The surface to be covered must be dry and free from dust, grease, and other contaminants before installation, as these can affect the adhesive strength of the material.
For newly painted or varnished surfaces, ensure that the paint is completely dry and cured. Before cleaning, also check whether the cleaning agent used discolors or damages the surface.
Especially for walls, vehicles, and boats, the following conditions apply:
- Smooth, even surface (no textured wallpaper or heavily structured surfaces)
- Dust-free
- Grease-free
- No loose particles (e.g., paint, color, or plaster residues)
- No latex-based paints
- Not painted or varnished within the last 4 weeks
- No low-energy surfaces
- Do not use solvent-based cleaners that attack or remove adhesive residues
