Getting started

Before use:

Working conditions

Only apply at temperatures between +5°C and +40°C.

Surface requirements

The surface must be dry, clean and free of dust, rust, paint and grease.

Preliminary surface treatment

Degrease metal parts with Bison Degreaser or acetone. For application to porous substrates, slightly moisten the substrate with water.


Apply cartridge with a Power Pistol. Multi Tool to open the cartridge and tooling the sealant.

During use:

Handling of packaging

Use sealant gun to handle cartridge. Open the cartridge by cutting off the plastic nipple on the top side at the screw thread with a sharp knife. Screw on the nozzle and chamfer at the desired width.

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.

After use:


Remove wet stains immediately with water. Cured residue can only be removed mechanically.

Storage conditions

Store in properly sealed packaging in a dry place at between +5°C and +25°C.
