Storage of Sealant Compound that is not Mixed
(a)
Sealant that is not mixed and is kept for more than 6 months should be tested before you use it. A satisfactory check for outdated sealant is to mix a container of base material with its curing compound and, at room temperature, find the time necessary before a sample of the sealant you apply is not tacky. Compare this time with maximum permitted tack-free time given in the applicable sealant specification. If this time is more than the maximum permitted time, discard the sealant. You should keep sealant at temperatures between 50° to 80°F (10°C to 26.7°C).
