Leak Sealing Paste

Dammit paste application onto leaking drum

The clay plugging compound is specifically developed for the emergency sealing of leaks from holes, tears and ruptures. It provides an instant seal on drums and tanks to stop liquids including chemicals and oils leaking out of the container.

The paste is clay compound that when moulded into a ball and placed over the tear or hole in the drum, instantly seals the hole and stop the spread of pollutants. By preventing the container from completely emptying, it gives the opportunity to transfer the remaining contents into another container. We recommend paste is included in most spill kits.
