Owning a pool brings a lot of joy, but it can also bring some headaches. If you've noticed water levels dropping faster than they should, you may have a leak. If the hole is in an above-ground pool, the water level will drop to the height of the hole. If the hole is near the bottom of the pool, the water loss could be extensive. The good news is that patching a hole in a plastic pool is a relatively straightforward process, and there are several methods you can try.
Characteristics and Values Table for Patching a Hole in a Plastic Pool
| Characteristics | Values |
|---|---|
| Hole Size | Small holes can be patched with glue or tape. Large holes may require a plug or a new pool. |
| Hole Location | Holes near the bottom of the pool or the floor can cause extensive water loss and collapse the pool. |
| Materials | Vinyl repair glue, soft plastics glue, duct tape, packing tape, Tear-Aid, Shoe Goo, hot glue gun, epoxy, vinyl pool repair patches, etc. |
| Patching Process | Clean the area around the hole. Dry thoroughly. Apply glue or tape to cover the hole. Smooth out any air bubbles. Allow the adhesive to cure. |
| Temporary Fixes | Duct tape, packing tape, or waterproof band-aids can be used temporarily until a proper patch can be applied. |

What You'll Learn

Using tape to cover the hole
Firstly, you need to select the right tape for the job. Duct tape is a popular choice and is known for fixing most things. Packing tape can also be used, and for vinyl pools, black electrical tape is a good option as it sticks to itself.
Before applying the tape, ensure the area is clean and dry. Cut a piece of tape slightly larger than the hole. You can then stick it over the hole, rubbing it onto the surface to ensure it is secure. If your pool is full of water, you can still apply the tape underwater, pressing it firmly onto the hole.
Once the tape is applied, check for any leaks. If you notice any, simply add another layer of tape over the top. This method will help you get through the rest of the swimming season, and you can always add fresh tape when the old tape starts to fail.

Applying glue to seal the hole
Before applying glue to seal the hole in a plastic pool, it is important to clean the area around the hole. Use rubbing alcohol and a rag to clean the surface of the pool, removing any dirt or debris. Ensure the area is completely dry before proceeding.
Once the surface is clean and dry, you can begin applying the glue. There are various types of glue that can be used for this purpose, such as vinyl repair glue, soft plastics glue, or a two-part epoxy mixture. Choose a glue that is suitable for the material of your pool and follow the instructions on the packaging for mixing and application.
For a hot glue gun, remove the glue stick and heat the tip of the gun. Carefully use the hot tip to melt the edges of the hole, creating a smooth surface. This will help seal the hole and prepare it for further application. Be cautious when handling the hot glue gun to avoid any burns.
Apply a thin coat of glue over the hole, ensuring it covers the entire area. If using a glue gun, slowly and carefully fill in the gap, taking care not to burn the plastic or create a larger hole. Allow the glue to dry completely according to the manufacturer's instructions.
After the glue has dried, inspect the area to ensure it is sealed. You may need to apply multiple coats of glue for a stronger hold. Follow up with a patch for added reinforcement if desired, but be sure to let the glue cure completely first.

Using a patch kit
If you have a hole in your plastic pool, you can use a patch kit to repair it. The process is relatively simple and can save you thousands of dollars and further damage.
First, you need to identify the area of the leak. If your pool is already empty, you can skip this step. If not, make sure the water is clean and calm, and put on your snorkelling gear and goggles to search for the leak. If you can't find it, add a small amount of pool dye around the pool's liner. Once you've located the leak, give the area a thorough cleaning.
Next, you'll need to prepare your patch. Cut a piece of the patching material from your kit, ensuring it's slightly larger than the hole—around 1" past the circle of the hole. If your pool is empty, you can apply the patch now. If your pool has water in it, use a wet patch kit.
Hold the patch over the hole and slowly open it while smoothing it onto the pool liner. Press out any air bubbles and then hold the patch in place for about two minutes. The adhesive needs time to cure and reach its full strength, so resist the urge to tug on the patch. Some products recommend putting weight on the patch for 24 hours while it cures. If possible, rest a pool cleaner head or a clean brick wrapped in plastic on top of the patch.
If you're concerned about the risks associated with PVC exposure, look for patch kits with bisphenol A (BPA)-free patching vinyl. You can also find peel-and-stick patches, which may be easier to use. For a soft-sided pool, follow the same process, but when patching the top ring, fully inflate it, mark the hole, and apply adhesive around it and to the clear patch before applying. Then, slightly deflate the ring so the adhesive can cure without pressure.
Remember, the most difficult area to repair is near the plastic fittings of the liner's bed, and in this case, your best option may be liner replacement. If your pool liner is starting to deteriorate, many patches won't cut it, and you may need to contact a professional for advice.

Filling the hole with epoxy
First, ensure that the pool is clean and dry. This is important because epoxy needs a clean and dry surface to adhere properly. Next, cut two standard vinyl pool repair patches to fit 1 inch beyond the circle of the hole, both inside and outside. You should be able to find these at your local Wal-Mart or hardware store.
Now, it's time to mix the epoxy. Epoxy usually comes in two parts that need to be mixed together. Follow the instructions on the packaging and mix enough epoxy to affix the first patch to the outer wall of the pool. Smooth out the epoxy and allow it to dry completely. Repeat this process for the inner wall, but this time, use a little extra epoxy to fill and smooth over the hole, ensuring a nice, even surface.
Once the epoxy is dry, take any remaining epoxy and smear it all around the edges of the patches, both inside and outside the pool. This will create a smooth, watertight seal and help the patches last for years. It is important to note that the adhesion of epoxy to plastic can vary, so be sure to follow the instructions on the epoxy packaging carefully and consider using an epoxy specifically designed for plastic.
Additionally, if you are unable to find vinyl repair patches, you can also use duct tape as a temporary solution. Simply cut a piece of duct tape slightly larger than the hole and stick it onto the pool, either over or under the waterline. This will help keep the water in until you can properly patch the hole with epoxy and vinyl patches.

Fixing a pool liner
The first step is to identify the location and size of the leak. If your pool is losing an inch or more of water per day, it is likely due to a leak. You can use the bucket test to confirm that your suspected leak is not just evaporation. Once you have confirmed that there is a leak, you can use duct tape to temporarily fix it. Cut a piece of duct tape slightly larger than the hole and stick it right underwater, rubbing it onto your liner. This will help keep the water in your pool until you can properly patch it.
To permanently patch a pool liner, you will need to purchase a patch kit. Choose a kit that is suitable for the material of your pool liner, such as vinyl or plastic. The kit should include a patch and an adhesive. Cut the patch to fit 1 inch past the circle of the hole, both inside and outside. Clean and dry the area around the hole, and then apply the adhesive to the patch. Slowly and gently open the patch while smoothing it onto the pool liner. Press out any air bubbles and hold the patch in place for two minutes. Some patch products recommend putting weight on the patch for 24 hours while the adhesive cures.
If you are unable to find a patch kit, you can also use a hot glue gun to repair the hole. First, remove the glue stick and clean the tip of the gun. Use a utility knife to trim a small piece off the rim of your pool and wash your trimming thoroughly. Clean around the hole with alcohol and dry it thoroughly. Next, use the tip of the hot glue gun to melt the edges of the hole and use the pool trimming to weld and fill in any gaps.
