at 7 days
approx. 21 N/mm2
at 14 days
approx. 25 N/mm2
at 28 days
Flexural strength: 6.2 N/mm2 at 28 days
(ASTM C 580:96)
Adhesion strength: 1.0 N/mm2
(ASTM D 4541:2002)
Water impermeability: > 13 bar negative or
positive side
Surface preparation:
The substrate must be sound, clean and have an open
capillary structure. The surface must be porous and
permit a good surface adhesion so that the chemicals
can penetrate well into the concrete. Horizontal areas
should have a rough surface. Smooth surfaces must be
mechanically abraded in order to achieve good
penetration.
1. All adhesion inhibiting substances such as dirt,
cement laitance, mould oil, hardeners, loose
components, paint etc. must be removed by
sand blasting, water jetting or other mechanical
methods.
2. Eradicate all ridges, gravel pockets and other
damaged areas. Poor joints and visible cracks
(non-dynamic) above 0.4 mm should be chased out
20 mm wide by 25 mm deep. Anchoring holes
should be roughened.

3. Plug water leaks with FIX 10-S plugging cement.
4. Repair damaged areas with the repair mortar
ASOCRET-RN or ASOCRET-IM dependent on area
of application.
5. Pre-treat all connecting joints and construction joints
with ASO-Joint-Tape-2000-S and AQUAFIN-2K/M
(please see Technical Data Sheet).
6. Thoroughly pre-wetting all surfaces before
application of AQUAFIN-IC with clean water.
Repeated dampening may be necessary to ensure
complete saturation, which promotes deeper
penetrating crystalline growth. The substrate should
be matt damp, without puddles or standing water.
Product preparation:
Pour 6.75 to 8.0 litres of clean water into a clean
mixing bucket and mix in sufficient dry mortar while
mechanically stirring (drill at 300 – 700 rpm) until a
lump free, homogenous fluid or sprayable consistency
is achieved. Only mix as much material as can be
used within the pot life. After a maturing time of min.
3 minutes, stir again.
Application:
Dry shake application:
Concretes must be designed to develop a good load
bearing capacity. AQUAFIN-IC must be broadcast at
the coverage rate appropriate for the expected water
exposure (see under “Estimating & Supply”) on to freshly
poured concrete.
For large areas it is recommended that the floor be
marked into bays with known area. Sufficient
AQUAFIN-IC should then be laid out to meet the
recommended spread rate. Once the concrete has
started initial setting (light foot traffic imprint of 3-5 mm)
apply AQUAFIN-IC immediately. When AQUAFIN-IC
absorbs the concrete moisture entirely and a uniform
darkening of colour takes place, commence with the
power floating. Do not overwork the material.
Application by brush:
Spread two coats of AQUAFIN-IC at the required
quantity in a slurry consistency with a roofers brush or
builders brush. Brush thoroughly and evenly, working
into the substrate. Apply the second coat whilst the first
coat is still tacky and hasn’t dried out.
Spray application:
AQUAFIN-IC can be applied with the aid of suitable
compressed air spray equipment. Dependent of the final
wet duty of the installation spray apply one or two coats
in a circular motion. Apply the second coat whilst the
first coat is still tacky and hasn’t dried out.
Curing and protection:
a) In exteriors or exposed areas: keep AQUAFIN-IC
damp for min. 3 days. Protect areas exposed to the
weather from sun, wind and frost with e.g. polythene
sheets, canvas etc. Re-wet the area in intervals with
water, starting 1 day after application. Alternatively
the surface can be covered with polythene. The fresh
coating should be protected from rain for a minimum
of 24 hours. Backfilling can take place 3 days after
the last coat.
b) Interiors: In areas with high humidity the material
cures very well. In relatively dry areas keep the
coating damp for 3 days. Ensure that there is
adequate ventilation for 24 hours in areas of poor
ventilation and deep pits.
c) Containers and tanks: Filling is possible after 3 days.
In the case of drinking water storage, the container
must be thoroughly rinsed with drinking water before
filling. When properly installed, AQUAFIN-IC is
permanently active.

Important advice:
• Protect areas not to be treated with AQUAFIN-IC from
its’ effects.
• AQUAFIN-IC cannot be used as an additive for
concrete or renders.
• With concrete containing fly-ash it is possible that
successive coats of AQUAFIN-IC may discolour and
there may be an impaired reaction. The fly-ash
component according to ASTM C-618 type C may
only be max. 30% of the binder. The minimum
quantity of CaO in the fly-ash should not be below
15%. Please contact the technical department
regarding particular specification for concretes with
type C fly-ash with low CaO content, type F or other
pozzolanic concrete additives.
• The reaction between AQUAFIN-IC and free lime in
concrete can lead to minor efflorescence. This is not
detrimental and can be removed with a brush.
• Different colourings are dependent on the differing
dampness of the concrete.
• Temperatures around +10° C to +15° C are to be
expected in water containers. In order to guarantee
complete hydration of the cement, keep the coating
damp for an adequate length of time (constant relative
humidity of > 80%) and protect against drying out. In
general 7 days is sufficient. It is essential to avoid the
formation of condensation or standing films of water
during this time period. Where there is a danger of
dropping below the dew point (condensation
formation) install dehumidifiers until the mortar is
cured. At no time should uncontrolled warm air be
blown inside.
• To increase pot life/working time at higher
temperature store material in a cool environment
above +5° C and only expose to warm temperature
shortly before mixing. Additionally use of cold water
can also increase pot life/working time, if water
addition is necessary.
• AQUAFIN-IC may need up to one month to achieve
its maximum waterproofing properties. Influencing
factors are ambient temperature, humidity, concrete
composition etc.
