Permanently set threaded rods, studs, and rebar in dry concrete with these two-part epoxies. They form a weather-resistant chemical bond that seals out moisture and resists vibration and dynamic loads better than mechanical anchors. The size listed is the combined total of the two parts. Warning: Allowable pull-out strength is 25% of ultimate values or less, as required by building authorities.

Adhesives in cartridges can also be used in damp concrete. Use a mixer nozzle and dispensing gun (dispensing gun sold separately) to simultaneously mix and dispense adhesive.

Adhesives in pails have epoxy and hardener in separate containers that can be mixed in the pail.

Patch concrete floors and stairs with these compounds.

Mix gypsum compounds with water. They can also be used to anchor bolts, railings, and posts. When used outdoors, apply a sealer (not included) for best results.
