Cut nozzle at 45° to desired bead size, insert in caulking gun and apply to desired area. Tool bead with moistened cloth and wipe off excess before it cures. For best results, tool immediately after applying for best adhesion and smooth finish before skinning occurs. Please see the technical specification for acceptable application temperatures and other technical information.

Clean Up

Remove Sealant off gun and all tools before it cures. Use typical solvents such as Mineral Spirits or lacquer thinner (ethyl acetate, acetone) and let dry to prevent any damage. Cured sealant can be removed with sharp tools, using caution.

Technology Limitations

It should not be subjected to continuous heat above 500°F and temporary heat above 600°F. It is not fireproof and will not withstand direct contact with a flame. It is not a waterproofing sealant but does require some atmospheric moisture for curing. It should not be applied in areas that are completely sealed off during the curing process. It should not be subjected to solvents. It may stain concrete, masonry, natural stone, or other sensitive materials. It shouldn’t be used on high traffic areas. It is not paintable.


Keep out of the reach of children. Wear safety glasses with side shields. Direct contact with eyes may cause slight to moderate irritation. In case of eye contact, flush thoroughly with water for at least 15 minutes. Seek immediate medical attention. In case of skin contact, wash affected areas with soap and water.
