What are the best methods to repair spalling on concrete bench surfaces?

Spalling on concrete bench surfaces is a common issue caused by weathering, freeze-thaw cycles, or poor initial construction. To restore your bench, follow these effective repair methods:

1. Clean the Area: Remove loose concrete and debris with a wire brush or pressure washer. Ensure the surface is dry before proceeding.

2. Apply a Bonding Agent: Use a concrete bonding adhesive to help the new material adhere to the old surface.

3. Patch with Repair Mortar: Fill the spalled areas with a high-quality concrete repair mortar, smoothing it evenly with a trowel.

4. Seal the Surface: After curing, apply a concrete sealer to protect against future damage.

For severe spalling, consider professional resurfacing or replacement. Regular maintenance, like sealing and cleaning, can prevent future issues. DIY repairs are cost-effective for minor damage, but extensive spalling may require expert intervention.
