Use these techniques to make a permanent patch above the water – or beneath it.

Unchecked pool leaks dampen more than summer fun – they waste water, over-tax equipment, and can even lead to long-term damage to your yard or home.

If your above-ground or below-ground pool’s vinyl liner has a hole, it isn’t hard to patch it.  HH-66 is the industry’s leading PVC vinyl adhesive – it’s waterproof, weather and temperature resistant, and forms bonds stronger than the vinyl your pool liner is made from.  And yes, you can even use it to patch your pool underwater.

Here are two techniques for making a permanent patch to your pool’s vinyl liner, either above or below the water line.

Patch a vinyl pool liner or inflatable out of the water

1. Prepare

  • Cut patch to appropriate size, ensuring a two-inch overlap on all sides.  Round corners to minimize peeling.
  • Clean surfaces with alcohol wipe provided (or HH-66 Thinner).  Sand any glossy surfaces lightly.

2. Apply

  • Use brush to apply an even coat of HH-66 TF Vinyl Cement to both surfaces to be joined.
  • Allow cement to set until tacky, typically around three minutes.  Cement will remain tacky for just a few minutes.

3. Attach

  • Press patch on firmly while tacky.
  • Apply pressure throughout to remove air bubbles.
  • Allow to bond for at least an hour before use.  Strongest hold achieved after one day.
  • Remove any excess adhesive.

Patch a vinyl pool liner underwater

1. Prepare

  • Cut patch to appropriate size, ensuring a two-inch overlap on all sides.  Round corners to minimize peeling.
  • Clean the vinyl patch with alcohol wipe provided.  Ensure the liner surface is free from debris.

2. Apply

  • Use brush to apply an even coat of HH-66 TF Vinyl Cement to the vinyl patch.
  • Allow cement to set until slightly tacky.
  • Fold the vinyl patch in half loosely, while the adhesive on the inside is slightly tacky.

3. Attach

  • Submerge the folded patch underwater.  Unfold the patch and position it over the damaged area.  Press the patch firmly onto the vinyl.
  • Apply pressure throughout to remove air bubbles.
  • Allow to bond for at least an hour.  Strongest hold achieved after one day.
