Inspection & Repair
RectorSeal recommends that a firestop system inspection be conducted during
installation of the material in accordance with ASTM E2174 and ASTM E2393. In the
event post-installation inspection and destructive sampling is necessary, RectorSeal
advises repairing the damaged firestop system by replacing any material that was
removed or damaged with the same product originally installed, and ensuring
the assembly matches the original firestop listing. RectorSeal advises, that due to
the chemical nature of firestop products and sealants, material depth should be
determined by measuring the points of adhesion at the substrate bond area as
sealants may decrease in size during the curing process.
Storage & Handling
Metacaulk 150+ should be stored between 35˚F (2˚C) and 120˚F (49˚ C) to obtain a 3 year
shelf life.
NOTE: Do not dilute, no mixing is required. Best if protected from freezing. If freezing
