Durable, cementitious, self -leveling underlayment
iF�ci�r1�CT �•����.� ��'
SikaLevel° Self Leveling Underlayment is a one -
component, durable and versatile cementitious
underlayment for interior concrete, and cementitious

produce a self -smoothing, rapid -setting, flat and
economical substrate prior to the application of a final
floor finish. Typical application thickness is 1/8 to 2
inches* (3 to 50 mm).

Please consult coating manufacturers for recommendations. It is always
important to checkthe moisture content of the floor/slab before applying a
coating. Meeting the specifications of the manufacturer. This can be done
with a moisture meter.

SURFACE PREPARATION
All substrate must be dry, stable, sound and free of all
contaminants such as grease, oil, paint, wax, dust, curing
and sealing compounds that will interfere with the
penetration the primer and the adhesion of SikaLevel®.
Careful consideration should be given to the selection of
the method of mechanical surface preparation and the
timing of application of primer and underlayment.
Immediately following mechanical preparation on some
excessively porous substrates, outgassing will increase
for a short period of time (approx. 48 hours) until
equilibrium in slab vapor pressure and the ambient
environment is reached. Consult Sika Technical Service
for recommendations.
Concrete & Cement Substrates: Prepare concrete,
cement and dense substrates, including ceramic, quarry
and vinyl tiles by mechanical means, such as shot
blasting, sandblasting, water jetting, scarifying, or other
appropriate methods, to achieve an open -textured, fine -
gripping surface (ICRI - CSP 3 minimum). Weak surfaces
should be removed. All cracks and holes should be
similarly filled to prevent seepage. Repair with Sika®
Level Skim Coat prior to priming and levelling. The
compressive strength of the concrete substrate should
be at least 2,900 psi (20 MPa) at 28 days with a
minimum tensile strength of 200 psi (1.4 MPa).
Cutback Adhesive: Old water-soluble adhesives should
be removed completely. Old water-resistant adhesives
should be mechanically removed as far as possible. The
complete mechanical removal of cutback (i.e. grinding,
sanding and blasting) can be hazardous as old cutback
adhesive may contain asbestos. Do not sand or grind
adhesive residue. Harmful dust may result. Inhalation of
asbestos dust may cause asbestosis or other serious
bodily harm. Please consult the adhesive manufacturer
and all applicable government agencies for rules and
regulations concerning the removal of flooring and
adhesives that contain asbestos.
Priming
Prime standard absorbent substrates such as concrete
and cement with SikaLevel° Primer.
This product is not a vapor barrier and will allow free
passage of moisture. Follow the directions of the floor
covering manufacturer regarding the maximum
allowable substrate moisture content and test the
substrate prior to installing SikaLevel®.

MIXING
Pour 1 gallon (4 quarts) of cool potable water (70 °F)
into a suitably sized and clean mixing container, using a
calibrated measuring jug, or similar, to ensure strict
control of the water content (do not over -watering). If
available water is not at this temperature, then
consideration should be given to cooling/heating the
water. Add SikaLevel° to the water, while slowly stirring,
adding the complete contents of the 50 lb. bags.
Mix with a high-speed drill (more than 650 rpm) and an
egg beater style mixing paddle to blend water and
powder for approximately 3 minutes, until a lump -free
and uniform mix has been produced. Do not overmix or
allow the paddle to rise above the level of material as
this will introduce and entrap air into the mix,
potentially shortening the working life or causing pin -
holing in the underlayment. Let the mixed material
stand until the majority of air bubbles have dispersed.
APPLICATIOW
Pour the mix and spread using a smoothing trowel. Even
surfaces are easily achieved using a pin leveler. In higher
thickness using a spike roller is recommended. Avoid
contact to vertical structures by putting in an edge strip
such as foam tape.
If a second layer of leveling compound has to be applied,
prime the first layer with Sika® Level Primer when the
first layer is walkable. The maximum layer thickness
must not be exceeded in case of two layer applications.
The second layer must not exceed the layer thickness of
the first layer.
Protect curing SikaLevel° layers from high ambient
temperatures, direct sunlight and ensure an adequate
air circulation.
The cured surface of SikaLevel° must be protected from
any type of contamination by installing a suitable
coating. Always install an adequate number of properly
located test areas, to include the finish flooring, to
determine the suitability of the product for its intended
use. As floor coverings vary, always contact and rely
upon the floor covering manufacturer for specific
directions such as maximum allowable moisture
content, adhesive selection, and intended end use of the
product. Low substrate temperatures and/or high
ambient humidity require longer drying times for
primers. SikaLevel® is not intended to be use as a wear
layer.
All cement based products have the potential for

cracking. Cracking, such as hair line cracking cannot be
considered as a product defect or installation failure.
For large scale areas that require deeper applications,
the following recommendations can be used to minimize
material cost:
1. The material can be extended by adding up to 30 % of
20/30 grade sand during mixing to achieve up to 2" in
one lift. A reduction in flow, approximately 15 %, can be
expected. The final layer should be neat to allow for a
smooth finished floor. When adding aggregate, expect
coverage to increase by approximately. 16 cu.ft. per 25
Ibs of aggregate.
2. Pre -washed 3/8 pea -gravel can be pre -placed into
the area being leveled allowing for up to 2" in one lift.
Applicator must be aware that the aggregate can cause
voids in the underlayment if not filled correctly. When
adding aggregate, expect coverage to increase by
approximately .16 cu.ft. per 25 Ibs of aggregate. Multiple
lifts can also be applied to achieve greater depths,
making sure to prime with Sika® Level Primer in between
lifts. If necessary, further detailed recommendations can
be obtained by calling Sika Corporation's Technical
Service Department. Over large areas, application by
conventional piston, rotor -stator or underlayment type
pumps is more appropriate. Thoroughly spike roll in two
directions (90 °) to remove installation marks and any
entrapped air, but avoid overworking.
CLEANING OF TOOLS
Clean tools in water immediately.
Disposal:
Empty packaging and dispose of in accordance with
federal, state and local waste disposal regulations.
LIMITATIONS
For interior use only. Not suitable for slopes or inclines
> 0.5 %
Do not apply SikaLevel" onto based, chipboard,
particle board, hardboard, metal, gypsumbased floors
or dimensionally unstable substrates.
Always prime concrete and cement substrates with
Sika" Level Primer.

byturning off radiant heating and forced air ventilation
for 24 hours before installation and while the
underlayment is curing.
o Do not exceed the recommended water dosage and
use clean potable water.
o Temperature variations will affect working time, with
low temperatures extending drying times.
o Protect newly applied SikaLevel" from condensation
and water for at least 24 hours.
• Prevent contaminants, dust and dirt from coming into
contact with the underlayment for at least 4 hours and
do not expose to rolling dynamic loads for 2 days (at 73
7, 50 % R. H.).
o If subsequent layers of SikaLevel® are installed on
existing, cured SikaLevel°, mechanical preparation and
re -priming is required.
o As the thickness of the underlayment will influence the
time at which it can be overcoated or overlayed with
stones, tiles, or coverings, the manufacturer of such
materials must be consulted for guidance regarding
substrate moisture content and other characteristics.
o SikaLevel° does not provide an aesthetic finish and is
intended to receive a final floor covering.
• For adhesives other than SikaBond", we recommend a
test application prior to use.
o All cement based products have the potential for
cracking. Cracking, such as hair line cracking cannot be
considered as a product defect or installation failure.
Results may differ based upon statistical variations
depending upon mixing methods and equipment,
temperature, application methods, test methods, actual
site conditions and curing conditions.
