What can I use to line, or seal off, a concrete bird bath?

by Freewine
I have a concrete bird bath that I love. But when it is filled with water it leaches some kind of red material from the concrete itself into the water. I feel this maybe bad for bathing birds and not good to drink, so I have not put water in it.
Is there some material I can line this bird bath with that won't harm the birds and seal off the concrete?
