Installation Notes

This sealant is typically applied by general contractors, HVAC technicians, or plumbers working on penetration sealing, perimeter caulking, and gap filling tasks. Before application, surfaces must be clean, dry, and free of dust, oil, and loose material. Cut the nozzle tip to the desired bead size and apply with a standard caulk gun, tooling the bead immediately for full contact. Clean excess with water before the sealant skins over.
