3. DESCRIPTION
TEC
®
Floor Mud is a Portland cement-based mortar designed for thick setting
beds under ceramic or quarry tiles. When mixed to a dry consistency, TEC
®
Floor
Mud allows maximum compaction during tamping.

" (19 mm) to 9" (27 cm),
with a dry-pack consistency
• Interior or exterior use
• Ideal for creating shower bases
• Easy mixing. Just add water or TEC

Suitable Substrates
When properly prepared, acceptable substrates include:
• Cured concrete floors
• Over plywood substrates (with a waterproof membrane)
• Adequately designed wood frame floor systems; see Tile Council of North
America (TCNA) Handbook.
Substrate Preparation
Surface must be clean, dry, hard and free from dirt, loose particles, wax, sealers,
curing compounds, grease, paint, efflorescence and any foreign materials that
will inhibit adhesion. Floors must be structurally sound, free of movement and
dimensionally stable. All installations must conform to ANSI A108.1. Smooth
concrete surfaces must be scarified. Concrete surface must be brought to a
saturated surface dry (SSD) condition with clean potable water. All excess water
must be removed. All materials should be stored at 40°F (4°C) to 80°F (27°C) for
24 hours prior to installation.
NOTE: It is the responsibility of the installer/applicator to ensure the suitability of the product for its
intended use.
Storage
Store in cool, dry location. Do not store open containers.
Shelf Life
Maximum of 1 year from date of manufacture in unopened package.
Limitations
• Do not use over gypsum underlayment, hardwood, OSB, particle board or parquet
flooring.
• Do not use under moisture sensitive floor coverings.
• Do not overwater. Mix to a dry consistency.
Cautions
Read complete cautionary information printed on product container prior to use.

5. INSTALLATION INSTRUCTIONS
Mixing
Use cool, clean, potable water for mixing. Always use clean tools and mixing
containers. TEC
®
Acrylbond
®
AMA acrylic mortar additive can be used in place of
water. Add just enough dry mix to the liquid, approximately 2.5-3 qts. (2.4-2.8 L)
per 50 lbs. (22.68 kg), to produce a dry-pack consistency. Too much liquid will
cause the mortar to have reduced strength. The consistency and workability
should be such to allow maximum compaction during tamping. Bucket life is
approximately one hour. Warmer temperatures will reduce the bucket life.
Application
Apply only to surfaces that are frost free and above 40°F (4°C) and below 100°F
(38°C) within 24 hours of application and 72 hours thereafter. Installation must
conform to the current specifications in ANSI A108.5 and the TCNA Handbook for
Ceramic Tile Installations.
Floors requiring reinforcement: When installing mud beds requiring
reinforcement, place wire mesh reinforcement in the center of the mortar bed;
reinforcement should not butt against vertical surfaces. Apply a slurry bond coat
and install floor mud to desired thickness.
Shower receptors, steam rooms, and wet areas: When installing TEC
®
Floor Mud in a shower receptor, steam room or wet areas requiring waterproof
membranes, TEC
®
Floor Mud must be tamped and sloped towards drain at
1
⁄
4
"
(6 mm) per foot and have a waterproof membrane and flanged drain installed
prior to TEC
®
Floor Mud installation. Refer to TCNA B414, TR418 and SR613.
HydraFlex™ Waterproofing Crack Isolation Membrane on top of the cured mortar
bed greatly reduces mold and mildew growth in the shower floor.
