Choosing the Right Patch for Your Pool

Pool Type and Surface Considerations

Your pool’s surface—vinyl, fiberglass, plaster, or concrete—matters a lot. Some silicone patches are better suited for certain materials. Always check the manufacturer’s compatibility list.

Leak Size and Location

Tiny leak or big tear? Wall or floor? Near jets or edges? All of this affects which patch to use. If you’re unsure, get an expert inspection and diagnosis before diving into the fix.

Weather and Water Conditions

Believe it or not, temperature and pH levels can affect the patching process. Choose a product designed for a wide range of conditions. It’ll help you avoid mid-season redos.
