Field of Application
Mineral lightweight render according to DIN EN 998-1 in the Capatect facade 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 subject to extremely high mechanical loads.
Material Properties
- Smooth and easy processing due to lightweight supplements
- Highly permeable to water vapour

The consumption data are approximate values without bulk and shrinkage loss. Object-dependent or processing-related deviations must be taken into account.
Substrate Preparation
The substrate must be even, clean, dry, solid, load-bearing and free from separating substances.
Clean surfaces affected by mould, moss or algae using pressurised water jets, observing the legal regulations. Wash with Capatox and allow the surfaces to dry thoroughly.
Clean surfaces soiled by industrial fumes or soot using pressure water jets with the addition of suitable cleaning agents and in compliance with the legal regulations.
Germany: Observe VOB, Part C, DIN 18 363, Para. 3.
All substrates, especially basecoats, must be evenly dry to avoid colour deviations in the finishing plaster.
Method of Application
Apply the wet mortar over the entire surface with a stainless steel trowel or with a fine plaster spraying machine and rub down to grain size. Immediately afterwards, rub down evenly round with a PU or wooden board, a foam rubber disc or with a plastic rubbing board, texture the rubbing plasters horizontally, vertically or round as desired.
The choice of tool influences the roughness profile of the surface, therefore always work with identical structure discs. To achieve a uniform texture, contiguous surfaces should always be finished by the same craftsman to avoid texture deviations due to different "handwritings". To avoid build-up, use a sufficient number of workers on each scaffold layer. Work through wet in wet quickly.
Due to the use of natural fillers and granulates, slight colour variations are possible. Therefore, only use material with the same product number on continuous surfaces or mix material with different product numbers beforehand.
Capatect Mineral-Leichtputze is not suitable for horizontal surfaces exposed to water.
Surface Coating System
Primer or intermediate coats must be dry before further recoating.
Capatect Facade Systems:
New mineral base coats (reinforcing compounds):
No priming required in case of normal rapid working.
In case of longer standing time (e.g. wintering), weathered basecoats require a priming coat of "PutzGrund 610".
"Capatect Klebe- und Armierungsmasse 133 Leicht" and "Capatect Klebe- und Armierungsmasse 186M" must be primed with "Sylitol® RapidGrund 111" diluted, if necessary (depending on weather and absorption behaviour).
Capatect interior insulation systems:
If new mineral reinforcement is used and work is carried out quickly, priming is not usually necessary.
Basecoats of mortar groups PII and PIII, as well as old mineral renders and concrete:
New base coats, unless otherwise specified:
Leave untreated for 2 - 4 weeks, prime with "PutzGrund 610".
Concrete, surface firm and load-bearing:
Prime with "PutzGrund 610"
Render and concrete, surface coarsely porous, slightly sandy, absorbent:
Prime coat with "OptiSilan Tiefgrund", intermediate coat with "PutzGrund 610".
Render and concrete, highly absorbent, chalky surface:
Prime with "Dupa-Putzfestiger", intermediate coat with "PutzGrund 610".
Application Conditions
During the application and 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. Protect fresh plaster from rain and rapid drying.
In this context, we refer to the leaflet "Verputzen, Wärmedämmen, Spachteln, Beschichten bei hohen und tiefen Temperaturen" from the "Bundesverband Ausbau und Fassade".
Drying/Drying Time
approx. 2 - 5 days, coatable after sufficient standing time, usually after 2 weeks at approx. 20 °C and 65 % rel. humidity.
The plaster/ render dries by hydration and physically, i.e. by evaporation of the mixing water and depends on the application quantity. In unfavourable weather conditions, e.g. influenced by wind or rain, significantly longer standing times must be observed. An additional priming coat of "CapaGrund Universal" reduces the risk of lime efflorescence, so that the finishing render can be coated after a standing time of only 7 days.
Tool Cleaning
Immediately after use with water.
Material Preparation
"Capatect Mineral-Leichtputz" can be applied with all common continuous mixers, screw feed pumps and plastering machines, but can also be mixed manually with a powerful, slow-running agitator using clean, cold water to a lump-free mass, allowed to mature and stirred again briefly. If necessary, adjust the consistency with a little water after this maturing time.
Scratch texture:
1.0 mm 25 kg material (one bag) in approx. 6.5 l water.
1.5 mm 25 kg material (one bag) in approx. 6.5 l water
2.0 mm 25 kg material (one bag) in approx. 7.0 l water
3.0 mm 25 kg material (one bag) in approx. 7.5 l water
4.0 mm 25 kg material (one bag) in approx. 7.0 l water
5.0 mm 25 kg material (one bag) in approx. 7.0 l water
Rub texture:
3.0 mm 25 kg material (one bag) in approx. 7.0 l water
5.0 mm 25 kg material (one bag) in approx. 6.5 l water
Depending on the weather, the working time is approx. 1 to 1.5 hours (pot life), with machine delivery the max. 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.
Special Risks (Hazard Note) / Safety Advice (Status as at Date of Publication)
Causes skin irritation. Causes serious eye damage. If medical advice is needed, have product container or label at hand. Keep out of reach of children. Do not breathe dusts or mists. Wash skin thoroughly after handling. 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. 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.
Disposal
Only empty bags (without trickling) for recycling. Can be landfilled after concentration, when in compliance with local regulations.
