Condition / Tests
The substrate must be dry, stable, absorbent and free of dust, formwork oil or other separating agents.
To assess the substrate, the instructions in VOB Part C, DIN 18350 and DIN 18550 must be observed.
Remove loose parts, dust and dirt that could prevent adhesion.
Pre-wet highly absorbent substrates.
Smooth surfaces must be pre-treated with a bonding agent before the frames are attached.
Do not apply and allow to dry / set at air, material and substrate temperatures below +5 °C and when night frost is to be expected and above +30 °C, direct sunlight , strongly heated substrates and/or strong winds.
Mixing / preparing / processing
The mortar is mixed with conventional mixing pumps, e.g. B. PFT G4 introduced.
Set the water supply to a consistency suitable for processing.
The consistency should be adjusted so that the cavities between the frame and the wall reveal are filled without any cavities.
Application / processing
The mortar is to be introduced in sections, alternately while lightly tapping on the frame at the same time. The hose opening should be in the fresh mortar in order to ensure mortaring with few cavities.
Basically, work fresh on fresh.
drying / hardening
The struts must not be dismantled before they have hardened.
Clean tools and equipment with water immediately after use.
The frames must be professionally assembled and anchored before backfilling. The steel frame is to be expanded in such a way that any profile deflections that are to be expected as a result of backfilling are absorbed.
consumption / yield
Yield: approx. 16 l wet mortar per sack
Approx. 18 kg of dry mortar K 01.5 are required for an average filling volume of 20 mm in height, 11.5 cm in width and 5 m in length.
