same type of setting bed as adjacent floor unless

otherwise indicated.

K. Metal Edge Strips: Install where exposed edge of tile flooring meets carpet, wood, or other

flooring that finishes flush with or below top of tile and no threshold is indicated.

L. Grout Sealer: Apply grout sealer to grout joints in tile floors according to grout-sealer

manufacturer's written instructions. As soon as grout sealer has penetrated grout joints, remove

excess sealer and sealer from tile faces by wiping with soft cloth.

3.4 TILE BACKING PANEL INSTALLATION

A. Install panels and treat joints according to ANSI A108.11 and manufacturer's written

instructions for type of application indicated. Use modified dry-set mortar for bonding material

unless otherwise directed in manufacturer's written instructions.

3.5 WATERPROOFING INSTALLATION

A. Install waterproofing to comply with ANSI A108.13 and manufacturer's written instructions to

produce waterproof membrane of uniform thickness that is bonded securely to substrate.

B. Allow waterproofing to cure and verify by testing that it is watertight before installing tile or

setting materials over it.

3.6 ADJUSTING AND CLEANING

A. Remove and replace tile that is damaged or that does not match adjoining tile. Provide new

matching units, installed as specified and in a manner to eliminate evidence of replacement.

B. Cleaning: On completion of placement and grouting, clean all ceramic tile surfaces so they are

free of foreign matter.

1. Remove grout residue from tile as soon as possible.

2. Clean grout smears and haze from tile according to tile and grout manufacturer's written

instructions but no sooner than 10 days after installation. Use only cleaners recommended

by tile and grout manufacturers and only after determining that cleaners are safe to use by

testing on samples of tile and other surfaces to be cleaned. Protect metal surfaces and

plumbing fixtures from effects of cleaning. Flush surfaces with clean water before and

after cleaning.



3.7 PROTECTION

A. Protect installed tile work with kraft paper or other heavy covering during construction period to

prevent staining, damage, and wear. If recommended by tile manufacturer, apply coat of neutral

protective cleaner to completed tile walls and floors.

B. Prohibit foot and wheel traffic from tiled floors for at least seven days after grouting is

completed.
