Substrate Preparation

All substrates must be level, cured, undamaged, compact, rigid, resistant, dry and free from any debonding agents and from damp rising. It is good practice to dampen highly absorbent concrete substrates or apply a coat of Primer A Eco.


To guarantee maximum adhesion it is necessary to apply a layer of adhesive sufficient to cover the entire back of the coating material. Large, rectangular sizes with sides > 60 cm and low thickness sheets may require adhesive to be applied directly to the back of the material. Check samples to make sure the adhesive has been transferred to the back of the material.

Create elastic expansion joints:

– ≈ 10 m2 in external applications,
– ≈ 25 m2 in internal applications,
– every 8 metres in long, narrow applications.

Respect all structural, fractionizing and perimeter joints present in the substrates.
