Remove old film
The paint scraper with 50 mm blade and 2K soft grip lifts loose, weathered film and paint residue off the profile. A matching replacement blade is available for blunt blades.
With the right tools, repair film sticks perfectly the first time: a paint scraper to remove old film, isopropanol to degrease unfoiled frames, a squeegee to press the film on without bubbles and sharp utility knives for clean edges. Plus window frame cleaners for foiled uPVC windows and colour fans from RENOLIT and Continental to identify the decor.
A self-adhesive window frame foil only holds as well as the surface it sits on. There is a suitable tool for every step – matched to the films from RENOLIT and Continental.
The paint scraper with 50 mm blade and 2K soft grip lifts loose, weathered film and paint residue off the profile. A matching replacement blade is available for blunt blades.
Degrease unfoiled frames with isopropanol 99.9 % – ideal when white uPVC windows are wrapped in a decor for the first time. Clean existing window frame foil with the window frame cleaner. The adhesive only reaches full bond on a clean, dry surface.
Use the squeegee to smooth the film from the centre outwards onto the profile contour. The felt edge glides over the decor surface without scratching it.
Cut off excess film at the glazing bead, seal and mitre with the utility knife. For a clean cut, snap off or change the blade in good time.

Foiled window frames do not tolerate harsh all-purpose cleaners or scouring agents – solvent-based products can attack the decor surface and make it dull. Our window frame cleaners are suitable for rigid PVC profile surfaces and for PVC film laminations from RENOLIT and Continental.
They gently remove dirt, adhesive residue and the white streaks that are often left on the frame after installing new windows. The RENOLIT EXOFOL care set is available for regular care. You will find more tips in our guide Cleaning window frames.
A film squeegee presses window frame foil on evenly and pushes air out to the side. Which squeegee suits you better depends on the profile and how you work.
Plastic squeegee with a felt edge: rigid enough for firm pressure on straight surfaces, while the felt side protects the decor surface. The right choice for most window profiles.
Made entirely of felt and therefore slightly more flexible. Ideal for rounded profile edges and delicate matt surfaces where every pressure mark would show.
A colour fan lets you match the decor directly at the window – colour, wood grain, gloss level and embossing. This is especially worthwhile if you are wrapping several windows, front doors or entire facade elements, or want to change the colour.
If you only want to check one specific decor, a single film sample for €0.99 is the cheaper option.
At least a squeegee to press the film on, a sharp utility knife and a suitable cleaning agent: isopropanol for unfoiled white frames, the window frame cleaner for surfaces that are already foiled. If loose old film has to come off, you also need a paint scraper.
With a cleaner that is suitable for PVC film laminations and does not attack the surface. Scouring agents, cellulose thinners and solvent-based all-purpose cleaners are unsuitable for foiled window frames.
Grease, silicone and cleaner residue prevent the film's adhesive from bonding fully. The film then comes loose at edges and corners first. On unfoiled uPVC frames, isopropanol 99.9 % evaporates without residue and leaves a clean bonding surface. If you are applying film over existing window frame foil, clean it with the window frame cleaner – prolonged exposure to isopropanol can damage the film.
Lift loose and cracked film flat with the paint scraper without cutting into the profile. Firmly bonded, intact film can stay if the surface is flat – a pronounced grain texture should be smoothed beforehand.
A colour fan shows all decors of a collection at a glance. This lets you identify the existing film on your window or choose a new decor. For individual decors, a film sample for €0.99 is enough.
