This invention relates to an epoxy composition especially designed for use as a primer for sealing and filling small pores in concrete. Advantageously, the composition is a low temperature curing, sag-resistant epoxy primer, which provides good adhesion to concrete and to a polyurea coating applied to the primed concrete. Advantageously the epoxy primer is curable at a temperature below 40°F and comprises an admixture of two parts, Component A and Component B; wherein Component A comprises a crystallization resistant reactive epoxy resin and Component B comprises an amine curing agent. The resulting primer bonds to concrete at 200 psi or greater, when measured by ASTM D 4541.
