Concrete resurfacing and concrete overlay are terms often used interchangeably to describe the process of applying a new, thin layer of pre-blended concrete over an existing slab. This process enhances the durability and appearance of the concrete, giving it a fresh look without the high cost of a full replacement. The new layer is typically between 1/4-inch and 1-inch thick, significantly less than the 4 inches required for a new slab, and can be stamped, colored, or textured for a custom finish.

While the terms are often considered the same, their meaning can sometimes vary by contractor. Some may use "overlay" to describe a thicker application that adds structural integrity, while "resurfacing" might refer to a thinner layer intended for cosmetic upgrades. Other common names for this process include concrete restoration, concrete refinishing, and concrete rejuvenation.

You can put pavers over concrete following a similar procedure as above, but there are a few additional risks you need to be aware of—like stability, drainage, and the patio’s thickness. Once you lay a paver patio over concrete, it will be nearly impossible to treat any issues that your concrete may face, like cracks or water pooling. So while you may save some time and money on concrete removal and site prep, it may cost you more in the long run.

Earth tones, such as brown, beige, and tan, are some of the most popular colors for stamped concrete. You can also use reds and grays to mimic the look of brick or stone. The right color for your project depends on your area and the look you’re going for.

Yes, you should seal your exposed aggregate concrete to keep it protected from the elements and reduce the risk of cracking and concrete spalling. You’ll need to invest in the cost of resealing your concrete about every three years to keep it in good condition. Unsealed exposed aggregate concrete is susceptible to water damage, stains, chips, cracks, and abrasion. Sealers are available in various finishes and levels of gloss. Outdoor exposed aggregate concrete should be sealed with a non-yellowing, UV-resistant sealer to preserve the look of the finish.
