White and coloured.
Factory tinting is possible. Suitable for machine tinting with ColorExpress dosing systems.

Note
The information provided represents average values, which may vary slightly from delivery to delivery due to the use of natural raw materials.Please note the general building authority approval/general type approval and the technical information for the systems/products involved.
The information refers to white goods or standard goods. Deviations are possible due to colour tinting.
Suitable Substrates
- Mineral substrates, e.g. renders from CS II according to DIN EN 998-1 (compressive strength min. 1.5 N/mm2) or from PIc according to DIN 18550
- Pasty (organic) base coats and fillers
- Can be used in ETICS and VHF, in solid construction and renovation
The substrate must be sound, level, clean, dry, frost-free and free of substances that could impair adhesion. To achieve colour-uniform coatings, ensure that the substrate has uniform absorbency.
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.
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.
Protective measures
Mask off window sills and trim. Use only UV-resistant tape for outdoor use.
Carefully cover glass, ceramics, clinker brick, natural stone, painted, glazed, anodised and surfaces to be protected. Immediately remove splashes with water.
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).
The waiting time before applying a new coat of plaster 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.
- Waiting time for organic finishing coats on new mineral base coats: min. 1 day per mm layer thickness, but min. 5 days.
- Waiting time for organic finishing coats on new organic base coats: after complete drying, min. 2-3 days.
Old mineral plasters, concrete:
Moderately absorbent: CapaGrund Universal diluted with up to 3% water.
Highly absorbent, chalking, or sandy: Prime with OptiSilan TiefGrund or Dupa-Putzfestiger.
If necessary, apply an intermediate coat of Caparol PutzGrund 610.
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 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.
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 Façades).
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. At low temperatures and high humidity, the drying time is extended.
The figures are based on 20 °C and 65% relative humidity and are provided for reference only.
Recoat after the surface is completely dry.
- Surface dry after approx. 24 h
- Hardened, durable and painted over after approx. 2-3 days
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
(temperature- and device-dependent)
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. Consultation on the use of silo and machine technology is recommended.
Note
In the transition area between the ground-contact surface and the base, or in similar areas exposed to splashing water, apply a suitable moisture barrier (e.g., SockelFlex or SockelFlex Carbon) to the finishing render, extending at least 5 cm above ground level.
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 deposit of active substances against microbiological infestation in coatings offers long-lasting but temporary protection. 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.
