Can you use Blu Tack on wood?
Whether or not Blu Tack can be used on wood, depends on the finish of the wood. Bostik recommends Blu Tack for non-porous surfaces, so it may not be suitable for unfinished or absorbent wood. If you’re unsure, test it on a small, hidden area first, as Blu Tack can sometimes leave an oily mark on certain surfaces.
