A penetrating sealer is a water- or solvent-based liquid that penetrates into the concrete, filling the pores and creating an invisible barrier against water, stains, and other sources of damage.

Because they don’t form a film on the surface, penetrating sealers won’t change the appearance or slip resistance of the concrete, making them ideal for interior or exterior surfaces that will be subject to heavy traffic.

When choosing a penetrating sealer, be sure to select one that is compatible with your specific type of concrete. You can consider the following products:

How to Choose the Best Concrete Fountain Sealer?

How to Choose the Best Concrete Fountain Sealer

A concrete fountain can be a beautiful addition to any home or garden and provide the soothing sound of running water. Choosing the best concrete sealers for your fountain will help to protect it from the elements and keep it looking its finest for a long time to come.

There are a few factors to consider when choosing a sealer, such as concrete type, climate, and protection level. Below are some tips for choosing the right concrete sealer.

Type of Fountain Concrete

There are two main types of fountain concrete, Portland cement, and precast concrete. Portland cement is the most common type of concrete and is used in a wide variety of applications. It is made by mixing water, sand, aggregate (rocks or gravel), and Portland cement.

Precast fountain concrete is made by casting concrete into a mold. It is then left to cure or harden. Precast concrete is often used for structural elements, such as walls, columns, and beams.

To determine the type of concrete you have, consult a professional or look for the stamp on the concrete.


The climate in which the concrete is located will also play a role in choosing a sealer. If the fountain is located in an area with high humidity, it is wise to choose a sealer that is resistant to mold and mildew.

In areas that experience extreme temperatures, like direct UV sunlight or freezing temperatures, select a sealer that can withstand extreme conditions.

Desired Level of Protection

If you are looking for a sealer that will provide a high level of protection, such as waterproofing, you will need to choose a fountain concrete sealer that is designed for that purpose. Some sealers are designed to simply provide a barrier against dirt and dust.

Others, like epoxy-based sealers, provide a high level of protection against water and other liquids. But, they can be more difficult to apply and may require the help of a professional.

To understand the different types of concrete sealers for fountains and their benefits, speak with an expert or read the product label.

Eco-friendly Ingredients

The best concrete fountain sealers will contain eco-friendly ingredients that are safe for both humans and the environment. Water-based sealers are a good choice as they do not contain any harmful chemicals or VOCs (Volatile Organic Compounds).

Their natural waxes provide a barrier against water and other liquids without the use of harsh chemicals. They are also easy to apply to indoor and outdoor projects. Check the label for green certifications to ensure the sealer you choose is eco-friendly.

Quantity and Coatings

The quantity of sealer you need will depend on the size and type of fountain you have. Small fountains may only require one coat, while larger fountains may require two or more coats. It is best to consult a professional to determine the right amount of sealer for your project.

Most concrete fountain sealers come in a can or bucket and are applied with a brush, roller, or sprayer. For best results, follow the manufacturer’s instructions on how to apply the sealer.

How Do You Resurface a Concrete Fountain?

How Do You Resurface a Concrete Fountain

A concrete fountain can add a decorative touch to any yard or garden. But over time, the concrete can become stained, cracked, or chipped. If your fountain needs a makeover, resurfacing it with new concrete is a great way to give it a fresh look.

The first step is to remove any old sealer or paint from the fountain’s surface. Next, use a power washer to remove any grime. Once the fountain is clean, apply a bonding agent to the surface. This will help the new concrete to adhere to the old surface.

Finally, mix up a batch of concrete and use a trowel to apply it evenly over the entire fountain. Allow the concrete to dry for 24 hours before adding water.

Why Is My Concrete Fountain Leaking?

Leaking fountains are a common problem, but fortunately, there are many ways to fix them. The most common cause of leaks is a crack in the foundation. It can also be caused by overgrowth, small leaks, weather, and design mistakes.

These problems can be easily fixed in most cases by simply sealing the cracks. For more serious leaks, you may need to consult a professional. But use a sealer as the first line of defense against leaks, as it will help to fill any small cracks and prevent new ones from forming.

Do I Need To Seal the New Concrete Fountain?

It’s a good idea to seal your concrete fountain, especially if it’s new. Sealing helps to protect the concrete from weathering, staining, and wear. It also makes it easier to clean.

Sealing also helps to prevent mold, algae, and mineral buildup and protects the concrete from sun damage. Although it’s not strictly necessary to seal a fountain every year, doing so will help to prolong its life.

Is Epoxy Concrete Sealers Good?

Yes, but it really depends on what you’re using it for. If you’re looking for a sealer to use on concrete fountains, we recommend our listed sealers. They are specially formulated to resist water damage while still allowing the concrete to breathe.

But if you’re looking for a sealer for another project, such as a countertop or floor, epoxy concrete sealers are a good option. Just be sure to read the label carefully to make sure it’s compatible with your project.
