Air means life

Tension-free reinforcing mortar

Stabilise the entire plaster structure of the aerodurit® PHOENIX lime thermal insulation plaster in a reliable and long-lasting way by using aerodurit® IMMORTAL air-lime reinforcing plaster. This reinforcing mortar for lime thermal insulation systems was specially designed for the repair of facades and interior walls in listed buildings.

Why reinforcing mortar?

Due to the embedded reinforcement fabric, the reinforcement mortar connects different substrates with different expansion behaviour and thus increases the surface’s resistance to cracks. Give your precious aerodurit® PHOENIX thermal insulation plaster an effective protective shield: with aerodurit® IMMORTAL air lime reinforcing plaster you make it (almost) immortal!
