Clean all surfaces. Joint walls must be sound, clean, dry,
frost-free, and free of oil and grease. Curing compound
residues and any other foreign matter must be
thoroughly removed. A roughened surface will also
enhance bond. Place nozzle of gun into bottom of the
joint and fill entire joint. Keep the nozzle in the sealant; continue on with a steady flow of sealant preceding the nozzle to avoid air entrapment. Avoid overlapping of sealant to eliminate entrapment of air. Heavier substrates may require additional support
during the cure period.For more information, consult TDS.
