Concrete overlays are a great way to give your concrete a new look and make it last longer. Generally, they can last anywhere from 10 to 25 years, depending on the quality of the material used, the amount of preparation work done on the concrete, and the amount of regular maintenance. With proper care and maintenance, a concrete overlay can last up to 20 years. To ensure that your concrete overlay lasts as long as possible, it is important to use a penetrating sealant when installing it.
This will make it more resistant to stains and scratches. Additionally, regular sweeping and mopping will help keep dirt out of the overlay. Concrete overlays are also popular because they can be used to imitate other materials without replacing the existing concrete. This is done by pouring a thin layer of concrete on top of the existing concrete.
This new layer is specially designed to adhere to the old concrete and is extremely durable. If installed and cared for properly by a professional, it can last up to 10-20 years. GCI's epoxy product, GSPEC, is designed to create a floor that looks like self-leveling cement with a 50-year durability. It is also important to note that if the slab underneath the overlay is cracked or damaged, the overlay will eventually start to crack as well.
This is because the overlay and the slab underneath expand and contract at different rates due to different coefficients of thermal expansion. Patterned concrete coatings are also an environmentally friendly option as they do not require replacing the existing concrete. However, they can be more expensive than other types of flooring due to textures or inlays and other design elements added to them. When applying an overlay, it is important to keep in mind that temperatures should not be below 40 degrees as this will slow down the chemical reactions that strengthen concrete, significantly weakening it. Overall, concrete overlays are a great way to give your concrete a new look and make it last longer. With proper installation and maintenance, they can last up to 20 years.
