Troubleshooting
Sealant not dispensing or dispensing slowly
Ensure the nozzle is cut appropriately and the tube is punctured correctly. Check if the sealant has started to cure inside the nozzle or tube. Try using a high-quality sealant gun with sufficient leverage.
Poor adhesion to surfaces
Verify that the surfaces were thoroughly cleaned, dried, and free from any contaminants like dust, oil, or old sealant. Ensure proper surface preparation, including light abrasion if necessary for non-porous materials.
Sealant not fully curing or remaining tacky
This could be due to low temperatures, high humidity, or applying too thick a bead. Ensure application is within the recommended temperature range and allow adequate curing time in appropriate conditions. Avoid disturbing the seal during the curing process.
Uneven or messy bead application
Practice applying on a scrap surface. Use masking tape to create clean edges before application and remove it immediately after the bead is laid and tooled. Ensure consistent pressure on the sealant gun.
