Answer #1 · Maple Tree's Answer · Hi Tim-Depending on what material the birdbath is made of will determine what should be used to fix the crack. If the crack is hindering the integrity of the birdbath's structure and you feel it may come apart it will have to be repaired before sealing the birdbath against any leakage. If this is the case let me know the birdbaths material (concrete, plastic, fiberglass, glass, etc.) and I will look for a proper adhesive to use.

If the only problem is water leakage from the crack you can use silicone adhesive sealers. 100% RTV Silicones work well in sealing cracks in most materials. This silicone is used in the manufacturing of aquariums and sealing around plumbing on liner pools. It will not contaminate the water. Make sure you are using a well known brand of silicone such as Dow Corning, American Sealants, or GE. These sealants cure at a slower rate and don't have any additives to help the sealant dry faster. Many off brands sold at the big box stores are not 100% silicone and are not approved by the USDA and the FDA. Anything not approved for using around human drinking water or food I don't believe should be used around animal food sources also. Any silicone that states that it can be painted after curing should not be used. These silicones have added ingredients and are not 100% silicone and not safe for aquariums or your birdbath. Besides silicones there are epoxy sealers that can be used also, but not as easily applied. Good hardware stores, Pond or water garden supply stores, and pet stores are your best choices for finding these sealers that are not toxic to fish which would keep the birds safe also.

Hope this has helped. If anything else other than sealing a small crack is needed you can upload a picture of the birdbath. This may help in knowing what materials if any could be used to keep the birdbath usable. Above this answer and to the right of your name you will see where you can upload a picture.

You're very welcome. Glade it did the trick for you. I try and fix anything I can in the garden especially if its something I have had for a long time and it looks good with the surroundings. I'm one of those that can't throw anything away.

You're very welcome. Most of the silicone I have used for sealing small water features I have made through the years have been clear in color. Depending on the size of the crack you may check and see if there is a grey colored sealer available at the pond or water garden stores. I know they carry sealers for ponds in different colors that you could also use if you decided to seal the crack and then paint the complete bowl of the birdbath. Just a thought. Take Care and please ask if you have any other questions.
