8 | System structure/system description
An external wall insulation system can only be applied
if the substrate satisfies certain criteria and is tested for
its load-bearing capacity. In the case of soiled, absorbent
or uneven substrates, pre-treatment is always necessary;
in the case of non-load bearing substrates, the system
must be applied with a mechanical fixing system.
Primers are always applied diluted to suit the substrate.
Primers must not remain glossy after drying.
After successful substrate preparation, the next important
step is to choose the right adhesive for the selected system.
Depending on the system and the substrate, additional
dowelling of the insulation boards may be required.
During mechanical fixing (rail fixing or fixing with Sto-Rotofix
plus), substrate preparation can be eliminated, although it is
essential in this case to ensure that the masonry is dry.

Bonding
Insulant
Sto-Polystyrene Rigid Foam Boards are
delivered cut to precise angles, with
straight edges and dimensionally accurate
and are available with straight or overlapped edges and as a groove and tongue
construction set.
Load-bearing substrate, suitable for
bonding, with an unevenness of up
to 1 cm/m
In the case of load-bearing substrates
suitable for bonding (≥ 0.08 N/mm2), it is
sufficient to bond the insulation board
with a minimum bonded proportion of
40%.
Important
Bonding and dowelling
Substrate suitable for bonding with
insufficient load-bearing capacity
and/or an unevenness of up to
2 cm/m
In the case of substrates with an insufficient load-bearing capacity (< 0.08 N/
mm2), additional dowelling with approved
dowels is required.
Mechanical fixing
M system (centre image):
an unevenness of up to 3 cm/m and/or
substrates not suitable for bonding
Sto-Rotofix plus:
an unevenness of up to 7 cm/m and/or
substrates not suitable for bonding
In the case of substrates with an unevenness between 2 and 7 cm/m, a mechanical
fixing system must be used. Alternatively,
the substrate may be replaced or steined
or the render and/or paint coat may be
removed by mechanical means.
The mechanical fixing systems are also
used for substrates with an insufficient
load-bearing capacity (< 0.08 N/mm²).
10 | Fixing systems/insulation board fixing (EPS)
Protect the polystyrene rigid foam boards against the action of heat,
UV radiation, moisture and mechanical damage (do not use moist,
wet or damaged insulation boards). Due to the silver/grey colour
shade of the insulation board (thermal conductivity group 032),
measures for preventing thermal heating should be considered. The
insulant should therefore be protected against direct solar radiation,
e.g. by means of scaffold netting, during and after application.
Further coatings should be applied within a few days.
Bonding the insulation boards
Excessive drying times of the bonding mortar on the insulation
board or wall lead to the formation of a skin on the bonding
mortar which can lead to adhesion problems. Immediately
after application of the bonding mortar (after 10 minutes at
the latest), press the insulation boards onto the adhesive,
have them float into place and press-fit them. Depending on
the weathering, this time interval may be shorter.
Install the insulation boards from bottom to top, in an offset
pattern and so that they abut, leaving no open joints between
the insulation boards. Unavoidable joints must be sealed with
a suitable filler foam.
Use insulant strips to seal joints with a width greater than
5 mm.
There must be no base coat mortar in joints or between board
joints. Damaged insulation boards must not be installed.
Scatter offcuts (minimum width 15 cm) across the surface
(not at the outer edges of a building or building apertures).
Seal the gap between the starter track and the wall using a
suitable filler foam.
Important
Sto-Starter Profiles
After establishing the height of the plinth, the Sto-Starter Profiles are
mounted torsion-free, vertically and flush (see application details).
Seal the gap between the Sto-Starter Profiles and the wall using a
suitable filler foam.
Bonding
Tip
2b
Preventing thermal bridges: Thoroughly remove bonding mortar
between board joints or joints immediately.
1a
Full-surface bonding
In the case of smooth substrates, apply the
bonding mortar to the entire surface of
the insulation board and tooth with a
toothed trowel (15 x 15 mm). When
doing so, do not hold the toothed trowel
too flat. Use an emery board for board
fixation.
2a
3b
After pressing the board onto the
adhesive, the bonded proportion must
be at least 40% on both the substrate
and the insulation board.
1c
Machine application of bonding
mortar to the insulation board
In the case of even and uneven substrates
up to 1 cm/m, apply an all-round line of
adhesive with an enclosed W or M.
3a
After pressing the board onto the bonding
mortar, it is important to ensure that the
board adheres evenly to the substrate.
2c

Spot/edge bonding
In the case of uneven substrates up to 1
cm/m, apply a line of adhesive all around
the edge of the boarding and 6 adhesive
fixing dabs on the surface.

mortar to the wall
In the case of smooth substrates, apply an
adhesive bead in sinuous lines with a
max. spacing of 10 cm to the wall.
Substrate:
In the case of substrates with an insufficient load-bearing capacity,
the insulation boards must be dowelled as well as bonded.
Please note: Only use dowels with the appropriate approval!
Depending on wind loads, building height, location, etc.,
additional dowelling may also be necessary for load-bearing
substrates. The relevant European and/or national specifications
must be observed.
Anchorage depth:
The dowel must be anchored in the load-bearing substrate at
the depth required by the relevant dowel approval. Tiles and
old render are not classed as suitable anchorage substrates.
2d
Pull-out tests:
In the case of undefined substrates, the pull-out strength
must be determined by taking measurements on the object.
3d
Dowel specifications:
The dowel length depends on the existing wall structure and
the insulant thickness. The number of dowels depends on the
height and location (surface, edge). Dowelling is usually
located beneath the reinforcing coat or the reinforcing mesh.
Ensure an even dowelling pattern.

Laying of the insulation boards
Lay insulation boards from bottom to top,
tight-butted in a bond and offset to the
building corners. Press the boards firmly
onto the wall. Remove any excess adhesive in order to prevent thermal bridges.
In the case of bonding with Sto-Turbofix,
the laid insulation boards must again be
pressed onto the wall and re-adjusted
after max. 10 minutes using a long spirit
level.

Two-layer installation
Tip
If mechanical fixing is required (by a
standard), shorter and therefore
cheaper dowels can be used for twolayer bonding. This eliminates local
thermal bridges and the risk of marks
being left by the dowels.

It is generally recommended that you
force-fit the corner toothing using a

3
Cut off any excess adhesive.
In the case of the insulant thicknesses (> 20 cm) used in low-energy
construction and passive houses, for example, two-layer installation of the
insulation boards is recommended. The second layer of insulant is to be
applied sufficiently offset against the first layer both vertically and in terms
of the joints (no continuous joints).

The installation of two-layer insulation boards allows details to be produced
more easily and free of thermal bridges (e.g. in the case of window
connections).
Important
When installing the second insulation layer, the floating-buttering
method is recommended due to the low absorption capacity of the
substrate (EPS).

system. This is particularly useful if substrate preparation is especially
complex (e.g. if the old render has to be knocked off).
• With StoTherm Classic® and StoTherm Vario, the Sto-Polystyrene
Rigid Foam Boards, M system type, must be used. Additionally, the
PVC tracks must be used for fixing.
• With StoTherm Mineral, the Sto-Mineral Fibre Board 040, M system
type, must be used. Additionally, the aluminium tracks must be
used for fixing.

Using the driving tool, drill a hole approx.
10 cm in depth. Pull out the screwdriver
in slightly circular movements.
5
Screw in the dowel screw using the
driving tool until it sits firmly in place.
When tightening the screw, the
Sto-Rotofix plus must be reset.
2
Screw in the screw coil using the driving
tool. The screw coil must always be
screwed in at a 90° angle to the insulation
board.
6
Using the setting and adjustment tool,
align the insulation board precisely.
Spacing from the wall:
Sto-Rotofix plus green (E1/B3) = max. 3 cm
Sto-Rotofix plus black (E100/B300) =
3 to 7 cm
3
Use a stop drill bit to drill a hole right
through the screw coil. With a rotating
drill, ventilate the drill hole several times.
Do not use the hammer action on a drill
when drilling holes in perforated bricks.
7
Screw the expanded polystyrene rod into
the drill hole and cut off flush with a
sharp blade. Alternatively, the drill hole
can be filled with foam insulation. In case
of mineral fibre boards, seal the drill hole
using mineral fibre remnants.
4
Use the setting and adjustment tool to
press the dowel with the pre-assembled
screw through the screw coil until the
tool makes contact with the screw coil
(checking the setting depth).
8
Grind the surface until it is even.
Notes
• EPS insulation boards must always be fixed with the Sto-Rotofix plus
with the tongue facing upwards and in the direction of laying.
• No boards shorter than 50 cm may be used at building corners.
• Window lintel boards must have a minimum width and a minimum
height of 30 cm.

Base coat
Preliminary works before base
coat application in the case of EPS
insulation boards
Note
Notes
Prior to reinforcement, it is important to check carefully whether the
insulation boards are tight-butted and honed even. A smooth insulant
surface free of open joints prevents, amongst other things, cracks as
well as joint marks on the top coat.
• Due to the extraordinary elasticity of the StoLevell Classic base coat
used with StoTherm Classic®, diagonal reinforcement is not required.
The lightness value of the top coat, however, must be ≥ 20%.
• The window or door connection, which is resistant to driving rain,
must be produced using Sto-Seal Beads and/or Sto-Joint Waterproofing Tape. When using Sto-Seal Beads, the mesh of the seal
beads must first be embedded at the internal reveal sides in the
base coat. See the “Window connection” section on page 37
onwards.
1
Unavoidable joints between the insulation
boards must be sealed with Sto-Pistol
Foam SE. After the filler foam has dried,
smoothly cut off protruding foam.
Use insulant strips to seal joints with a
width greater than 5 mm.
1
At the corners of window and door
openings, diagonal reinforcement must
be installed and embedded in the base
coat before the base coat is applied. The
dimensions are approx. 20 x 40 cm. The
longitudinal edge must be set precisely to
the corner point of the opening.
Note: Under the conditions listed above,
diagonal reinforcement is not required
with the StoTherm Classic® system.
Product tip
2
The internal reveal corners are reinforced
with Sto-Glass Fibre Mesh. The mesh
flanges must be at least 10 cm long.
3
Produce the external reveal corners using
the Sto-Mesh Angle Bead Standard. Cut
the mesh angle bead to size as appropriate,
position it and embed it full-surface into
the base coat. The mesh angle bead must
overlap the internal corners of the mesh
by at least 10 cm.
4
Embed the Sto-Glass Fibre Mesh into
the base coat across the entire wall
(overlapping the opening).
Sto-Filler Foam Pistol Profi I
With the Sto-Filler Foam Pistol Profi I,
the special taper allows the application
of reducing needles that enable cavities
or cracks as small as < 1 mm to be filled.
2
Grind the insulation boards until smooth.
The sanding dust must be removed from
the facade.
Base coat | 21

5
Cut off the mesh at an angle of 45° along
the reveal edge. When cutting to size, the
corners in particular must be clean and
precise.
Important: Before applying the base coat,
check all edges for mesh projections and
cut them off if necessary.
6
Notes
• The specified drying times after bonding the insulation boards must
be observed.
• Sufficient weather protection must be provided during the application
and drying time of the base coat.
Work the mesh into the base coat again
around the area of the cutting edges.
1
Apply the base coat using the square
trowel or by machine at a width of 110
to 120 cm across the entire surface.
Product tip
2
Embed the mesh into the still moist base
coat. The mesh strips must overlap by 10
cm. Then smooth the base coat using a
wide trowel.
Sto-Lintel Corner Mesh Angle
The use of the Sto-Lintel Corner Mesh
Angle for internal corner and reveal
formation lowers labour costs as internal
reveal corners do not need to be
reinforced.
Product tip
Sto-Glass Fibre Mesh
The Sto-Glass Fibre Mesh is flexible
and easy to apply. The mesh format,
with a width of 1.10 m (in the case of
horizontal mesh embedding), covers
exactly one scaffolding platform with
two mesh strips.
Alternative: Sto-Shield Mesh AES for
protection against electro-smog.

Render textures
Notes
• If a rilled render texture is not desired, the intermediate coating can
be omitted when using StoTherm Classic®.
• Sufficient weather protection must be provided during the
application and drying time of the intermediate coating and/or
finishing render.
• The finishing renders can be tinted in up to 800 colour shades of the
StoColor System.
Stippled render texture (K)
A stippled render is applied based on the
grain size and textured with a suitable
tool.
1
After the base coat has dried through,
apply the pigmented priming paint coat
(Sto-Primer or StoPrep Miral) to the entire
surface of the reinforcement using a
roller.
Rilled render texture (R)
Rilled renders can be textured in different
ways following application (horizontal,
vertical and round).
2
After the intermediate coating/base coat
has dried through, the finishing render is
applied wet in wet. The surfaces must be
seamlessly coated.
Free-style textured render (MP)
Fine-grained renders are applied and
textured using a paint brush, spatula,
mason’s trowel, sponge, etc..

Lightness value
In the case of external wall insulation
systems, there are limit values for the
lightness value of the top coat.
The following limit values apply:
•StoTherm Classic®: ≥ 15%
•StoTherm Vario:
≥ 20%
•StoTherm Mineral: ≥ 20%
The lightness value is based on the
percentaged quantity of light reflected
by a surface (100% = white, 0% = black).

StoDeco Profiles
StoDeco Rustications
1
StoDeco Profiles are easy to cut to size
using the StoDeco Profile Hacksaw.
Remove dust from the full surfaces of all
cutting edges using a hand brush (and
compressed air, if available).
2
Comb the StoDeco Coll onto the substrate
and profile with the toothed trowel
(6 x 6 mm) using the floating-buttering
method. Adjust the toothing based on the
unevenness of the substrate. The profile
joints must also be bonded together
across the full surface as described. The
adhesive seam should be approx. 3 mm
thick.
Hold in place with lintel nails during initial
drying. Remove any excess adhesive after
initial drying.
3
Using a round jointer, form the material
oozing out from below into a fillet. This
prevents water from penetrating behind
the profile.
1
Bonding
Comb the StoDeco Coll onto the
substrate and rustications using the
floating-buttering method. Press the
rustications onto the wall across the
entire surface. Full-surface bonding is
achieved by moving the rustications
gently back and forth.
Tip
Create the butt joint through a broken edge using a V bevel or all-around
edge formation, i.e. break the edges by means of light sanding.
2
After through-drying, remove any
remaining adhesive from the butt joints.
3
Depending on the desired surface texture,
prime with Sto-Primer (rough) or StoColor
Maxicryl (smooth).
The intermediate coating and top coats
are applied with StoColor Maxicryl.
The elements to be butted must be
chamfered on-site.
4
Dowel window sills and larger profiles in
accordance with the current system
specifications. Fix the profile with an
additional dowel approx. 20 cm from the
end of the profile. The dowel must be
recessed approx. 20 mm in the profile. Fit
a foam cap to the dowel head, then fill
and smooth the dowel punch hole with
StoDeco Coll.
Alternative: Fit a 5 mm thick StoDeco
Cap. Grind until smooth.
5
In order to achieve a surface texture
similar to sandstone, StoDeco Profiles are
pre-coated with Sto-Primer and then
twice top coated with StoColor Maxicryl.
A smooth surface can be achieved with
three coats of StoColor Maxicryl without
primer.

Note
Product tip
Starter tracks made of aluminium have a high thermal
conductivity. A plinth connection with the Sto-Starter
Track Universal shown here should therefore only be
used when the following conditions are satisfied:
• The basement is unheated.
• The cellar ceiling is insulated.
• The facade insulation ends approx. 50 - 80 cm below the height of
the cellar ceiling.
• The starter track is thermally separated from the wall structure by
means of packing shims or a thermal stop (e.g. Sto-Joint Sealing
Tape Lento).
Sto-Armour Mesh is a reinforced glass
fibre mesh. It increases the compressive
strength in critical areas (e.g. the

Windows and doors
Window connection general information
• Windows and doors must be fixed in accordance with the
latest technology in order to prevent undue movement.
The corresponding relevant guidelines (e.g. those provided
by the German RAL Quality Assurance Association for
Windows and Doors) must be observed.
• The substrate (e.g. window frame) must be level, dry, stable
and free of substances which can adversely affect the
adhesive bond (e.g. grease, dirt). Cleaning is advisable. An
adhesive sample section should be produced. In the case of
special (e.g. dirt-repellent) surface finishes, pre-treatment
may be required (after consulting the door or window
supplier).
• Only fix the seal beads immediately before installing the
adjacent insulation boards.
• If the length of the connection is less than 2.30 m (or
2.40 m with Sto-Seal Bead Milano), apply the seal beads in
one piece.
• If the length of the connection is longer, always use the
profile in its original length at the bottom and cut to size at
the top.
• In the corner area (window lintel), first place the vertical seal
beads in their maximum length and then install the horizontal
profile between the vertical profiles.
• Sto-Seal Beads may not be used for the connection of
windows that are flush with the rendered facade or for
window elements that protrude from the (finished) facade.

Scaffold anchors leave behind holes in
the insulated and rendered wall. Use the
Sto-Scaffold Plug made of impregnated
flexible foam to seal these scaffold anchor
holes.
If expansion joints are required in the construction, these must
also be formed within the EWIS. Both expanding joint tapes
and suspension profiles are used for this.

Note
The information up to page 46 also applies to the mineral external

on the following pages.
Bonding the insulation boards
Immediately after application of the bonding mortar (after 10
minutes at the latest), press, float into place and press-fit the
insulation boards. Depending on the weathering, this time
interval may be shorter. Excessive drying times of the bonding
mortar on the insulation board or wall lead to the formation of
a skin on the bonding mortar which can lead to adhesion
problems.
The insulation boards must be precisely applied in a bond.
There must be no open joints between the insulation boards.
Unavoidable gaps must be sealed with equivalent insulants.
In order to prevent thermal bridges, there must be no bonding
mortar in joints or between the board joints. Damaged insulation boards must not be installed.

Substrates
The Sto-Mineral Fibre Board must be dowelled. Dowels
meeting the European Technical Approval must be used for
this. The lamella insulation board can be additionally dowelled
in the case of load-bearing substrates. In the event of an
insufficient load-bearing capacity, the lamella insulation board
must also be fixed using dowels that meet the European
Technical Approval or national application guidelines.
Anchorage depth
The dowel must be anchored in the solid wall material at the
depth required by the relevant dowel approval. Tiles and old
render are not classed as suitable anchorage substrates.
Pull-out test
In the case of doubtful substrates, the pull-out strength has to
be determined through measurements on the object.

mortar to the wall
In the case of smooth substrates, apply an
adhesive bead in sinuous lines with a
max. spacing of 10 cm to the wall.

Dowel specifications
The dowel length depends on the existing wall structure and
the insulant thickness. The number of dowels depends on the
height and location (surface, edge). Dowelling is usually
located beneath the reinforcing coat or the reinforcing mesh.
Ensure an even dowelling pattern. Country-specific dowelling
patterns must be taken into account.
