Pebeo Gedeo is a natural clay that hardens without cracking or firing in 4 - 5 days. It's ready to use straight out of the packet and is formulated with a synthetic binder that enables it to harden naturally. After treatment with a waterproofing agent it can be used to produce waterproof containers for non-alimentary use.
Instructions for use: Model or apply to an object or in a mould to take the imprint. Hardens in air, without firing. Sand, glue or paint and varnish after complete drying (4 to 5 days). Place near a source of heat to accelerate drying. To create watertight containers use a waterproofing agent. Keep the clay and any current work protected from the air in a damp plastic bag.
