The substrate must be stable, free from dust, loose parts and adhesives. New plaster and concrete must be bound and matured. Remove old, weakly adhering and peeling layers. Repair defects and unevenness in the substrate with special mortar. Reinforce porous, absorbent and weak substrates with a deep primer preparation. Cover expansion and construction joints, floor and wall connections with insulation tapes embedded in the foil.
