Questions about this item
What does ASTM C920 Class 25 mean for joint movement once the sealant is in place?
It certifies the sealant can handle up to 25 percent joint expansion or contraction without losing adhesion or cracking.
How does the cartridge format affect the tools I need to apply it?
The 10 oz cartridge fits a standard caulking gun, so no special dispensing equipment is required.
What surface preparation or backing is needed for the sealant to bond properly?
Clean, dry, and frost-free surfaces are required; use a backer rod in joints deeper than 1/2 inch to control depth and ensure proper cure.
