How to Use Pond Leak Sealer

If you own a manmade pond, then nothing probably frightens you as much as the thought of it springing a leak.

Unfortunately, no matter how well you built your pond, a leak is always possible. This is why it’s a good idea to keep a close eye on yours, especially when the weather changes. Ideally, you’ll want to catch a leak while it’s small, before it grows into a much bigger problem.

Either way, you’re going to need to know how to apply pond leak sealer, which we’ll now explain step-by-step.


Find the Leak

This may seem like a no-brainer. After all, won’t it be extremely obvious where the leak is?

However, this is easier said than done. You also want to make sure that there is an actual leak. The water level could be going down for other reasons: evaporation, animals drinking from it over time, trees getting to it through their roots, etc.

Furthermore, you want to make sure there isn’t more than one leak. This process could definitely take a few hours to complete, but it’s essential you get it done before proceeding with applying pond leak sealer.

With any luck, the leak will be noticeable because water begins pooling at the surface nearby. If you think you’ve found the leak but aren’t sure, you can sprinkle some food dye into the water to see if it is sucked to the wall.

Pump Water Out

In some cases, finding the leak will be easy because the water level has dropped so dramatically it’s immediately clear where it’s occurring.

In other cases, you’ll catch the leak while it’s still underwater. This will mean you have to pump water out until it’s exposed and you can continue with your pond leak sealer. Obviously, most of you won’t have a pump, but this can be rented. It’s the same kind you’d use for getting water out of a basement.

Apply Your Pond Leak Sealer

When the water level has been dropped sufficiently, inspect the leak. Make sure it’s free of any debris before you move forward. Any tiny pieces of concrete could interfere with your sealer and cause another leak to happen in the near future.

Once it’s cleaned out, go ahead and apply your pond leak sealer with a paint roller. Wear a paper mask when doing this so you don’t accidentally breathe in any chemical fumes. Wear gloves, too, as this stuff can irritate your skin and, as you can imagine, will be difficult to wash off.

Let the Sealer Dry

The label on your sealer should tell you how long it needs to dry before you can expose it to water again. Make sure you don’t rush things or, again, there will be another leak to contend with in the near future. Once it’s good and dry, you can add water back to your pond.

Ideally, you want to make sure you build your pond properly to keep this frustrating problem from happening in the first place. If it’s too late, the best possible outcome is that you catch the leak early so you can act to fix it right away.

The Benefits of a Rubber Pond Coating

Manmade ponds come in all shapes and sizes, but, no matter which version you go with, the result can be a more impressive and enjoyable commercial or private property.

Whatever you have in mind for your pond, it needs to involve a coating, or leaks will eventually occur and you’ll have a lot of work on your hands – costly, labor-intensive work, at that.

Below, we’re going to detail why a Rubber Pond Coating is the type you should choose for this important task.


Using a Rubber Pond Coating Instead of a Liner

Many people simply use liners for their ponds. They come prefabricated, so it’s easy enough to dig a hole for it, put it in the ground and then pour the water.

The obvious problem is that liners don’t give you much flexibility where your pond’s shape is concerned. Obviously, you are limited to the types of liners available.

However, they’re also not as durable as a coating. Fortunately, coatings are just as easy to apply despite the fact that they give you more options for the shape of your pond.

Rubber Coatings Are Extremely Affordable

Another benefit is how affordable you’ll find a high-quality rubber pond coating. They’re sold at most home improvement stores, too, so you shouldn’t have any trouble finding them in your area, either.

They Work with Just About Any Material

A lot of people use concrete for their manmade ponds, but other options exist, as well. Whichever you choose, you’ll find that a rubber pond coating is able to adhere to the material and do its job.

Safe for Plants and Fish

Furthermore, you may wish to grow plants in your pond (they’re great for looks and keeping the water clean) and/or add fish. The nice thing about using a rubber coating for your pond is that it’s nontoxic. Even if you have no plans for plants or fish, you don’t want local wildlife turning up dead in the water because of toxicity.

Easy to Apply

Installing your own manmade pond isn’t very difficult. You basically dig a hole, pour concrete, add sealant and then your coating. Obviously, it depends on how large the pond is going to be, but the point is that adding a coating is extremely simple to do.
It’s just like painting a wall. You can use a paint roller and brushes to coat the entire surface of your pond and you’ll find it dries relatively quickly. Just make sure you wear a paper mask and put on some gloves before doing so as you don’t want to get any on your skin or breathe in the fumes.

Although there are a number of different ways you can seal in the water in your pond, it’s hard to argue there’s a better way than using the rubber coating we described here. Aside from its affordability, you’ll find that applying a rubber pond coating couldn’t be easier. It will also grant you as much flexibility as you need to create the exact shape you want for your pond.

What to Look for With Pond Liners

Choosing the right pond liners does not have to be a difficult job. You simply need to know the main things to look for no matter the type of liner you choose. This will help to ensure that you are getting a quality pond liner that will work for your needs and your budget. The following are some of the most important aspects you will need to consider when you are searching for the right liner for your pond.

Safe for Fish and Plants

Unless you are using the pond solely as a water feature, you need to consider whether it is safe for fish and plants. Many people like to add plants to give their ponds a more natural look, and they may want to add fish as well. Always make sure that the liner, as well as other items you use, such as sealants, are going to be safe for the living things that you are going to put into the water.

Flexibility and Design Options

You probably have a good idea of the basic design that you would like for your pond. Now, you have to find a liner that is able to accommodate it. Many of the rigid plastic liners are limited in what they are able to do in terms of shape, as well as size. Rubber options, such as EPDM have much more flexibility, and these could be a better option for many who are looking for pond liners.

The Weather

How will the weather affect the pond liners you are considering? If you live in an area where it freezes during the winter, what is going to happen to the liner? If the area receives an extraordinary amount of sunshine, will it be able to stand up to the UV rays? Again EPDM could be a good option since it can do well in so many different environments. The last thing you want to have happen is to have your liner crack because of the weather.


When choosing your pond liners, you also have to think about how durable it will be over the years. You do not want to have to repair or replace the liner every year or two. You want to choose something that is capable of lasting for many years without causing headaches for you.


Similar to the durability, think about what type of maintenance the liner might need over time. How often will you need to perform maintenance on the liner? High quality liners should need minimal maintenance, and when you do need to make fixes to it, they should be fast and easy. Once you have it installed, the pond should not take up all of your time just getting things to work properly.


You also need to consider your budget for the pond to determine what type of liner you are able to afford. If you find that you can’t get a quality liner now, it might be a better option to wait until you can get a liner that will last.

Consider a Liquid Pond Sealer for Your Pond

When you are thinking about creating a backyard pond to help add to the décor of your backyard, one of the things that you need to consider is how you will be lining the pond that you create. You have a couple of different options. You could pour concrete into the hole where you want to have the pool and then use a Liquid Pond Sealer to ensure that the water stays where it belongs. You could also consider using EPDM, or you might want to consider using a premade liner for the pond. Often, what you choose will depend on your preferences, your budget, and how much work you are able to do on your own.

Benefits of Liquid Pond Sealer

Using this type of sealer will offer you a number of benefits. They tend to last quite a bit longer than a typical liner, and they have more flexibility. When you use a premade liner, you are limited to the shapes and sizes they have available. With this type of pond sealer, you can simply brush it on and it will conform to the shape of the concrete pond that you pour. They can work just as well for water fountains as they do with ponds.

You can apply the sealer to many different types of material as well, not just concrete. It is an affordable option, and it is something that you can do on your own with very little effort. It is flexible, and when you choose high quality liquid pond sealers, you will find that it is entirely safe for plants and fish that you put into your pond.

Some people choose to put in plastic lining on their concrete rather than use a sealer. While this is an option, it has drawbacks when compared to the sealers. For starters, it can be difficult to get the plastic lining, which is essentially a set of sheets, to fit the pond properly. It may not look very good when you are done, and it might not be as attractive as using a liquid pond sealer that you brush onto the material.

Choosing the Sealer

When you are choosing the pond sealer, you need to be very careful about the one that you choose. It is important to find a sealer that is nontoxic and that will be safe to use with the marine life and plants that you have in the pond. You also want to have something that will be easy to use and that will cure in a relatively short time. If the job does seem more involved and you do not feel you could do a good job on your own, you may want to consider hiring a professional to help you.

Many people choose to apply the sealer on their own, which is perfectly fine. It’s a relatively simple DIY job. However, you need to make sure that you follow the instructions closely to ensure it works properly. Using quality sealers will give you peace of mind for your pond, and it will ensure that your fish and plants are safe.

Koi Pond Liner Repair Tips

You will always lose some water in your pond, and most of the time, it is nothing of concern. For example, evaporation, the wind, and splashing can cause the water levels to drop slightly. However, if you notice that your koi pond is losing a substantial amount of water, then you should be concerned. Losing anything more than a couple of inches a week is a problem, and it means that there is probably a leak. You have all of your beautiful fish in the pond, and you do not want anything to happen to them.

The First Step in Koi Pond Liner Repair

The first thing that you need to do when you are looking for a leak is try to find easy fixes. In some cases, you will not have to drain the pond. For example, the liner might have slipped, and that could be causing the leak. Returning the liner to its original position can fix it. Other times, it might be the pumps that are causing a problem.

Make sure you turn off the pumps in the pond to see whether there is a change in the water level afterwards. Of course, you need to be aware of the health of the koi when you do this. Make sure the water is aerated so they can breathe or put them into another location. When your turn off the pumps, mark the water levels so you can measure the change. It is easier than trying to “eyeball” it.

If the water levels stay the same, then the problem is likely with the pumps rather than the koi pond liner. Repairs for the pumps might be as simple as removing debris that is clogging them. In some cases, you may find that the best course of action is to get a new pump.

However, if the water levels still drop, then you know it is a problem with the pond’s liner. Let it sit until is stops losing water, as this will give you a better idea of where the leak is located. Check out the liner and look for holes and cracks during this stage of koi pond liner repair. When you find the leak, you will want to remove the rest of the water from the pond, making sure that you have put the fish in a safe location. Then, you can use a patching kit to repair the crack. Always follow the instructions on your patching kit.

Look for More than One Leak

Keep in mind that you might actually have more than just one leak in your koi pond, so liner repair for all of your leaks is necessary, and you want to do them all at the same time. Always look for multiple leaks so you can take care of them at once. One of the worst feelings is taking care of one leak, refilling the pond, and discovering that there is another leak so you have to do it all over again.

Finding the leak can take time, but with a little effort, you can do it, and then you can complete the Koi pond liner repair. If you need help, you may want to contact the professionals.
