Concrete Leveler
™
Contractors and Engineers choose Concrete
Leveler for self-leveling oor underlayment
applications when a fast, durable and
economical solution is required.
DESCRIPTION
Concrete Leveler is an advanced hydraulic
cement-based self-leveling underlayment that
can be used both indoors and outdoors. Con-
crete Leveler rapidly levels, maintains work-
ability for 30 minutes and produces a at,
strong surface with high bond strength. Con-
crete Leveler is designed for fast-track level-
ing applications and can be covered with nished
ooring in 4 to 16 hours at 70˚F (21˚C), depending
on the ooring type. This advanced underlayment
can be applied from featheredge to 1˝ (25 cm)
thick and up to 5˝ (127 cm) thick when extended
with aggregate.
APPLICATIONS
Use Concrete Leveler when a high quality, fast-
setting, self-leveling underlayment is needed.
Concrete Leveler is ideal for all oor projects
that need long ow life and working time while
achieving high 24-hour strength. Concrete
Leveler is an excellent choice for new oor
projects and repair projects.
ENVIRONMENTAL ADVANTAGES
Use Concrete Leveler to reduce your carbon
footprint and lower your environmental impact.
Production of Rapid Set cement emits far less
CO
2
than Portland cement. Contact your Rapid
Set representative for LEED values and more
environmental information.
SURFACE PREPARATION
Concrete substrates must be clean, sound, and free
of oil, curing compound, dust, mastic, bond breaker
and any other material that prevents good bonding.
Concrete should be free of hydrostatic pressure,
and vapor emission rates should comply with the
nished ooring manufacturer’s requirements.
Smooth concrete and hard troweled surfaces should
be prepared to achieve a surface prole similar

Datasheet
to ICRI CSP 3. Mechanical methods of surface
preparation such as shot blasting are preferred.
Acid etching the substrate is not recommended.
Surface must be dry, have a minimum temperature
of 50˚F (10˚C), and be properly primed. Honor all
moving joints and cracks.
PRIMING
Apply Rapid Set
®
Concrete Leveler
™
Primer to
all substrate surfaces prior to placement. Follow
the application instructions stated on the primer
product packaging.
MIXING
Add one 50-lb (23-kg) bag of Concrete Leveler to
4.5-5 quarts (4.2-4.7 L) of potable water. Do not
exceed 5 quarts (4.7 L) of water. Concrete Leveler
may be mixed using a drill-mounted paddle mixer,
or by using an appropriate mixer and pump. Mix
3-5 minutes until the mixture is smooth and lump
free. Avoid mixers that entrap large amounts of
air. Mixed Concrete Leveler should be used within
30 minutes at 70˚F (21˚C). Maintain material
temperature above 50˚F (10˚C).
PLACEMENT
Prior to placement, conrm that the primer is
completely dry. Pour or pump Concrete Leveler
onto the substrate up to a maximum thickness
of 1˝ (25 cm). Use a gauge rake, spreader or
other tools to place the material. Use a spiked
roller to remove any entrapped air if necessary.
A smoother trowel may be used to smooth the
material. Concrete Leveler can be troweled to a
featheredge to match existing elevations.
