The detachable concrete bowl of my bird bath has developed a couple of small holes about 2-3mm in diameter. It does have some sentimental value so would like to repair it if possible. I was thinking drilling a slightly larger hole from the underside and then filling. However I'm struggling to find something to use; either the epoxy stuff isn't recommended for continuous contact with water or is toxic for aquatic use
Any suggestions please of suitable products available in small quantities
