What do I do when sealant cracking because joint moves/stressed?

Sealing, Leakage, Mastic & Pressure Testing.1 field-polished — seal/test detail check

Sealant cracking usually means the joint is moving, stressed, dirty, or unsupported. Fix the cause before resealing.

Field checklist

This sealant is cracking because the joint looks stressed. Do you want the support/fit fixed before resealing?

Do not keep adding sealant to a joint that is still moving.

A moving joint will keep breaking the seal until the support or fit-up problem is corrected.
