INSTALLING A NEW QUARRY TILE FLOOR TO MATCH HISTORIC QUARRY TILE


PART 1---GENERAL

1.01 SUMMARY

    A.   This procedure includes guidance on installing new quarry
         tile to replace lost or severely damaged portions of
         historic quarry tile, or to enlarge or alter an area of
         existing/historic quarry tile floors.  GENERALLY, THIS
         WORK SHOULD BE ACCOMPLISHED BY A EXPERIENCED CONTRACTOR.

    B.   For additional information on the preservation,
         maintenance, repair and replacement of quarry tile, see
         09310-02-S.

    C.   See 01100-07-S for general project guidelines to be used
         along with this procedure.  These guidelines cover the
         following sections:

PART 3---EXECUTION

3.01 EXAMINATION

    A.   Examine the substrate and the conditions under which tile
         is to be installed.  Do not proceed with the work until
         unsatisfactory conditions have been corrected.

3.02 ERECTION, INSTALLATION, APPLICATION

    A.   Match the historic character and pattern of the quarry
         tile in all spaces containing, or contiguous with,
         existing quarry tile.

    B.   Provide applicable tile installation method for substrate
         and performance as described below and complying with TCA
         "Handbook for Ceramic Tile Installation".

    C.   Comply with applicable ANSI Standard installation
         specifications as follows:

         1.   Setting Bed of Portland Cement Mortar:  ANSI A108.1

         2.   Dry-Set Mortar Floor Tile:  ANSI A108.5.

    D.   Joint Pattern:  

         1.   Unless otherwise indicated, lay tile in grid
              pattern.  

         2.   Align joints when adjoining tiles on floor, base
              and trim are the same size.  

         3.   Layout tile work and center tile fields both
              directions in each space or on each wall area as
              applicable.  Adjust to minimize tile cutting.
              Provide uniform joint widths.

    E.   Expansion and Control Joints:

         1.   Provide where indicated and as recommended by TCA
              Method EJ411.  In no case provide control joints
              less frequently than:

              a.   At any point where tile abuts projections such
                   as columns, curbs and pipes.

              b.   Directly over joints in the structure
                   substrate.

              c.   Joints to be not less than 1/4" wide.

         2.   Install removable divider strips of the same depth
              as the finished tile system, including setting bed.
              Remove strips after grouting and curing operations.
             
    F.   Edge Strip - Threshold:  Where quarry tile terminates,
         except at vertical surfaces, and where finish surface
         will be in same plane with other adjoining floor
         material,  provide metal edge strip, otherwise provide
         marble threshold of required profile, except as otherwise
         indicated for specific projects.

    G.   Coverage:  Extend tile work into recesses and under
         equipment and fixtures, to form a complete covering
         without interruptions, except as otherwise indicated.
         Terminate work neatly at obstructions, edges and corners
         without disruption of pattern or joint alignment, and use
         applicable trim and special shape as required.

    H.   Fitting:  Accurately form intersections and returns, and
         use applicable trim and special shapes as required.
         Perform cutting 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 and fixtures so
         that plates, collars or covers overlap tile.

    I.   Setting Beds:  Provide applicable setting bed types as
         indicated.  Handle and apply proprietary mortar materials
         complying with instructions of manufacturer.

    J.   Setting Tile:  Set dry quarry tile in place, and tamp
         level and even with adjacent tile and within required
         tolerances.  Use appropriate spacers to obtain a straight
         and uniform joint.  Provide trim and special shapes, and
         accessories as required.

    K.   Grouting:  Provide applicable grout types as required.
         Handle and apply grout complying with instructions of
         manufacturer.  Start grouting after setting bed mortar or
         bond coat has cured and tiles are firm and secure in-
         place.

3.03 ADJUSTING/CLEANING

    A.   Clean grout and setting materials from face of tile while
         materials are workable.  Leave tile face clean and free
         of all foreign matter.

    B.   Use of acid or caustic materials to clean tile is not
         acceptable.

    C.   Leave finished installation clean and free of cracked,
         chipped, broken, unbonded, or otherwise defective tile
         work.

3.04 PROTECTION

    A.   Apply a protective coat of neutral protective cleaner to
         completed tile surfaces.

    B.   Protect installed tile work with Kraft paper or other
         heavy covering during the construction period to prevent
         damage and wear.

    C.   Prohibit all foot and wheel traffic from using tiled
         floors for at least 3 days, preferably 7 days.

    D.   Before final inspection, remove protective coverings and
         wash tile surfaces clean.
