3. DESCRIPTION
TEC
®
Contractor Grade Self Leveling Underlayment is a pumpable/pourable
cement based, self-leveling underlayment designed for use over a variety of
substrates. The resulting smooth finished surface is ideal for the installation of all
types of floor covering, including carpet, ceramic or natural stone tile, resilient,
laminate flooring and wood flooring (for interior dry area use only).
Note: All surfaces must be primed with TEC
®
Multipurpose Primer before
application of TEC
®
Contractor Grade Self Leveling Underlayment.

Suitable Substrates
When properly prepared, suitable substrates include:
• Concrete
• Ceramic or quarry tile (well-bonded)
• Exterior grade plywood
• Oriented Strand Board (OSB)
Substrate Preparation
It is required that all surfaces be structurally sound and free from any
contaminants that may inhibit bond, including oil, grease, dust, loose or peeling
paint, sealers, floor finishes, or curing compounds, etc. Minimum tensile bond
strength of 72 psi (0.5 MPa) is required. Substrate temperature should be a
minimum of 43°F (6°C) during application and air temperature maintained above
50° (10°C). DO NOT cover existing building expansion or control joints. Provide
control joints where specified. Create
1
⁄8
" to
1
⁄4
" (3-6 mm) wide gaps where
self-leveling underlayment abuts walls, columns, and fixtures by installing a
self-sticking foam weather stripping tape or damp sand (vacuum up sand after
self-leveling underlayment has cured). Plug all floor openings, gaps and cracks
and install termination dams to prevent any seepage. Surfaces must be primed
with TEC
®
Multipurpose Primer prior to installation of TEC
®
Contractor
Grade Self Leveling Underlayment. See Primer label for application instructions.
TEC
®
Contractor Grade Self Leveling Underlayment can be installed over green
concrete with RH of 95% or less. For moisture sensitive floor coverings refer
to the finished floor manufacturer's specifications on moisture limitations.
Remediation of excessive moisture conditions must be addressed prior to the
installation TEC
®
Contractor Grade Self Leveling Underlayment. To reduce moisture
vapor emissions to an acceptable level, use TEC
®
The LiquiDAM
®
Penetrating
Moisture Vapor Barrier (see product data sheet for details).
TEC
®
Contractor Grade Self Leveling Underlayment is not recommended
for use over adhesives and/or residues.
Single Layer of Exterior Grade Plywood or Oriented Strand Board (OSB)
with Lath: Wood subflooring must be securely fastened with screw type or ring
shank nails and adhesive. Installations of exterior grade plywood or OSB (APA
Rated Sturd-I-Floor OSB, Exposure 1 or better) require
3
⁄4
" (19 mm) single layer
minimum thickness on bridged floor joists up to 24" (60 cm) on center, with
a maximum deflection of
L
⁄
360
of the span. Allow a gap of
1
⁄8
" to
1
⁄4
" (3-6 mm)
between sheets of plywood or OSB. Long edges of subfloor must be tongue and
groove or supported by bridging between floor joists. Use suitable TEC
®
surface
preparation products (PerfectFinish™, VersaPatch
®
, Fast-Set Deep Patch) to plug
all floor openings, gaps and cracks and install termination dams to prevent any
seepage. Prime the floor and allow it to dry to a clear film. Next, staple
1

galvanized diamond metal or plastic lath to the floor overlapping 2" (5 cm)
at seams. Staple every 6" (15 cm) around the perimeter and overlaps, and every
8" (20 cm) in the field of the lath. Install TEC
