The consumption data are approximate values without bulk and shrinkage loss. Object-dependent or processing-related differences must be taken into account.

Note

The data given represents average values, which 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, VHF or the products and the Technical Information of the products must be observed.

Suitable Substrates

  • Mineral-based renders
  • Mineral-based substrates in ETICS

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.

The substrate must be stable, even, clean, dry, frost-free and free of adhesion-reducing residues. If necessary, the load-bearing capacity can be ensured by using suitable primers.
Substrates, especially base coats, must be evenly dried to avoid colour deviations in the finishing render.
For better workability, we recommend priming with Putzgrund 610 before applying the decorative render.

Preparation of Material

The material can be mixed to a lump-free mass using a powerful, slow-running agitator 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 approx. 1.5 hours (pot life).
Do not use water to make material that has already hardened workable again.

Method of Application

Thin-layer finishing renders with grain sizes < 3 mm may require special measures, e.g. priming, levelling filler, painting.

Apply the finishing render over the entire surface with a stainless steel trowel and smooth down to grain size. Immediately afterwards, rub down evenly with a plastic trowel or a plastic rubbing board and texture the render.

Structure sraped render horizontally, vertically or round.

The choice of tool influences the roughness profile of the surface, so always work with the same textured discs.
Finish contiguous surfaces without interruption to avoid lapping in the textured layer. Divide large façades into clauses, apply continuously wet-on-wet and texture.

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

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 65 % relative humidity and serve as a guide. Dark colours of the finishing render may require special measures.
The base coat must be sufficiently evenly dried.

Waiting time after base coat

  • Mineral renders at least 1 day per mm layer thickness, at least 7 days

An additional priming coat of CapaGrund Universal reduces the risk of lime efflorescence.

Tool Cleaning

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

Coating

Due to their special properties, deviations in colour shade and staining cannot always be avoided with coloured mineral renders. This does not constitute a technical-functional defect and cannot be objected to.
In order to avoid colour irregularities, coloured plaster surfaces must also be finished with a levelling coat or a suitable façade paint in the colour of the plaster.

The risk of infestation by microorganisms can be significantly reduced by applying a facade paint with film protection.

For light colour values below 20, the render in ETICS must be coated with at least two layers of a solar-reflective façade paint (Caparol CoolProtect with TSR value ≥ 25) after drying.
On massive wall structures, special measures must be taken for LRV < 30, e.g. an additional reinforced base coat with full-surface fabric inlay on the lightweight base coat; for LRV < 20, an additional solar-reflecting facade paint with TSR ≥ 25.

Note the limits of feasibility in the respective system.

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).
Follow the machine manufacturer's instructions.

It is recommended to seek advice on the use of silo and machine technology. Further information on this can be found in the Caparol "Handbuch der Spritztechnologie" (Spray Technology Manual).
