Capatect AmphiSilan Fassadenputz FREE

Ready-to-use silicone resin textured render without biocidal film protection according to DIN EN 15824
LV Texte

Field of Application

Ready-to-use, texturable silicone resin plaster for mineral and organic exterior wall and ceiling surfaces without biocidal film protection. Can be used in conjunction with Capatect façade systems.

Material Properties

  • Without biocidal film protection
  • Highly permeable to water vapor
  • Water repellent
  • Smooth processing
  • Can be diluted with water
  • Graduated, lightfast pigment-filler-granulate combination

Packaging/Package Size

Bucket 25 kg

Colours

White and tinted

Factory tinting is possible. Suitable for machine tinting with ColorExpress dosing systems.
Further special shades with a light reflectance value > 20 available on request.

Tinting of small quantities is possible by adding CaparolColor (formerly Alpinacolor) or Amphibolin (formerly Amphibolin) (full-tone and tinting colours). Do not add more than 2% of colour, as otherwise the consistency becomes too thin.

The material must be checked for colour accuracy before processing.
Complaints about colour shades cannot be accepted after application.
Use material from the same batch number for coloured materials or contiguous surfaces.

Storage

Cool, protected from frost and avoid large temperature fluctuations. Protect from direct sunlight. Keep opened containers well closed.
Process material within 12 months.

The consumption figures are guide values without loss of bulk or shrinkage. Building-dependent or processing-related deviations must be taken into account.

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, VHF or the products and the Technical Informations of the products must be observed.

Suitable Substrates

  • Mineral and organically bound renders and paints
  • Mineral and organically bound 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 undercoat renders, must be evenly dried to avoid colour deviations in the finishing render.
Before applying the decorative render, we recommend priming with Putzgrund 610, coloured if necessary, to improve the application and accelerate the film formation of the finishing render, especially on fresh mineral base coats.

Preparation of Material

Ready to use.
Adjustable to working consistency with max. 2 % water.
Stir the contents of the container thoroughly with a slow-speed agitator.

Method of Application

Apply the render over the entire surface using a stainless steel trowel and smooth it down to the grain. Immediately afterwards, use a plastic trowel or a plastic float to spread it evenly in a circular motion.
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 build-up in the textured layer. Divide large façades into sections, wet-on-wet apply and texture continuously.
Due to the use of natural fillers and granules, slight colour variations are possible. Therefore, only use material with the same batch number on contiguous surfaces, or mix material from different batches beforehand.

Surface Coating System

The risk of attack by micro-organisms can be significantly reduced by using a facade paint that has been treated with a film protection agent.

If the light reflectance value is below 20, after the render has dried, coat the render in the ETICS with a solar-reflecting facade paint (CoolProtect, TSR value ≥ 25) in at least two layers, depending on requirements. On solid wall structures, special measures are to 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, additionally a solar-reflecting facade paint with TSR ≥ 25.
Note the limits of feasibility in the respective system.

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. In this context, we 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 Facades).
In unfavourable weather conditions, suitable measures must be taken to protect the treated façade 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.
The drying or curing of the material takes place through chemical-physical processes and the release of the water it contains, i.e. its evaporation. Cool and humid environments delay these processes.

  • Surface dry after approx. 24 h
  • Completely dry, loadable and paintable after approx. 48 hours

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

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

    Conveying distances:
    Maximum delivery distance approx. 50 m; delivery head 30 m
    (depending on temperature and device)

    Sprayer:
    Nozzle Ø dependent on the grain size

    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.

Note

This product is equipped with special active substances against fungal and algae growth. The depot of active substances offers long-lasting, temporary protection, the duration of which depends on the object conditions, e.g. the moisture load, the location, the architectural design, etc.. It is therefore not possible to permanently prevent fungal and algae growth. The risk of infestation by microorganisms can be significantly reduced by applying a facade paint with film protection.

Special Risks (Hazard Note) / Safety Advice (Status as at Date of Publication)
