Instruction for use

Preparation of the substrate

The substrate should be clean, tight, free of grease. Oil paints, glue colours and loose grains of sand must be removed.


Highly absorbent substrates should be primed with a deep penetrating primer CEKOL DL-80.

Preparation of the mortar

The mortar should be prepared by pouring 1 kg of powder to about 0.4 litres of water and mixing it thoroughly. The plaster finishing prepared in such a way can be used within two weeks provided that it is stored in a sealed container.


The product should be applied to the surface using a smooth stainless steel float. The thickness of applied layer should be max. 3mm. Usage: approx. 1.5 kg/m2/mm. Working temperature: +5 ÷ +30˚C. Another layer should be applied after the complete hardening and drying of the first layer.

Further work

After the initial hardening, it is possible to make adjustments using a sanding screen or sandpaper. Painting or wallpapering can be started when the surface is fully dry.
