The substrate must be dry, free of dust, oil, wax, grease, dirt, resin, etc.
Existing coatings or coatings with poor adhesion must be completely removed, e.g. with solvent-based paint strippers or sanding.
Surfaces that have been treated with non-acid-resistant coatings, such as emulsion paints containing lithopones, lime or chalk, must be completely removed by sanding.
If there is limited penetration into the surface, roughen the adhesion with sandpaper. The moisture content of the wood should not exceed 12%.
