Why Do You Need to Fix Above Ground Pool Liner That Has Slipped?

It’s essential to fix a slipped pool liner as soon as possible. Without immediate attention, it can lead to further problems down the line, such as water loss, mildew build-up, and even damage to the underlying structure of your above- ground pool. In some cases, the entire liner may need replacing if left unchecked for too long.

Needed Tools

Before you start the process of fixing your pool liner, make sure to have the following tools on hand:

  • Tape measure
  • Utility knife
  • Reaming tool or screwdriver
  • Sandpaper
  • Vinyl adhesive patch kit
  • Replacement liner (if necessary)

Now that you have the tools needed, here’s a step-by-step guide on how to fix a slipped pool liner

10 Steps on How to Fix Above Ground Pool Liner That Has Slipped

Step 1: Measure the Pool.

Using your tape measure, check the circumference of the pool walls and note any discrepancies in height or width. This will help you identify which sections of the liner have slipped and by how much.

Using Your Tape Measure

Step 2: Trim Excess Material.

If there is excess material around the sides of the pool, use your utility knife to trim it away carefully. Trimming would also help you identify and address uneven tension points in the liner. Then excess material can be thrown away.

Step 3: Ream Out the Slip Areas.

Using your reaming tool or screwdriver, gently push and pull along the sides of each slipped area. This will remove any wrinkles that are causing tension and make it easier for you to re-attach the liner in place. 

Step 4: Sand Away Unwanted Material.

Using your sandpaper, lightly abrade the edges of the liner where it has come away from the pool walls. This will help create a smooth and even surface for adhesion. A smooth surface is key to making sure the liner stays in place.

Using Your Sandpaper

Step 5: Apply Vinyl Adhesive Patch Kit.

Once you have sanded down the surface, use a vinyl adhesive patch kit to attach the liner back into place. Make sure to read and follow all instructions included with your patch kit for the best results.

Step 6: Let It Dry.

Once you have applied the adhesive patch kit, allow it to dry for 24 hours before refilling your pool with water. Letting it dry properly will ensure that the liner is securely attached.

Step 7: Refill with Water.

After 24 hours, it’s time to refill your pool with water to check for any further issues. Keep an eye out for any additional slips or wrinkles that may have occurred during the re-attachment process. If everything looks good, your pool is ready to be used again.

Step 8: Monitor the Pool Closely.

Even after your initial fix, it’s important to keep an eye on your pool liner for any further signs of slipping. Regular checks can help you spot and address problems before they worsen, so don’t forget to give it a periodic once-over.

Step 9: Replace the Liner if Necessary.

If you’ve done everything possible to fix your pool liner and it still continues to slip, then it may be time to consider a full replacement. It’s always best to work with a professional when replacing the liner so that it is installed correctly and securely.

10 Safety Precautions to Take

1. Shut Off the Power to the Pool Pump

Be sure to shut off any electrical power associated with the pool pump before beginning repairs. This will ensure your safety and prevent electric shock.

2. Put on Protective Gear

Wear protective clothing when handling chemicals and pool liners, such as rubber gloves, eye protection, and a long-sleeved shirt.

3. Remove Any Debris From the Pool

Any leaves, dirt, or other debris should be removed from the pool before attempting to fix a slipping liner. This will help prevent further damage to the liner and make it easier to work with when making repairs.

4. Check the Ground Around the Pool

Make sure that there are no roots, rocks, or other debris that could cause the liner to slip further. Debris can cause damage to the liner and make it difficult or impossible to repair.

5. Determine the Cause of the Slipping

If you can determine what caused the liner to slip, then you can take steps to prevent it from happening again in the future. Common causes include ground movement, water levels that are too low, or incorrect installation of the pool.

6. Dry the Area Where the Liner is Slipping

Be sure to dry the area that has slipped in order to ensure a better bond between the pool wall and liner when making repairs.

7. Apply Adhesive to the Area

There are various types of adhesives available for repairing pools, so be sure to read the instructions carefully before using one. Apply the adhesive to the area where the liner is slipping and then press down firmly.

8. Use a Patch Kit if Necessary

If there is a tear or other damage to the liner, you may need to use a patch kit in order to repair it properly. Follow instructions carefully when using these kits, and be sure to apply them as directed.

9. Adjust the Water Level

Make sure that the pool has enough water in it to keep the liner from slipping. If necessary, adjust the water levels accordingly in order to ensure a good fit for all areas of the liner.

Adjust the Water Levels Accordingly

10. Test for Leaks

Once repairs have been made, test for any leaks by running a garden hose over the area. If there are any leaks, you will need to make further repairs in order to ensure that the liner does not slip or tear again.

Taking these 10 safety precautions before and during repairs can help keep you safe while fixing a slipping above-ground pool liner. Be sure to read instructions carefully and take all necessary steps to ensure a secure and successful repair.
