A. General: Install in accordance with ANSI A108 Standard for Ceramic Tile installation and TCA Handbook. Cut and fit

tiles neatly around corners, fittings, and obstructions. Perimeter tile to be minimum half tile. Chipped, cracked, and split tile

and edges, not acceptable. Make joints even, straight, plumb and of uniform width to tolerance +/- 1/16" (1.5mm) over 8ft.

(2400mm). Install divider strips at junction of flooring and dissimilar materials.

B. Thin Bed Method (Rear Mesh Mounted Glass Mosaics): The LATICRETE adhesive shall be prepared by mixing one of the

following systems:

LATICRETE® 254 Platinum Multipurpose Thin-Set Mortar, or

LATAPOXY® 300 Epoxy Adhesive (Best option for continuous wet areas and exterior areas)

Apply prepared mortar to the masonry surface to be tiled with a notched trowel to work installation materials into good

contact with the tile substrate. A trowel having "V" or square notches approximately 3/16" x 3/16" (4mm x 4mm) is

recommended. In addition, the adhesive shall be placed onto the backside of each sheet of glass mosaic tile with the flat side

of the notched trowel immediately before placement of sheet into the freshly troweled adhesive on the surface to receive the

tile work. Spread only as much adhesive as can be covered in 20-30 minutes, or while mortar/adhesive surface is still wet and

tacky. Tile shall then be aligned to show uniform joints and then allowed to set until firm. Excess adhesive must then be

cleaned from the surface of the tile with a wet cloth or sponge while the adhesive is fresh.

C. Thick Bed Method (Vertical Surfaces, Pre-float Method): Trowel weather resistant, latex-Portland cement scratch/plumb

coat mortar over wire lath, concrete or masonry; Float surface of scratch coat plumb/true and set until firm.

ga.(1.5mm), galvanized, welded reinforcing wire fabric complying with ANSI A108.1(A-2 Materials, A4.1.5.3) and

ASTM A 185 over mortar; Place additional latex-Portland cement thick bed mortar over wire fabric and compact mortar

by tamping with flat trowel; Screed mortar bed level and provide correct slopes to drains; Spread latex-Portland

cement mortar with flat trowel over surface of "green"/fresh mortar bed as a slurry bond coat approximately 1/16in./1.5

mm thick; Apply slurry bond coat to back of glass tile, mosaic, paver, trim unit or threshold and place each piece/sheet

while slurry bond coats are wet and tacky; Beat with a hardwood block or rubber mallet to level/imbed tilework before

mortar bed takes initial set; Clean excess mortar/adhesive from tile surfaces.

E. Thick Bed Mortar (Horizontal Surfaces; Directly Bonded):

1. Verify 1 in./25 mm nominal bed thickness has been allowed;

2. Apply latex-Portland cement mortar with flat trowel as a slurry bond coat approximately 1/16in./1.5mm thick over clean

concrete slab or load bearing LATICRETE waterproof membrane; Place latex-Portland cement thick bed mortar over

slurry bond coat while bond is wet and tacky; Omit reinforcing wire fabric and fully compact bed by tamping;

F. Grout/Pointing Joints: (Rear Mesh Mounted Tiles using the 2 step method of tile installation) Verify grout joints are free of

dirt, debris or tile spacers; follow manufacturer recommendations for minimum cure time prior to grouting. Sponge or wipe

dust/dirt off tile faces and remove water standing in joints; Apply grout release to face of absorptive, abrasive, non-slip or

rough textured glass tile, pavers, bricks, or trim units that are not hot paraffin coated to facilitate cleaning; Pack joints full

and free of voids/pits with rubber grouting float; "Squeegee" excess grout from tile faces using edge of rubber float and

across tile faces/joints to remove remaining grout film and allow tile work to dry. Hardened grout film or haze should be removed

within 24 hours. Cleaning epoxy grouts - follow manufacturer’s specific guidelines for cleaning epoxy grout installations. Epoxy

film or haze must be removed within 24 hours with a detergent wash; do not use acid cleaners on epoxy grout less than 7 days old.

No acids should be used for cleaning glass mosaic tile work.

1. chemical resistant, water cleanable grouting epoxy as per Paragraph 2.5 D or F or 2.8 H (for interior installation of

virtually any type of tile, with grout joints 1/16in./1.5mm wide and larger);

2. latex-portland cement sanded floor grout as per paragraph 2.8 Q for joint widths 1/16in/1.5mm to 3/8in./10mm)

3. latex-portland cement unsanded grout as per Paragraph 2.8 Q (for interior installations of absorbent/non-vitreous type

tiles, soft glazed tiles and soft/polished marble tile with joints widths 1/8 in./3 mm or less;

G. Expansion and control joints: Provide control or expansion joints in width and depth as located and detailed on contract

drawings and conform to architectural details. Existing joints in concrete sub-floors to carry through to surface of tile work.

restraining surfaces such as perimeter walls, curbs, columns, wall corners, etc., and directly over cold joints and control

joints

in structural surfaces. Locate interior expansion joints a maximum of 24' x 24' (8m x 8m). Locate exterior expansion joints a

maximum 16' x 16' (5m x 5m). Rake or cut through tile setting bed to substrate expansion joints.

correct all defective work. Defective work includes, without limitation, tiles broken in normal abuse due to deficiencies in

setting bed, loose tiles or grout, and all other defects which may develop as a result of poor workmanship or defective

materials.

A. Clean excess mortar from surface with water as work progresses. Perform cleaning while mortar is fresh and before it

hardens on surfaces. Take care to not contaminate joints while cleaning prior to grouting. Sponge and wash tile diagonally

across joints. Polish with clean dry cloth. Remove grout haze following recommendation of mortar additive and epoxy

manufacturer. Do not use acids for cleaning. Upon completion, remove all surplus materials and leave premises broom clean.

A. Protect finished installation under provisions of Section (01500.) (01535.) Close areas to other trades and traffic until tile

being installed has set firmly. Keep traffic off horizontal Portland cement thick bed mortar installations for at least 72 hours

before flood testing or filling installation with water. Extend period of protection of tilework at lower temperatures (below

work of other trades damaged or soiled by work under this section.
