Substrates: all usual building substrates, metals, polyesters, … Nature: rigid, clean, dry, free of dust and grease.

Surface preparation: Soudaflex 42FX has a good adhesion to most substrates. However, for optimal adhesion and in critical applications, such as joints exposed to extreme weather conditions, high- or waterloaded joints, we recommend to follow a pretreatment procedure. Apply Primer 100 on porous substrates. Prepare non-porous surfaces with a Soudal activator or cleaner (see Technical Data Sheet).

There is no adhesion on PE, PP, PTFE (Teflon®) and bituminous substrates. We recommend a preliminary adhesion and compatibility test on every surface.
