Mosaic Birdbath on solid concrete stand and top. I use a marine adhesive and outdoor grout that I color based on your choice. For this one I used a combination of blue, green and purple glass nuggets and the bottom on the tray is a soft sea blue going into the tray is a soft ocean green. The base I painted more of a teal green. I added penetrating sealer to the grout and finished off with a membrane sealer to make it water tight.
Beautiful way to add color and function to your garden. All materials are animal friendly (the adhesives is the same one used for aquariums).
