How to repair surface scaling on concrete seating caused by improper curing?

Surface scaling on concrete seating due to improper curing can be unsightly and weaken the structure. Here’s a step-by-step guide to repair it effectively:

1. Assess the Damage: Inspect the scaled areas to determine the severity. Remove loose concrete fragments using a wire brush or chisel.

2. Clean the Surface: Wash the affected area with water and a mild detergent to remove dirt and debris. Allow it to dry completely.

3. Apply a Bonding Agent: Use a concrete bonding adhesive to ensure the repair material adheres properly to the existing surface.

4. Patch the Scaling: Mix a high-quality concrete patching compound and apply it evenly over the damaged area. Smooth it with a trowel to match the surrounding surface.

5. Cure Properly: Keep the repaired area moist for at least 7 days by covering it with plastic or applying a curing compound to prevent future scaling.

6. Seal the Surface: Once cured, apply a concrete sealer to protect against moisture and freeze-thaw cycles.

Prevent future issues by ensuring proper curing during initial installation: maintain moisture for at least 7 days and avoid premature drying. Regular maintenance and sealing can also extend the lifespan of concrete seating.
