Tips for Applying EPDM Pond Liner Sealant

EPDM Pond liners are a common choice for many pond owners. People use them because they can be a great tool to keep water in place. However, if the liner isn’t placed correctly or gets a crack, there can be leaking issues. To prevent this, make sure you place your liner correctly.

Applying an EPDM pond liner sealant is a great extra step to prevent cracks and leaks from developing as your liner ages. This will keep the water in your pond where it belongs. Proper application of your pond liner sealant will ensure that it does its job for years to come.

Look for Leaks in Your Pond

After you place your liner in your pond, you need to fill it with water. Fill the pond with about six inches of water at a time, then wait and watch the level of the water. If it stays the same, you know there are no leaks in those six inches. If the level lowers, there’s a good chance of a leak, which will need to be repaired.

Repeat this process until the entire pond has been filled. If there are no leaks, you’re in great shape. Of course, you can still apply a pond liner sealant for added protection.

Choose the Right EPDM Pond Liner Sealant

There are a lot of EPDM pond liner sealants available on the market today, so you want to pick the right one. Make sure you purchase a sealant that is made especially for pond liners. Some sealants may claim to be waterproof, but they aren’t able to withstand the constant submersion a pond liner faces.

Liner Material

It’s also important to know the material your pond liner is made out of. Most pond liners are made out of EPDM, but some are made of PVC. Each material will need a different type of liner sealant. For example, Pond Pro 2000 is the perfect choice for EPDM liners, but it can’t be used on PVC liners at all.


Another crucial feature to look for in a pond liner sealant is toxicity. You need to make sure that the pond liner sealant you choose is non-toxic. This will ensure the safety of any fish or plants that you have in your pond.

Even if you don’t have living creatures in your pond, there’s the chance of wildlife stopping by for a drink of water. Using a toxic sealant could cause devastating consequences for the unsuspecting visitors. Plus, non-toxic sealants are better for the environment in general, making it the best choice.

Seal the Leak

If you’ve found a leak, you need to see how big it is to ensure you have enough sealant for the area. Clean the affected area of any debris, oil, or other substances and allow it to dry completely. This will ensure proper adhesion of the sealant to the liner.

Once the sealant has cured completely, fill the pond back up and check for leaks. Assuming you applied the sealant properly, there shouldn’t be any.

Benefits of Using a EPDM Pond Liner Sealant

Choosing to use an EPDM pond liner sealant as preventative care or for crack repair is more affordable and less time-consuming than replacing your liner. Repairing your liner should always be your first line of defense against pond leaks unless the leak is extremely large.

Choose Pond Pro 2000

Using the right pond liner sealant will help you repair your pond without needing a new liner. Pond Pro 2000 is the best sealant available for EPDM pond liners. It’s guaranteed for three years and comes with a five-year warranty so that you can enjoy years of a leak-free pond.
