Method 2: Epoxy Putty Fixes
When to Use Epoxy
Epoxy works best for cracks in concrete pools or sealing around fittings.
Mixing and Application
Knead the putty until uniform, then press it into the damaged area.
Strengthening the Seal
For maximum durability, smooth out the epoxy with a wet glove. Learn more about epoxy applications.
Method 3: Underwater Adhesives
Pressure-Sensitive Adhesives
These adhesives bond instantly even under pressure.
Long-Lasting Bonding
