Sealant mixing is carried out IAW?

• A. Manufacturer instructions.
• B. Company policy.
• C. Customer preferences.
• D. Regulatory guidelines only.

Answer: (A)

Sealant mixing must follow the manufacturer's instructions. The manufacturer provides the exact mixing ratio, pot life, temperature range, surface prep, and any activators or primers required to ensure the sealant cures correctly and bonds reliably. Deviating from these directions can lead to improper curing, reduced adhesion, or leaks, compromising structural integrity and safety.

Company policy often supports or reinforces the manufacturer’s procedure, but it isn’t the primary source of the technical steps. Customer preferences have no bearing on how a sealant is prepared, and regulatory guidelines alone don’t specify the exact mixing procedure the product requires.
