Learn how to repair and patch small to midsized cracks in your swimming pool, as well as when to call for help from professionals.
1. In concrete pools, hairline cracks can simply be patched with chorlinated rubber or epoxy swimming pool paint. Most small hairline cracks can safely be ignored in fiberglass pools, as they’re just a normal sign of the pool aging.
2. For slightly larger cracks (less than 1/8 of an inch), patch cracks with special epoxy compound that is made just for concrete pools or with fiberglass patch kits for fiberglass pools. Always follow the instructions from the manufacturer of the product you’re using.
3. If cracks are larger than 1/8 of an inch or more than a foot long, it’s time to call the professionals.
