Quarry tile for floors of [_____] shall contain an abrasive aggregate uniformly embedded into face surface of tile. Abrasive aggregate shall be fused aluminum oxide or other rustproof aggregate of comparable hardness having a grain size smaller than 1.18 mm 16 mesh and larger than 150 micrometers 100 mesh (US Standard Sieve Sizes). Tile provided shall contain grains in the surface between 50 percent and 150 percent, on the average by count, and as much aggregate as the approved samples. 2.1.1.2 Quarry Tile Trim Units TCA Hdbk standard grade. Provide cove base around perimeter of floors and at vertical projections through floors. Provide bullnose trim around depressions in floors. Provide rounded internal and external corners with 13 mm 1/2 inch minimum radius using appropriate matching corner units. 2.1.2 Chemical-Resistant Mortar and _Grout NOTE: Insert other items or areas subject to heat beyond 54 degrees C (130 degrees F). Provide chemical-resistant grout for quarry tile floors [in [_____]]. Provide a compatible system of setting bed and joint material from a single source. In addition to the chemical resistance and physical properties specified, mortar and grout shall conform to the following: 2.1.2.1 Furan Mortar ASTM C 395. Either two-component or three-component is acceptable. 2.1.2.2 Furan Grout ASTM C 658. 2.1.2.3 Epoxy ASTM C 395 for setting tile grouted with furan. 2.1.2.4 Epoxy Mortar and Grout ANSI/CTI A108/A118/A136.1. PART 3 EXECUTION 3.1 PREPARATION Do not start tile work until rough-in for plumbing, heating, ventilating, air conditioning, and electrical work has been completed and tested [and membrane waterproofing has been installed and tested]. Protect the work of other trades in area where tile work is to be done. 3.1.1 Preparation of Tile NOTE: Factory-coated units should be specified when experience indicates that application of wax in the field is unsatisfactory. [Factory] coat with hot paraffin wax to produce a thin continuous film on the face surfaces only of quarry tile units to be installed and grouted with furan. Apply wax in such manner that it will not get on edges or backs of tile. Handle tile in a manner that will prevent waxed surfaces of units from touching the backs or edges of other units. Remove tile with wax on edges or backs from the job. Verify that wax used is acceptable to grout manufacturer. With flatback or serrated back tile use 6 mm 1/4 inch square notched trowel with notches on 13 mm 1/2 inch centers. 3.1.2 Preparation of Concrete Floors for Setting Beds NOTE: Where tile is to be installed, concrete slabs should not have air entrainment or other additives in the mix, nor sealers or curing compounds applied without specific approval of mortar and grout manufacturer. Slabs should have steel trowel and fine broom finish and be free of laitance. In case of any question on condition of slab, it should be tested for bondability with a Dillon Dynamometer and show a tensile bond of not less than 300 psi. These requirements should be incorporated in Section 03 31 00.00 10 CAST-IN-PLACE STRUCTURAL CONCRETE Before tile is applied, test structural floor for levelness or uniformity of slope by water. Fill, level, and retest areas as required to meet tolerances specified in Section A-3 of ANSI/CTI A108/A118/A136.1 and retest. When specified levelness or uniformity of slope is obtained, prepare floors for setting bed in accordance with ANSI/CTI A108/A118/A136.1. Free floors of sealers, coatings, oil, dirt, and dust. Prepare floors before application of resin mortar in accordance with printed instructions and recommendations of the mortar manufacturer. 3.2 INSTALLATION Except where specified otherwise herein, apply materials in accordance with manufacturer's printed instructions, including recommended safety requirements. 3.2.1 Setting Bed Using a plain (not serrated) trowel, apply a continuous setting bed of chemical-resistant mortar, not less than 3 mm 1/8 inch thick. Apply only over a floor area that can be tiled during "open time" of mortar. Place tile into setting bed and tap lightly to a true plane. Level tile as it is placed. Maintain uniform tile joints of 6 mm 1/4 inch minimum and 10 mm 3/8 inch maximum width. Allow the setting bed to cure sufficiently to anchor tile in place, but not less than 24 hours, at a floor temperature of not less than 16 degrees C 60 degrees F. When furan setting bed is used, first install a glass reinforced asphalt membrane. With flatback or serrated back tile use trowel with 6 mm 1/4 inch square notches on 13 mm 1/2 inch centers. 3.2.2 Tile Joints After the setting bed has cured, fill tile joints with chemical-resistant grout. Spread grout on surface of tile and work it into the open joints with a trowel. Fill joints flush with top surfaces of tile. Remove excess grout with one pass of a trowel or squeegee pulled diagonally across joints in order to prevent imperfect filling and low joints. Immediately fill voids, pinholes, and depressions with additional grout. Protect completed joints from dampness. Permit grout to harden for not less than 72 hours. Flush cure joints with tile edges; contour depression shall not exceed 1.2 mm for 6 mm 3/64 inch for 1/4 inch wide joints or 2 mm for 10 mm 1/16 inch for 3/8 inch wide joints. Sealants for expansion joints provided by the grout manufacturer shall be compatible with grout and setting mortars. Completely fill joints with no back up foam or rope. Install joints maximum 6000 mm 20 feet on center above slab around room peripheries and columns but not at drains. 3.2.3 Tile Installation Install and grout tile with water cleanable tilesetting and grouting epoxy in accordance with ANSI/CTI A108/A118/A136.1 . 3.3 CLEANING After grout has hardened, scrub and wash tile surfaces with steam or hot water to melt wax coating and remove excess grout. Remove remnants of grout with wide-bladed paint scraper or other tool that will not damage tile. Rinse tile with clean warm water applied with a flat sponge. Remove excess water from floor, and leave floor dry when work is completed. Remove tile from which surface grout cannot be removed without damage to tile. Remove damaged tile and provide new tile. 3.4 PROTECTION Cover finished tile floors with clean building paper before permitting foot traffic on them. Place board walkways on floors that are to be continuously used as passageways by workmen.
