How to patch a pool liner – Techniques/Tips

  1. Check to know where the problem is coming from. A leak must have occurred, the bead might have loosened, or the liner needs a replacement. Don’t assume that erosion could be the cause.
  2. When you know where the problem is, repair leaks using a vinyl pool repair kit. Underwater leaks require a wet patch kit.
  3. Coins can specify leaks. Switch off your pool filter for an hour. Spray dye close to your marker, and if it is drawn to it, then you have discovered where the leak is.
  4. You can cover the leak with patch kits temporarily. Most people use heavy plastic for patches. The pressure from the water will keep it firm.
  5. Make a deep ravine to drain the water. Take up the pool liner and pour dry sand with the use of a funnel. Fill empty spaces before using your swimming pool repair kit material to patch. Cut a round patch a little bigger than the tear and apply cement to it. If the leak is underwater, allow the adhesive to dry before folding it in half. Replace the temporary patch with the new one.
  6. You can blow-dry to help the liner back in place. You can realign your bead by applying boiled water.
  7. There is a need for you to replace your vinyl liner if there are too many holes or if it is old.
