How do you get Blu Tack® off wallpaper?
To remove Bostik Blu Tack® from wallpaper, carefully lift or roll the adhesive away from the surface rather than pulling it off quickly.
Wallpaper types and finishes can respond differently to adhesive removal, so work slowly and test your approach in a less visible area first. For step-by-step removal instructions and guidance on dealing with marks, see the How to Remove Blu Tack® Stains from Walls tutorial.
