You primarily need to be concerned about the moisture level in concrete when you are dealing with a basement or other below-ground part of your house. If you find any indication of moisture in your subterranean space, consider calling in a professional for further testing and moisture control solutions.

Flooring professionals can typically apply epoxy within one or two days, depending on how much preparation or repair the old floor needs before application. However, you’ll need to wait after the application is complete to use the flooring. While you can walk on the epoxy flooring before it fully cures, it can take up to 72 hours for the epoxy floor to fully dry and be ready for full use.

The actual moisture level that is acceptable for your concrete floor depends on what primer or flooring material you plan to install above it. For this reason, you should check the manufacturer’s instructions for the exact details.

Generally, the moisture levels should be 3.5% to 4.5%, although it does vary. Some products can handle higher levels of moisture, so you should always test your concrete before purchasing your flooring materials.
