The sustainable material from the can

KALKOpor from the can is used for the production of KALKOpor damp masonry plaster

as a construction site mix. On the construction site, the powdery KALKOpor

from the can is added to the sand-lime mixture.

1 can in combination with sand, lime and water yields approx. 78 litres of wet mortar. With an application thickness of 20mm, the material is sufficient for approx. 4m².

Before starting plastering work, wash/wet the complete wall surface of the day's work with a deep-acting hose
(hose without nozzle). In windy and sunny conditions, rewet already plastered surfaces as required
and/or shade them, otherwise there is a risk of burning. Before leaving the construction site, re-wet the plastered surfaces
if necessary.


approx.10 litres of clean tap water (binder NHL lime), binder slaked lime first without adding water.

60 litres of washed sand
1 can of KALKOpor and

Add 20 litres of binder to the mixer.


The masonry must be sufficiently pre-wetted before applying the adhesive spray and after each coat of plaster.

Precoat/adhesive coat: Apply with a trowel to cover the entire surface (up to 5 mm thick), leaving the surface rough.
Coarse plaster/base plaster/plaster layer mortar: Minimum application thickness 20mm.
For levelling and plastering, only remove the mortar (aluminium/wood lath), do not rub and leave the surface rough.
For greater thicknesses, apply the mortar in even layers of 20mm.


The minimum interval between
The minimum interval between working cycles should be at least 24 hours, or longer if site conditions are unfavourable. Before each layer of plaster, pre-wet again as described above.

KALKOpor is an additive
