From chuck pease of EXTREME DRYWALL CONCEPTS on July 20, 2020:
Short answer, one would need to know service exposure, intent and what the environment of said concrete would be in.

From Richard Devick of UCI PAINTS on July 16, 2020:
The coating selected MUST have alkali resistance and enough solids to fill in application fissures. Also, the coating selected is dependent on whether the new concrete is vertical or horizontal, poured in place or tilt-up.

From Dave Helmholdt of Repcolite Paints on July 13, 2020:
The most important factor in selecting a coating is what do you need or want it to achieve? Do you need the coating to perform under certain conditions? Are aesthetics more important than how the coating performs? Are there issues such as dampness or another condition that will affect the coating choice? The original question is too vague to be answered properly.

From Mike Rutherford of Conspectus (QLD) Pty Ltd on July 13, 2020:
Surface preparation is an important factor when selecting coatings for new concrete. The manufacturer of the coating may have specific requirements for surface preparation, including the surface profile and moisture sensitivity. Improper surface preparation can impact the manufacturer’s warranty. The properties and application requirements of the coating must be determined prior to selection of a surface preparation method.
