How to Repair Pitted Concrete

1. Preparation:

- Remove any loose concrete, debris, or dirt from the pitted areas using a wire brush or a power washer.

- Let the surface dry completely.

2. Cleaning and Etching:

- Apply a concrete cleaner or degreaser to the pitted areas to remove any remaining dirt or grease. Rinse thoroughly with water.

- Use a muriatic acid solution (1:10 ratio with water) to etch the concrete surface. This opens the pores and provides a better bond for the repair material.

- Rinse the surface again with water and allow it to dry.

3. Filling the Pits:

- Select a suitable concrete repair compound or patching material designed for exterior use and filling shallow pits.

- Mix the repair compound according to the manufacturer's instructions. The consistency should be like toothpaste or caulk.

- Apply the repair compound to the pitted areas, pressing it firmly to ensure good contact.

- Use a putty knife or trowel to smooth and level the repair material.

- Allow the repair material to cure and set according to the manufacturer's recommended drying time.

4. Sanding:

- Once the repair material is fully cured, sand the repaired areas using medium-grit sandpaper.

- Sand until the repaired areas are flush with the surrounding concrete surface.

5. Rinse and Seal:

- Rinse the repaired area with water to remove any dust or residue.

- Allow the surface to dry completely.

- Apply a concrete sealer or coating to protect the repaired areas and enhance the overall appearance of the concrete.

6. Curing:

- Allow the sealer to cure and dry completely according to the manufacturer's instructions.

Remember to follow the specific instructions provided by the product manufacturers you choose for the concrete repair compound and sealer. Always wear protective gear, including gloves and safety glasses, when working with chemicals and tools.
