Waterproof seal
Multitude of Industrial uses
As a gasket sealant.
For joints and assemblies, which must be resistant to high temperatures in ducting, metal chimneys, industrial/domestic ovens, heating appliances.

Do not use above 300˚C

Do not use on porous surfaces such as brick, concrete and stone.
Do not use in conjunction with bitumen, lead or Asphalt.
Not for use on substrates that may bleed oils, solvent or plasticisers.
Do not use on soft metals such as lead or brass.
On temperatures above 285˚C, slight discolouration may occur, but the joint will maintain its integrity.
Do not use above 300˚C

All surfaces must be clean, dry and dust free. All loose or flaking surface coatings, and old sealant and mastic joints, should be removed before application. Highly porous substrates such as new plaster should first be primed with a dilution of Caulk with water at a ratio of 1:2. Can be applied to slightly damp surfaces.
