Troubleshooting
Sealant not dispensing
Ensure the sealant gun is properly loaded and the trigger is being pressed firmly. Check that the inner seal of the tube has been punctured and the nozzle is cut to an appropriate size.
Poor adhesion
Verify that the surfaces are clean, dry, and free from dust, grease, or other contaminants. Ensure the product has not exceeded its shelf life and was stored correctly.
Uneven bead application
Practice applying an even bead by maintaining consistent pressure on the sealant gun trigger and moving at a steady pace. Ensure the nozzle angle is consistent.
Sealant skinning too quickly
Work in smaller sections and apply the sealant promptly after opening the tube. Ensure minimal air exposure to the product before application.
