PART 3 EXECUTION
3.1 INSPECTION
A. Do not proceed with the work of this section until conditions detrimental to the proper and timely completion of the work have been corrected in an acceptable manner.
3.2 INSTALLATION
A. Surface Preparation:
1. Insure slab is free of curing compounds or when used, mechanical scarifying is necessary.
2. Verify slopes are down to drains as shown on drawings.
a. Comply with TCNA F131 at slabs with slopes as shown on drawings, and/or be sure there is proper sloping to all floor drains.
b. Comply with TCNA F132 at slabs requiring a setting bed for slopes or leveling and TCNA:
1) F112: For a mortar bed over slab on grade where no bending stresses
occur.
2) F111: For mortar bed over structural floors subject to bending and deflection.
3) F121: For a mortar bed over a waterproof membrane.
c. Setting Bed Thickness:
1) 1-1/4" maximum thickness of setting bed on the concrete substrate. Screed and compact to achieve uniform slope.
4. Movement Joints at Setting Bed:
a. Provide control, isolation, expansion, and contraction joints according to movement joint designs and install according the TCNA Handbook for Ceramic Tile Installation.
b. Locate movement joints:
1) At 20 to 25 feet in each direction, for interior locations.
2) At tile abutting perimeter walls, dissimilar floors, pipes, and columns.
3) Over cold joints and saw-cuts in the slab.
c. Extend joints through the setting bed to the concrete substrate equal in width to the tile grout joints.
d. Provide approved solid neoprene filler and approved polysulfide caulking.
5. Movement Joints at Epoxy Mortar and Grout:
a. Provide for expansion and control joints where specified.
b. Do not cover or bridge any expansion joints with epoxy.
c. Plan installation so tiles line up on one side of the control or expansion joints.
d. Protect tilework with metal strips along both edges of structural building expansion joints.
e. Insert sealant manufacturer s specified compressible bead and sealant for expansion and control joints.
6. Mixing Epoxy Mortar:
a. Wear rubber gloves and avoid skin contact during mixing, application, and cleaning.
b. Mix epoxy components in units according to manufacturer s instructions for proper curing.
7. Epoxy Mortar Application:
a. Follow tile-setter's conventional procedures, laying quarry tile in epoxy mortar bond coat and in pattern indicated with straight lines and uniform joints 3/8" wide.
b. Use the recommended notched trowel according to manufacturer s instructions with sufficient depth to ensure proper epoxy mortar transfer, covering 100 percent of the tile back.
c. Using the flat or straight edge of the trowel, apply a thin, pressure-applied coat to the substrate. Follow immediately with additional material, then comb the surface using the notched side of the trowel to achieve an even setting bed.
d. The entire substrate should be covered, leaving no bare areas between the ridges.
e. Set tiles dry.
f. Do not spread more epoxy mortar than can be covered immediately with ceramic tiles.
g. Place tiles firmly into position with a slight twisting motion to ensure good contact with the epoxy mortar.
h. Follow immediately with proper and thorough beat-in to flatten the ridges or notches into a continuous bed, allowing at least 25 percent of the thickness of each tile to be embedded into the epoxy mortar to minimize air bubbles from reaching the surface and causing pinholes during grouting.
i. Make all alignments or adjustments immediately following beat-in.
j. Remove smudges from the tile face immediately with a clean sponge and water.
k. Do not disturb, grout or walk over tiles for at least 24 hours.
8. Epoxy Grout Application:
a. Tile surfaces shall be clean, dry, and free of any debris.
b. Joints shall be clean and free of excess setting material, standing water, dust,
and foreign substances.
c. Maintain surface temperature between 60 degrees F and 90 degrees F.
d. Prepare and mix epoxy according to manufacturer s instructions.
e. Grout and clean in small areas.
f. Using a hard rubber float, force the grout into the joints in a continuous manner,
leaving it flush with the tile edge.
g. Joints shall be well-compacted and free of voids and gaps.
h. Fill the joints with the maximum amount of grout possible, except expansion control joints.
i. Thoroughly remove excess epoxy from the face of the tile before it loses its plasticity or begins to set.
j. Clean tiles immediately after applying each unit of epoxy.
k. Do not disturb, grout or walk over tiles for at least 24 hours.
9. Protection:
a. Before allowing foot traffic over finished tile surfaces cover the work with a layer of heavy polyethylene film, building paper, or other accepted protective covering.
