It must be specified by an LBP, able to provide a design memorandum to the relevant Building Consent Authority (BCA), if RBW provisions apply. Installation must be undertaken by or supervised by an LBP (carpentry license). If RBW provisions apply, this same LBP must complete the RBW memorandum.

Multistop 4 should not be exposed to sustained temperatures exceeding 42°C or to excessive, repetitive or continuous moisture before, during or after installation. All sources of moisture should be eliminated immediately.
