Product Description
DESCRIPTION
Sika MonoTop-122 F trowelable mor tar is a dual
shrinkage compensated, thixotropic high strength formulation
for structural concrete repairs. Sika Mono-
Top-122 F is suitable for placing in thicknesses of
5mm to 50 mm vertically and 5-15mm overhead.
USES
Repair of spalling and damaged concrete in buildings,
bridges, infrastructure and super structure works
CHARACTERISTICS / ADVANTAGES
Easy to use (only to be mixed with water)
Structural an Cosmetic repairs
Possible to apply on vertical substrate in 50mm layers.
Good adhesion strength
Ideal where the repairs are more than 5 mm
Sprayable - able to repair complex profiles easily
with minimal rebound

APPLICATION INSTRUCTIONS
SUBSTRATE QUALITY / PRE-TREATMENT
Substrate Quality :
Concrete:
The concrete shall be free from dust, loose or friable
material, surface contamination or other materials
which reduce bond or prevent suction or wetting by
repair materials.
Steel Reinforcement:
Rust, mild scale, mo rtar and concrete residues, dust
and other loose or friable material and other contamination
which reduces bond shall be removed.
Pre- Treatment :
Concrete:
Delaminated, weak, damaged and deteriorated concrete
and where necessary sound concrete shall be removed
by suitable mechanical or very high pressure
water-blasting techniques (up to 110 MPa).
Tie wire fragments, nails and other metal debris embedded
in the concrete should be removed.
The edges around areas of concrete removal should
be angle cut at a minimum of 90o to avoid undercutting
and a maximum angle of 135o (with the top surface
of the adjacent sound concrete), to reduce the
possibility of de-bonding. They should then be
roughened sufficiently to provide a mechanical key
between the original material and Sika MonoTop-122
F repair mor tar.
Bonding primer:
On a well prepared and roughened substrate a bonding
primer is generally not required. When a bonding
primer is not required pre-dampen the surface to a
saturated surface dry condtion. The surface should not
be allowed to dry before application of the concrete
repair . The surface should have a darkened
matt appearance without glistening and the surface
should not have free-standing water.
When a bonding primer is necessary, apply Sika Latex
/ Sikadur 32 LP / Sika Hibond- (Refer to the relevant
Product Data Sheet).Pressed well on to the substrate.
In all cases, subsequent application of the repair mo rtar
should be done wet on wet.
Measured pull off values - Structural Repairs minimum
value 1.2 - 1.5 MPa; Non Structural repairs minimum
value 0.7 MPa (Dependent on the strength of the
concrete being repaired).
MIXING
Mix powder mechanically in the correct ratio with water
with low speed (max. 500 rpm) electric drill to
avoid entraining too much air. In case of 2 or more
bags at once use forced action mixer.
Put around 80 to 90% of required water in the mixing
drum, followed by Sika MonoTop 122 F and then add
the balance water.
Dont use concrete tilting mixer.
Do not mix more material which cannot be used within
Pot Life. DO NOT ADD EXTRA WATER.
Mix for atleast 3 minutes.
APPLICATION
Apply Sika MonoTop-122 F manually using traditional
techniques
When a bonding primer is used, ensure it is still tacky
when the repair material is pressed on (wet on wet
technique). When applied manually, press the repair
mor tar firmly with a trowel, pushing it well on to the
substrate.
Smoothening with trowel or finishing by Float or
sponge can be done as soon as mor tar has started to
stiffen.
CLEANING OF TOOLS
Clean all tools and application equipment with water
immediately after use. Hardened material can only be
removed mechanically.
FURTHER DOCUMENTS
Avoid application in direct sun and/or strong winds.
Do not add water over recommended dosage.
Do not add additional water during the surface finishing
as this will cause discoloration and cracking.
Cure freshly applied material correctly and protect
from freezing etc.
