Substrate Preparation
Mask window sills and add-on parts. Carefully cover glass, ceramics, clinker, natural stone, painted, glazed and anodised surfaces as well as surfaces to be protected.
Any offsets at the joints of EPS rigid foam boards must be sanded down beforehand. Any adhering sanding dust must be removed.
The substrate must be solid, dry, free of grease and dust and, in dowelled systems, have sufficient load-bearing capacity for the use of anchors. Contamination and substances with a separating effect (e.g. formwork oil) as well as protruding mortar ridges must be removed. Damaged, flaking paintwork and decorative render must be removed as far as possible. Hollow areas of rendering must be knocked off and rendered flush with the surface. Highly absorbent, sanding or flouring surfaces must be thoroughly cleaned down to the solid substance and primed.
The compatibility of any existing coatings with the material must be expertly checked.
Preparation of Material
The material is ready to use. Stir up shortly before application. In warm weather, it is possible to adjust the consistency by adding a little water.
Consumption
Bonding of insulation boards
approx. 3.0-6.0 kg/m2
Base coat
approx. 1.3 kg per mm layer thickness per m2
(e.g. corresponds to approx. 5.2 kg/m2 with 4 mm layer thickness)
These consumption figures are approximate values.
Deviations depending on the object or processing conditions must be taken into account.
Application Conditions
During the application and in the 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. Please refer to the leaflet "Verputzen, Wärmedämmen, Spachteln, Beschichten bei hohen und tiefen Temperaturen" (Rendering, Thermal Insulation, Filling, Coating at High and Low Temperatures) from the Bundesverband Ausbau und Fassade (Federal Association for Finishing and Façades).
In unfavourable weather conditions, take suitable measures to protect the facade surfaces being treated.
Drying/Drying Time
Bonding
Depending on the weather, after approx. 2-3 days at the earliest, insert wall plugs and apply the base coat.
Base coat
At 20°C and 65% relative humidity, the reinforcing render layer is surface-dry after 24 hours, thoroughly dry and can be loaded after approx. 3 days. Before further processing, the material must be checked for sufficient drying throughout the entire layer thickness. The render dries physically through the evaporation of moisture. Therefore, drying is delayed particularly in the cool season and at high humidity.
The organic mortar must not be reworked with mineral renders.
If it is not possible to ensure that the minimum application temperatures are maintained, there is the option of using alternative products for wet and cold weather. For more information on this product group, please request advice.
Tool Cleaning
Rinse with water immediately after use in accordance with legal regulations.Example for Machine Equipment
- Feed pump e.g. m-tec P 25 V, Inotec InoBeam F30
Delivery hoses:
Start hoses, inner Ø 35 mm; end hose, inner Ø 25 mm
Conveying distances:
Maximum delivery distance approx. 50 m; delivery head 20 m
(temperature- and device-dependent)
Sprayer:
Nozzle-Ø 8-10 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).
Follow the machine manufacturer's instructions.
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 %
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.
Machine 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 %
Reinforcement Layer
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, embed additional Capatect Diagonalarmierung 650/00 (diagonal reinforcement strips), Capatect Sturzeckwinkel (lintel corner profile) or fabric strips (approx. 25 x 25 cm) diagonally into the base coat.
- Insert plastering strips, Capatect Gewebeeckschutz 656 (mesh corner protection) and profiles into the base coat over the entire surface and align. When using Capatect Gewebeeckschutz 656 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 Capatect Gewebe 650 or 666 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.
Application
Layer thickness:
EPS insulation: 2-5 mm
