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.
The information refers to white goods or standard goods. Deviations are possible due to colouring.
Suitable Substrates
- Mineral-bound base coats and fillers from CS II in accordance with DIN EN 998-1 (compressive strength min. 1.5 N/mm2) or from PIc in accordance with DIN 18550
- Mineral-bound substrates in ETICS in accordance with approvals
- Can be used in ETICS and VHF, in solid construction and renovation
- Suitable for indoor and outdoor use
Observe VOB, Part C, DIN 18350 and 18345, Section 3. The substrate must be tested in accordance with information sheets No. 20 and 20.1 issued by the Bundesausschuss Farbe und Sachwertschutz e.V. (Federal Committee for Paint and Material Protection).
Substrate Preparation
Please refer to Caparol Technical Information No. 650 (Untergründe und deren Vorbehandlung" (‘Substrates and their pre-treatment’).
The following information is provided as an example and is not exhaustive. Plastering work is carried out after any necessary substrate preparation.
Protective measures:
Fensterbänke und Anbauteile abkleben. Only use UV-resistant adhesive tape outdoors.
Glas, Keramik, Klinker, Naturstein, lackierte, lasierte, eloxierte und zu schützende Flächen sorgfältig abdecken.
Cleaning/priming the substrates:
Clean dirty areas and remove unstable layers using a suitable method.
If necessary, the stability of the substrate can be ensured by using suitable primers (strengthening, absorbency-regulating, adhesion-promoting).
Thin-layer finishing plasters with grain sizes < 3 mm may require special measures to be taken on the substrate, e.g. priming, levelling filler.
Before applying the top coat, we recommend priming with PutzGrund 610 to improve adhesion, extend the open time and improve the workability of the top coat, especially on fresh mineral base coats. If possible, the primer should be tinted to match the colour of the final coat.
If left standing for a longer period of time (e.g. over winter), weathered base coats generally require a priming of PutzGrund 610.
The waiting time before applying a new coat of render depends, among other things, on weather conditions and the thickness of the coat. The information provided refers to 20 °C and 65 % relative humidity and is intended as a guide. At low temperatures and high humidity, the waiting time is longer.
- Drying time for mineral/silicate finishing renders on new mineral base coats: at least 2 days.
- For base coat thicknesses > 5 mm and on new mineral lightweight base coats in monolithic construction: at least 1 day per mm of base coat thickness.
Repaired areas must be well bonded and dry.
Coarsely porous, absorbent, slightly sandy: Apply a base coat of OptiSilan TiefGrund, CapaSol RapidGrund or Sylitol RapidGrund 111.
Highly sandy, chalky: apply a base coat of OptiSilan Tiefgrund, Dupa-Putzfestiger or Sylitol RapidGrund 111.
Method of Application
Apply the finishing render over the entire surface using a stainless steel trowel or a machine, and pull it to the desired grain size. Immediately afterward, smooth it out evenly using a plastic trowel or a plastic finishing board in circular motions.
Use a scraper to remove the scraped render in horizontal, vertical, or circular motions.
The choice of tool influences the roughness profile of the surface, so always work with the same textured discs.
Finish contiguous areas without interruption to avoid marks in the textured layer. Divide large areas into sections, apply wet-on-wet continuously 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 Facades).
In unfavourable weather conditions, take suitable measures to protect the facade surfaces being treated.
Drying/Drying Time
Primer coats must be dry before further work is done, and plaster must be sufficiently hardened.
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.
New mineral-based renders:
- Guideline: Allow a curing time of at least 1 day per mm of total layer thickness (base and finishing render combined), but no less than 14 days. Longer curing times reduce the risk of efflorescence.
- Applying a primer coat of CapaGrund Universal reduces the risk of efflorescence in mineral finishing renders, allowing application after a curing time of at least 7 days. Alternatively, mineral plasters can be coated with Sylitol Finish 130 (-W).
- Specially tinted finishes may require additional measures (e.g., longer curing times for the plaster substrate, priming with CapaGrund Universal, weather protection).
Tool Cleaning
Rinse with water immediately after use in accordance with legal regulations.
Coating
Due to their specific properties, slight variations in color and the formation of stains cannot always be avoided in colored mineral and silicate plasters. This does not constitute a technical or functional defect and cannot be grounds for a complaint.
To avoid color inconsistencies, coat the plaster after it has dried thoroughly with a suitable exterior paint or, at a minimum, with a leveling coat (e.g., Sylitol Finish 130).
Facade surfaces that are exposed to higher than normal levels of moisture due to specific building conditions or natural weathering are at increased risk of mould and algae growth. The product is alkaline and therefore provides natural, though temporary, protection against microbial growth. Applying a façade paint equipped with film protection can significantly reduce the risk of infestation by microorganisms. Permanent prevention of fungal and algae growth cannot be guaranteed.
Light Reflectance Value (LRV): Dark colours with low LRV may require special measures. Observe application limits in the respective system, e.g. in ETICS or from stone manufacturers.
For LRV values between 10 and 20, the render in ETICS with EPS or mineral wool must be coated with a solar-reflective facade paint with a TSR value ≥ 25 in at least two layers after thorough drying, depending on requirements (Caparol CoolProtect).
On monolithic, highly thermally insulated wall structures, special measures must be taken if LRV < 30, e.g. an additional mineral reinforcement render with full-surface fabric reinforcement on the lightweight base coat; if LRV < 20, a solar-reflective facade paint with TSR ≥ 25 must also be applied.
Repairs to the surface may be more or less visible, even when using the original coating material. According to BFS Fachregel (Techhnical rule) No. 25, visible marks are unavoidable. Whether a repair is perceived as visually disturbing depends on many factors, e.g. colour tone, gloss level, layer thickness, substrate, lighting.
Protect horizontal surfaces with special measures, e.g. metal covers.

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.
Material Preparation
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.
