Different sealants for different pressure classes and applications.
Stop if
- Spec calls for sealant. Confirm mastic, UL tape, or gasket for this pressure class and application?
Watch out
- Don't use cloth duct tape. Don't use mastic as sole sealant on high-pressure. Don't guess based on last job.
Check
- Pressure class?
- Spec sealant type?
- Smoke or grease duct requirements?
