Colours
White.
Further colour shades can be tinted via "ColorExpress". Available tinted at the factory for orders of 100 litres and more in one colour shade and application.
In order to detect possible tinting errors, please check for colour accuracy before processing. In case of conspicuities or deviations from the delivery target (e.g. colour deviations) or from the usual quality, please also observe the guidelines on inspection obligations for delivery of tinted products of the "Verband für Dämmsysteme, Putz und Mörtel e.V. (VDPM)" (Association for Insulation Systems, Plaster and Mortar): Brochures and leaflets - VDPM.
Only use colour shades of one production (batch) on continuous surfaces. "AmphiSilan" can also be tinted with suitable "AmphiColor Volltonfarben". In case of self-tinting, mix the required total quantity to avoid differences in colour shade. Intense colours may have a lower hiding power. It is therefore advisable to apply a comparable, opaque, white-based, pastel colour shade first. A second top coat may be necessary.

Suitable Substrates
The substrates must be free from dirt, separating substances and dry. In Germany observe "VOB, Part C, DIN 18363, Para. 3".
For substrate pre-treatment, please also observe our Technical Information No. 650 "Substrates and their pre-treatment".
Substrate Preparation
New and existing, intact external thermal insulation composite systems (ETICS) with surfaces made of synthetic resin, silicone resin, lime-cement render/ solid mortar class according to DIN EN 998-1 class CS II 1.5 - 5.0 N/mm2:
Old renders can be wet cleaned using a suitable method. When cleaning, use pressure water jets with a max. temperature of 60 °C and a max. pressure of 60 bar. Allow sufficient drying time after cleaning. Apply coatings of Caparol materials according to the existing finishing render type and the following substrate specifications.
Finish renders according to DIN EN 998-1 class CS II 1.5 - 5.0 N/mm2:
New renders are to be applied after sufficient standing time, usually after 2 weeks, at approx. 20 °C and 65 % rel. Humidity, they can be coated. In case of unfavourable weather conditions, e.g. influenced by wind or rain, significantly longer standing times must be observed. By applying an additional priming coat of "CapaGrund Universal" reduces the risk of lime efflorescence with alkaline finishing renders, so that coating can be applied after a standing time of only 7 days.
Old renders:
Renewd renders/ touch-ups must be well set and dried. Prime coarsely porous, absorbent, slightly sanding plasters with OptiSilan TiefGrund. Prime very sandy, chalky plasters with Dupa-Putzfestiger.
New silicate finishing renders:
Prime with Sylitol® NQG-W facade paint.
New silicate finishing renders:
Coat with products from our silicate Sylitol® products.
Old mineral paints and renders:
Clean firmly adhering coatings mechanically or by pressure water jetting in compliance with the legal regulations. Remove non-sticking, weathered coatings by scraping, sanding, scraping off. Apply one priming coat of "Dupa-Putzfestiger".
Load-bearing/ stable dispersion plaster and silicone resin plaster coatings:
Clean old renders with a suitable method. In case of wet cleaning, allow the surfaces to dry thoroughly before further treatment. Prime with "CapaGrund Universal" or "Dupa-Putzfestiger". Coat new synthetic resin or silicone resin renders without pre-treatment.
Sound dispersion, dispersion-silicate or silicone resin paint coatings:
Clean old coatings by pressure water blasting in compliance with the legal regulations. Observe substrate test according to BFS✱ Leaflet No. 20.
Old coatings with the following properties :
Weakly absorbent, solid, dry, load-bearing:
See coating structure.
Moderately absorbent:
"CapaGrund Universal" diluted with max.3% water.
Highly absorbent:
"OptiSilan TiefGrund" or "Dupa-Putzfestiger".
Old coatings on ETICS:
Highly absorbent, firmly adhering, fine hairline cracks:
Dupa-Putzfestiger.
Chalking or powdery:
(also under water load following BFS✱ No. 20, B.13 "Oberflächenfestigkeit, Kreidung"(Surface strength, chalking)):
Prime with "Dupa-Putzfestiger".
Glossy and water-repellent (hydrophobic) surfaces:
Mechanically roughen. Prime with "CapaGrund Universal". If water beading is still present after mechanical roughening, we recommend a priming coat of "Dupa-HaftGrund".
Non-bearing paint and render coatings:
Remove completely with a suitable method, e.g. by sanding, brushing, scraping, stripping and subsequent cleaning with pressurised water jets in compliance with legal regulations or other suitable measure. In case of wet cleaning, allow the surfaces to dry thoroughly before further treatment. Prime chalky, sanding, absorbent surfaces with "Dupa-Putzfestiger".
Facing brickwork:
Only frost-resistant facing bricks or clinker without foreign inclusions are suitable for painting. The masonry must have crack-free joints and be free of salt. Prime with "Dupa-Putzfestiger". Intermediate coat with "Minera Universal". If brown discolouration occurs after the intermediate coat with "Minera Universal", apply the final coat with "Duparol".
Sand-lime brickwork:
Only frost-resistant facing bricks that do not contain any driving or discolouring foreign inclusions such as sand or clay are suitable for painting. The jointing must be free of cracks. Clean chalking/flouring surfaces. Brush off salt efflorescence dry. Please observe BFS✱ Leaflet No. 2. Prime with "OptiSilan TiefGrund". Intermediate coat with "Minera Universal".
Surfaces with salt efflorescence:
Remove salt efflorescence dry by brushing. Apply one priming coat of "Dupa-Putzfestiger". When coating surfaces with salt efflorescence, no guarantee can be given for the permanent adhesion of the coating or the prevention of salt efflorescence.
Defects:
Repair small defects with "Caparol Fassaden-Feinspachtel". Large defects up to 20 mm should preferably be repaired with "Histolith-Renovierspachtel". Re-priming of filler areas.

Method of Application
Only to be applied with special Nespray airless equipment:
Spray application with Nespri nozzles for facade coating (spraying & re-rolling):
20° double nozzle 215 (for trimming work)
30° double nozzle 317 (for smooth substrates)
30° double nozzle 319 (for rough substrates)
The product temperature is automatically controlled by the Nespray airless unit.
Spray pressure (opened pistol) of "Nespri-Airless unit" is in the green marked field of indicator (manometer/pressure gauge).
When using the "NespriKIT-Schlauchtrommel" (hose reel) the spray pressure must be adjusted on the particular airless unit, on the responsibility of the workman.
Other coating materials, in particular primers, can also be applied with the Nespray airless unit, but a spray dust reducing (mist-free) effect cannot be guaranteed. Apply those materials with corresponding precautions.
Surface Coating System
Apply intermediate and top coat undiluted with the special Nespri equipment and immediately re-roll evenly with a commercial facade roller.
In the case of well-maintained, load-bearing old coatings, a single overcoat with a minimum consumption of 350 ml/m2 is sufficient in many cases. Allow at least 12 hours drying time between coats.
Consumption
approx. 200-250 ml/m2
The consumption values apply to one coat on a smooth surface. On rough surfaces, the consumption increases accordingly. Determine exact consumption by trial coating.
To achieve the best possible protection against algae and fungal attack, it is necessary to apply two coats with a total of at least 400 ml/m2 to achieve an average layer thickness of at least 200 µm.
Application Conditions
Lower temperature limit during application and drying:
Material, circulating air and substrate temperature: min. + 5° C to max. + 30°C.
Drying/Drying Time
At +20 °C and 65 % relative humidity surface-dry after 2 - 3 hours and recoatable after 12 hours. Completely cured and ready for stress after approx. 3 days. Lower temperatures and higher humidity extend the drying time.Tool Cleaning
Clean work equipment with water after use, observing the legal regulations.
Note
To avoid laps, coat larger surfaces wet-on-wet in one go. Do not use on horizontal surfaces exposed to water. There is an increased risk of fungus and algae formation on façade surfaces that are exposed to higher than usual moisture loads under special object conditions or due to natural weather influences.
In the case of dark colour shades, mechanical stress can lead to light streaks (writing effect). AmphiSilan reduces this characteristic, which is specific to all matt facade paints.
In the case of dense, cool substrates or in the case of drying delays due to weather conditions, auxiliary substances may form yellowish/transparent, slightly glossy and sticky run-off marks on the surface of the coating due to exposure to moisture (rain, dew, fog). These auxiliary substances are water-soluble and are removed independently with sufficient water, e.g. after several heavy rainfalls. The quality of the dried coating is not adversely affected by this. If, nevertheless, a direct recoating should be carried out, the runners/auxiliary materials must be pre-wetted and washed off completely after a short exposure time. Apply an additional priming coat of "CapaGrund Universal". If the coating is applied under suitable climatic conditions, these run-off marks will not occur.
Markings of touch-ups/ repairs in the surface depend on many factors and are therefore unavoidable (observe BFS✱ Leaflet No. 25).
Copper run-off (CU ions in rainwater) reacts with ingredients of AmphiSilan to form brownish discolourations. Therefore, corresponding copper surfaces must be protected against oxidation. Alternatively, our products "ThermoSan NQG" or "Muresko" can be used.
