Cocoon, available from Cocoon Coatings , is a spray-on membrane that seals permanently. Once applied, Cocoon creates a flexible surface area that is far more durable than the traditional quick-fix layer of silicon used by many maintenance crews.

With a wide range of applications, Cocoon has been successfully used on surfaces as diverse as: roofing (box-gutters), silos, marine, swimming pools, water features and specialised hygienic projects for hospitals.
