You can use Mod Podge to seal anything that goes outside. As long as its the waterproof Mod Podge. I've painted & sealed a few things (plant pots/ ornaments/ rocks) and coated in 3/4 coats of Mod Podge and always lasted. It dries clear too. Here's the link:

I've got a large concrete bird bath which was a grey colour. I used Wickes Masonry Smooth Sandstone paint and dabbed it on. It looks good and it's weatherproof. It looks just like this which I found on the internet https://www.gumtree.com/p/pots-ornaments/double-bird-bath-feeder/1409779686
