APPLICATION INSTRUCTIONS
SUBSTRATE PREPARATION
• Substrate must be clean, dry, sound and
homogeneous, free from oils, grease, dust and loose
or friable particles. Paint, laitance, and other poorly
adhering contents must be mechanically removed.
• Substrate must have an open textured surface to allow
Sika® MB to penetrate. (i.e. Blast cleaning, grinding are
considered acceptable means to achevie the desired
surface profile. Acid and chemical etching are not
acceptable).
• At least 50 %of the surface area must be cleared of
residual adhesive and cutbacks. (i.e. by grinding or
mechanical substrate preparation)
• Old cutback can contain asbestos which is dangerous
for the health so do not grind, sand or blast. Refer to
the Resilient Floor Covering Institute's publication
"recommended work practice for removal of resilient
floor coverings" for instruction.
• Minimum substrate compressive strength > 1,160 psi.
Tensile Bond strength > 116 psi at the time Sika® MB is
applied.
• Repair with Sika' Level SkimCoat or SikaQuick' mortar
before priming.
• The floor must be cleaned with an industrial vacuum
prior to installation of the Sika® MB.
• On fiber reinforced concrete, fibers should be flamed
off the surface prior to application of Sika® MB as a
moisture barrier.
• Before overall installation begins, Sika' recommends
the application of several small test patches to
determine primer application requirements and
acceptability of final product performance.
MIXING
• Add one full can of component A to one full can of
component B then mix with an electric drill and mixing
(Jiffy Mixer type) paddle at a low speed to reduce air
entrainment (300-400 rpm). Using a paint stick or
similar is not sufficient to mix the primer.
• A minimum mixing time of 3 minutes shall be
observed; mixing shall continue until a homogeneous
mix has been achieved.
• Scrape sides of pail with paint stick or paddle to ensure
all contents are thoroughly mixed together.
• Unmixed material applied to the floor will not cure
properly.
APPLICATION METHOD/TOOLS
• Apply Sika® MB uniformly (in 2 directions 90•) to the
substrate using a medium nap roller, ensuring that a
continuous coat is achieved over the entire surface
(MUST produce a mirror like finish).
• Pour contents of pail onto the floor for best working
time. Attempting to work from the pail will reduce
working time.
• When used as a moisture barrier and substrate
consolidation / adhesion promotor, prepare the

substrate mechanically as in accordance with the
guidelines stated in subtitle "Surface Preparation".
Apply the first coat at 30 mils Apply the second coat at
15 mils in accordance with the open time*.
2 coats application: Apply the first coat at 75-115 ftl/gal
Apply the second coat at 150-225 ft2/gal in accordance
with the application time window*. Then follow one of
the option:
• Option 1: Broadcast to refusal with oven dried silica
sand (20/30) on the second coat immediately. Sweep
sand once the epoxy is cured. Apply Sika® Level
products on cured epoxy.
• O to ion 2: Apply Sika® Level-02 EZ Primer in accordance
with the application time window*. When the primer is
dry, apply Sika® Level products.
-ref. to appliction time in sections above
CLEANING OF TOOLS
• Clean all tools and application equipment with cleaning
solvent (Xylene, MEK are effective).
• Hardened/cured material can only be removed
mechanically.
LIMITATIONS
• Proper coverage must be used to achieve moisture
barrier properties.
• Will not act as a moisture barrier for gypsum screeds.
Gypsum based subfloors are very susceptible to excess
moisture and will be degraded if exposed to excess
moisture from below or above.
• Only protects from moisture coming from below the
concrete.
• Will not prevent hydrostatic pressure.
• Must not be applied to a visibly wet substrate.
• Does not prevent moisture occurring between the
epoxy and the floating floor due to secondary sources
of moisture or acclimation, e.g. water condensation.
• Is not suitable for use with bonded systems due to
possible curing and adhesion problems.
• Sika' recommends the use of Sika" Level products on
top of it.
• Floor covering manufacturer's and Wood flooring
manufacturer's recommendations, like room humidity
levels and wood acclimation requirements should be
strictly followed.
• Sika' does not make any standing recommendations as
to the structural integrity of old adhesive residues or
subflooring materials that are not manufactured by
Sika'.
• When left on the substrate for more than the
maximum allowable open time of 36 hours, prior to
placing the adhesive, the surface must be thoroughly
cleaned and mechanically prepared (i.e. screened
sand) and solvent wiped. Failure to do this, may result
in adhesion problems. For detailed instruction contact
our Technical Service. When used in conjunction with
Sika Bond', Sika° MB does not need to be broadcasted
With sand.
