Application
Suitable for repairing and sealing cracks, seams and joints in fireplaces, multi-burners, stoves, chimneys and assembling and sealing concrete fireplaces and barbecues. Also suitable for temporary sealing of car and motorcycle exhaust systems. Bonds to metal, stone and concrete.
Not suitable for central heating systems and gas pipes.
Handling
Before use
Only apply at temperatures between +5 °C and +40 °C.
The surface must be clean and free of dust, rust and grease.
Degrease metal parts with degreaser or acetone. For application to porous substrates, slightly moisten the substrate with water.
Apply cartridge with GRIFFON cartridge gun and use GRIFFON Multi Tool to open the cartridge and tooling the sealant.
Content suitable for approx. 9 m (depending on the diameter of the joint).
During use
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.
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 (cover from rain showers in outside use). 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.
Once fired up, the sealant may colour slightly lighter (depending on temperature). The sealant can only withstand 1250°C until it is fully cured. Always test the adhesion before application. Do not use on permanently wet areas. 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.
After use
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.
