Proper curing and sealing dustproofs the concrete and acts as a curing membrane which helps the concrete remain hydrated and reach the strength it was designed for. Some sealers enhance the colors of decorative concrete making them look more vibrant. Sealers will tend to make the concrete easier to clean, as well as more stain resistant, whether it is a spilled glass of red wine on your decorative concrete patio, or an oil spot on your motor court or driveway.
