PART 3 - EXECUTION

3.1 EXAMINATION

A. Examine substrates, areas, and conditions where tile will be installed, with Installer present, for compliance with requirements for installation tolerances and other conditions affecting performance of installed tile.

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.

3.2 PREPARATION

A. Fill cracks, holes, and depressions in concrete substrates for tile floors installed with trowelable leveling and patching compound specifically recommended by tile-setting material manufacturer.

B. Blending: For tile exhibiting color variations, use factory blended tile or blend tiles at Project site before installing.

C. Field-Applied Temporary Protective Coating: If indicated under tile type or needed to prevent grout from staining or adhering to exposed tile surfaces, precoat them with continuous film of temporary protective coating, taking care not to coat unexposed tile surfaces.

3.3 CERAMIC TILE INSTALLATION

A. Comply with TCA's "Handbook for Ceramic Tile Installation" for TCA 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 TCA installation methods, specified in tile installation schedules, and apply to types of setting and grouting materials used.

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. 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.

TILING 093000 - 6

1. For tile mounted in sheets, make joints between tile sheets same width as joints within tile sheets so joints between sheets are not apparent in finished work.

2. Where adjoining tiles on floor, base, walls, or trim are specified or indicated to be same size, align joints.

3. 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.

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

1. Ceramic Mosaic Tile: 1/16 inch (1.6 mm).

2. Glazed Wall Tile: 1/16 inch (1.6 mm).

G. 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.

H. Grout Sealer: Apply grout sealer to cementitious 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.

I. Install cementitious backer units and treat joints according to ANSI A108.11 and manufacturer's written instructions for type of application indicated.

3.4 pressed cement terazzo tile Installation

A. All installations of Tectura Designs Cement Terrazzo Tile shall comply with the appropriate installation method as depicted in the current edition of the Tile Council of North America Handbook for Ceramic, Glass, and Stone Installation. The Architect or other design professional shall select which methods to be specified. All Specifications must also conform to local codes, ordinances, trade practices, and climate conditions.

B. All Materials used for installation of Tectura Designs Cement Terrazzo Tile must comply with the appropriate ANSI 118 and/or ISO 13007 standards and specifications. Setting materials manufacturer’s printed installation instructions are to be followed in every instance. Materials NOT recommended are A-118-1 Dry-Set Mortars and A-136.1 Organic Adhesives. Only ANSI A-118.4 and ISO C2S1 mortars or better are recommended

1. A minimum of 95 percent thin-set coverage is recommended on the back of the terrazzo tile. The corners of the tile must have good mortar support to prevent cracking. Back buttering is recommended to reach these requirements.

C. Contact your selected setting materials manufacturer for all installation questions.

1. When setting Tectura Designs Epoxy Terrazzo Tile, please contact your setting materials manufacturer as the setting materials for these tiles will most likely change.

2. When using Membranes of any kind, please contact your setting materials manufacturer as the setting material will most likely change.

D. Appropriate ANSI A-108 installation specifications that correspond with the selected TCNA Installation Method are to be followed. This includes Substrate and Surfaces inspections, Location and Frequency of EJ171 Movement Joint Guidelines, Placement Techniques, and Grouting Procedures.

093000 - 7 TILING

1. Minimum recommended grout joint width is 1/8”

E. Applied Initial Protectant - Stone Floor Protector:

1. Contact your selected grouting materials manufacturer for installation questions

2. It is not required that the terrazzo tile be resealed prior to or after grouting.

3. When using a heavy pigmented grout, it’s recommended to use a grout release prior to grouting. A test area is recommended to ensure the grout release was adequately applied.

4. If a slight grout haze occurs, it can be effectively removed from the tile by using an eraser pad with water and or neutral cleaner.

5. A floor buffer might be recommended to assist in cleaning.

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 and bonded securely to substrate.

B. Do not install tile or setting materials over waterproofing until waterproofing has cured and been tested to determine that it is watertight.

3.6 CLEANING AND PROTECTING

A. 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. Remove temporary protective coating by method recommended by coating manufacturer and that is acceptable to tile and grout manufacturer. Trap and remove coating to prevent drain clogging.

B. 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.

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

D. Before final inspection, remove protective coverings and rinse neutral protective cleaner from tile surfaces.
