• Apply the Sealant — Shake the can well. Spray evenly from 8 to 12 inches away, holding the can upright. Apply multiple thin coats, allowing adequate cure time (typically 15-30 minutes) between each coat.
• Cure and Test — Allow the sealant to fully cure for at least 24 hours before exposing it to water or paint. Perform a light water test to ensure all gaps are sealed; apply additional coats if needed.
• Clean Up — To prevent nozzle clogging, turn the can upside down after use and spray a short burst of clear gas onto a disposable object until only gas comes out.
