Packaging/Package Size

Natural white.
Can be tinted by the manufacturer down to luminosity ≥ 20 according to the colour guides CaparolColor or Caparol 3D-System. For more intense shades with a luminosity <20, paint with Sylithol Finish 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 additionally with Sylithol Finish 130 in the matching colour shade.

Without spilling or loss on site. May vary according to substrate or application conditions. The exact rate of consumption is best established by a trial application.

Suitable Substrates

Reinforcement layers of Capatect ETICS A and B; uncoated concrete, mineral based new or existing mineral render of mortar group PII and PIII as per DIN 18550. Interior: gypsum board and mineral render of mortar group P IV and P V.

Substrate Preparation

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

Uncoated concrete, mineral render or 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, 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 to the complete surface and rub down to the particle size. Then treat the surface with a PU board or a wooden trowel, a sponge- trowel or a plastic board by circularly, vertically or horizontally smoothing. The surface roughness depends on the used tool. Always use the same type of tool to achieve a uniform texture.
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.

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.

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 is recoatable after approx. 7 days.
The render 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

Water consumption per 25 kg bag: approx. 5.5 - 6.5 l

Capatect mineral lightweight renders can be prepared with all common types of flow mixers, spiral pumps and plaster machines. Maximum pot life for mechanic conveyance: 60 min.

For manual preparation pour the mortar premix into the required amount of cold tap 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 2 minutes, then stir again. If necessary, adjust to working consistency by adding a little bit of water.
Depending on weather conditions, pott life is approx. 2 hours for manual preparation.
Already hardened, slightly stiff material must not be made pliable by adding water and cannot be used.

Example for Machine Equipment

Flow mixer Berö Calypso 15 with standard portioning or mixing spindles and feed pump.
Berö Speedy 15 with screw-conveyor 1/1 output.
Electric-supply: Each 400 V rotary current /16 A (via site distributor with RCCB protection)
Water supply: 3/4" hose with GEKA connector, minimum 2.5 bar water pressure is required for the running machine
Flow of water:
CT-Mineralputz R20: approx. 250 l/h    CT-Mineralputz R30: approx. 240 l/h
CT-Mineralputz K20: approx. 290 l/h    CT-Mineralputz K30: approx. 290 l/h
CT-Mineralputz K50: approx. 240 l/h    
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
Note: Water consumption should be adjusted, if necessary, depending on used equipment. Especially for tinted renders/plasters consumption may vary. Always use the same amount of water to avoid irregularities in texture and shade.

Capatect-Mineralputz 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-Mineralputz 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-Mineralputz.
