Bonstone Fast Set Extreme

Description

Bonstone Fast Set Extreme is a fast-setting cold weather epoxy formulated for jobs where temperature or schedule will not allow a standard-cure adhesive to work. It cures in below-freezing conditions and bonds to slightly damp stone, which makes it a practical choice for outdoor structural repairs when waiting for warmer, drier weather is not an option.

When this cold weather epoxy is the right call

Most two-part epoxies slow down dramatically as ambient temperature drops, and some will not cure at all near or below freezing. This product is built specifically to keep working in those conditions, so crews doing anchoring, crack repair, or structural bonding outdoors in winter are not stuck waiting for a heat source or a warm spell. It is intended for exterior use only and is not recommended indoors, where slower-curing formulas typically perform better anyway.
