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

along with this procedure. These guidelines cover the
1. Historic Structures Precautions
3. Quality Assurance
4. Delivery, Storage and Handling
5. Project/Site Conditions
6. Sequencing and Scheduling
7. General Protection (Surface and Surrounding)
These guidelines should be reviewed prior to performing

installation to be within tolerances as follows:
1. Variation from a true plane not to exceed 3/16" in
10'-0", any direction but not more than 3/8" for
2. Variation in offset of edge-to-edge alignment of
adjoining tile not to exceed 1/32".
A. Product Data: Submit manufacturer's technical
information and installation instructions for all
materials required, except bulk materials. Include
certifications and other data as may be required to show
compliance with these specifications.
B. Samples: Submit samples of each type, color, pattern and
texture of tile required, not less than 18" square on
plywood or hardboard backing and grouted as required.
Also, submit a full-size sample of each tile accessory.
Samples will be reviewed for color, pattern, and texture
C. Design Data/Test Reports/Certificates: Furnish Master
Grade Certificate for each type of tile complying with
1.05 QUALITY ASSURANCE
A. Standards: Comply with the provisions of the following,
except to extent more detailed or more stringent
requirements are indicated.
B. Manufacturing Standards:
1. When using setting and grouting materials
manufactured under TCA license, include
identification and formula number on each
2. Provide materials obtained from only one source for
each type of tile and color to minimize variations
in appearance and quality.
1.06 PROJECT/SITE CONDITIONS
A. Environmental Requirements: Maintain a temperature of
not less than 50 degrees F. during tile installation and

2. Edges: Square edges, ground after firing.
3. Color: Matching existing historic quarry tile (clean and uncoated units) as selected from colors standard with manufacturer, if possible. If matching tile is unavailable as a standard option, custom slip coat coloring may be accepted if price acceptable and approved by RHPO.
B. Trim and Special Shapes, General: Provide tile trim and
special shapes with rounded external corners at openings,
exposed edge termination and other like conditions, and
as specified for installation method, of same material
and finish as field tile.
C. Accessories: Metal Edge Strips.
D. Mortar and Grout:
1. Setting Bed Mortar Materials: Complying with ANSI
2. Dry-Set Mortar: Proprietary factory proportioned,
pre-mixed and packaged mortar dry pre-mixture of
portland cement and additives complying with ANSI
A118.1 and TCA Formula 759.
3. Commercial Portland Cement Grout: Proprietary
factory proportioned, pre-mixed and packaged grout
dry pre-mixture of portland cement and additives.
Grout pre-mixture to have properties to be non-
shrink, increase moisture resistance, non-staining
and non-promoting of bacteria growth. Colors to be
as selected from colors standard with manufacturer.
Color pigments to be resistant to fading, acidity
and alkali. Maximum color pigment to cement ratio
by weight to be 1:10.
4. Water: Clean and free of deleterious materials
which would impair strength, bond or appearance.
E. Miscellaneous Materials: Joint Sealing Materials:
Complying with sealant specifications.
A. Mortar and Grout Mixes:
1. Setting Bed Mortar: Portland cement mortar mix
complying with ANSI A108.1.
2. Proprietary Mortar and Grout: Mix materials
complying with instructions of manufacturer.
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, coloring, 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
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

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

that plates, collars or covers overlap tile.
I. Setting Beds: Provide applicable setting bed types as
indicated. Handle and apply proprietary mortar materials
