Yes, use 2 coats of NovaTuff P-505 Epoxy Primer at 1 gallon per 150 to 200 square feet. Concrete must be more than 28 days old. The concrete may outgas with the first coat but the second coat will complete the seal. If temperatures are high, it can be better to apply the primer coats at night. The next coating application needs to be applied within 36 hours.
This is the same primer system that we recommend for concrete fountains.
