Step 11 Sealing

After 72 hours the birdbath can be sealed with a concrete sealer. These sealers are clear and shouldn't change the color of your birdbath. Two coats should do it, but follow the directions on the sealer that you are using. Let dry for at least 24 hours. If you are using an outdoor paint, sealing may not be necessary. Check the label on your paints for further instructions.
