3. DESCRIPTION
TEC
®
Fiber Reinforced Underlayment is a pumpable/ pourable, cement-based
product that can be used as a high performing 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.
Note: All surfaces must be primed with TEC
®
Multipurpose Primer before
installing Fiber Reinforced Underlayment.

2
) per 24 hours, RH 95% or lower]
•
Thickness ranges from
1
⁄16 " (1.6 mm) up to 1½" (38 mm) depth in a single pour
• Self-drying formula
• Walkable in 2-4 hours; install flooring as soon as 6 hours

®
project points
• Recommended for use with radiant heating systems
*See section 5 for wood substrates installation guidelines.

Suitable Substrates
When properly prepared, suitable substrates include:
• Concrete • Ceramic, porcelain, or quarry tile
• Cement or epoxy terrazzo • Cement backerboard
• Exterior grade plywood • Oriented Strand Board (OSB)
• VCT or full glued down, non-cushioned vinyl sheet goods
• Existing tongue and groove wood flooring
• Gypsum substrates–minimum tensile bond strength 72 psi (0.5 MPa)
Substrate Preparation
General: All surfaces must be structurally sound and free from any contaminants
that may inhibit bond, including oil, grease, dust, loose or peeling paint, floor
finishes or waxes, etc.
Surfaces must be primed with TEC
®
Multipurpose Primer prior to installation of
TEC
®
Fiber Reinforced Underlayment. See Primer label for application instructions.
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 dynamic (moving) control joints or cracks. Provide 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 static (non-moving) cracks and
install termination dams to prevent any seepage.
Concrete: TEC
®
Fiber Reinforced Underlayment can be installed over new (“green”)
concrete with a maximum of 95% RH or 15 lbs per 1000 ft
2
(0.07 kg/m
2
) per
24 hours. However, when installing 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
®
Fiber Reinforced Underlayment. To reduce moisture vapor
emissions to an acceptable level, use TEC
®
The LiquiDAM
®
Penetrating Moisture
Vapor Barrier prior to application of TEC

Multipurpose Primer and TEC

Reinforced Underlayment see TEC

product data sheet for details).
A successful application to concrete requires evaluation of the concrete surface
and preparation to address any conditions that would prevent a good bond.
Following are the four conditions you need to check for. Check for Condition 1 on
the entire concrete surface. Check for Conditions 2 through 4 on several areas,
typically every 100 square feet (9.3 m
2
) on applications of 1000 square feet (93 m
2
)
or less and every 500 square feet (46.5 m
2
) on larger applications. Once you have
completed the preparation method, always re-check to confirm the method worked.
Shot blasting is one of the most effective methods of removing a wide variety
of contaminants, or laitance (weak concrete surface material) from concrete. A
shot blast machine will remove sealers, coatings, curing compounds and other
contaminants quickly and effectively, leaving behind a proper surface ready to
receive the primer and underlayment. Thickness of surface removal must be deep
enough to eliminate penetrated contaminants or laitance.
CONDITION 1: Surface coatings and/or contamination such as gypsum plaster,
joint compound, or adhesive.
Evaluation: Look at the surface and note the type and location of the surface
contamination.
Preparation: First scrape off any lumps and loose material. Then use an
appropriate cleaning method for the type of contamination. Examples include:
• Coatings or paints – Application over coatings is acceptable if they are well
bonded and achieve a minimum of 72 psi (0.5 MPa) tensile bond strength.
Coating surface must be free from any contaminants that may inhibit bond.
Poorly bonded or peeling coatings must be removed by mechanical method.
• Gypsum plaster and joint compound – Scrub with warm water and detergent
to remove any remaining material. Thoroughly rinse off any residue and allow
concrete surface to dry prior to application of any TEC
®
materials.
• Adhesive
• Cutback Adhesive Residue (non-asbestos) – Application over asphalt-based
cutback adhesive residue is acceptable provided the residue is well bonded
and can achieve a minimum of 72 psi (0.5 MPa) tensile bond strength. Scrape
and remove adhesive until all that remains is a thin, transparent layer.
Note: Mechanical removal of cutback by sanding, grinding or blasting can be
hazardous since old cutback adhesive may contain asbestos. Harmful dust may
result. Inhalation of asbestos dust may cause asbestosis or other serious bodily
harm. Consult all applicable government agencies for rules and regulations
concerning the removal of floorings and adhesives that contain asbestos.
• Tacky or pressure-sensitive adhesive – Do not apply TEC
®
underlayments over
these adhesives. They must be mechanically removed by a method such as
shot blasting.
