Suitable Substrates

Primed windows and doors as well as primed unplasticized (rigid) PVC and sound existing paints.
The substrate must be clean, sound/stable, dry, and free from all substances that may prevent good adhesion. Maximum permissible wood moisture in dimensionally stable wood: 13 %.

Substrate Preparation

Wooden Parts:
Sand the surface in fibre direction, clean thoroughly, then remove seeping wood contents, e.g. resin/rosin and resin/pitch pockets, cut sharp edges (see BFS Data Sheet No. 18).

Unplasticized (Rigid) PVC:
Wash with light ammonia solution using sanding pad according to BFS Data Sheet No. 5 and No. 22.

Sound Existing Paint Coatings:
Sand the surface of existing paint coatings slightly and/or treat with alkali. Remove unsound coatings.
