How to Repair a Concrete Seawall
- 1). Brush out debris from any cracks and pitted parts of the wall with the wire brush.
- 2). Apply enough water to the cracks and pits so that the concrete is just damp to the touch.
- 3). Brush on the concrete bonding liquid with a standard paintbrush. Be sure to fit the brush all the way into the back of deep cracks.
- 4). Mix the concrete with water in a bucket in the ratio outlined on the packaging.
- 5). Scoop the concrete into the cracks and pits with the pointed trowel and be sure to force it as far back into the cracks as it can go.
- 6). Smooth the concrete level with the existing surface by using the flat trowel.
- 7). Allow the concrete repairs to dry until they are damp to the touch, then moisten the end of a broom and sweep the broom over the repairs for a textured look. The repairs will typically cure within 24 hours.
