3. DESCRIPTION
EZ Level
®
Premium Self Leveling Underlayment is a cement-based, pourable,
pumpable and free flowing underlayment. It is designed for smoothing and
leveling most subfloors and is particularly well-suited for large areas. The
resulting smooth finish is ideal for the installation of all types of floor covering,
including ceramic or natural stone tile, carpet, 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 EZ Level
®
. Create a minimum of
1
⁄8 " to
1
⁄4 " (3-6 mm) wide
gaps where self-leveling underlayment abuts walls, columns, and fixtures
by installing a self-sticking sponge rubber weather stripping or damp sand
(Vacuum up sand after self leveling underlayment has cured.)

)
per 24 hours, RH 95% or lower]
• Fast setting—dries to walkable surface in 2 to 4 hours, with flooring installation
in 12 to 16 hours
• Contributes to LEED
®
project points

Suitable Substrates
When properly prepared, suitable substrates include:
• Concrete • Ceramic, porcelain, or quarry tile
• Pavers • Cement or epoxy terrazzo
• Cement backerboard • Exterior grade plywood
• Oriented Strand Board (OSB)
• VCT or full glued down, non-cushioned vinyl sheet goods
• 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
EZ Level
®
. 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: EZ Level
®
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 EZ Level
®
.
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 EZ Level
®
(see The LiquiDAM
®
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.
