Tips

For best results, clean and dry all surfaces before application. Cut the nozzle at a 45° angle to the desired bead size and apply steadily. Smooth the bead with a spatula or finger dipped in soapy water within 5 minutes. Allow at least 24 hours for full cure before exposing to water. Store unused cartridges in a cool, dry place.
