We’ve put together this article to give you some help tips and tricks so you can waterproof a pond using liquid rubber.

Waterproofing a pond is an important step in any pond-building project. If you fail to waterproof your pond, it could result in serious and expensive problems. Waterproofing prevents water from seeping through the soil and protects the structure from water damage. In addition, waterproofing your pond helps prevent rot and mildew that can destroy the wood and other materials used to build it.  

We’ve put together this article to give you some helpful tips and tricks so you can waterproof a pond using liquid rubber. Keep reading to learn more about why liquid rubber is one of the best solutions for your project; as well as what to consider before applying the coating and how much maintenance is required after applying liquid rubber. 

What is Liquid Rubber?

Liquid rubber is a liquid-applied waterproofing sealant. It forms a waterproof barrier that's also UV-resistant, preventing water damage and extending the life of the surface it’s applied to. It can be applied to a variety of surfaces, including concrete, masonry, wood and more. Liquid rubber can be applied by brush, roller or spray to different thicknesses depending on the project’s requirements. Curing and drying time for liquid rubber will vary depending on project type.

Why Use Liquid Rubber to Waterproof a Pond?

Liquid rubber is a highly effective method for waterproofing a pond. Once the coating has been applied and dried, it seals the interior of the pond to prevent any water from leaking out.

A rubberized coating like NeoPond Sealant is often used as a solution for waterproofing a pond because it can expand and contract with changes in temperature without cracking or peeling. This is especially useful if you live in an area prone to significant temperature changes throughout the year.  

Another important factor to consider when waterproofing a concrete pond are the aesthetics. A pond is an attractive addition to your property, but if it’s constantly leaking, it can become a problem. By applying a rubber coating to your pond, and with routine and regular maintenance, you can enjoy this water feature for years to come. 

Things to Consider Before Applying Liquid Rubber

When waterproofing a pond, there are a few things to keep in mind: 

  • First, you must assess the size of the pond to determine how much liquid rubber you will need. 
  • You will also need to decide where you would like to apply the coating. In order to apply a rubber coating, the surface must be clean, dry and free of dust. 
  • Start by brushing off dirt, debris and anything else that may be on the surface. 
  • Next, power wash the surface using a low-pressure stream of water with a mild detergent. 
  • Allow the surface to dry completely before applying the rubber coating.
  • Apply multiple coats of Liquid Rubber NeoPond Sealant for the best results (we advise 3-4 heavy coats).  

How Much Does it Cost to Waterproof Your Pond with Liquid Rubber?

The cost of applying a rubber coating to your pond will depend on the size of your pond. A general rule of thumb is that you will spend $2.50 per square foot of pond surface when applying a rubber coating. For example, a 400-square-foot pond could cost around $1000 to waterproof (this is just an estimate). With a little bit of DIY elbow grease, you can have your new or existing pond sealed and water proofed in no time. 


Liquid rubber is one of the best methods for waterproofing a pond. It forms a waterproof barrier on the surface, keeping water out and the rest of your property dry. NeoPond Sealant is specially designed just for ponds, and with a little bit of investment in sweat equity, you can enjoy that pond for years to come. 

A few things to keep in mind before applying a rubber coating to your pond include: how big your pond is; where you would like to apply the coating; and what surface you are applying it to. Make sure to factor these elements in when purchasing the amount of sealant and other materials you’ll require.
