Step 1 · Clean the Damaged Area

Using a stiff brush or wire brush, scrub the damaged area to dislodge any loose concrete, dirt, or debris. For stubborn dirt or efflorescence, a pressure washer or garden hose with a strong spray can be used. After brushing, use a shop vacuum or compressed air to remove all dust and fine particles from the crack and surrounding area. Ensure the area is completely dry before proceeding.
