Substrate preparation:
All flat, load-bearing areas, which can be covered
with tiles are suitable and which are also suitable for
bonded waterproof membranes used beneath tiling.
Furthermore the substrates suitability must be given
for the appropriate wet duty exposure class. Suitable
substrates are e.g. concrete with a dense microstructure,
PII and PIII renders, fully pointed masonry work, cementbased screeds, moisture resistant plasterboard and
gypsum fibre boards. Using a cement mortar, smooth
out large pored substrates such as concrete foundation
blocks, dense concrete blocks and masonry work.
The substrate must be load-bearing, adequately flat,
free from penetrating cracks and free from separating
substances such as e.g. oil, paint, laitance and loose
areas. The substrate must have a largely closed
surface texture and strength appropriate to its type.
Separating cracks must be professionally assessed and
adhesively sealed as necessary beforehand with e.g.
ASODUR-K900.
Renders should have a minimum compressive strength
of 2.5 N/mm² for the installation of tiles and be
suitable for use in the particular wet duty exposure class.
Pre-wet substrates so that at the time AQUAFIN-1K-flex is
applied, they are matt damp. Prime very absorbent and
insignificantly sanded substrates with ASO-Unigrund.
Ensure that there is no height differentiation within the
substrate and that moisture penetration from the rear is
excluded.
Level out irregularities appropriately before applying
AQUAFIN-1K-flex. Levelling can be carried out with
e.g. with the levelling compounds SOLOPLAN-30,
SOLOCRET-15 or SOLOCRET-50.
In wet duty areas form adequate falls towards the
drainage outlets.
Floor drain outlets should have a thin-bed flange with a
minimum 5 cm circumference width and be made from
materials suitable for bonding such as e.g. stainless
steel, red brass or PVC-U.
Heated screeds must be commissioned to recognised
technical regulations in readiness for tiling. The
readiness of a screed to receive finishes is to be
determined by moisture measurements with a carbide
hygrometer. The CM moisture content may not exceed
• CT ≤ 2.0 CM% for screeds on insulation or
separating layers
• CA without underfloor heating ≤ 0.5 CM%
• CA with underfloor heating ≤ 0.3 CM%
Calcium sulphate screeds can be accepted in areas
without planned drainage (floor outlets). They must
be mechanically abraded, vacuumed and as with
all calcium sulphate based substrates primed with
ASO-Unigrund.
Product preparation:
Place approx. 4.6 – 4.8 litres of water into a clean
mixing bucket and stir together with 15 kg powder to
a homogenous, lump free consistency. Using a rotating
mechanical mixer (approx. 500 – 700 rpm) a mix time
of 2–3 minutes is required. Apply AQUAFIN-1K-flex by
spray, brush or trowel techniques in a minimum of two
operations.
The second coat as well as further coats should only
be applied when the first coat will not become
damaged by foot traffic or from further application.
Apply coats up to a maximum of 2 kg/m² in one
operation, as greater thicknesses can result in cracks in
the coating layer. Suitable joint tapes and pre-formed
pieces are named under “Technical data/system
components” in this technical data sheet. Bond the joint
tape or pre-formed pieces with AQUAFIN-1K-flex and
then integrate seamlessly into the waterproof membrane
and completely cover.
1. Prepare the substrate appropriate for its requirements.
2. Pre-wet substrates so that at the time AQUAFIN-1K-flex
is applied, they are matt damp. Prime very absorbent
and insignificantly sanded substrates with
ASO-Unigrund. Allow the priming to dry before
further work.
3. Apply AQUAFIN-1K-FLEX with a steel float, paint
brush or suitable spray equipment. An even thickness
is achieved when a 4 or 6 mm notched trowel is used
followed by smoothing out. Overcoat any missed areas.
At least two coats are required. The previous coat must
be dry before applying the next.
4. To form water impermeable movement and
connecting joints insert the ASO-Joint-Tape system.
Apply AQUAFIN-1K-flex to both sides of the joint to
be bridged, 2 cm wider than the tape with a 4–6 mm
notched trowel. Lay the ASO-Joint-Tape system into the
wet coating and then thoroughly press, without voids
or folds, into the waterproof coating with steel float or
pressure roller. Ensure there is a full bed and contact.
Ensure that the tape is bonded in such a way as to
prevent water from migrating around the back of the
ASO-Joint-Tape system. The tape is laid in a loop into
movement joints. Overlap butt joints by 5 to 10 cm
and fully bond, without folds, with AQUAFIN-1K-flex and
overcoat.
5. The thin-bed installation of the tiles is achieved with
a polymer modified thin-bed adhesive named under
“Technical data/system components” in this technical
data sheet.
Advice:
• P rotect areas not to be treated with AQUAFIN-1K-flex
from its effects.
•A
void dropping below the dew point (condensation
formation) during the drying phase of AQUAFIN-1Kflex.
•A
t high temperatures a slightly sticky surface may be
encountered due to the high polymer content. In this
case we recommend that post treatment is carried out
with water in order to guarantee complete hydration.
• In rooms with low temperatures, higher humidity
and inadequate ventilation, an extended drying
time is to be expected. Forced air heaters are not
recommended for drying in these rooms.
•W
hen there is strong sunlight, work in the shaded
areas against the direction of the sun. Dampen very
dry and porous substrates before application or prime

with ASO-Unigrund as necessary. The substrate may
be matt damp. Avoid the formation of puddles.
During the curing process no water should come
into contact with the waterproof membrane. Water
pressure from the rear can lead to delamination in
frost.
If there is moisture from the rear, pre-coat with
AQUAFIN-1K. Dependent on the severity of
dampness, it may be necessary to apply one or
more coats. Where there is ground moisture the
consumption will be a minimum of 1.75 kg/m² and
where there is standing run-off (seepage) water it
will be a minimum of 3.5 kg/m². Pre-treatment may
also be carried out with INDUFLOOR-IB1240 or
INDUFLOOR-IB1245 dependent on the project.
Eliminate direct contact with metals like copper, zinc
and aluminium by priming until the pores are closed.
Pore-tight priming can be produced by two coats of
INDUFLOOR-IB1225. The first coat is applied to the
substrate, which has been cleaned with universal
cleaner, and carefully worked in by brush. After this
coat has reacted sufficiently so that it can no longer
be disturbed (approx. 3 – 6 hours), brush on a
second coat and broadcast with quartz sand
(0.2 – 0.7 mm grain size). Consumption: approx.
800 – 1000 g/m2 INDUFLOOR-IB1225.
For waterproofing to PVC and stainless steel flanges:
Abrade the flange, degrease with universal cleaner,
apply AQUAFIN-1K-flex and without voids or
folds, bed in the ASO-waterproofing gasket-floor or
alternatively the ADF-pipe gasket. Tie in seamlessly
with the waterproof membrane.
The relevant current regulations are to be observed.
