Troubleshooting

Sealant is not adhering to the surface.

Ensure the surface is clean, dry, and free of any contaminants. Roughen smooth surfaces for better adhesion.

Sealant is cracking after application.

Ensure the sealant is applied in the correct bead size and allow sufficient time for curing before exposing it to high temperatures. Make sure the joint can accommodate movement.
