Concrete overlays are a game-changing solution for those looking to revamp old, worn-out concrete surfaces without the hassle of complete replacement. Whether you want to smooth out imperfections, add decorative appeal, or strengthen a high-traffic area, a concrete overlay provides a fresh, durable, and visually appealing finish.
By applying a thin layer of specialized concrete mix over an existing slab, overlays can restore floors, patios, driveways, and commercial spaces without the cost and effort of ripping out and replacing the old concrete. They come in various types, from stamped and self-leveling overlays to ultra-thin microtoppings, allowing for customization based on aesthetic preferences and functional needs.
But is a concrete overlay the right solution for your flooring project? Let’s explore the types, benefits, costs, and installation tips to help you make an informed decision.
