Material Properties

  • Reaction to fire: German classification "not flammable" or "flame-retardant" depending on the Capatect ETICS type or the ventilated cladding system type.
  • Water vapour permeable
  • Excellent adhesion on all mineral substrates
  • Highly crack resistant
  • Easy to apply, due to lightweight aggregates
  • Especially economic due to quick application and low material consumption
  • Environmentally friendly
  • Basis of binder: white cement and white hydrated lime with low organic/silicate additives
  • Contains aggregates to promote waterproofing, easy application and good adhesion

Packaging/Package Size

25 kg bag, 700 kg container, 700 kg BigBag


Natural white.
Can be tinted by the manufacturer down to luminosity ≥ 30 according to the colour guides CaparolColor or Caparol 3D-System.

For more intense shades with a luminosity <30 to ≥ 20, paint with Capatect-SI-Fassadenfinish 130. (Luminosity < 20 is not suitable for Capatect ETICS)

Note: Depending on weather conditions tinted mineral renders/plasters may appear non-uniform (blushing) after drying. This does not cause any technical or functional deficiency and cannot be objected. To avoid colour deviation, paint tinted render/plaster additionally with Capatect-SI-Fassadenfinish in the matching colour shade.

Suitable Substrates

Reinforcement layers of Capatect ETICS A and B and ventilated cladding systems; mineral based new or existing mineral render of mortar group PII and PIII as per DIN V 18550.

Substrate Preparation

Reinforcement layer: Fresh prepared reinforcement layers are ready for application after complet curing. Prime weathered reinforcement layers with Capatect-Putzgrung 610. More weathered layers might need priming with Sylitol-Konzentrat 111 depending on absorption properties.

Mineral render/Plaster: The substrate must be even, clean, dry, solid, sound/stable and free from all substances that may prevent good adhesion.
Remove mildew, moss or algal attack by water jet cleaning in compliance with the regulations, followed by priming with Capatox and allow to dry well.
Clean surfaces contaminated with industrial gases or soot by water jet containing a suitable cleaning agent in compliance with the regulations. To reduce the risk of staining on coloured render/plaster, assure uniform drying of the substrate.

For other cases, see Technical Information "Untergründe und deren Vorbehandlung" / "Substrates and their Preparation"

Method of Application

Apply freshly prepared mortar by stainless steel trowel or suitable spraying equipment (for fine render application) homogeneously. Modelize, sponge-trowel or flush the surface while it is still fresh. Layer thickness should be between 2 and 5 mm.

The surface roughness depends on the used tool. Always use the same type of tool to achieve a uniform texture. Continuous surfaces should always be finished by the same craftsman (avoiding texture differences through different techniques). To avoid lapping, a sufficient number of workers should be present on each level of the scaffolding. Apply wet-on-wet and without interruption.

Fantasy-texturings should not differ to much in thickness to avoid cracks in the junctions.

On smoothed or washed textures a sinter layer can form, due to accumulation of binder on the surface. Also fine shrinkage cracks can not be avoided entirely. These effects are however not objectionable defects.

Being natural products, the aggregates and fillers may occasionally cause slight differences in colour. It is therefore recommended to use only material marked with identical batch numbers or, if using material from different batches, to mix the entire quantity needed in advance.

Surface Coating System

Priming or intermediate coats must be cured before any further application.


The consumption of fine grained and free structurable plaster depends on the texturing and may vary.

Application Conditions

Processing temperature:
+ 5 °C to + 30 °C during application and curing for Material, atmosphere and substrate.
Do not apply on sun heated substrates, during strong wind, fog or rain, high relative humidity or imminent rain and frost.

Drying/Drying Time

Cured and recoatable after approx. 2 weeks (at +20 °C / 65 % RH). Additional priming with CapaGrund Universal minimizes the risk of efflorescence and the finishing render/plaster is recoatable after approx. 7 days. The render/plaster dries by hydration and physically, i.e. by evaporation of water.
Lower temperatures and higher relative humidity extend the drying times.

Tool Cleaning

Immediately after use with water.

Material Preparation

Capatect mineral lightweight renders/plasters can be prepared with all common types of flow mixers, spiral pumps and plaster machines.
For manual preparation pour the mortar premix into the required amount of cold tap (potable) water while mixing thoroughly with a suitable low-speed electric paddle until the mixture is free of lumps. Allow the mortar to rest for about 5 minutes, then stir again. If necessary, adjust to working consistency by adding water.
Water consumption per 25 kg bag: approx. 10 l

Depending on weather conditions, pot life is approx. 1 to 1 1/2 hours. For machine use, the maximum time in the hose is 30 minutes. Already hardened (slightly stiff) material must not be made pliable by adding water and cannot be used.

Example for Machine Equipment

Follow  the guidelines of the manufacturer strictly!
Flow mixer Berö Calypso 15 with standard portioning or mixing spindles and feed pump.
Berö Speedy 15 with screw-conveyor1/1 output.
Electric-supply: Each 400 V rotary current /16 A (building current distributor with ELCB protection switch)
Water supply: 3/4" hose with GEKA connector, minimum 2.5 bar water pressure is required for the running machine
Flow of water: Approx. 350 litres/hour. The desired consistency can be set by the fine-regulating valve in the water-fitting of the mixer.
Feed tubes: First tubes - interior Ø 35 mm, 13.3 m each, End tube-interior Ø 25 mm, 10.0m
Max. range: Approx. 50 m (should be optimised depending on temperature and building conditions)
Spraying unit: Berö Integra Kombi; Nozzle size Ø 8 mm
Compressor: V-Meko 400 

Rinse the feed tubes before regular operation with lime slurry or paste,

Water consumption should be adjusted, if necessary. Especially for tinted renders/plasters consumption may vary. Always use the same amount of water to avoid irregularities in texture and shade.

Capatect-Modellier- und Spachtelputz (modeling and surface render) provides the necessary protection for normal load of algae or fungus. If a more extensive, preventive protection is desired, a double coat of ThermoSan is run. 

If necessary, cover the scaffoldings with tarpaulins to protect the surface from rain during the drying phase. Follow national or local regulations and specifications for application of mineral based mortars.

Protect carefully the environment of the surface to be coated, in particular, glass, ceramics, paint, brick, natural stone, metal and natural state or varnished wood. Cleaning up spills immediately with plenty of water. Capatect-Modellier- und Spachtelputz is not suitable for use on horizontal surfaces with water pollution.

Optional depending on weather conditions and absorbency: Prime the cured reinforcing layer with Sylitol Koncentrat 111 (diluted with tap water in a 2:1 ratio) before applying Capatect-Modellier- und Spachtelputz.
