Field of Application
Mineral lightweight rendering mortar according to DIN EN 998-1 in the Capatect façade systems, as well as on all load-bearing mineral wall and ceiling surfaces indoors and outdoors, e.g. the Capatect interior insulation systems or the render systems for monolithic construction. Do not use on surfaces exposed to extreme mechanical loads.
- Smooth and safe application due to lightweight aggregates
- Water vapour permeable
- Excellent adhesion to all mineral substrates
- High crack resistance
- Especially economic due to quick application and low material consumption
- Environmentally friendly
Packaging/Package Size25 kg bag, 600 kg OWC container
Factory colouring up to light reference value ≥ 30 according to the colour chart CaparolColor or the Caparol 3D-System is possible.
If, for design reasons, more intensive colour shades with light reference value < 30 to ≥ 20 are desired, these are to be created by painting over with "Sylitol® Finish 130".
Coloured mineral renders may dry cloudy depending on the weather. This does not represent a technical-functional defect and cannot be objected to. In order to avoid colour irregularities, coloured render surfaces must be additionally painted with Sylitol® Finish 130 in the same colour as the render.

Suitable SubstratesReinforcement 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.
If necessary, cover the scaffold with tarpaulins to avoid exposure to rain during the drying phase. Carefully cover the area around the surface to be coated, especially glass, ceramics, paintwork, clinker, natural stone, metal, as well as natural or glazed wood. Immediately wash off any splashes of render with plenty of water.
The substrate must be plane, clean, dry, solid, load-bearing and free from separating substances. Observe VOB, Part C, DIN 18363, Para. 3. Clean surfaces affected by mould, moss or algae by means of pressure water jets, observing the legal regulations. Wash thoroughly with "Capatox" and allow the surfaces to dry thoroughly. Clean surfaces soiled by industrial fumes or soot by pressure water jetting with the addition of suitable cleaning products and in compliance with the legal regulations. To reduce the risk of staining with coloured finishing coats, ensure that the substrate is evenly dry!
Method of Application
Apply the wet mortar over the entire surface with a stainless steel trowel or a suitable fine render spraying machine and model, felt or slurry over the surface as desired when fresh.
The application thickness of the material is limited to a layer thickness between 2-5 mm.
The tool choice influences the roughness profile of the surface, therefore always work with the same tools.
To achieve a plane surface, connected areas should always be applied by the same craftsman to avoid differences due to different "handwriting".
To avoid lapping, use a sufficient number of workers on each scaffold layer. Work through wet in wet quickly.
In the case of creative structures, too great differences in material thickness should be avoided in order to prevent shrinkage cracks at the transitions.
It must be taken into account that in smoothed or washed-over structures a sintered layer can occur as a result of surface binder accumulation and fine shrinkage cracks cannot be completely ruled out. These do not represent a defect that can be objected to.
Due to the use of natural fillers and granulates, slight colour variations are possible. Therefore, only use material with the same batch number on connected surfaces or mix material with different batch numbers beforehand.
Surface Coating System
Priming or intermediate coats must be cured before any further application.
Capatect façade systems:
New mineral base coats ( reinforcement compounds).
No priming is required in the case of normal swift work. Prime weathered base coats with "PutzGrund 610" if left to stand for a longer period (e.g. winter break).
If new mineral base coat is used and work is carried out quickly, priming is not usually necessary.
Base coats of mortar groups PII and P III as well as mineral old renders and concrete:
New renders: Leave untreated for 2-4 weeks Prime with "PutzGrund 610"
Concrete, surface solid and load-bearing: Prime with "PutzGrund 610"
Render and concrete, surface rough porous slightly sanding, absorbent: Prime with "OptiSilan TiefGrund", intermediate coat with "PutzGrund 610".
Renders and concrete, highly absorbent, chalking surface: Prime with "Dupa-Putzfestiger", intermediate coat with "PutzGrund 610".
The consumption of the freely texturisable and fine-grained render is structure-dependent and variable.
Object-dependent or processing-related consumption must be determined.
During application and curing, 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. In this context, we 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).
New renders can usually be coated after a sufficient standing time of approx. 1 day/mm layer thickness. In unfavourable weather conditions, e.g. influenced by wind or rain, significantly longer curing times must be observed.
At +20 °C air and ambient temperature and 65 % relative humidity, reworkable after approx. 2-5 days.
An additional priming coat of "CapaGrund Universal" reduces the risk of lime efflorescence, so that the finishing coat can be applied after a standing time of only 7 days. The render dries by hydration and physically, i.e. by evaporation of water. Especially in the cool season and with high humidity, drying is therefore delayed.
Immediately after use with water.
"Capatect Modellier- und Spachtelputz 134" can be processed with all common flow mixers, spiral pumps and rendering machines, but can also be mixed manually with a powerful, slow-running agitator using clean, cold water to form a lump-free compound. Allow to mature and stir again briefly. If necessary, adjust the consistency with a little water after this maturing time.
Depending on the weather, the processing time is approx. 1 to 1.5 hours (pot life). In case of mechanical conveying, the maximum standing time in the hose is 30 minutes. Do not use water to make material that has already stiffened workable again.
Example for Machine Equipment
For machine processing, please request special information on processing with machine technology.
"Capatect Modellier- und Spachtelputz 134" provides the necessary protection against algae or fungal attack under normal conditions. If further preventive protection is desired, apply two coats of "ThermoSan NQG" facade paint.
Special Risks (Hazard Note) / Safety Advice (Status as at Date of Publication)
Causes skin irritation. Causes serious eye damage. May cause respiratory irritation. If medical advice is needed, have product container or label at hand. Keep out of reach of children. Do not breathe dusts or mists. Use only outdoors or in a well-ventilated area. Wear protective gloves/ eye protection. IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Immediately call a POISON CENTER/ doctor. Store locked up. Contains: Cement, portland, chemicals, calcium dihydroxide. Aqueous cement suspensions have an alkaline effect.
Additional advice: Wear long trousers. Avoid prolonged skin contact with the render. Immediately clean affected skin thoroughly with water. The longer fresh render remains on your skin, the greater the risk of serious skin damage. It is essential to follow the manufacturer's health and safety instructions during the application phase.
Only empty bags (without trickling) for recycling. be landfilled after concentration, when in compliance with local regulations.
