How to Stop a Pool Leak with Flex Tape

Nothing ruins a family BBQ or some fun in the sun like an unexpected pool leak. It’s inconvenient and pool liners can cost hundreds (sometimes thousands) of dollars to replace. That’s why we recommend keeping Flex Tape nearby.

The next time you find yourself with this problem, just use Flex Tape and your pool leak will be repaired in a matter of minutes. It’ll save you time, money, and energy – allowing you to get back to what’s most important. (The fun, of course!)

Here is our step-by-step guide on how to stop a pool leak with Flex Tape:

What you’ll need:

  1. Flex Tape
  2. High-quality, Sharp Scissors

1) Clean the Surface.
Before applying Flex Tape, it’s important that your surface is clean of oil, dirt, and grease. Grab a rag and cleaning solution to wipe your pool down if there’s any grass, dirt, or mud around the tear or crack in your pool.

flEXPERT Tip 1: One of the most common questions we receive from our customers is, “Should I apply Flex Tape on the inside or the outside of my above-ground pool?” The answer is, “both!” Flex Tape not only works on dry and wet surfaces, but it works underwater too! (For in-ground pools, patching the inside of the liner is the only option.)

2) Cut & Patch it!
Cut two appropriate sizes of Flex Tape (while the backing is still on). It’s important that you cut your Flex Tape larger than the area of the pool leak.

Remove the backing from each piece and apply one piece to the leak on the inside of the pool. Then, apply the other piece to the leak on the outside of the pool wall. This will give you double protection.

While applying the Flex Tape, be sure to use a lot of pressure. Continue to press down firmly to remove any air pockets or bubbles.

flEXPERT Tip 2: To get rid of air pockets and bubbles, use your fingers, a rubber roller, or a plastic squeegee.

3) Give It Time.
For best results, wait twenty-four (24) hours. There’s no curating time for Flex Tape. However, it’ll reach its maximum hold after it’s been on the surface for 24 hours.  The longer it sits, the stronger the bond becomes. It’ll create a waterproof, airtight seal that will stop your pool from leaking.

flEXPERT Tip 3: Apply Flex Tape to your pool ladders to create a strong grip to hold on to – just wrap the ladder’s handlebars with Flex Tape.


Reminder: Flex Tape is a semi-permanent fix. It’s meant to be used as a temporary, emergency repair.
