When installing large format tile with one side greater than 15 inches or 38 cm, the tolerance is reduced to 1/8 inch in 10 feet (3 mm in 3 m). ANSI A108.01 section 2.6.2
          b.Surfaces shall be clean and free of dust, oil, grease paint, tar, wax, curing compound, primer, sealer, form release agent, laitance, loosely bonded topping, loose particles and deleterious substance and debris which may prevent and reduce adhesion.
          c.Mechanically sand and scarify the substrate to completely remove all paint, loosely bonded topping, loose particles and construction debris.
          d.Neutralize any trace of strong acid and alkali.
          e.All substrates shall be dry. The moisture content shall not exceed 50 percent.
          f.Turn off all forced ventilation and radiant heating systems and protect work against drafts during installation and for a period of at least 72 hours, at 70 degrees F / 21 degrees C, after completion. Use indirect auxiliary heaters to maintain the temperatures in the area at the recommended workable level. Vent temporary heater to exterior to prevent damage to tile work from carbon dioxide build-up.
          g.Presswood, particleboard, chipboard, masonite, gypsum floor patching compounds, asbestos board, Luan and similar dimensionally unstable materials are not acceptable substrates.
          h.Before work commences examine the areas to be covered and report any flaw or adverse condition in writing to the architect and to the general contractor. Do not proceed with work until surfaces and conditions comply with the requirements indicated in ANSI A108 specifications.
          2.Concrete and Masonry:
          a.Concrete and Masonry surfaces must comply with ANSI A108.01 Section 3.2.
          b.All concrete substrates shall be at least 28 days old, completely cured and free of hydrostatic conditions, and/or excessive moisture problems.
          3.Plywood:
          a.Plywood subfloor and underlayment must comply with ANSI A108.01 section 3.4.
          4.OSB Panels:
          a.OSB panel is not a suitable surface for direct bonding ceramic tile. OSB is to be coated with Custom Building Products Multi-Surface Bonding Primer or RedGard Waterproofing and Anti-fracture membrane prior to the installation of ceramic tile.
          5.Backerboard Units Installation of Floors, Decks or Countertops:
          a.Cementitious Backerboard shall be installed per the guidelines in ANSI A108.11.
          6.Wall and Ceiling Installation

          7.Gypsum surfaces:
          a.Gypsum underlayment must have 2000 psi (13.8 MPa) compressive strength and be sealed prior to covering. For areas subject to water exposure, a waterproofing membrane is required.
          b.Gypsum Board shall be installed per the guidelines of ANSI A108.01 Section 3.5.
          8.Steel:
          a.Steel substrates shall be rigid, solidly fixed, dry, well sanded and free of dust, oil, grease, primer and all deleterious substances, which may prevent or diminish the bond. Consult with steel substrate manufacturer for acceptable cleaning methods. Mechanical scarification may result in loss of protective coatings and result in oxidation of steel substrates and is not an acceptable means of preparation.
          9.Tiling over old substrates:
          a.Old cement terrazzo, ceramic tile paver, quarry tile, vinyl and vinyl composition floor coverings other than cushion vinyl shall be sound, solidly in place, flawless, stripped or sanded, clean, free of dust, wax, grease, sealers, soap residue and all other deleterious substances which may prevent or reduce the adhesion. For further details, ANSI A108.01, Section 2.6.2.
 
          C.Install tile in accordance with appropriate ANSI A108 specifications and manufacturer's directions.
 
          D.Expansion joints, control joints, insulation joints, etc., must be located in compliance with TCA EJ171 and filled with appropriate materials.
          1.Joints must be carried through all layers of installation materials including tile, setting bed, mortar bed and reinforcing wire. Refer to TCNA Handbook, EJ171 and ANSI AN-3.8 for details on placement, size and specifications of materials.) .
 
          E.Install grout in accordance with Grout ANSI A108.10 specifications and manufacturer's directions.
 
          F.Install elastomeric tile sealant around sinks, tubs and showers and where tile meets tile or another surface. Surfaces should be clean, dry and free of all contamination. Maximum joint width and depth should not exceed 1/4 inch (6 mm).
          ** NOTE TO SPECIFIER ** Protective sealers are available for various surfaces. Contact the manufacturer for recommendations. Delete entirely if sealer is not required.
 
          G.Pre-Seal or use grout release on tile when required. Seal grout, stone and unglazed tile with an appropriate sealer 48 - 72 hours after grout application at 70 degrees Fahrenheit (21 degrees C) as needed.
 
          3.4PROTECTION
 
          A.Protect finished installation under provisions of section 01500 [01 50 00]. To avoid damage to finished tile work, schedule floor installations to begin only after all structural work, building enclosure, and overhead finishing work are completed.
 
          B.Keep all traffic off finished tile floors until they have fully cured. Builder shall provide up to 3/4 inch (19 mm) thick plywood or OSB protection over non-staining, breathable covering to protect floors after installation material has cured. Covering the floor with polyethylene or plywood in direct contact with the floor may adversely affect the curing process of grout and latex/polymer fortified Portland cement mortars.
 
          C.Due to the slow rate of Portland cement hydration and strength development at low temperatures, protect installations exposed to these conditions from traffic for longer than normal periods. Protect newly installed exterior adhered veneer installations from direct exposure to rain for 7 days at 70 degrees F (21 degrees C). Protection applies to the substrate, the installation of adhesives and joint grouts, post-installation rain and temperature protection until suitable cure, and the storage and handling of the cladding material. Extend period of protection of tile work at lower temperatures, below 60 degrees F (15 degrees C), and at high relative humidity greater than 70 percent relative humidity (R.H.) due to retarded set times of mortar/adhesives. For every 18 degrees F (10 degrees C) below 70 degrees F (21 degrees C) installation materials will take twice as long to cure. Large format tiles require longer curing periods in cooler temperatures. Keep all traffic off the finished work until full cure. Suitable protection is to be included in the scope of work. Each component must reach a proper cure prior to installing the subsequent installation product.
 
          D.Tent / shade and heat areas that will be subjected to the elements or freezing temperatures during installation and cure periods.
 
          E.Keep floors installed with epoxy adhesive closed to traffic for 24 hours at 70 degrees F (21 degrees C), and to heavy traffic for 48 hours at 70 degrees F (21 degrees C) unless instructed differently by manufacturer. Use kneeling boards, or equivalent, to walk/work on newly tiled floors.
 
          F.To Replace or restore work of other trades damaged or soiled by work under this section.
