How Do You Repair a Swimming Pool?

To repair a concrete pool, expose the damaged area and apply pool patching material. The patch should remain damp until it has set. Most repairs can be completed in a few hours.

  1. Prepare the damaged area for repair

    If necessary, drain the water to expose the damaged area. Use a grinder to expand the cracked area to 1/2 inch in diameter, and remove an additional 1 inch on each end of the crack. Apply caulk 1/4 inch inside the cracked area, and allow it to dry completely.

  2. Apply pool patch

    Purchase a product that is specifically designed to patch concrete pools, and dampen the cracked area with water. Apply the repair compound with a trowel by pressing the material into the crack. Smooth the exterior of the patched area, and use a sponge or another tool to create a surface on the patch that matches the existing pool finish. If pool patching material isn't available, a mixture of Portland cement, acrylic bonding epoxy and sand can be used.

  3. Cover the patched area with water

    Fill the pool with water to cover the patched area, or cover the patched area with a wet cloth until it sets for the recommended amount of time.
