The thing to Consider Before When Buying Concrete Fountain Sealer

The thing to Consider Before When Buying Concrete Fountain Sealer

Choosing the best concrete fountain sealer for your outdoor water feature can be a daunting task. With so many brands and products on the market, it is important to do your research in order to find the one that is best for you. 

When it comes time to select a concrete fountain sealer, there are several elements that should be taken into account, such as durability, waterproofing ability, UV protection, and cost. 

Durability is an important factor because you’ll want something that will last a long time in order to protect your fountain from damage caused by exposure to rain or other elements like dirt and debris. 

It is also important to consider waterproofing ability; if you intend to use the sealer around fountains with large amounts of water or moisture, then make sure that it has the ability to resist water penetration. Additionally, look for sealers that offer UV protection against sun damage in order to keep your fountain looking beautiful for longer periods of time. 

Finally, always compare prices between multiple brands so that you can get the best deal possible on a quality product.

When choosing between different sealers for your fountain, take into consideration its usage; if it is going to be placed in a place with direct sunlight or high humidity levels then opt for an acrylic-based sealant which provides excellent UV resistance and dampness shielding capabilities. 

On top of this make sure it has a good longevity rating – this will determine how long it takes before reapplication is necessary – so check out reviews online if available. 

When selecting between solvent-based and water-based formulas make sure that they are suitable with any exterior paints being used on the surrounding area; solvent based formulas are sometimes more durable but may not be compatible with certain paints/coatings. 

An additional factor worth considering when selecting a concrete fountain sealer is its environmental impact. Some formulas are made using compounds with potentially harmful ingredients which could affect local ecosystems or even human health if used improperly; look out for those certified as eco-friendly on product labels or online specifications sheets. 

It’s also wise to check whether or not they meet any industry standards – such as ASTM International’s Concrete Sealants Standards – as these indicate safety guidelines have been adhered too during production processes. 

Lastly, make sure you read all instructions about how long sealing should last and how often it needs reapplication – failure to comply with manufacturer’s guidelines may result in voiding any warranties associated with the product!

Does Flex seal work on concrete fountains?

Does Flex seal work on concrete fountains

Flex Seal can be used to seal concrete fountains, although it is not the most effective option for a long-term solution. It is best suited for shorter-term repairs and maintenance. Before applying Flex Seal, make sure the fountain’s surface is clean, dry and free of debris. 

Use a wire brush or putty knife to scrape away any loose material such as dirt or paint. Next, use a damp cloth to remove any dust particles from the surface of the fountain before applying Flex Seal. Let the fountain dry completely before you begin spraying. 

Once everything is ready, shake up your can of Flex Seal and spray evenly onto the fountain’s surface in smooth strokes. Make sure each coat dries completely before adding more layers if needed.

How do I protect my concrete fountain?

Protecting a concrete fountain is an important step to ensure it has a long life and is watertight. The best way to protect a concrete fountain is with a sealer designed for masonry surfaces. You should always check with the manufacturer or product label to make sure it is suitable for your particular fountain before applying any sealer. 

Concrete fountains should be sealed every two years in order to maintain their protection and waterproofing properties. Before you start sealing, it’s important that the fountain is clean, dry, and free of dirt and debris. 

To apply the sealer, use a brush or roller to evenly spread the sealant over the entire surface of the concrete fountain taking care to avoid any puddles or drips. After the sealant has been applied, allow it to cure completely before adding water.

Can I put bleach in my concrete fountain?

Can I put bleach in my concrete fountain

It is not recommended that you put bleach into your concrete fountain as it can cause damage and discoloration over time. Bleach may also react negatively with other materials used in your fountain such as metals or plastics that can be corroded by its chemicals. 

Your best option would be to use a cleaning solution specifically made for masonry surfaces instead of bleach, which will be much gentler on your fountain while still giving good results.

What kind of paint do you use on a concrete water fountain?

When painting a concrete water fountain, you will want to use an exterior paint specifically designed for masonry surfaces like stucco or brick walls. 

These types of paints are usually made from acrylic-based latex formulas that are resistant to fading from sunlight and weather exposure as well as providing excellent adhesion properties so they won’t peel off easily once applied properly. 

Make sure you thoroughly clean the surface first before applying any primer or paint in order for maximum adhesion and coverage. Once painted, apply several coats of varnish on top of the paint color in order to create a protective layer that will further defend against fading and wear outdoors.


Finding the right sealer for your concrete fountain is an important step towards preserving its beauty and protecting it from damage. It is important to choose a quality sealer that is designed specifically for concrete fountains in order to maximize its effectiveness. 

When selecting a product, make sure it has appropriate VOC levels so that it won’t harm the environment or those living nearby. 

Additionally, be sure to follow proper application instructions and maintenance tips in order to maximize the effectiveness of your sealant. With these tips in mind, you should have no problem finding the best concrete fountain sealer for your needs!
