Troubleshooting
Sealant not dispensing from the tube
Ensure the nozzle has been cut correctly and that the inner seal has been pierced. Check that the sealant gun is functioning properly.
Poor adhesion to the surface
Verify that the surface was clean, dry, and free from contaminants before application. Ensure the correct application technique was used and that the sealant has been allowed sufficient curing time.
Uneven bead application
Practice applying with a sealant gun on a scrap surface to achieve a consistent pressure and movement speed. Ensure the nozzle opening is the appropriate size for the gap being filled.
Sealant remains tacky after application
This could be due to excessive application thickness or insufficient ventilation. Ensure adequate airflow around the application area. Thicker applications may require longer curing times.
