What removes Blu Tack® from wallpaper?
If Bostik Blu Tack® is stuck to wallpaper, carefully roll the adhesive away from the surface rather than pulling it off suddenly. This can help minimise the risk of damaging delicate wall coverings.
If a mark remains after removal, see the Malaysia guide How to Remove Blu Tack® Stains from Walls for step-by-step advice on dealing with Blu Tack® residue and wall marks.
