How to Protect a Concrete Birdbath

Quck answer

To seal a concrete birdbath, you will need the following materials: concrete sealer, paintbrush or roller, and a clean, dry cloth.

1. Clean the birdbath thoroughly to remove any dirt or debris. Use a mild detergent and water to scrub the surface, then rinse it off and let it dry completely.

2. Apply the concrete sealer evenly to the entire surface of the birdbath. Use a paintbrush or roller for larger areas, and make sure to cover all the nooks and crannies.

3. Allow the sealer to dry according to the manufacturer’s instructions. This usually takes a few hours or overnight.

4. Apply a second coat of sealer if desired for added protection. Let it dry completely before using the birdbath.

5. Wipe off any excess sealer with a clean, dry cloth.

By following these steps, you can effectively seal your concrete birdbath, protecting it from the elements and ensuring its longevity.


A concrete birdbath is a great addition to any garden and provides a refreshing spot for birds to drink and bathe. However, over time, concrete birdbaths can become stained, pitted, and cracked due to various factors such as algae, mildew, bird droppings, and the freeze-thaw cycle during winter. To prevent these problems, it is important to seal the concrete birdbath.

When selecting a concrete birdbath sealer, it is crucial to choose a product that is safe for birds. Opt for a nontoxic penetrating sealer for porous concrete surfaces. If your birdbath has been painted or previously sealed, use a nontoxic polyurethane sealer. This simple project does not require much time, but you will need to allow sufficient drying time, which may take a few days.

Things You’ll Need

  • Nontoxic all-purpose cleaner or nontoxic concrete cleaner

  • Scrub brush

  • Garden hose

  • Drop cloth or large piece of cardboard

  • Nontoxic penetrating concrete sealer or nontoxic polyurethane sealer

  • Paintbrush

How to Protect a Concrete Birdbath

Step 1: Clean the Birdbath

If you have a new birdbath, clean it thoroughly using a nontoxic all-purpose cleaner (such as citrus or vinegar cleaner) and a scrub brush. For tougher stains, use a nontoxic concrete cleaner following the product instructions. Rinse the birdbath multiple times with a garden hose to remove all traces of the cleaner.

Step 2: Dry the Birdbath

Allow the birdbath to dry in the sun for the entire day or move it to a covered work area for drying. Ensure that all moisture has evaporated from the concrete before applying the sealer.

Step 3: Apply the Sealer

Take the birdbath to a dry and warm space suitable for painting (typically at least 50 degrees Fahrenheit, but refer to the sealer can for specific instructions). Place the birdbath on a drop cloth or a large piece of cardboard. Shake or mix the sealer according to the instructions. Apply the first coat of sealer using a paintbrush and allow it to dry before applying the second coat. Drying time can vary from 30 minutes to several hours depending on the product, so be sure to check the instructions.

Step 4: Ensure Complete Drying

Allow the sealer to dry for at least 48 hours before filling the birdbath with water. Check the surface to ensure it is not sticky and sprinkle water on it to ensure it beads up. If the concrete still absorbs water, you may need to wait for it to dry and then apply a third coat of sealer. Once fully cured, place your birdbath back in the garden for the birds to enjoy.
