Bonstone Fast Set Extreme Cold Weather Epoxy, 250ml

Description

Bonstone Fast Set Extreme is a fast-setting, cold-weather epoxy for exterior structural work where ordinary epoxies set too slowly or refuse to cure at all. It is formulated to cure in below-freezing temperatures and will adhere to stone that is slightly damp, two conditions that stop most general-purpose epoxies from working on a job site. The manufacturer recommends this product for exterior use only, not interior repairs.

Bonstone Fast Set Extreme Applications

Typical uses include structural bonding and repair of natural stone, concrete, masonry, metal, and wood; re-attaching stone that has come loose from a facade, cap, or veneer; anchoring bolts, dowels, rebar, and pins into stone or concrete; and general crack repair on porous exterior surfaces. Because it tolerates porous, slightly damp stone, crews can move faster on outdoor jobs without waiting for a substrate to dry completely, which matters most on repair calls scheduled around weather rather than a controlled shop environment.

Bonstone Fast Set Extreme Handling and Ordering

The 250ml package is a 1:1 ratio, buff-colored epoxy dispensed from a single-cartridge gun through a large Pro-Tip 280AN226 static mixing nozzle, with a cure time of about 2 hours once mixed. It weighs roughly 1 lb and measures about 2 x 2 x 7 in, sized for job-site anchoring and repair work rather than large-batch shop use. Cold weather set speed comes from the formulation itself, not from heating the material, so it performs the same in a truck bed on a winter job as it would in a warmer shop. For larger jobs, The same Fast Set Extreme formulation is also packaged in quart kits, gallon kits, and 5-gallon pail kits, so a fabricator can scale from a single anchor repair up to a full crew’s daily supply without switching products.
