If you are getting started in making a mosaic, don't forget to prep your substrate. Prepping your substrate prevents warping. It can also make the colors of your glass more vibrant since it will be glued to a white primed surface. Staining is optional. Instead, you can choose to paint the back of the board to add color to the frame. That can be done either before priming or after grouting a mosaic project.
