A concrete overlay is a decorative and functional solution for resurfacing existing concrete surfaces. It involves applying a thin layer of cement-based material, usually between 1/16 to 1/4 inch thick, on top of the existing concrete surface to improve its appearance and durability. The overlay can be colored, stamped, or textured to create a wide range of design options, including replicating the look of natural stone, tile, or wood. Concrete overlays are a popular choice for both interior and exterior applications, including patios, pool decks, driveways, and floors, as they offer a cost-effective and long-lasting way to transform and update concrete surfaces without the need for expensive removal and replacement.
