Where Epoxy Fails and This Does Not
Epoxy is a good floor in a dry, temperate room. Put it in a plant that washes down with 180-degree water and it debonds, because the coating and the slab expand at very different rates and the bond line takes the difference. Urethane cement is formulated to move with the concrete, so thermal shock does not shear it off.
The second difference is moisture. Epoxy needs a dry slab and a low vapor emission rate, and on a slab-on-grade with no vapor barrier, common in older Ventura County industrial buildings, that condition is often impossible to meet. Urethane cement is breathable enough to go down over slabs that would blister an epoxy within a year.
