Note

Specified fixed values represent average values that may vary slightly from delivery to delivery due to the use of natural raw materials.
The "allgemeine bauaufsichtliche Zulassung" (general building authority approval) / "allgemeine Bauartengenehmigung" (general type approval) of the ETICS or VHF and the product and the data sheets of the products must be observed.

Suitable Substrates

Substrates in accordance with the specifications of the ETICS approvals, e.g. coated mineral substrates, solid old plaster, wood and board materials, insulating materials.
Can be used in ETICS and VHF, in solid construction and in renovation.

The substrate must be frost-free, solid, dry, free of grease and dust and, for anchored ETICS systems, have sufficient load-bearing capacity for the use of anchors. It must have the flatness required for the planned ETICS.
The compatibility of any existing coatings with the adhesive mortar must be checked.
Observe VOB, Part C, DIN 18345, Section 3.
Please refer to Caparol Technical Information No. 650 - Untergründe und deren Vorbehandlung (‘Substrates and their pre-treatment’).

Substrate Preparation

Mask off window sills and add-on parts. Carefully cover glass, ceramics, clinker, natural stone, painted, glazed and anodised surfaces.
The substrate must be solid, dry, free of grease and dust and, if necessary, have sufficient load-bearing capacity for the use of anchors.

The substrate must be firm, dry, free of grease and dust and, if necessary, have sufficient load-bearing capacity for the use of anchors. Remove dirt and substances with a separating effect (e.g. formwork oil) as well as protruding mortar burrs. Damaged, peeling paints and textured plasters must be removed as far as possible. Hollow areas of plaster are to be knocked off and flush with the surface.
Highly absorbent, sanding or chalking surfaces must be thoroughly cleaned down to the solid substance and primed.
The compatibility of any existing coatings with the material must be checked by an expert.

Preparation of Material

25 kg material (one bag) in approx. 6.0 - 6.5 l water.

The material can be mixed to a lump-free mass using a powerful, slow-running stirrer or compulsory mixer and clean, cold water.

Work through again after approx. 3-5 minutes. If necessary, adjust the consistency with a little water after this maturing time.
Depending on the weather, the working time is up to 1.5 hours (pot life).
Do not use water to make material that has already set workable again.

Consumption

Bonding of insulating boards
- approx. 4.5 - 6.0 kg/m²

Base coat:
- approx. 1.5 kg per mm layer thickness per m²
(e.g. corresponds to approx. 6.0 kg/m² with a layer thickness of 4 mm)

These consumption figures are approximate values.
Deviations depending on the object or processing conditions must be taken into account.

Layer thickness of the base coat: 3-5 mm

Application Conditions

During the application and drying phase, the ambient and substrate temperatures must not be below +5°C and above +30°C.Do not apply in direct sunlight, strong wind, fog or high humidity.
In this context, we refer to the leaflet "Verputzen, Wärmedämmen, Spachteln, Beschichten bei hohen und niedrigen Temperaturen" (Rendering, Thermal Insulation, Filling, Coating at High and Low Temperatures) from the Bundesverband Ausbau und Fassade (Federal Association for Finishing and Facades).
In case of unfavourable weather conditions, take suitable measures to protect the processed facade surfaces.

Drying/Drying Time

Primer and intermediate coats must be dry before further application.
The waiting time for recoating depends, among other things, on the weather conditions and the layer thickness. The specifications refer to ambient temperatures of 20 °C and 60 % relative humidity and serve as a guide.
Any necessary anchoring or base coat should only be applied after the adhesive bed has sufficiently solidified.

Waiting time after bonding

Anchoring at least 24 hours
Base coat approx. 3 days

Waiting time after base coat

Mineral finishing coat: up to 5 mm layer thickness from the base coat, at least 2 days, above that at least 1 day/mm layer thickness
Organic finishing coat: 1 day/mm layer thickness from the base coat, but at least 5 days

Tool Cleaning

Rinse with water immediately after use in accordance with legal regulations.

Example for Machine Equipment

Continuous mixer e.g. inoMIX F51 or m-tec D10
Feed pump e.g. m-tec P 25 V
Mixing pump e.g. InoCOMB Maxi power or PFT G4

Delivery hoses:
Start hoses, inner Ø 35 mm; end hose, inner Ø 25 mm

Conveying distances:
Maximum delivery distance approx. 30 m; delivery head 20 m
(depending on temperature)

Sprayer:
Nozzle-Ø 8-12 mm

Pre-flush delivery hoses with lime slurry or paste before regular operation.
If work is interrupted, do not leave the delivery hose in direct sunlight, cover the material container with foil, for example, and keep the gun and nozzle under water. Stand for max. 30 min. until further processing, otherwise the material in the hose may harden.
Before a work break, the material container in the feed pump of the ‘open system’ (continuous mixer + feed pump) must be emptied as far as possible to prevent material tunnelling when restarting. If this is not observed, the material may have to be made ‘passable’ before the machine is started up (with the machine switched off). Further information on this can be found in the Caparol "Handbuch der Spritztechnologie" (Spray Technology Manual).
The specifications of the machine manufacturer must be observed. Consultation on the use of silo and machine technology is recommended.

Bonding of Insulation Boards

Manual or mechanical application possible
Lay insulation boards at least 10 cm staggered in a bond and join tightly
Butt and bed joints must remain free of adhesive
Fill joints ≤ 5 mm with suitable flame-retardant joint foam
Close joints and gaps > 5 mm with equivalent insulation strips
Interlock insulation materials at the corners of the building
Ensure that the application is flush and plumb
Pre-fill uncoated mineral wool insulation boards in the bonding area (press-filling)
Damaged insulation boards must not be installed

Bead-dot method
Apply a circumferential bead to the edge of the board and adhesive dots in the centre.

Render systems - adhesive contact area ≥ 40 %
Hard surface systems - adhesive contact area ≥ 60%

Full-surface bonding
On even substrates, the adhesive can be applied over the entire surface using a notched trowel/notched trowel. The insulation boards must be pressed, floated and pressed onto the substrate immediately, after 10 minutes at the latest, with the side to which the adhesive was applied.
Mineral wool lamella insulation boards must always be bonded over the entire surface.

Mechanical bonding (partial surface method)
Apply the material to the substrate by machine in the form of vertical beads. The adhesive beads must be approx. 5 cm wide and at least 10 mm thick in the centre of the bead. The centre-to-centre distance must not exceed 10 cm. The insulation boards must be pressed, floated and pressed into the fresh adhesive bed immediately. To avoid skin formation, only as much adhesive surface may be applied as can be laid directly with insulation boards.

EPS boards - adhesive contact area ≥ 60 %
Mineral wool insulation boards - adhesive contact area ≥ 50 %
Hard surface systems - adhesive contact area ≥ 60%

Reinforcement Layer

Dark colours of the top coat may require special measures in the base coat (e.g. minimum layer thicknesses, two fabric inserts).

Level out thickness and height irregularities or weathered surfaces of EPS/PUR by sanding and remove sanding dust.
To ensure a uniformly even surface and to stabilise the insulation surface of mineral wool insulation boards, we recommend levelling before applying the base coat. To do this, pre-fill a first layer with the reinforcing mortar to a thickness of approx. 2 mm and allow to dry thoroughly.
In the corner area of building openings, additionally embed Capatect Diagonalarmierung, Sturzeckpfeil or fabric strips (approx. 25 x 25 cm) diagonally into the base coat.
Insert plastering strips, corner beads and profiles into the base coat over the entire surface and align. When using Capatect Gewebeeckschutz, only guide the mesh strips up to the edge.
Apply the base coat with a stainless steel trowel or by machine. Check the layer thickness with an appropriate notched trowel. The thickness of the base coat must be uniform.
Embed the mesh over the entire surface so that it is centred for reinforcement layer thicknesses up to 4 mm and in the upper third above 4 mm.
Joints of the mesh must be overlapped by approx. 10 cm.
Subsequently fill over wet-on-wet to ensure full coverage of the mesh.
