Directions for use
Slightly moisten the joint with water before applying. Inject the sealant evenly into the joint and tool immediately with a wet putty knife. Allow to dry for at least 24 hours. Then heat gently until the sealant has cured. For exhaust systems, first apply a layer of sealant, press in a piece of fiberglass cloth and cover it again with sealant. Allow to dry for at least 24 hours. Remove excess sealant immediately with water.
Points of attention
Thermal loading of the sealant when it is not yet entirely cured may result in the forming of tears and even to crumbling of the sealant. After some time, a liquid film will form on the sealant, but this has no effect on the quality of the sealant. Usage in electrical equipment can be hazardous with regard to the conductivity of the product.
Remove wet stains immediately with water. Cured residue can only be removed mechanically.
Store in properly sealed packaging in a dry place at between +5 °C and +25 °C.
