What Is Pond Sealer?

Adding a pond to your property gives it a unique aesthetic that no other form of landscaping can match.

That being said, installing an actual pond involves a couple more steps than you may realize. For example, unless you want your pond to turn into an eyesore, you’re going to need pond leak sealer.

Keeping Your Pond Intact

Hopefully, you understand that a pond is not made by simply digging a large hole in your yard. Even if it holds water, it won’t be doing so for long. That water will end up in your soil and large swaths of your yard will die from such a large amount.

The solution to this problem is to use pond sealer. This material essentially creates an impenetrable wall that keeps the water in place.

Another great thing about pond sealer is that it allows you to pick the exact shape you want for this body of water. Depending on your personal preferences and the amount of space you have available, your pond could take on just about any form you have in mind.

Keeping Your Pond Safe for Fish

There are all kinds of materials you could use to seal the border of your customized pond. Unfortunately, many of these would be toxic to fish you may plan on keeping. The same goes for any ducks that stop by or even your pets that may take a dip every now and then.

Modern versions of pond leak sealer are made with the needs of your animals in mind. The companies that make them also understand their products must be safe for plant life, too. They aren’t toxic and they won’t hurt any organism. All they do is keep water in place.

Choose an Actual Pond Sealer, not a Repellant

Some people make the mistake of confusing sealants with repellants. That’s because you often here the former term used when describing the chemical entrusted with “sealing” decks and other structures. These types of chemicals aren’t actually made to permanently keep large amounts of water at bay, though. They’re actually repellants, made to simply block water from the wood until it evaporates.

You can’t use this kind of chemical for your manmade pond. Again, some people have chosen a flimsy liner that they then added sealant to for this purpose. While it may “work” at first, it won’t be long before both barriers give way.

Understanding the Unique Needs of Your Pond

Finally, before you choose a sealer, think about the unique needs of your pond. Put simply, if you have a lot of angles to cover, you’ll want to use rubber. Otherwise, a good epoxy will be best because of its superior bond strength. In fact, 9/10 times, you’ll be better off if you choose a strong epoxy – one that doesn’t suffer from the traditional problems of being brittle.

Take your time with this important decision. Now that you understand what a pond sealer is, you should be better prepared to choose one that will keep your property’s body of water intact forever.

What to Look for in Fish Pond Sealer

Like many people, you may be in the planning stage of installing a pond on your property. Ponds look beautiful and add a unique aspect that will set your lawn apart from those in the surrounding area.

Of course, you can always take things a step further and add fish. Koi and other fish make for fun additions you’ll love showing off to your guests. Just be sure you pick the right fish pond sealer to ensure your new landscaping project doesn’t end up becoming a money pit.

Only Choose an Actual Fish Pond Sealer

Step into any hardware or home improvement store and you’ll find shelf after shelf of sealer. For your purposes, though, you absolutely must go with a legitimate fish pond sealer and nothing else. Otherwise, you run the risk of choosing a chemical that isn’t actually made to put up with the demands of a fish pond.

Furthermore, you could pick a chemical that is actually toxic to your fish and any animals that drink the water. It could be fatal to plants, as well.

Consider the Shape of Your Pond

Next, you need to think about how you’ll apply the chemical to your pond. The main thing to think about is its shape. Many people choose what is known as fish pond paint because their ponds have a number of different slopes and angles. This requires a substance that can be applied just like paint but that will eventually dry into an impenetrable surface.

If you’re going for something simpler, you’ll have more options for your fish pond sealer. The important thing is simply that you consider the shape of your pond before beginning the application process.

Do You Care About the Color?

For some people, the color of their fish pond paint or sealer couldn’t matter less. Still, it can make a big difference in how the body of water looks up close. While most go with a black or blue fish pond paint, take a moment to think about how other colors would look. You can even Google them to see examples. You’d hate to apply a fish pond paint, fill it with water, rocks, fish and plants and then find out that you don’t like the result.

Don’t Apply Your Fish Pond Paint Right Away

We’ll leave you with one final tip, though this has to do with how you’ll actually apply your fish pond sealer instead of how to choose it.

If you’re building your pond with concrete, wait a good four weeks before starting. This will give the concrete enough time to dehydrate and cure. People who hurry the process may actually seal in unwanted residual moisture, which will make your pond less stable.

The only way around this timeframe is to add an accelerator to your concrete mixture before beginning on your pond.

Once your pond is finished, your landscaping will have a truly beautiful feature that sets your yard apart and gives your guests something to talk about. Just make sure you handle this vital step correctly before you get too far into the process.

How to Apply Pond Paint

Before you can have a beautiful manmade pond on your property, you’re going to need to paint it. Fortunately, the following steps are fairly easy.

Choose Your Pond Paint Wisely

Before we get into the actual steps of applying your pond paint, let’s take just a moment to talk about choosing the actual product. No matter how well you apply it, if you pick a lackluster paint, the rest of your pond is going to fail and you’ll need to start the entire process over.

First, make sure the product you purchase is meant for ponds. Normal sealers and sealants for wood or fixing leaks are not what we want here. The duress of holding this much water at bay is something only a legitimate pond paint can do.

Second, look for one that is made for whatever material you’re using to build your pond. In most cases, this is going to be concrete. Either way, check the label to make sure that the paint you’re going to use is designed to bond to the materials your pond is made from.

Don’t Touch Concrete for Four Weeks

Unless you added an accelerator to your concrete (assuming you’re using this for your pond), don’t add paint to it until four weeks after it’s been set. The material must cure or you’ll seal in residual moisture, which will eventually cause cracks. Again, you’ll need to start over or, at the very least, carry out some serious repairs if this happens.

If you did add an accelerator to your concrete, you’ll only need to wait about seven days before you can begin painting.

Clean Your Pond

Before getting started, you have to make sure that your pond is both dry and clean. You don’t want to seal any debris in or anything else that will cause problems for your concrete.

Use a shop vac to remove any dust or debris. Then scrub the surface of the pond with warm water and liquid soap before rinsing it all off with a garden hose.

While you do this, check to make sure there aren’t any cracks already appearing. It’s unlikely, but you’re better off finding them now before you apply your pond paint.

Apply Your Sealer

Before your paint, go ahead and apply your sealer. This is usually done with a paintbrush or roller, just as you would do for any other surface. Once it’s applied, let it dry before proceeding with your pond paint.

Apply Your Pond Paint

Speaking of which, the next step is to apply your paint to the surface of your pond. You can use a paint roller or brush for this, whichever you prefer. Just make sure you use broad, even strokes.

We also recommend you wear a paper breathing mask and some gloves. You don’t want to breathe in the chemicals or go through the trouble of getting it off your hands. Remember, this is a form of paint that’s not supposed to let go.

As you can see, the process isn’t overly difficult, but that’s all the more reason to make sure it gets done right. Follow these easy steps and you’ll have no problem applying paint to your pond.

An Introduction to Pond Coatings

Manmade ponds make absolutely beautiful additions to any property – commercial or residential. There are also a number of ways you can customize them, including the addition of various types of fish.

However, one feature you can’t afford to do without is making sure that the surface of the pond is coated properly before proceeding with adding the water. In this article, we’ll explain pond coatings so you understand their importance and feel confident in choosing one for your body of water.

What Are Pond Coatings?

Pond coatings are the chemical barriers used between the material that forms the basin of ponds (usually concrete) and the water itself. Without one, your pond’s foundation is going to leak. It will only be a matter of time before the water and its immense weight finds a weak point and opens a crack. With any luck, it will be a small one you catch early on. Otherwise, the repairs required for fixing it are going to be a lot of work.

Picking the Right Coating for the Job

There are all kinds of products out there these days that provide various types of seals to protect against the type of problem we just described.

However, only pond coatings are to be trusted. Don’t use a sealant that’s meant for traditional applications or any other type of product not specifically designed for a manmade lake. They simply cannot do the trick.

Applying Your Coating

If you decide to do it yourself, there are a few important steps involved with applying a coating. Fortunately, it’s not very difficult at all.

The first thing you must do is simply let the concrete cure. You don’t want any residual moisture causing the concrete to crack or otherwise become weak, as your pond will quickly destroy it.

This can take about four weeks, but if you use an accelerator while the concrete is mixing, it will be more like one.

Next, clean the concrete thoroughly. This means using a vacuum to get rid of any debris that would stand between the coating bonding with the concrete. You should then scrub the surface with warm water and soap using a brush. Again, you don’t want anything – even dust – becoming an issue later on.

Finally, when the concrete is dry again, you can begin the application. Most pond coatings are easiest to apply with a roller brush. Wear a paper mask and gloves when you do this. You don’t want to breathe in the chemical and you also don’t want something this strong touching your skin. It can cause irritation and will be difficult to remove.

Filling Your Pond

Read the label on your coating to find out how long it takes to dry. Only after this amount of time has passed, should you proceed with adding water to your manmade pond. Obviously, if you wish to add plants or other fixtures, you’ll need to do this at some point, too.

Benefiting from a pond coating isn’t difficult, but it is necessary to get right the first time. With the above information read, you should now be in a much better place to do so.

What to Look for in a Pond Sealant

Installing a pond on your property is an undeniable way to improve its aesthetics in a truly unique way. The good news is that, unlike a pool, once the initial installation is done, you don’t need to do a lot in the way of maintenance.

However, this is only if you do it right. Amongst other things, this means using pond sealant and understanding what to look for before making your decision.

Easy Application

If you’re going to be applying pond sealant yourself, then it should go without saying that you want a brand that will be easy to apply. This means choosing a liquid pond sealer. Now, as you’d probably expect, every company will claim theirs is the best for this purpose, so you’ll need to do some research.


The most important thing about this research is finding out what people who have a similar design in mind used for their pond sealant. If you’re just sealing a simple oval shape, that’s going to be a lot easier than if your pond has a less traditional form.

The Right Color

A lot of people will want a black or blue liquid pond sealer, but these aren’t the only two options. These days, you can pick other colors, too, like tan, gray, green, etc.

Again, do a bit of research here. Find out what a certain color liquid pond sealer looks like when applied and sitting under the water. The last thing you want is to go through all the trouble of installing your pond only to find out that the sealant you used gives a funny look.

Safe for Animals and Plants

Obviously, your liquid pond sealer needs to be safe for animals and plants. This is usually a given when it comes to modern brands, but it’s still worth checking for just to be sure.

Keep in mind, this is important even if you have no intention of adding fish to your pond. You don’t want your pets drinking the water and getting sick or find that other animals wandered into your yard only to die after doing the same.

A Warranty/Guarantee

Once your liquid pond sealer is applied, you shouldn’t have to think about it for years and years. Look for a brand that guarantees as much and then be sure you’re following the directions exactly so you can hold the company accountable if something ends up going wrong.

Flexible and Tough

Most of you are going to want to choose an epoxy for your pond as this material can bond to any number of curves, meaning it will stay in place. At the same time, it’s nice and tough so it won’t break down and let the water through.

When you do your research, look for people who used a certain pond sealant for a body of water similar to what you have in mind and haven’t had any problems whatsoever for years. This is going to be a good sealant to choose.

That’s it. Follow the steps above when choosing your pond sealant and you’ll have no problems to worry about in the future.
