| − | #Repair cracks in the concrete. Clean out the crack(s) with a wire brush. Vacuum or blow out any dust and dirt, or use a broom to make sure the crack is clean. Fill the crack with masonry crack filler. Depending on the brand, either apply the filler with a scraper, or a caulking gun (if necessary). To fill deeper or wider cracks, fill them by a quarter-inch (six mm) at a time. Allow the product to dry between applications according to label instructions.<ref>https://www.youtube.com/watch?v=8qUaFKv070A</ref> | + | #Repair cracks in the concrete.
