Application tips
Ensure the surface is clean, dry and dust-free before applying the tape. The particularly conformable Washi backing allows the tape to adapt perfectly to irregular surfaces such as light render. Press the edges down carefully to guarantee sharp and precise paint lines.
Thanks to its exceptional hold for up to 26 weeks, you can plan your work in multiple phases without needing to remove and reapply the tape between coatings. Removal is effortless and leaves no residue, even after prolonged exposure to Belgian weather conditions. For optimal results, remove the tape at a 45-degree angle whilst the paint is still slightly damp.
Available in five widths (19, 25, 30, 38 and 50 mm), the tesa® 4440 adapts to all your masking needs, from fine lines to large protective areas.

Pro tips
At Pygmalion, we recommend the tesa® 4440 for all your exterior projects requiring long-lasting performance: facade renovations, external carpentry work, or projects with planned interruptions. Its hand-tearability saves valuable time on large jobsites whilst maintaining precision edge lines. For Belgian projects exposed to harsh weather, its 26-week UV resistance offers unparalleled security, even during prolonged rainy periods.
Pro tip: for perfect angles, slightly overlap the tape strips by crossing the ends, then make a sharp cut with a utility knife through both layers. This creates invisible joints, even on complex trim work.
