Surface preparation: The surface to be sealed must be firm, clean, dust- and grease-free. Remove all loose parts. The surface must be moistened before application.

Joint and cartridge preparation:

• Cut off the top of the cartridge and screw on the cartridge nozzle, which is then cut at an angle depending on the joint width. Insert the cartridge into the gun. If work is interrupted or the cartridge is replaced, release the lever of the caulking gun and retract the piston.
• Squeeze the material into the joint and smooth it immediately after application with a spatula or damp cloth. Remove excess material before it hardens.
• Curing takes 24 hours, after which the material should be heated slowly.
• As a result of the sealant's volume loss during curing, small cracks may appear on the surface. These can be removed by applying an additional layer, which bonds with the first layer.
• Clean application accessories immediately after use with water, as the hardened material is very difficult to remove.

Disposal: Only empty containers should be recycled. Material residues can be disposed of at a suitable landfill in accordance with local regulations.

Storage: Store for at least 12 months at +10°C to +25°C in unopened packaging in a dry place. Do not store near cold or hot objects.
