3. DESCRIPTION
TEC
®
Ultimate Large Tile Mortar is a high performing, polymer-modified, full-contact
(full-coverage) mortar for installing ceramic, porcelain and natural stone tile. It
is ideal for use as a medium bed mortar for heavy and large format tile in both
interior and exterior applications. (maximum mortar thickness of
3
⁄4 " (19 mm) after
the tile is embedded). It can also be used in standard thin-set applications. As
a medium bed mortar it significantly reduces the need for back-buttering. It also
provides extended open time and has non-sag/non-slump characteristics for wall
and floor applications.

Suitable Substrates
When properly prepared, suitable substrates include:
• Cured concrete, cured mortar beds, brick and masonry (interior and exterior
installations)
• APA Grade Trademarked Exposure 1 Plywood [Underlayment grade or better,
two layers, 1
1
⁄8 " (28 mm) total minimum thickness for joists 16" (40 cm) o.c.,
interior floors only].
• Gypsum wallboard (dry interior wall areas only)
• Water resistant gypsum wallboard (i.e.: greenboard, interior walls only, dry to
intermittent water exposure only)
• Cementitious backer units (CBU) or glass mat backerboard
• Existing ceramic tile and natural stone, provided existing flooring is well-bonded
to an approved substrate.
• Vinyl composition tile, asphalt tile, linoleum or non-cushioned vinyl sheetgoods
provided such surfaces are single layered, well-bonded to an approved
substrate and properly prepared.
• Adhesive residue (except tacky or pressure-sensitive adhesive). Mechanically
remove the adhesive to expose at least 80% of the concrete surface.
Random specks of adhesive and the appearance of a brown surface stain are
acceptable.
Substrate Preparation
All substrates must be dry, structurally sound with maximum deflection per
industry standards of
L
⁄360 for ceramic tile installations and
L
⁄720 for natural stone
installations; and free from oil, grease, dust, paint, sealers or concrete curing
compounds. All contaminants must be removed prior to installation of tile. Surface
protrusions and tile glazes shall be removed by sanding, scraping or scarifying.
After preparation, remove all dust by vacuuming.
Notes: Vinyl asbestos tile or any substrate containing asbestos must not be
sanded, scored or scarified because of the potential health hazard of
breathing dust. Any substrate containing asbestos must be handled in
accordance with existing EPA regulations. Contact your local EPA office.
Expansion joints must be provided in the tile work over all construction,
control and expansion joints in the backing and where backing materials
change. Follow ANSI A108.01 Section 3.7 Requirements for Expansion Joints.
Maximum variations in all substrates must not exceed
1
⁄4 " in 10 ft.
(6 mm in 3 m) and
1
⁄16 " in 1 ft. (1.6 mm in 0.3 m) from the required plane.
For large non-level, interior surfaces use TEC
®
EZ Level
®
Premium Self
Leveling Underlayment. For exterior surfaces or smaller areas of rough
uneven substrates, use a scratch coat of TEC
®
Ultimate Large Tile Mortar
up to
1
⁄4 " (6 mm) thick. Allow to cure to walkable hardness before applying
mortar bond coat.
Storage
Store in cool, dry location. Do not store open containers.
