Instructions for use

Preparation of the substrate

Using a spatula, remove the residues of emulsion or oil paints and loose grains of sand. The surface should be clean, tight, and free of grease.


Highly absorbent substrates should be primed with CEKOL DL-80 emulsion. Prior applying of the finishing layer on the reinforcement layer in the ETICS systems, it is recommended to apply CEKOL GB-87 primer or CEKOL DL-80 deep penetrating primer.

Preparation of the mortar

Pour 1 kg powder to 0.16 – 0.20 litres of water and mix thoroughly.
