Dayton Superior Pro-Poxy 204 is a fast-setting, medium-viscosity, 1:1 epoxy for bonding fresh concrete to hardened concrete. Case of 12 x 600 ml.
Dayton Superior Pro-Poxy 204 is a 100% solids, fast-setting, two-component, high-modulus, medium-viscosity, moisture-tolerant epoxy adhesive. Primary use is bonding fresh concrete to hardened concrete. Mix 1:1. This page is a case of 12 x 600 ml cartridges. Gel time is short compared with Pro-Poxy 200, so it is the fast bonding-agent pack, not a crack-injection resin.
