Why Is It Important To Seal A Concrete Bird Bath

Aside from reducing the porosity and preventing leaks from occurring, a sealed concrete bird bath can have a longer lifespan and ensure protection against cracking, water penetration, and the accumulation of fungus, mold, and mildew.

A sealant can also help prevent the bird bath from holding viruses and infections that lead to the birds contracting diseases.

How To Apply Sealant To Concrete Bird Bath

If you want to achieve a well-sealed bird bath, it would be best to follow the correct method below:

1. Thoroughly Clean Dirt And Mold

Before you do anything, we suggest you prepare a scrub brush, bucket, and cleaning agent first.

If you are not a fan of commercial cleaners, you can use vinegar or citrus to clean your bird bath. But if your bird bath has too many stains and is covered with mold and mildew, it would be best to utilize a more robust cleaning solution, like a non-toxic concrete cleaner.

If you choose the latter, please check the instructions on the manual, so you can use it correctly and prevent damaging the bird bath.

After brushing and cleaning the bird bath completely, rinse it thoroughly. Ensure that you have completely washed out the cleaner.

2. Dry Completely

Before sealing the bird bath, you should let it dry out thoroughly. There are two things you can either do for this step.

  • One, you can let your bird bath dry out in direct sunlight.
  • Second, allow it to air dry.

3. Seal The Bird Bath

For the sealant application step, you must ensure that the temperature lies at least 50 degrees Fahrenheit. However, some concrete sealants have their considerations, so it is still best to check the application instructions.

Place the bird bath on top of a newspaper or cardboard to catch all the excess or dripping sealant later.

Apply the first coat of the sealant and let it dry before you paint the second coating. The typical drying time of concrete sealants can be anywhere between 30 minutes to an hour.

4. Let Sealant Dry Completely

In this step, it would be best to let the bird bath dry for at least two days. And to ensure that it is perfectly dry, you can try to sprinkle water on it and see if it is beading.

On the other hand, if it is still penetrating water, you should apply the third coating. Allow it to dry again. Once it becomes dry, place it back in the garden and let the birds enjoy the bird bath.

What Are The Advantages Of A Concrete Bird Bath?


Having a concrete bird bath is a wise choice since it can provide the following benefits:

What Are The Drawbacks Of A Concrete Bird Bath?


It is inevitable for a concrete bird bath to have drawbacks. Let’s find out these things and see if they can outweigh their benefits.


Bird baths are indeed visually appealing ornaments. However, they are heavy, so expect you to have difficulty moving them from one place to another. You will also have trouble cleaning it and moving it into storage.

Easily Accumulate Algae

Porousness is the main reason why you should seal your concrete bird bath. Since concrete is permeable, algae growth is inevitable, especially if you don’t clean it regularly.

Prone To Leaks

If you don’t take care of your bird baths correctly, especially during cold seasons, it can quickly obtain cracks and chips, leading to leaks.

Since we have mentioned that maintaining your bird bath is a must to lengthen its lifespan, we will provide you below with some tips you should do to achieve its best condition:

  • Regularly clean the bird bath to prevent algae from accumulating and making the water toxic to birds.
  • You can place the bird bath in a shady area to reduce evaporation.
  • You can keep a cleaner bath for longer if you place it away from feeders.
  • Regularly refill the bath by disposing of the old, stagnant water and replacing it with clean water.
  • Before you refill the water, using a pressure washer at its lowest setting would be best to quickly rinse the bird bath.
  • You should also consider placing the bird bath away from the reach of pets and children to avoid contaminating the water.
  • As much as possible, ensure that you place the bird bath away from falling leaves, grass cuttings, and other dirt- and debris-producing items.
  • Do not let the water in the bird bath get low since this could lead to a buildup of harmful contaminants.
  • Store your bird bath inside your garage during winter if you want to protect them from chipping and cracking. You can also cover it with plastic if you don’t want to move it inside. You have to use at least three layers of plastic. Lastly, ensure the bird bath is clean and completely dry before overwintering it.
  • Place the bird bath on a flat surface and away from heavy traffic areas where it could be knocked or topple over.
  • You can opt to add enzymes into the water of your bird bath. Check and purchase one in a pet shop near you. These enzymes can help in reducing mold growth.
  • Add copper coins to your bird bath’s water to keep it clean and fresh. Read more about: ”Do Pennies Keep A Bird Bath Clean?”

What Is The Importance Of Cleaning A Bird Bath?


Just like humans, birds don’t wish to drink water that is dirty, toxic, and full of bacteria. Birds also need care and protection against pollutants and diseases, so it would be best to keep the bird bath clean.

Additionally, a clean and algae-free bird bath can prevent mosquitoes, gnats, and other insects from populating the water inside the bath, which can lead to diseases and harm humans.

Ignoring a dirty bird bath will also lead to an awful water odor and stains that are hard to remove, or worse, can be permanent, and you might never restore it to its original color and beauty.

Furthermore, keep in mind that a clean bird bath and water can encourage more birds and bring safety to all wildlife.
