This underwater sealant is particularly popular for its water-resistant capabilities. Unlike some pond sealers, Gold Label can be used directly in your water.

2. TotalPond Waterfall Foam Sealant

[amazon box=”B004DL0XJU”]

Total Pond Foam Sealant is another great pond product that can be used for cracks in your liner. This is a cheaper sealant option. But it works effectively on cracked and leaking areas of your pond.

The Foam Sealant comes in a spray bottle and can be applied to pond liner directly. Unfortunately, you will have to either drain your pond or remove your liner to fix cracks with this product.

Any surface that is sprayed with this product needs to be completely dry!

Otherwise, the sealant will not work. This can make the Foam Sealant a little inconvenient. However, it dries fast and doesn’t take much time to apply. And once it has set into your liner it will keep any water from escaping your pond.

This is by no means the best pond sealer product you can buy. But Total Pond does a good job for the price you pay!

3. Tite-Seal Self Adhesive Double Sided Butyl Pond Seam Tape

[amazon box=”B00AN8BX4Q”]

Tite Seal Tape is an alternative sealant option. The last two products we have shown you were liquid sealers, but Tite Seal uses tape to prevent further leakage. Instead of filling in the cracks in your liner, this product uses an adhesive to cover over them.

You can use this product on its own, for a short amount of time. But it’s recommended that you use other sealant products to fill in the cracks in your liner. A pond coating is one of the best products to pair with this tape. Afterward, you can put the tape over it. This setup will keep your pond area crack free longer.

Tite Seal Tape is a little pricey, but worth the cost. Especially if you don’t want to have to reseal your liner again. You want to make sure that your pond liner is dry before you put on the tape though. And let this product stay dry for at least one day. This way it can completely adhere to the damaged liner.


  • The tape is totally waterproof and seals up your pond well
  • Not hard to use this taping product
  • Sticks readily to dry areas
  • The tape can be used on all types of pond areas


  • Can be a little expensive to get this tape
  • Might need to use a sealing product to keep your leak from coming back

Herco Pond Coating is the next sealing product we will introduce. This pond coater is highly effective and of the best quality. But it costs a lot of money! Many people will not be able to afford this pond sealer. But if you want to invest in a higher-end pond product this could be the brand for you.

Herco Pond is known to have some of the best products on the market. Pond owners like this product because it can be applied to virtually any pond type. Even concrete and tile ponds can use this sealer!

You will want to use a brush or some other tool to get this into cracks and leaks. But it is pretty simple to seal up your pond with Herco! There are a few different sizes that come with your purchase. But the sealant products inside are not any different from one another.

5. Liquid Rubber Waterproof Sealant

[amazon box=”B00NI150Z8″]

Liquid Rubber Sealant is a fairly popular sealant for ponds. This product can be used in several types of ponds and comes in black coloring. You might have to use a few coats to get cracks under control. But overall this is a fairly effective sealant. It’s extremely waterproof, and you can use it on other areas of your home as well. So it’s not just a pond product!

If you have a bigger leak in your pond though, this might not be the best option. So consider this as you choose a sealant to buy.

The Liquid Rubber Sealant works well, but it isn’t made to fill in large holes and cracks. It is good if you want to prime your liner. So consider painting this over your pond liner before it goes into your pond water. This way no leaks will develop in the future.

You can also get the Liquid Rubber in three sizes, a gallon, a quart, or the five gallons. Just choose a size that makes sense for your pond setup.


  • Price is not so bad

6. Tite-Seal Pond Liner Repair Kit

[amazon box=”B009A2EATG”]

Tite-Seal EPDM Pond Liner is an inexpensive kit that can help with smaller cracks and damage. You get a few different items when you purchase this kit. This includes tape, some gloves, a sponge to clean the cracked area, and an applicator.

This is a fairly simple kit that works well for the price. You have to clean any cracked areas and dry them off. But the tape works well and will stay attached to the crack. We recommend using some liquid pond sealer with this product though. This way you won’t have to reapply the tape in the future. Cofair isn’t a bad sealant option. Pond tapes, just need something extra to keep cracks contained.


  • Good at sealing up small pond liner cracks
  • Will not cost you a lot of money
  • Works with many pond types
  • Easy to use this pond sealing kit


  • Not a great option for large cracks and holes in pond liners

Unlike other sealant tapes, Liquid Rubber uses a nano formula to increase the effectiveness of their product. So you know that every dollar you spend on this tape is well worth the cost!

Still, while this tape can be very powerful, you will want to pair it with another type of sealant for better outcomes. The Rubber Liquid solution can be used with the tape. This will keep your pond sealed and leak free for the longest time! Some people might not want to spend extra money on liquid sealers and tape.

But these products are a great solution for pond cracks and damage. You can even get this tape in different sizes.
