No, hairline cracks in concrete are generally not a problem as they do not impact the strength and longevity of the concrete. Generally, cracks less than 0.3 millimeter wide don’t impact the structure. Hairline cracks can grow over time and weaken the structure, such as in a home foundation. Some hairline cracks can also cause leaks in a foundation. It’s important to watch the cracks to see if they grow. Contact a concrete contractor if you notice cracks exceeding 0.3 millimeter wide.

A concrete overlay on an existing slab can range from 1/4 of an inch to 2 inches thick, though a minimum of 2 inches is often recommended to ensure stability and quality. The ideal thickness depends on the condition of the existing concrete and the depth of any planned designs or imprints. Before applying the overlay, it's important to repair and clean the surface, then apply a primer. For specialized work like a stamped concrete overlay, hiring an experienced contractor is recommended to determine the correct thickness and ensure the new layer isn't too high or heavy. For context, most standard concrete slabs are between 4 and 6 inches thick.

A layer of exposed aggregate concrete should be 1 to 2 inches thick if you’re installing it on top of existing concrete.

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.

To preserve a concrete coating, routine maintenance should include regular sweeping and cleaning to remove debris and dirt, promptly addressing any spills to prevent staining, and applying a sealer as the manufacturer recommends.
