Using tape alone where mastic/spec requires more

If the spec or foreman calls for mastic/fabric/listed product, tape alone is not a substitute.

Stop if

• This joint was taped, but I think the spec calls for mastic or another seal method. Do you want it corrected before cover/test?

Watch out

• Do not assume tape alone passes because it looks neat.

Check

• Ask what method applies to that system.
• Check label/listing on the tape or sealant.
• Remove wrong material if directed.
• Apply approved method to the cleaned joint.
• Document if wrong material was already used by another crew.

Steps
