Histolith Trass-Vorspritzputz

Hydraulic spray render mortar for exterior and interior use
LV Texte

Field of Application

Suitable as a bonding bridge on masonry in the Histolith® Trass-Sanierputzsystems in exterior and interior areas. Partial component of the Histolith® Trass-Sanierputzsystems.

The structure and layer thickness of the Histolith® Trass-Sanierputzsystem depend on the salt load present in the masonry in accordance with WTA data sheet 2-9-20/D. The Histolith® Trass-Sanierputzsystem is suitable for plastering damp and salt-contaminated masonry. Due to the large pore volume, building-damaging salts are trapped. In this way, an efflorescence-free and dry surface can be achieved on damp masonry if the surrounding climate allows it to dry out.

Suitable Substrates

Damp and salt-contaminated masonry on interior and exterior surfaces.

Application limits:
The Histolith® Trass-Sanierputzsystem is not suitable for waterproofing building components in contact with the ground against pressurised water, backwater and ground moisture. In these cases, suitable sealing measures must be carried out beforehand. This also applies to very high levels of masonry moisture penetration due to rising damp. There must be no direct contact with soil or cladding in the plinth area.

The Histolith® Trass-Sanierputzsystem cannot prevent damage caused by frequent falls below the dew point.

Preparatory work

Mask window sills and add-on parts.
Carefully cover glass, ceramic, clinker, natural stone, painted, glazed and anodised surfaces.

Substrate Preparation

Remove damaged render at least 80 cm above the recognisable edge of the damage. Any old render
containing salt must be removed immediately.Remove crumbly parts, dirt, dust, old bitumen coatings and other substances with a separating effect.

Expose damaged masonry joints to a depth of at least 20 mm.
Thoroughly clean the masonry mechanically. The substrate must be load-bearing.
Pre-wet highly absorbent masonry (matt damp).

VOB Part C, DIN 18350 must be observed.

Preparation of Material

30 kg of material (one bag) in approx. 7 litres of water.

The material can be mixed with a powerful, slow-running agitator or compulsory mixer with
mixer and with clean, cold water to form a lump-free mass.
Work through again after approx. 3-5 minutes. If necessary, adjust the consistency with a little water after this maturing time.

Depending on the weather, the working time is approx. 2 hours (pot life).
Do not use water to make material that has already hardened workable again.

Method of Application

Apply the material with a trowel in a half-covering, wart-shaped pattern in approx. 1 - 2 grain thicknesses. The joints must not be completely filled with spray filler.

Layer Thickness

2-5 mm

Surface Coating System

  • low salt load: Histolith® Trass-Vorspritzputz + Histolith® Trass-Sanierputz single layer
  • medium salt load: Histolith® Trass-Vorspritzputz + Histolith® Trass-Sanierputz multi-layered
  • high salt load: Histolith® Trass-Vorspritzputz + Histolith® Trass-Porengrundputz + Histolith® Trass-Sanierputz 

Histolith® Feinputz can also be applied to the system structures. With a total render thickness of more than 30 mm, Histolith® Trass-PorenGrundputz must always be used as a base render to level the masonry.

A coating is required for exterior areas. Coating only with highly Water vapour permeable paints,
Histolith® Dispersionssilikatfarben and Histolith® Kalkfarben are recommended. Additional pretreatment with Histolith® Fluat reduces the risk of lime efflorescence.

Consumption

  • approx. 5,0 kg/m2

These consumption figures are approximate values.
Deviations depending on the property or processing must be taken into account.

Weather 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. 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).



In unfavourable weather conditions, suitable measures must be taken to protect the facade surfaces.

Drying/Drying Time

The waiting time for reworking depends on temperature, humidity, air movement, sunlight and
application thickness. The information is therefore intended as a guide.

The following waiting times must be observed before applying the next layer:

  • Histolith® Trass-Vorspritzputz: at least 1 day until light drying
  • Histolith® Trass-Porengrundputz: Standard value 1 day per mm layer thickness
  • Histolith® Trass-Sanierputz: single layer: 3-7 days, double layer: first layer 1-4 days, second layer 3-7 days
  • Top coat on Histolith® Trass-Sanierputz: day per mm layer thickness as a guide (especially forlayer thicknesses over 20 mm)
  • Histolith® Feinputz: can be painted over after 7 days

Protect the treated surfaces from drying out quickly during the drying period.
If necessary, keep surfaces moist by wetting them carefully.

Tool Cleaning

Rinse with water immediately after use in accordance with legal requirements.
