NewLook's water-based Concrete Stains allow you to perform much of the repairs, concrete preparation, and staining during off-peak times. After patching and replacing sections of troubled concrete areas, surfaces can be returned for use within two to four hours after application. These stains work on most concrete and masonry surfaces and are eco-friendly. Designed to last, these stains are available in hundreds of solid and semitransparent colors, including colors from other manufacturers' color charts. New-Look International. 877-763-9566.
