Concrete Finishing questions, answered by experts

Concrete should be at least 2 inches thick to maintain its stability and quality. Most concrete slabs fall between 4 and 6 inches thick, but you should be careful not to make the new slab too high or heavy. If you're considering a stamped concrete overlay, hire an experienced stamped concrete contractor to determine the ideal concrete thickness.

When you are laying hardwood flooring—or any other material that does not flex well with humidity—you will want to check the moisture level of your subfloor before proceeding. Flooring like luxury vinyl tile and bamboo performs better than more rigid materials in environments where moisture might be present. However, thorough testing is always an excellent preventative measure to control and monitor water in your home.

Concrete stain should last for five to 20 years, depending on the type of stain you use. Acid-based concrete stains can last up to 20 years if they’re well-maintained, though you'll do well to reseal the concrete every few years. Water-based concrete stains will last about five years before the color begins to fade, especially on outdoor concrete projects that see UV light, rain, and snow. Most homeowners reseal their stained concrete every three to five years to maintain the color, regardless of the type of stain they used.

A layer of exposed aggregate concrete should be 1 to 2 inches thick if you’re installing it on top of existing concrete. If you’re pouring a new slab with the finish, slab thickness will depend on the application. Exposed aggregate concrete driveways should be 4 to 6 inches thick in most cases or 8 to 12 inches for commercial vehicles. Sidewalks, patios, and walkways should be 4 inches thick.

The curing time for troweled concrete depends on different factors. The type of concrete mix used in the project can impact the time it takes for the concrete to cure, and climate conditions such as moisture and humidity can as well. It can take several days to a few weeks for concrete to fully cure, depending on the concrete mix.
