A concrete overlay is a thin layer of concrete applied over an existing concrete surface to improve its appearance and durability. This technique is often used to repair damaged or worn-out concrete, providing a fresh, new look without the need for complete replacement. Overlays can be customized with various colors, textures, and patterns, making them a popular choice for both residential and commercial spaces. The application process involves cleaning the existing surface, repairing any cracks, and then pouring the overlay mixture. Once set, the overlay can be sealed for added protection. This method is cost-effective and environmentally friendly, as it reduces waste by reusing the existing concrete structure.
