Yes, the Leakmaster Flexible Sealer can be used to repair underwater cracks on fiberglass pools. This sealant is designed to bond to a wide range of surfaces, including vinyl, concrete and fiberglass. For hairline cracks in fiberglass, this sealer provides a flexible, waterproof barrier.
For larger structural cracks, it’s best used as a temporary fix. Long-term repairs usually require fiberglass patching with resin and mat.
