Create an Eccentric Mosaic Garden Ornament

Step 4 Prep the Surface

The surface of the object that you are going to mosaic needs to be relatively clean. So you should wash it off if it is dirty. The bird bath that I am doing was covered in algae and other gross stuff so I scrubbed it with bleach and hosed it off. It doesn't need to be completely dry before you start mosaic-ing but there shouldn't be any puddles or excessive water.
