How much weight can Blu Tack® hold?
Bostik Blu Tack® does not have a single weight limit that applies to every situation. Its holding performance depends on factors such as the surface type, surface condition, the size and weight of the item, and the amount of Blu Tack® used.
For the best results, use Bostik Blu Tack® on suitable clean surfaces and test it with the item you intend to display before relying on it for long-term mounting.
